A shiny gray element with atomic symbol As, atomic number 33, and atomic weight 75. It occurs throughout the universe, mostly in the form of metallic arsenides. Most forms are toxic. According to the Fourth Annual Report on Carcinogens (NTP 85-002, 1985), arsenic and certain arsenic compounds have been listed as known carcinogens. (From Merck Index, 11th ed)
Disorders associated with acute or chronic exposure to compounds containing ARSENIC (ARSENICALS) which may be fatal. Acute oral ingestion is associated with gastrointestinal symptoms and an encephalopathy which may manifest as SEIZURES, mental status changes, and COMA. Chronic exposure is associated with mucosal irritation, desquamating rash, myalgias, peripheral neuropathy, and white transverse (Mees) lines in the fingernails. (Adams et al., Principles of Neurology, 6th ed, p1212)

Arsenic trioxide and melarsoprol induce apoptosis in plasma cell lines and in plasma cells from myeloma patients. (1/242)

Recent data have renewed the interest for arsenic-containing compounds as anticancer agents. In particular, arsenic trioxide (As2O3) has been demonstrated to be an effective drug in the treatment of acute promyelocytic leukemia by inducing programmed cell death in leukemic cells both in vitro and in vivo. This prompted us to study the in vitro effects of As2O3 and of another arsenical derivative, the organic compound melarsoprol, on human myeloma cells and on the plasma cell differentiation of normal B cells. At pharmacological concentrations (10(-8) to 10(-6) mol/L), As2O3 and melarsoprol caused a dose- and time-dependent inhibition of survival and growth in myeloma cell lines that was, in some, similar to that of acute promyelocytic leukemia cells. Both arsenical compounds induced plasma cell apoptosis, as assessed by 4',6-diamidino-2-phenylindole staining, detection of phosphatidylserine at the cell surface using annexin V, and by the terminal deoxynucleotidyl transferase-mediated nick end labeling assay. As2O3 and melarsoprol also inhibited viability and growth and induced apoptosis in plasma-cell enriched preparations from the bone marrow or blood of myeloma patients. In nonseparated bone marrow samples, both arsenical compounds triggered death in myeloma cells while sparing most myeloid cells, as demonstrated by double staining with annexin V and CD38 or CD15 antibodies. In primary myeloma cells as in cell lines, interleukin 6 did not prevent arsenic-induced cell death or growth inhibition, and no synergistic effect was observed with IFN-alpha. In contrast to As2O3, melarsoprol only slightly reduced the plasma cell differentiation of normal B cells induced by pokeweed mitogen. Both pokeweed mitogen-induced normal plasma cells and malignant plasma cells showed a normal nuclear distribution of PML protein, which was disrupted by As2O3 but not by melarsoprol, suggesting that the two arsenical derivatives acted by different mechanisms. These results point to the use of arsenical derivatives as investigational drugs in the treatment of multiple myeloma.  (+info)

Health impacts of domestic coal use in China. (2/242)

Domestic coal combustion has had profound adverse effects on the health of millions of people worldwide. In China alone several hundred million people commonly burn raw coal in unvented stoves that permeate their homes with high levels of toxic metals and organic compounds. At least 3,000 people in Guizhou Province in southwest China are suffering from severe arsenic poisoning. The primary source of the arsenic appears to be consumption of chili peppers dried over fires fueled with high-arsenic coal. Coal samples in the region were found to contain up to 35,000 ppm arsenic. Chili peppers dried over high-arsenic coal fires adsorb 500 ppm arsenic on average. More than 10 million people in Guizhou Province and surrounding areas suffer from dental and skeletal fluorosis. The excess fluorine is caused by eating corn dried over burning briquettes made from high-fluorine coals and high-fluorine clay binders. Polycyclic aromatic hydrocarbons formed during coal combustion are believed to cause or contribute to the high incidence of esophageal and lung cancers in parts of China. Domestic coal combustion also has caused selenium poisoning and possibly mercury poisoning. Better knowledge of coal quality parameters may help to reduce some of these health problems. For example, information on concentrations and distributions of potentially toxic elements in coal may help delineate areas of a coal deposit to be avoided. Information on the modes of occurrence of these elements and the textural relations of the minerals and macerals in coal may help predict the behavior of the potentially toxic components during coal combustion.  (+info)

Increased chromosome-type chromosome aberration frequencies as biomarkers of cancer risk in a blackfoot endemic area. (3/242)

To examine whether biomarkers such as sister chromatid exchanges (SCEs) and chromosome aberrations (CAs) can predict cancer development, a nested case-control study was performed in a blackfoot endemic area with a known high cancer risk. A cohort of 686 residents was recruited from three villages in the blackfoot endemic area. Personal characteristics were collected, and venous blood was drawn for lymphocyte culture and stored in a refrigerator. The vital status and cancer development were followed using the National Death Registry, Cancer Registry, and Blackfoot Disease Registry. The follow-up period was from August 1991 to July 1995. During this 4-year period, 31 residents developed various types of cancer. Blood culture samples from nine of these subjects were unsuitable for experiments due to improper storage. Finally, a total of 22 cancer cases had cytogenetic samples that could be analyzed. Twenty-two control subjects were selected from those who did not develop cancer in the study period, and these subjects were matched to cases by sex, age, smoking habits, and residential area. The results showed that there was no significant difference in the frequencies of SCE and chromatid-type CAs between the case and control groups. However, the frequencies of chromosome-type CAs, e.g., chromosome-type gaps, chromosome-type breaks, chromosome-type breaks plus exchanges, total chromosome-type aberrations, and total frequencies of CAs in the case group, were significantly higher than those in the control group (P < 0.05). The odds ratio of cancer risk in subjects with more than zero chromosome-type breaks was 5.0 (95% confidence interval = 1.09-22.82) compared to those with zero chromosomal breaks. The odds ratios for more than zero chromosome-type breaks plus exchanges and a frequency of total chromosome-type aberrations of >1.007% were 11.0 and 12.0, respectively (P < 0.05). Subjects with a total CA frequency of >4.023% had a 9-fold increase for cancer risk. These results indicate that chromosome-type CAs are good biomarkers for the prediction of cancer development, whereas SCEs and chromatid-type CAs cannot predict cancer risk.  (+info)

Testing their metal. (4/242)

Metals continually rank at the top of the U.S. Environmental Protection Agency's annual list of agents that pose the greatest hazard to the people of the United States. Metals aren't going away, either. They do not biodegrade, and they often concentrate in human and animal cells and tissue. Many metals are known human and animal carcinogens, while many others are suspected to play a role in cancer. Little is known, however, about the mechanisms by which metals cause cancer.  (+info)

The development of Lewisite vapour induced lesions in the domestic, white pig. (5/242)

Studies performed in the past in our laboratory have detailed the development of sulphur mustard lesions in the domestic, white pig using small glass chambers to achieve saturated vapour exposure under occluded conditions. We have now used this experimental model to produce cutaneous lesions for detailed histopathological studies following challenge with lewisite. Histological examination of resulting lesions have revealed that although the overall pattern of lesion development is similar to that seen following mustard challenge, the time-course of cellular events is very much compressed. The epidermis showed focal basal cell vacuolation with associated acute inflammation as early as one hour postexposure. Coagulative necrosis of the epidermis and papillary dermis was complete by 24 hours and followed the appearance of multiple coalescent blisters between six and 12 hours post-exposure. At 48 hours, the lesions were full thickness burns with necrosis extending into the deep subcutaneous connective and adipose tissues. The study of lesions beyond 24 hours revealed early epithelial regeneration at the wound edge. The overall spontaneous healing rate of these biologically severe lesions was significantly faster than comparable sulphur mustard injuries and probably reflected a lack of alkylation of DNA and RNA.  (+info)

