Overexpression of the multidrug resistance-associated protein (MRP1) in human heavy metal-selected tumor cells. (1/915)

Cellular and molecular mechanisms involved in the resistance to cytotoxic heavy metals remain largely to be characterized in mammalian cells. To this end, we have analyzed a metal-resistant variant of the human lung cancer GLC4 cell line that we have selected by a step-wise procedure in potassium antimony tartrate. Antimony-selected cells, termed GLC4/Sb30 cells, poorly accumulated antimony through an enhanced cellular efflux of metal, thus suggesting up-regulation of a membrane export system in these cells. Indeed, GLC4/Sb30 cells were found to display a functional overexpression of the multidrug resistance-associated protein MRP1, a drug export pump, as demonstrated by Western blotting, reverse transcriptase-polymerase chain reaction and calcein accumulation assays. Moreover, MK571, a potent inhibitor of MRP1 activity, was found to markedly down-modulate resistance of GLC4/Sb30 cells to antimony and to decrease cellular export of the metal. Taken together, our data support the conclusion that overexpression of functional MRP1 likely represents one major mechanism by which human cells can escape the cytotoxic effects of heavy metals.  (+info)

Enhanced bioaccumulation of heavy metal ions by bacterial cells due to surface display of short metal binding peptides. (2/915)

Metal binding peptides of sequences Gly-His-His-Pro-His-Gly (named HP) and Gly-Cys-Gly-Cys-Pro-Cys-Gly-Cys-Gly (named CP) were genetically engineered into LamB protein and expressed in Escherichia coli. The Cd2+-to-HP and Cd2+-to-CP stoichiometries of peptides were 1:1 and 3:1, respectively. Hybrid LamB proteins were found to be properly folded in the outer membrane of E. coli. Isolated cell envelopes of E. coli bearing newly added metal binding peptides showed an up to 1.8-fold increase in Cd2+ binding capacity. The bioaccumulation of Cd2+, Cu2+, and Zn2+ by E. coli was evaluated. Surface display of CP multiplied the ability of E. coli to bind Cd2+ from growth medium fourfold. Display of HP peptide did not contribute to an increase in the accumulation of Cu2+ and Zn2+. However, Cu2+ ceased contribution of HP for Cd2+ accumulation, probably due to the strong binding of Cu2+ to HP. Thus, considering the cooperation of cell structures with inserted peptides, the relative affinities of metal binding peptide and, for example, the cell wall to metal ion should be taken into account in the rational design of peptide sequences possessing specificity for a particular metal.  (+info)

High concentrations of heavy metals in neighborhoods near ore smelters in northern Mexico. (3/915)

In developing countries, rapid industrialization without environmental controls has resulted in heavy metal contamination of communities. We hypothesized that residential neighborhoods located near ore industries in three northern Mexican cities would be heavily polluted with multiple contaminants (arsenic, cadmium, and lead) and that these sites would be point sources for the heavy metals. To evaluate these hypotheses, we obtained samples of roadside surface dust from residential neighborhoods within 2 m of metal smelters [Torreon (n = 19)] and Chihuahua (n = 19)] and a metal refinery [Monterrey (n = 23)]. Heavy metal concentrations in dust were mapped with respect to distance from the industrial sites. Correlation between dust metal concentration and distance was estimated with least-squares regression using log-transformed data. Median dust arsenic, cadmium, and lead concentrations were 32, 10, and 277 microg/g, respectively, in Chihuahua; 42, 2, and 467 microg/g, respectively, in Monterrey, and 113, 112, and 2,448 microg/g, respectively, in Torreon. Dust concentrations of all heavy metals were significantly higher around the active smelter in Torreon, where more than 90% of samples exceeded Superfund cleanup goals. At all sites, dust concentrations were inversely related to distance from the industrial source, implicating these industries as the likely source of the contamination. We concluded that residential neighborhoods around metal smelting and refining sites in these three cities are contaminated by heavy metals at concentrations likely to pose a health threat to people living nearby. Evaluations of human exposure near these sites should be conducted. Because multiple heavy metal pollutants may exist near smelter sites, researchers should avoid attributing toxicity to one heavy metal unless others have been measured and shown not to coexist.  (+info)

Transcriptional organization of the czc heavy-metal homeostasis determinant from Alcaligenes eutrophus. (4/915)