Arsenic-related Bowen's disease, palmar keratosis, and skin cancer. (6/242)

Chronic arsenical intoxication can still be found in environmental and industrial settings. Symptoms of chronic arsenic intoxication include general pigmentation or focal "raindrop" pigmentation of the skin and the appearance of hyperkeratosis of the palms of the hands and soles of the feet. In addition to arsenic-related skin diseases including keratosis, Bowen's disease, basal-cell-carcinoma, and squamous-cell carcinoma, there is also an increased risk of some internal malignancies. Arsenic-related diseases are common in areas of the world where the drinking water has a high arsenic content. In this paper, we describe a 35-year-old male patient who had arsenic-related keratosis, squamous-cell carcinoma in the palmar area of his left hand, and Bowen's disease on his left thigh. The patient worked in a borax mine for 15 years, so he was exposed to arsenic in drinking water, airborne arsenic in his workplace, and had direct contact. The patient was treated for 11 months for arsenic-related keratosis until an axillary lymph node metastasis occurred; the lesion was excised and diagnosed to be malignant. Bowen's disease was detected when the patient was being treated for cancer. No other malignancy was found. The patient is still receiving regular follow-up care.  (+info)

Enhanced transcription factor DNA binding and gene expression induced by arsenite or arsenate in renal slices. (7/242)

Although the kidney represents a target for the accumulation and toxicity of arsenic, little is known about the molecular targets of arsenic in this organ. Therefore, these studies were designed to examine the molecular impact of arsenite [As(III)] and arsenate [As(V)] at low (nanomolar) concentrations. Precision-cut rabbit renal cortical slices were challenged with As(III) or As(V) for up to 8 h. Neither form of the metal induced overt cytotoxicity as assessed by intracellular K+ levels over this time period at concentrations from 0.01-10 microM. In addition, no alterations in the expression of Hsp 60, 70, or 90 were observed. However, induction of heme oxygenase-1 (Hsp 32) was seen following a 4-h challenge with As(III), but not with As(V). As(III) and As(V) induced DNA binding of AP-1 at 2- and 4-h exposure; following a 6-h exposure there was no difference. Although no alteration in the DNA binding activity of ATF-2 was induced by As(III) or As(V), both forms enhanced the DNA binding activity of Elk-1. Enhanced DNA binding activity of AP-1 and Elk-1 correlated with increased gene expression of c-fos, but not c-jun, at 2 h. c-myc gene expression was also induced by As(III) and As(V), albeit at a later time point (6 h). These results suggest that acute arsenic challenge, by either As(III) or As(V), is associated with discrete alterations in the activity of signaling pathways and gene expression in renal tissue.  (+info)

Relations between exposure to arsenic, skin lesions, and glucosuria. (8/242)

OBJECTIVES: Exposure to arsenic causes keratosis, hyperpigmentation, and hypopigmentation and seemingly also diabetes mellitus, at least in subjects with skin lesions. Here we evaluate the relations of arsenical skin lesions and glucosuria as a proxy for diabetes mellitus. METHODS: Through existing measurements of arsenic in drinking water in Bangladesh, wells with and without arsenic contamination were identified. Based on a questionnaire, 1595 subjects > or = 30 years of age were interviewed; 1481 had a history of drinking water contaminated with arsenic whereas 114 had not. Time weighted mean arsenic concentrations and mg-years/l of exposure to arsenic were estimated based on the history of consumption of well water and current arsenic concentrations. Urine samples from the study subjects were tested by means of a glucometric strip. People with positive tests were considered to be cases of glucosuria. RESULTS: A total of 430 (29%) of the exposed people were found to have skin lesions. Corresponding to drinking water with < 0.5, 0.5-1.0, and > 1.0 mg/l of arsenic, and with the 114 unexposed subjects as the reference, the prevalence ratios for glucosuria, as adjusted for age and sex, were 0.8, 1.4, and 1.4 for those without skin lesions, and 1.1, 2.2, and 2.6 for those with skin lesions. Taking exposure as < 1.0, 1.0-5.0, > 5.0-10.0 and > 10.0 mg-years/l of exposure to arsenic the prevalence ratios, similarly adjusted, were 0.4, 0.9, 1.2, and 1.7 for those without and 0.8, 1.7, 2.1, and 2.9 for those with skin lesions. All series of risk estimates were significant for trend, (p < 0.01). CONCLUSIONS: The results suggest that skin lesions and diabetes mellitus, as here indicated by glucosuria, are largely independent effects of exposure to arsenic although glucosuria had some tendency to be associated with skin lesions. Importantly, however, glucosuria (diabetes mellitus) may occur independently of skin lesions.  (+info)

Pilot study indicates that dogs eating rice-based dry dog foods could be at risk for chronic arsenic exposure. Rice-consumption is considered a risk factor for chronic arsenic toxicity in humans. A pilot study conducted within the DogRisk research group at the University of Helsinki found that dogs eating rice-based dry dog foods had higher hair arsenic levels than dogs whose diet did not contain rice. The study compared hair arsenic levels from seven dogs that were eating rice-based (having rice as first or second ingredient) dry dog foods and nine dogs whose diet did not contain any rice. All dogs were of the breed Staffordshire bull terrier and had been eating their diets for a minimum of one year prior to the study.. - Considering that dogs often eat the same food daily for long periods of time, sometimes even their whole lives, we need to acknowledge the risk for long-term accumulation of contaminants such as toxic metals. Arsenic is widespread in the environment and accumulates especially ...

The Binational Arsenic Exposure Survey (BAsES) was designed to evaluate probable arsenic exposures in selected areas of southern Arizona and northern Mexico, two regions with known elevated levels of arsenic in groundwater reserves. This paper describes the methodology of BAsES and the relationship between estimated arsenic intake from beverages and arsenic output in urine. Households from eight communities were selected for their varying groundwater arsenic concentrations in Arizona, USA and Sonora, Mexico. Adults responded to questionnaires and provided dietary information. A first morning urine void and water from all household drinking sources were collected. Associations between urinary arsenic concentration (total, organic, inorganic) and estimated level of arsenic consumed from water and other beverages were evaluated through crude associations and by random effects models. Median estimated total arsenic intake from beverages among participants from Arizona communities ranged from 1.7 to 14.1 µg

Emerging data indicate that rice consumption may lead to potentially harmful arsenic exposure. However, few human data are available, and virtually none exist for vulnerable periods such as pregnancy. Here we document a positive association between rice consumption and urinary arsenic excretion, a biomarker of recent arsenic exposure, in 229 pregnant women. At a 6-mo prenatal visit, we collected a urine sample and 3-d dietary record for water, fish/seafood, and rice. We also tested womens home tap water for arsenic, which we combined with tap water consumption to estimate arsenic exposure through water. Women who reported rice intake (n = 73) consumed a median of 28.3 g/d, which is ∼0.5 cup of cooked rice each day. In general linear models adjusted for age and urinary dilution, both rice consumption (g, dry mass/d) and arsenic exposure through water (μg/d) were significantly associated with natural log-transformed total urinary arsenic ( ...
Ingestion of arsenic is relatively common in the setting of homicide and is occasionally used in deliberate self-poisoning. Arsine gas and CCA exposure are not uncommon industrial exposures. Most organs can be involved and the diagnosis may not be obvious. \\ \\ Arsenic is a classic poison; implicated in the deaths of Tchaikovsky and Napoleon. It has also been used as a therapeutic substance since ancient times. It has been used in traditional Chinese medicines and most recently as a chemotherapeutic agent for the treatment of acute promyelocytic leukaemia. Chronic arsenic poisoning is a major public health crisis and an environmental disaster in Bangladesh and West Bengal, due to the contamination of ground water that affects millions of people. These chronic problems are beyond the scope of this course. \\ \\ Arsenic exists in many forms: arsine gas, elemental arsenic, inorganic oxides and organic arsenic. Acute arsenic poisoning is rare. The elemental form of arsenic is non-toxic but the ...

Inorganic arsenic is a human carcinogen that can target the liver, but its carcinogenic mechanisms are still unknown. Global DNA hypomethylation occurs during arsenic-induced malignant transformation in rodent liver cells. DNA hypomethylation can increase gene expression, particularly when occurring in the promoter region CpG sites, and may be a non-genotoxic mechanism of carcinogenesis. Thus, in the present study liver samples of male mice exposed to 0 (control) or 45 p.p.m. arsenic (as NaAsO2) in the drinking water for 48 weeks were analyzed for gene expression and DNA methylation. Chronic arsenic exposure caused hepatic steatosis, a lesion also linked to consumption of methyl-deficient diets. Microarray analysis of liver samples showed arsenic induced aberrant gene expression including steroid-related genes, cytokines, apoptosis-related genes and cell cycle-related genes. In particular, the expression of the estrogen receptor-α (ER-α), and cyclin D1 genes were markedly increased. RT-PCR and ...
The WHO recommended value of arsenic contamination in water is 0.01 mg/l, while the maximum permissible limit for Bangladesh and India has been fixed at 0.05 mg/l. In the DCH-SOES survey, less than 0.01 mg/l arsenic concentration was detected in 46% or 2803 out of 6101 water samples while above the WHO recommended value (0.01 mg/l) was found in the rest 54% or 3298 samples. On the other hand, arsenic concentration at less than the permissible limit (0.05 mg/l) was detected in 62% or 3783 samples, while above the limit was found in the rest 38% or 2318 water samples. Arsenic contamination at higher level than the WHO recommended value was found in the tube-wells of 52 districts out of the 60 surveyed. Of these, the level of arsenic presence exceeds the maximum permissible limit in the tube-wells water of 41 districts. In 11 districts, the level of arsenic concentration was found more than the WHO recommended value, but less than the maximum permissible limit. That means, highest 0.05 mg/l exist ...
Introduction: Human are exposed to arsenic threats in several ways. Our drinking water for instance, can be hazardous due to the contamination of arsenic-based pesticide and herbicide into our water supply. The most vulnerable part of our body due to ingestion of arsenic is our gastrointestinal system. Thus, the aim of this study was to determine the effects of chronic exposure to organic arsenic (Monosodium methylarsonate, MSMA) on the surface topography of rats colonic mucosa by using scanning electron microscope (SEM). Materials and Methods: 30 Sprague Dawley rats were given daily oral gavage of MSMA 42.13 mg/kg, which is 1/30 LD50, and 30 Sprague Dawley rats acted as control. 10 exposed rats and 10 control rats were sacrificed at regular intervals (2 months, 4 months and 6 months) and their colon specimens were examined by SEM. Results: In the control group, the colonic mucosa appeared normal with uniform size individual glandular units and has a central crypt orifice. The goblet cells were ...
Arsenic dissolved in water is acutely toxic and can lead to a number of health problems. Long-term exposure to arsenic in drinking-water causes increased risks of cancer in the skin, lungs, bladder and kidney. It also leads to other skin-related problems such hyperkeratosis and changes in pigmentation. Consumption of arsenic also leads to disturbance of the cardiovascular and nervous system functions and eventually leads to death. These health effects sometimes collectively referred to as arsenicosis have been demonstrated in many studies. Increased risks of lung and bladder cancer and of arsenic-associated skin lesions have been reported for consuming drinking-water with arsenic concentrations equal to or greater than 50 parts per billion (or microgram per liter). (WHO Environmental Health Criteria, No. 224: Arsenic).. Arsenicosis is recognizable from skin colour changes, blotches all over the face and body, hyper pigmentation on the chest and upper arms, hard patches on palms and soles of the ...
Millions now suffer the effects of chronic arseniasis related to environmental arsenic exposure. The biological mechanisms responsible for arsenic-induced toxicity and especially chronic effects, including cancer, are not well known. The U.S. Armed Forces Institute of Pathology (AFIP) is participati …
Arsenic (As) is an ubiquitous chemical element that occurs in nature in the form of organic and inorganic compounds, and its harmful effects are well known and described. It is well known that inorganic arsenic (III and V) compounds are more toxic than organic compounds. Also the bioavailability of arsenic from different chemical compounds varies. Organic forms of arsenic, which are most commonly found in fish and seafood, undergo little biotransformation after consumption and are excreted from the body in virtually unchanged form. On the other hand, inorganic arsenic compounds are well absorbed and metabolized. Adverse effects of inorganic arsenic Long-term exposure to arsenic derived from inorganic compounds results in an increased risk of developing various types of cancer, including skin, bladder, lung, kidney, liver and prostate cancer. In addition, exposure to inorganic arsenic is accompanied by disorders of gastrointestinal, cardiovascular, blood, respiratory, neurological, immune, ...
Arsenic biochemistry refers to biochemical processes that can use arsenic or its compounds, such as arsenate. Arsenic is a moderately abundant element in Earths crust, and although many arsenic compounds are often considered highly toxic to most life, a wide variety of organoarsenic compounds are produced biologically and various organic and inorganic arsenic compounds are metabolized by numerous organisms. This pattern is general for other related elements, including selenium, which can exhibit both beneficial and deleterious effects. Arsenic biochemistry has become topical since many toxic arsenic compounds are found in some aquifers, potentially affecting many millions of people via biochemical processes. The evidence that arsenic may be a beneficial nutrient at trace levels below the background to which living organisms are normally exposed has been reviewed. Some organoarsenic compounds found in nature are arsenobetaine and arsenocholine, both being found in many marine organisms. Some ...
Arsenic is carcinogenic, possibly partly through epigenetic mechanisms. We evaluated the effects of arsenic exposure and metabolism on DNA methylation. Arsenic exposure and methylation efficiency in 202 women in the Argentinean Andes were assessed from concentrations of arsenic metabolites in urine (inorgani
Arsenic is found in multiple forms, some of which are more toxic to humans than others. In Alaska, most arsenic in groundwater is likely derived from inorganic arsenic that occurs naturally in the Earths crust, most commonly as the mineral arsenopyrite. When arsenopyrite oxidizes into its elemental components (similar to the way iron rusts) and those components enter the groundwater system, the resulting arsenic, as pentavalent arsenic [As(V) or arsenate] and trivalent arsenic [As(III) or arsenite], is toxic to humans. Arsenite is both more harmful and more mobile in groundwater than arsenate. Soils in some parts of Alaska have high concentrations of inorganic arsenic, which can leach into groundwater and render private well water unsafe for consumption. Arsenic in surface water, however, tends to bind with iron oxide and organic material, making it less mobile, and therefore, less likely to reach drinking water sources. Arsenic also accumulates in food crops grown in arsenic-rich soil or ...
The guideline value for inorganic arsenic in drinking water was reduced from 50 μg/L to 10 μg/L by the World Health Organization (WHO) in 1993. Nonetheless, many countries, particularly developing countries, still use the 50 μg/L value as standard for arsenic partially because of lack of adequate analytical instruments for lower arsenic concentrations in water.. Elevated concentrations of arsenic in drinking water (above 50 μg/L) have been reported in several countries, including Argentina, Chile, China, Mongolia, Taiwan, Nepal, Japan, Mexico, Poland, Vietnam, and the USA. Local-scale problems of arsenic contamination of groundwater have been reported by some countries, and new cases are continually discovered - groundwater contaminated by arsenic can be found all over the world.. To date, the globally worst-affected areas are located in Bangladesh and West Bengal (India), where arsenic in groundwater has been documented at concentrations up to 3,200 μg/L. Moreover, in some districts of ...
epigenetic alteration behindenhanced mitochondrial biogenesis in chronic arsenic exposure. An extensive case-control study was conducted with 390 study participants (unexposed, exposed without skin lesion, exposed with skin lesion and exposed skin tumour) from highly arsenic exposed areas ofWest Bengal, India. Methylation specific PCRrevealed significant promoter hypomethylation oftwo key biogenesis regulatory genes, PGC1αandTfam in arsenic exposed individuals and also in skin tumour tissues. Linear regression analysis indicated significant negative correlation between urinary arsenic concentration and promoter methylation status. Increased expression of biogenesis regulatory genes wasobtained by quantitative real-time PCR analysis. Moreover, altered mitochondrial fusion-fission regulatory gene expression was also observed in skin tumour tissues. miR663, having tumour suppressor gene like function was known to be epigenetically regulated through mitochondrial retrograde signal. Promoter ...
This blood test is used to measure Arsenic levels. Arsenic is a common cause of acute poisoning through heavy metals. Arsenic enters the environment through the smelting of copper, zinc and lead and is released through the manufacturing of certain chemicals. Pesticides that contain arsenic, when manufactured, release arsine gas. Arsenic has been found in water supplies around the world, which has the potential to leach into seafood. Arsenic is found in rat poisoning, fungicides and products used to protect wood. Arsenic toxicity affects the blood, kidneys, skin, digestive tract and central nervous system ...
Compounds of arsenic were recognized as highly toxic long before arsenic was even recognized as an element in 1649 (by Schroeder, a German pharmacist). Nero used arsenic to poison Britannicus in 55 AD to secure the Roman throne. In 17th century France, white arsenic (As2O3) was known as poudre de succession (inheritance powder). Today, approximately 90 percent of all arsenic used in the US is used as a wood preservative. Arsenic is also used in electronics (gallium arsenide) and continues to be used in agricultural chemicals (pesticides, insecticides, herbicides, algaecides, fungicides and growth stimulants for plants and animals). Arsenic, being an element, is never destroyed once released into the environment. It will be with us forever.. Arsenic consumption is linked to a number of adverse health effects including skin, bladder and lung cancer. Oxygenated compounds of arsenic (arsenates: As+5 and arsenites: As+3) are soluble in water and, when ingested, mimic phosphates in the body. They can ...
BACKGROUND A large population in West Bengal, India has been exposed to naturally occurring inorganic arsenic through their drinking water. A cross-sectional survey involving 7683 participants of all ages was conducted in an arsenic-affected region between April 1995 and March 1996. The main focus of the study was skin keratoses and pigmentation alterations, two characteristic signs of ingested inorganic arsenic. Strong exposure-response gradients were found for these skin lesions. The study also collected limited information concerning respiratory system signs and symptoms, which we report here because increasing evidence suggests that arsenic ingestion also causes pulmonary effects. METHODS Participants were clinically examined and interviewed, and the arsenic content in their current primary drinking water source was measured. There were few smokers and analyses were confined to non-smokers (N = 6864 participants). RESULTS Among both males and females, the prevalence of cough, shortness of breath

The control of arsenic, a toxic and carcinogenic element, is an important issue for all copper smelters. In this work, the reaction mechanism and distribution behavior of arsenic in the bottom blown copper smelting process (SKS process) were investigated and compared to the flash smelting process. There are obvious differences of arsenic distribution in the SKS process and flash process, resulting from the differences of oxygen potentials, volatilizations, smelting temperatures, reaction intensities, and mass transfer processes. Under stable production conditions, the distributions of arsenic among matte, slag, and gas phases are 6%, 12%, and 82%, respectively. Less arsenic is reported in the gas phase with the flash process than with the SKS process. The main arsenic species in gas phase are AsS (g), AsO (g), and As2 (g). Arsenic exists in the slag predominantly as As2O3 (l), and in matte as As (l). High matte grade is harmful to the elimination of arsenic to gas. The changing of Fe/SiO2 has slight
2000, describes a method for removing arsenic from fly ash, in which arsenic is recovered as scorodite. The first treatment stage of the arsenic-containing material is the oxidation of trivalent arsenic (As(lll)) into pentavalent arsenic (As(V)) with a gas containing sulphur dioxide and oxygen in oxidising conditions, in which arsenic does not precipitate. After this, arsenic is precipitated in atmospheric conditions, in which the Fe(III)/As(V) mole ratio is specified as 1. Precipitation is carried out either in one or several stages, but precipitation as scorodite demands the over-saturation of the solution, which is achieved by recycling scorodite crystals to the first precipitation reactors and simultaneously neutralising the suspension. A beneficial pH range is around 1-2 and this is maintained by feeding a suitable neutralising agent into the precipitation stage. In these conditions, arsenic can be precipitated to the level of 0.5 g/l. The final arsenic removal to a level below 0.1 mg/l is ...
Arsenic contamination of the environment is a worldwide health hazard. This research project focused on four areas: development and testing of low cost, field portable devices capable of measuring levels of arsenic at 10 μg L-1 or less; specific chemical techniques for such testing; creation of educational tools and techniques to allow operators who lack advanced chemistry training to perform accurate testing; and the determination and use of a biomarker in DNA as a cancer predictor in individuals exposed to environmental arsenic. The analytical techniques explored include: (1) the Gutzeit method of arsenic determination though arsine gas production, which was investigated in three experiments: measuring arsenic levels in soil samples, using Gutzeit-based kits using silver nitrate as a reactant for arsine gas, and sensitivity comparison of three commercial test kits over varying time periods up to twenty-four hours. (2) The molybdenum blue method, technologically quantified through three different

The Blackfoot are a tribe of Native Americans who currently live in Montana and Alberta. They lived northwest of the Great Lakes and came to participate in Plains Indian culture. In Blackfoot mythology, the supernatural world is dominated by the Sun. The Sun or the Creator (Nah-too-si; Super powered or Holiness) is believed to have created the earth and everything in the universe. Nah-too-si is sometimes personified by the mystical Napi, or Old Man. Napi was said to have been sent by the Nah-too-si to teach people how to live a sinless life, like He and his wife, Ksah-koom-aukie, Earth Woman. Napi is said to have given the Blackfoot visions and, by implication, Blackfoot music. The numbers four and seven, the cardinal directions, the six principle points and center, are important in Blackfoot mythology. Communication is believed to occur between the supernatural world and Blackfoot through visions of guardian spirits, during which songs and ceremonies may be imparted, such as that of medicine ...

The authors estimated the global burden of disease for bladder, lung, and skin cancers attributable to inorganic arsenic in food. The authors - 1) established dose response estimates by converting dose response estimates for water exposure to human dose; 2) estimated exposure using data on a common range of arsenic content for food crops grown in different parts of the world and dietary patterns in different parts of the world; 3) multiplied the dose-response slope factor with the estimated range of daily dietary inorganic arsenic exposure to characterize cancer risk; and 4) summed across different populations to estimate the global burden of a particular arsenic-induced cancer ...
5.1 Exposure data. Exposure of high levels of arsenic in drinking-water has been recognized for many decades in some regions of the world, notably in China, Taiwan (China) and some countries in Central and South America. More recently, it has been discovered that a number of other regions have drinking-water that is highly contaminated with arsenic. In most of these regions, the drinking-water source is groundwater, naturally contaminated from arsenic-rich geological formations. The primary regions where high concentrations of arsenic have been measured in drinking-water include large areas of Bangladesh, China and West Bengal (India) and smaller areas of Argentina, Australia, Chile, Mexico, Taiwan (China), the USA and Viet Nam. In some areas of Japan, Mexico, Thailand and other countries, mining, smelting and other industrial activities have contributed to elevated concentrations of arsenic in local water sources.. Levels of arsenic in affected areas may range from tens to hundreds or even ...
Exposure to arsenic, a common environmental toxin found in drinking water, leads to a host of neurological pathologies. We have previously demonstrated that developmental exposure to a low level of arsenic (50ppb) alters epigenetic processes that underlie deficits in adult hippocampal neurogenesis leading to aberrant behavior. It is unclear if arsenic impacts the programming and regulation of embryonic neurogenesis during development when exposure occurs. The master negative regulator of neural-lineage, REST/NRSF, controls the precise timing of fate specification and differentiation of neural stem cells (NSCs). Early in development (embryonic day 14), we observed increased expression of Rest, its co-repressor, CoREST, and the inhibitory RNA binding/splicing protein, Ptbp1, and altered expression of mRNA spliced isoforms of Pbx1 that are directly regulated by these factors in the male brain in response to prenatal 50ppb arsenic exposure. These increases were concurrent with decreased expression of
The result of this study demonstrates a dose-response relationship between inorganic arsenic exposure from drinking water and risk of hypertension. Despite the lack of previous individual exposure data and the lack of information on potential confounders other than those we controlled for, the association seems strong enough to support the possibility of a causal association. There is also good agreement with the observations from Taiwan.8 Although there was no comprehensive, systematic sampling of the water supplies of the study area, the existing water measurements permit a reasonably good assessment of arsenic exposure. Furthermore, the effect of various unknown factors, such as use of bottled water, would dilute the effect and lead to an underestimation of the association. Because our study subjects were recruited from villages in which residents had similar occupations, socioeconomic status, lifestyles, and dietary habits, including salt intake, the variation among subjects of these ...
In January 2016, the EU imposed a maximum limit of inorganic arsenic on manufacturers in a bid to mitigate associated health risks. Researchers at the Institute for Global Food Security at Queens have found that little has changed since this law was passed and that 50 percent of baby rice food products still contain an illegal level of inorganic arsenic.. This research has shown direct evidence that babies are exposed to illegal levels of arsenic despite the EU regulation to specifically address this health challenge. Babies are particularly vulnerable to the damaging effects of arsenic that can prevent the healthy development of a babys growth, IQ and immune system to name but a few, said Andy Meharg, lead author of the study and professor of plant and soil sciences at Queens.. Rice has, typically, 10 times more inorganic arsenic than other foods and chronic exposure can cause a range of health problems including developmental problems, heart disease, diabetes and nervous system ...
From our show, youve heard about high arsenic levels in apple juice. Now, a new report sheds light on arsenic levels in another food: rice.
About Arsenic== Arsenic is the 33rd element which symbol is As in the periodic table and is a chemical element found in many mineral or in pure crystal forms. ,br> It is or was used in many industrial sectors as chemistry, electronics, metalworking, military, pharmaceutical, phytosanitary, mining, and others. ,br> Arsenic is also found in ground water, soil, air due to industrial or geological pollution and is found in many different forms and is often conjugated with sulfur and others metal.,br> Almost all arsenic products are toxic but the inorganic ones are more dangerous. The AsO3, also called arsenic trioxide or arsenite, is one of the most common form in the environment because of its important production in industry (around 50000 tones per year). Its also a soluble form which thus can be ingested by drinking water which contain some. It explains why its one of the most toxic form (until 500 times more toxic than pure arsenic). ,br>,br> Acute intoxication is caused by ingestion of a ...
Protection against arsenic damage in organisms positioned deep in the tree of life points to early evolutionary sensitization. Here, marine sedimentary records reveal a Proterozoic arsenic concentration patterned to glacial-interglacial ages. The low glacial and high interglacial sedimentary arsenic concentrations, suggest deteriorating habitable marine conditions may have coincided with atmospheric oxygen decline after ~2.1 billion years ago. A similar intensification of near continental margin sedimentary arsenic levels after the Cryogenian glaciations is also associated with amplified continental weathering. However, interpreted atmospheric oxygen increase at this time, suggests that the marine biosphere had widely adapted to the reorganization of global marine elemental cycles by glaciations. Such a glacially induced biogeochemical bridge would have produced physiologically robust communities that enabled increased oxygenation of the ocean-atmosphere system and the radiation of the complex ...

Arsenic exposure is a major public health problem in Bangladesh, where nearly 77 million people have been chronically exposed to arsenic through the consumption of naturally contaminated groundwater. Dietary factors influencing the metabolism of ingested arsenic may potentially be important modifiers of the health effects of arsenic in this ...
In 2013 FSANZ released a survey on the levels of inorganic arsenic in a range of seaweed types and products containing seaweed, available in Australia.. The levels in most seaweed tested were below the regulatory limit for inorganic arsenic, with the exception of one hijiki seaweed sample. Because this sample was made up of two individual samples of the same brand of hijiki it may not be representative of all hijiki seaweed available for sale in Australia. Hijiki seaweed is also tested at the border for inorganic arsenic and compliance rates are high.. The New Zealand Ministry for Primary Industries (MPI) has also conducted tests on levels of arsenic in imported hijiki products and found some levels exceeding the regulatory limit for inorganic arsenic.. Using the information collected on the levels of inorganic arsenic in seaweed, dietary exposure to inorganic arsenic was estimated for the Australian population. Using the median inorganic arsenic concentrations in seaweed, the contribution of ...
What is arsenic and where do you find it?. Arsenic is a naturally occurring element that is widely distributed in the earths crust. Arsenic can exist in several oxidation states with other elements as inorganic or organic arsenic. It is a silvery-gray, semimetallic substance that tarnishes in air. Inorganic and organic arsenic compounds are white in color, and have no smell or special taste. Inorganic arsenic occurs naturally in certain types of soils and rock formations. Inorganic arsenic compounds are mainly used as a preservative in pressure-treated wood to make it resistant to rotting and decay. Organic arsenic compounds are used to make insect killers, weed killers, and fungicides.. Who is exposed to arsenic?. Anyone can be exposed to arsenic since low levels of arsenic are present in soil, water, food, and air. People are primarily exposed to arsenic through eating food (fish and shellfish), drinking water, or breathing air containing arsenic. If wells are drilled in areas where naturally ...
Exposure to arsenic has been linked to a variety of adverse human health effects, including skin lesions; skin, lung, and bladder cancer; vascular diseases; low birth weight; and potentially diabetes mellitus and increased susceptibility to infection [1-3]. Although human exposure to the more toxic, inorganic forms of arsenic is thought to occur primarily through drinking water [3, 4], elevated concentrations of arsenic in certain foods may pose an additional risk to consumers (e.g., [2]). Foods with particularly high total arsenic concentrations include fish and seafood [5-9]; cereals and cereal products, particularly rice and rice-based products [5-7, 10, 11]; and bran and germ [2]. Using diet data and physiological models to estimate total arsenic exposure, Xue et al. [12] found that fruits and fruit juices, vegetables, and beer and wine also can be important sources of dietary arsenic; more recent studies document high arsenic concentrations in cruciferous vegetables in particular [13]. ...
The German Federal Institute for Risk Assessment (BfR) is recommending that methods to minimise the levels of inorganic arsenic in rice products should be investigated in the light of recent dietary exposure studies in the German population.. Analyses of rice and rice products in Germany have shown that many contain relatively high concentrations of carcinogenic inorganic arsenic. Some products, such as rice cakes, were found to contain more inorganic arsenic than rice grains, but the reason for this is not known.. The BfR has calculated the intake of toxic inorganic arsenic compounds through the consumption of rice and rice products in Germany and concludes that they could make a significant contribution to the overall intake, especially in children. Because inorganic arsenic compounds are classified as carcinogenic for humans, foodstuffs should only contain as little as reasonably achievable, says BfR President Professor Dr Dr Andreas Hensel.. The Institute is advising food manufacturers to ...
Posted on Jul 7, 2013 , 1 comment. By The Editors Despite the high toxicity of arsenic, there are arsenical drugs - in other words, there are drugs that contain arsenic. One of these drugs, roxarsone, is used in chicken feeds to kill intestinal parasites, promote growth (make the chicken grow faster) and improve pigmentation (make meat look pinker). Roxarsone contains organic arsenic, which is much less toxic than inorganic arsenic. However, mounting evidence suggests organic arsenic can change into inorganic arsenic once administered to chickens. The U.S. Environmental Protection Agency (EPA) classifies inorganic arsenic as a known human carcinogen - This classification is based on extensive population studies of lung cancers that developed following arsenic exposure through inhalation, and skin cancers that developed following ingestion of contaminated drinking water in adults. According to the EPA, arsenic exposure also may be associated with a higher incidence of bladder, liver, kidney, and ...
Silver Spring, MD (TFC) - An approved animal drug known as 3-Nitro® (roxarsone) was added to chicken feed prior to July 2011. This drug was known to contain an organic form of arsenic, which is known to be toxic, but indeed it is less toxic than inorganic arsenic. In 2011, the Food and Drug Administration admitted that roxarsone contained inorganic arsenic, which is a much more toxic compound. After discovering this, the FDAs Center for Veterinary Medicine and the Center for Food Safety and Applied Nutrition developed a new analytical method used to detect minute levels of arsenic in animal tissue.. It is important to note that organic arsenic is in the environment as a naturally occurring substance and can also be a contaminant in water, air, soil and various food products. In this case, the cause for concern is the organic arsenic found in 3-Nitro® that could transform into inorganic arsenic found in the chicken feed at high levels.. The FDA made a statement in the Product Safety ...
Arsenic concentrations in domestic well-water throughout large regions of Minnesota exceed the public drinking-water standard set by the U.S. Environmental Protection Agency. The frequency of arsenic contamination in domestic wells is a serious and widespread public-health concern; long-term exposure to arsenic is toxic to humans, even at extremely low concentrations. Although the Minnesota well code now requires that each new potable water-supply well be tested for arsenic, the information can come only after the well has been drilled. Although homeowners can purchase arsenic-removal systems, they are expensive, require maintenance, and do not provide alarms for high arsenic concentrations or system failure. It would be preferable if wells could be placed where the risk of arsenic contamination of groundwater is known to be low. This article summarizes the authors collaboration with the U.S. Geological Survey, the Minnesota Geological Survey, and the Minnesota Department of Natural Resources to ...
Beyond Pesticides, September 20, 2012) Raising questions about the adequacy of pesticide regulation, historically and ongoing, Consumer Reports published a new study yesterday that finds worrisome levels of inorganic arsenic in rice products. Arsenic is a known human carcinogen. This new report follows its earlier one that finds high levels of arsenic in apple and grape juice. The report finds elevated arsenic levels across organic and conventional products, raising serious questions about widespread environmental and soil contamination from past and continuing arsenical pesticide use. Although organic arsenic occurs naturally in the environment, it is synthetic inorganic arsenic that poses the biggest health hazards to humans and animals. So, humans are exposed to two kinds of the carcinogen in air, water, soil, and food sources. But unlike organic arsenic, which is found naturally in the environment, inorganic arsenic is present in our food as a result of pesticide application and animal ...
Studies into arsenic in food have been restricted by a lack of speciation data. Of more than 100,000 arsenic concentrations submitted to EFSA for evaluation, some 98% were reported as total arsenic but only a few broke figures down into organic and inorganic. European authorities have adopted EFSAs 2009 report and maximum limits for inorganic arsenic are planned to be introduced for rice and rice-based infant food. The introduction of maximum limits for cereals, algae and food supplements is also under discussion.. In the US the Food and Drug Administration has been measuring total arsenic concentrations in food products since 1991, but has yet to establish a specific standard. A guideline for arsenic (total) in crustacean and molluscs of 76ppm and 86 ppm respectively, was introduced in 1993, but it is currently examining the risks associated with longterm exposure.. CODEX has a standard for total arsenic in various foods (fats, margarine, olive oil, vegetable oil, mineral water and salt), but ...
In mammals, methylation occurs in the liver by methyltransferases, the products being the (CH3)2AsOH (dimethylarsinous acid) and (CH3)2As(O)OH (dimethylarsinic acid), which have the oxidation states As(III) and As(V), respectively.[2] Although the mechanism of methylation of arsenic in humans has not been elucidated, the source of methyl is methionine, which suggests a role of S-adenosyl methionine.[25] Exposure to toxic doses begin when the livers methylation capacity is exceeded or inhibited. There are two major forms of arsenic that can enter the body, arsenic (III) and arsenic (V).[26] Arsenic (III) enters the cells though aquaporins 7 and 9, which is a type of aquaglyceroporin.[26] Arsenic (V) compounds use phosphate transporters to enter cells.[26] The arsenic (V) can be converted to arsenic (III) by the enzyme purine nucleoside phosphorylase.[26] This is classified as a bioactivation step, as although arsenic (III) is more toxic, it is more readily methylated.[27]. There are two routes ...
Digging of tube wells to provide drinking water in Bangladesh has had the side-effect of exposing people to arsenic which contaminates groundwater in the country. This project investigates (i) how arsenic concentrations that result from the ingestion of arsenic affect the capabilities and productivity of the rural Bangladesh population and (ii) how changes in food consumption, by affecting arsenic ingestion and excretion, affect arsenic concentrations. ...
Background|br /|Arsenic is present in numerous ecosystems and microorganisms have developed various mechanisms to live in such hostile environments. Herminiimonas arsenicoxydans, a bacterium isolated from arsenic contaminated sludge, has acquired remarkable capabilities to cope with arsenic. In particular our previous studies have suggested the existence of a temporal induction of arsenite oxidase, a key enzyme in arsenic metabolism, in the presence of As(III).|br /|Results|br /|Microarrays were designed to compare gene transcription profiles under a temporal As(III) exposure. Transcriptome kinetic analysis demonstrated the existence of two phases in arsenic response. The expression of approximatively 14% of the whole genome was significantly affected by an As(III) early stress and 4% by an As(III) late exposure. The early response was characterized by arsenic resistance, oxidative stress, chaperone synthesis and sulfur metabolism. The late response was characterized by arsenic metabolism and associated
It is reported by the wall street journal that in the recent study conducted it is found that 100 broiler chickens have inorganic arsenic at huge levels in the livers. These chickens were treated with 3-Nitro of Pfizer. Thus, the sale and of 3-Nitro was stopped in July and another treatment was suggested for the chickens.. The products with high arsenic were called back from all the stores in US and FDA assets that the chicken consists of arsenic at the safer level and is not dangerous for health anymore.. The production industry of meat wants to hide the truth about the adverse impact of arsenic on the human health. The combination of arsenic, lead and mercury are highly toxic effect on children and fetuses. This fact is backed by the study conducted by the University of South Carolina Department of Environmental Health Services.. The toxic level of arsenic is very high and considered as 4 times more toxic than mercury. The Journal of the American Medical Association has published a study which ...
Water supplies in many parts of the world contain naturally occurring arsenic. Previous studies have shown that arsenic at high doses can cause cancer of the bladder. The risk at lower doses is unknown. This study is examining the relationship between ingested arsenic and bladder cancer in central Nevada and Kings County, California, two areas where a large percentage of the population was exposed to drinking water containing arsenic at low to moderate levels. Approximately 200 people with bladder cancer and 400 people without bladder cancer will be included. Subjects are interviewed by telephone about past residences, occupations, diet, drinking water consumption, and other lifestyle factors. Arsenic measurements in well water have been collected from the appropriate state agencies and are being matched with residences and drinking water consumption rates to estimate lifetime arsenic exposures for each subject. People with bladder cancer will then be compared to those without to see if people ...
The World Health Organization (WHO) calls it the biggest mass poisoning of a population in history. There are millions of Bangladeshis exposed to poisonous arsenic from drinking water. Even rice and other crops irrigated with toxic water are in question. The rise of cancer, ulcers, gangrene, and painful warts are reported from various corners of Bangladesh those are directly linked to arsenic poisoning. WHO says that within the next decade one-tenth of all deaths in southern Bangladesh will be due to this arsenic crisis. That is about 20,000 deaths per year. Will anyone be held responsible for this? Arsenic, Microbes and Tragedy of Turtle Pace Scientists observe that the arsenic poisoning in water is a natural phenomenon. Many of them believe that arsenic has been eroded naturally from the Himalayas by the Ganges over thousands of years and deposited amid silt in the rivers delta region. [1] Many believe that arsenic used to be attached with the silt on iron hydroxide particles. And now, ...
Groundwater in California is very precious, yet what we can withdraw is often contaminated with natural and anthropogenic pollution sources. We have examined the Borrego Valley (BV) groundwater (N = 6 wells) in southern California to understand the source of arsenic and nitrate in some of its groundwater production wells. The results show that the arsenic values range from
Arsenic metabolism, but not iAs exposure, was prospectively associated with diabetes incidence in American Indians from Arizona, Oklahoma, and North and South Dakota. Higher iAs% and DMA% in urine, due to lower MMA%, was associated with higher diabetes incidence. Consistently, higher MMA% was associated with lower risk of diabetes. The associations persisted after adjustment for sociodemographic factors, smoking, alcohol, kidney function, and measures of adiposity. These novel findings support that arsenic metabolism patterns, in particular lower MMA%, may be a predisposing factor for diabetes. Arsenic exposure, measured by the concentration of inorganic plus methylated arsenic species in urine, however, was not associated with diabetes incidence in this study population. The study was conducted in a population with a high burden of obesity and diabetes (49) and characterized by low to moderate arsenic exposure levels.. Nongenetic determinants of arsenic metabolism include sex (women have higher ...
Levels of arsenic in baby rice cereal are much higher than other infant cereals, according to a recent study.. And, some are higher than FDA recommendations.. Healthy Babies Bright Futures, an advocacy group working to reduce toxins in a babys environment, tested 105 cereals nationwide for arsenic contamination. The group found arsenic levels in infant rice cereal averaged six times higher than in oatmeal, multi-grain, quinoa and other non-rice infant cereals, in a non-peer reviewed study published online this week.. The group is calling on the U.S. Food and Drug Administration to more strictly regulate arsenic levels in baby food. The toxin is associated with developmental defects, cardiovascular disease, neurotoxicity, diabetes and even cancer, according to the World Health Organization.. In 2016, the FDA proposed a recommendation of no more than 100 parts per billion of arsenic in infant cereal. That recommendation isnt requirement. (To put that in perspective, the Environmental Protection ...
Quilicura is a municipality located in the Santiago Metropolitan Region in Chile. Well #3 has a flow of 1600 gallons per minute (100 liters per second). The well has a high concentration of arsenic that fluctuates between 0.040 mg/L and 0.060 mg/L, well above the World Health Organization standard of 0.010 mg/L. In addition to the high arsenic concentration, the site has challenges with pH that ranges from 7.0 to 9.5. AdEdge was contacted by EcoRiles in 2013 to design, manufacture, and commission an arsenic removal solution for the Quilicura municipalty.The AdEdge arsenic treatment solution consists of four WaterPOD containerized systems rated for a combined total of 1600 gpm (100 lps). Each WaterPOD contains six 48-inch carbon steel vessels in a parallel configuration. The vessels are loaded with AdEdge Bayoxide E33 granular ferric oxide media. The E33 binds the arsenic to the media structure and does not lose that bond during backwash. The system has an ADIN chemical feed dosing system that is ...
Arsenic and fluoride are major contaminants of drinking water. Mechanisms of toxicity following individual exposure to arsenic or fluoride are well known. However, it is not explicit how combined exposure to arsenic and fluoride leads to cellular and/or DNA damage. The present study was planned to assess (i) oxidative stress during combined chronic exposure to arsenic and fluoride in drinking water, (ii) correlation of oxidative stress with cellular and DNA damage and (iii) mechanism of cellular damage using IR spectroscopy. Mice were exposed to arsenic and fluoride (50 ppm) either individually or in combination for 28 weeks. Arsenic or fluoride exposure individually led to a significant increase in reactive oxygen species (ROS) generation and associated oxidative stress in blood, liver and brain. Individual exposure to the two toxicants showed significant depletion of blood glutathione (GSH) and glucose 6-phosphate dehydrogenase (G6PD) activity, and single-stranded DNA damage using a comet ...
According to Foods Matter in their article Rice and Arsenic - what is going on?, some countries and locations have higher arsenic levels than others. Heres where I have to eat crow. As an known opponent to Chinese Food it appears that China has actually set into place a plan to limit the arsenic levels in rice, probably because of their higher consumption of rice in general. The above article states that the safest places to obtain your rice from are: Indian, Pakistani, Nepalese, Chinese, Egyptian, Thai and the worst places: American, European (esp. Italian & French), Bangladeshi. The American delima seems to be that we often grow rice on former Cotton fields where the source of arsenic in the soil seems to be the pesticides used on the former cotton crop. One option offered, with the second article in the above article series, was to suggest breeding a rice that did not take up as much arsenic. WOW, isnt messing with Gods created product and the possible reason many today cant eat wheat? ...

Arsenic has been found in at least 781 of 1,300 National Priorities List sites (hazardous waste sites) identified by the U.S. Environmental Protection Agency. A release from an industrial plant, or from a container, does not always lead to exposure. You can be exposed to a chemical only when you come into contact with it. Exposures occur through breathing, eating, or drinking substances containing the chemical, or from skin contact with it. If you are exposed to arsenic, the appearance of symptoms and their seriousness is dependent upon how much, how long and by what way you were exposed. Your sex, age, lifestyle and state of health also contribute. What is arsenic?. Arsenic is a naturally occurring gray metal-like material found in the environment combined with other elements. Most of these combined compounds are white or colorless powders that do not evaporate. They have no smell, and most have no special taste, so you cannot tell if arsenic is present in your food, water, or air. Arsenic is ...

1. Total arsenic The method described in this manual assesses arsenic exposure by analyzing urine through the use of inductively coupled-plasma dynamic reaction cell-mass spectrometry (ICP-DRC-MS). Urine is analyzed because urinary excretion is the major pathway for eliminating arsenic from the mammalian body. This method achieves rapid and accurate quantification of total urinary arsenic. Total urine arsenic concentrations are determined by using ICP-DRC- MS. This multielement analytical technique is based on quadrupole ICP-MS technology and includes DRC™ technology, which minimizes or eliminates much argon-based polyatomic interference. Coupling radio frequency power into a flowing argon stream seeded with electrons creates the plasma, the heat source, which is ionized gas suspended in a magnetic field. Predominant species in the plasma are positive argon ions and electrons. Diluted urine samples are converted into an aerosol by using a nebulizer inserted within a spray chamber. A portion of ...

Landfills have the potential to mobilize arsenic via induction of reducing conditions in groundwater and subsequent desorption from or dissolution of arsenic-bearing iron phases. Laboratory incubation experiments were conducted with materials from a landfill where such processes are occurring. These experiments explored the potential for induced sulfate reduction to immobilize dissolved arsenic in situ. The native microbial community at this site reduced sulfate in the presence of added acetate. Acetate respiration and sulfate reduction were observed concurrent with dissolved iron concentrations initially increasing from 0.6 mu M (0.03 mg L-1) to a maximum of 111 mu M (6.1 mg L-1) and subsequently decreasing to 0.74 mu M (0.04 mg L-1). Dissolved arsenic concentrations initially covaried with iron but subsequently increased again as sulfide accumulated, consistent with the formation of soluble thioarsenite complexes. Dissolved arsenic concentrations subsequently decreased again from a maximum of ...
The Associated Press has announced that the FDA at long last gave prove that the chickens that got the medication were really positive for inorganic arsenic on tests.. Despite the fact that this has been overlooked for quite a while, the FDA has at last chosen to report that the chicken meat we as a whole purchase from the stores in the U.S. contains arsenic, which is a to a great degree lethal compound which prompts to different medical problems, malignancy, and even demise.. However, the most irritating certainty is that the arsenic is quite placed in chicken.. In particular, in 2006, the IATPs report Playing Chicken: Avoiding Arsenic inside the meat you eat, demonstrated that even 70 percent of the chickens in the U.S are nourished with arsenic keeping in mind the end goal to help the weight pick up and to get the ordinary sound shading on account of pigs, chickens, and turkeys.. The FDA found that half of all chickens have assimilated this poison inside the liver.. The organization even ...
A Stuckey et al. (2015) paper looked into the release of arsenic from sediments in the Mekong Delta in Vietnam. The researchers looked at the quality of carbon and its effect on arsenic release in the sediment profile. They also studied reactions in both seasonally saturated wetlands-inundated only through part of the year-and in permanent wetlands. In these wetlands, arsenic was released by bacteria consuming it for respiration in the absence of oxygen, using carbon as fuel. The source of carbon powering the microbes is organic matter on the earths surface.. In this study, the only place where arsenic was released naturally was in the near surface sediments of permanent wetlands. This is because of the carbon on the surface as well as the amount of oxygen available for degradation. In seasonally saturated wetlands arsenic is not released because organic matter has been consumed in aerobic (oxygenated) processes and there is nothing left for the bacteria to eat. However, in permanently ...
Groundwater in Eastern Croatia contains elevated concentrations of inorganic arsenic. The biggest well field in the area has an average arsenic concentration of 200 μg/L and it supplies the population of around 200,000 people with drinking water. Croatian Regulation has adopted guidelines from the European Council Directive for the maximum concentration limit (MCL) of 10 μg/L of As in drinking water. However, it has been estimated that almost 120,000 people drink water from that well field with a concentration of arsenic over 10 μg/L. To reduce the health risks associated with arseniccontaminated water intake in Eastern Croatia it is important to develop proper strategies that will use one of the following technologies for arsenic removal: oxidation, coagulation-flocculation, adsorption, ion exchange or membrane technologies ...
Dr. Linda Smith The goal is to reduce a major health threat to perhaps millions of people in Nepal alone - and possibly many more in surrounding South Asian countries. During her first trip to Southern Nepal in 2001 to conduct research on the arsenic contamination phenomenon, Smith said, she found villages where numerous people were suffering from arsenic poisoning and nothing was being done to help them. Samples of the water drawn from shallow wells, she said, nearly all showed contamination, some at astoundingly high levels - as much as 650 parts per billion (ppb) versus the 10 ppb level considered safe in the United States. Those drinking such water often exhibit signs of poisoning, including blackened palms due to the death of nerves and skin that sloughs off the soles of feet. Arsenic poisoning, or arsenicosis, is also thought to lead to cancer, gangrene and other serious health complications, including death, Smith said. The problem is the shallow wells, consisting of iron pipes driven ...
Arsenic contamination is one of the major problems that affects millions of people across the world. Our water, food, soil, air - everything can be contaminated by arsenic. In India, arsenic contamination is high in groundwater that affects over 50 million people in different states of the country. Consuming contaminated food or water for a long time can cause severe diseases. However, installing deep wells can solve the problem as it ensure purified water.. ...
The Bangladeshi government has failed to adequately respond to the problem of arsenic contamination in rural drinking water sources, according to a report released on April 6th by international rights watchdog Human Rights Watch.
In June 2011, AdEdge Water Technologies was contacted by Sunrise Engineering to design, manufacture, and start up an arsenic removal system for the Spring Creek Utilities Company located in Elko, Nevada. The existing water system consisted of three wells feeding into a centralized distribution system with a maximum capacity of 1950 GPM and serves a population of 1500 residents. The AdEdge treatment system consists of five WaterPOD containerized units each housing an ADGS+ coagulation/filtration arsenic removal system. All five WaterPODs are integrated with an existing chlorine module to oxidize arsenic (III) to arsenic (V) for optimal removal. The units also integrate with an AdEdge ADIN chemical feed module which injects ferric chloride in the raw water to supplement the iron concentration to aid in arsenic removal. A CO2 pH adjustment module is furnished in each WaterPOD to reduce the pH from 7.89 to a neutral pH of 7. AdEdge also provided an H2Zero backwash recycle system that reclaims 100% ...
When in contact with active metals such as arsenic, iron, aluminum, zinc, or when heated to decomposition, it emits highly toxic fumes of arsenic. Upon contact with water hydrogen chloride is produced. Water causes it to decompose to yield arsenic acid and hydrochloric acid. Avoid active metals such as arsenic, iron, aluminum, zinc, decomposed by water to form arsenic hydroxide and hydrogen chloride. Avoid air, ultraviolet light. Hazardous polymerization may not occur ...
The saga of arsenic life appears to be finally coming to a close. Two papers out in Science this week put under the microscope the claim that the bacterium could incorporate arsenic into its DNA in place of phosphorus. And the two teams found no evidence that the bacteria could make use of arsenic.. When the arsenic life story kicked off back in December 2010, it was big news. (You can read our coverage of it here, here and here.) The discovery by a Nasa team led by Felisa Wolfe-Simon that a bacterium could make use of an exotic element not normally used by life cracked open the door an inch to the idea that there could be life on more planets than ever thought possible. After all, if we could find bacteria thriving in the arsenic laced lakes of California, then surely they could be eking out a living on inhospitable planets.. However, some researchers were less than impressed with the science and they took to social media channels to register their concerns with the paper, with Nasa and with ...