The Czc system of Alcaligenes eutrophus mediates resistance to cobalt, zinc, and cadmium through ion efflux catalyzed by the CzcCB2A cation-proton antiporter. DNA sequencing of the region upstream of the czcNICBADRS determinant located on megaplasmid pMOL30 revealed the 5' end of czcN and a gene for a MgtC-like protein which is transcribed in the orientation opposite that of czc. Additional open reading frames upstream of czc had no homologs in the current databases. Using oligonucleotide-probed Northern blotting experiments, a 500-nucleotide czcN message and a 400-nucleotide czcI message were found, and the presence of 6, 200-nucleotide czcCBA message (D. Van der Lelie et al., Mol. Microbiol. 23:493-503, 1997) was confirmed. Induction of czcN, czcI, czcCBA, and czcDRS followed a similar pattern: transcription was induced best by 300 microM zinc, less by 300 microM cobalt, and only slightly by 300 microM cadmium. Reverse transcription-PCR gave evidence for additional continuous transcription from czcN to czcC and from czcD to czcS, but not between czcA and czcD nor between czcS and a 131-amino-acid open reading frame following czcS. The CzcR putative response regulator was purified and shown to bind in the 5' region of czcN. A reporter strain carrying a czcNIC-lacZ-czcBADRS determinant on plasmid pMOL30 was constructed, as were DeltaczcR and DeltaczcS mutants of this strain and of AE128(pMOL30) wild type. Experiments on (i) growth of these strains in liquid culture containing 5 mM Zn2+, (ii) induction of the beta-galactosidase in the reporter strains by zinc, cobalt, and cadmium, and (iii) cDNA analysis of czcCBA mRNA synthesis under inducing and noninducing conditions showed that the CzcRS two-component regulatory system is involved in Czc regulation.  (+info)

Extracellular heavy-metal ions stimulate Ca2+ mobilization in hepatocytes. (5/915)

Populations of hepatocytes in primary culture were loaded with fura 2 and the effects of extracellular heavy-metal ions were examined under conditions that allowed changes in fura 2 fluorescence (R340/360, the ratio of fluorescence recorded at 340 and 360 nm) to be directly attributed to changes in cytosolic free [Ca2+] ([Ca2+]i). In Ca2+-free media, Ni2+ [EC50 (concentration causing 50% stimulation) approximately 24+/-9 microM] caused reversible increases in [Ca2+]i that resulted from mobilization of the same intracellular Ca2+ stores as were released by [Arg8]vasopressin. The effects of Ni2+ were not mimicked by increasing the extracellular [Mg2+], by addition of MnCl2, CoCl2 or CdCl2 or by decreasing the extracellular pH from 7.3 to 6.0; nor were they observed in cultures of smooth muscle, endothelial cells or pituitary cells. CuCl2 (80 microM), ZnCl2 (80 microM) and LaCl3 (5 mM) mimicked the ability of Ni2+ to evoke Ca2+ mobilization. The response to La3+ was sustained even in the absence of extracellular Ca2+, probably because La3+ also inhibited Ca2+ extrusion. Although Ni2+ entered hepatocytes, from the extent to which it quenched fura 2 fluorescence the free cytosolic [Ni2+] ([Ni2+]i) was estimated to be <5 nM at the peak of the maximal Ni2+-evoked Ca2+ signals and there was no correlation between [Ni2+]i and the amplitude of the evoked increases in [Ca2+]i. We conclude that extracellular Ni2+, Zn2+, Cu2+ and La3+, but not all heavy-metal ions, evoke an increase in [Ca2+]i in hepatocytes by stimulating release of the hormone-sensitive intracellular Ca2+ stores and that they may do so by interacting with a specific cell-surface ion receptor. This putative ion receptor may be important in allowing hepatocytes to contribute to regulation of plasma heavy-metal ions and may mediate responses to Zn2+ released into the portal circulation with insulin.  (+info)

Abundance and diversity of Archaea in heavy-metal-contaminated soils. (6/915)

The impact of heavy-metal contamination on archaean communities was studied in soils amended with sewage sludge contaminated with heavy metals to varying extents. Fluorescent in situ hybridization showed a decrease in the percentage of Archaea from 1.3% +/- 0.3% of 4', 6-diamidino-2-phenylindole-stained cells in untreated soil to below the detection limit in soils amended with heavy metals. A comparison of the archaean communities of the different plots by denaturing gradient gel electrophoresis revealed differences in the structure of the archaean communities in soils with increasing heavy-metal contamination. Analysis of cloned 16S ribosomal DNA showed close similarities to a unique and globally distributed lineage of the kingdom Crenarchaeota that is phylogenetically distinct from currently characterized crenarchaeotal species.  (+info)

pABC11 (also known as MOAT-C and MRP5), a member of the ABC family of proteins, has anion transporter activity but does not confer multidrug resistance when overexpressed in human embryonic kidney 293 cells. (7/915)

Several members of the ABC family of proteins have been implicated in multidrug resistance associated with cancer therapies. A novel member of this gene family, designated pABC11, has been identified using degenerate polymerase chain reaction. The full-length cDNA spans 5881 base pairs and encodes an open reading frame of 1437 amino acids predicted to contain two sets of transmembrane domains and two nucleotide binding domains characteristic of ABC proteins. The nucleotide sequence described herein extends that of three recently reported sequences, MRP5 (Kool, M., de Haas, M., Scheffer, G., Scheper, R., van Eijk, M., Juijn, J., Baas, F., and Borst, P. (1997) Cancer Res. 57, 3537-3547), SMRP (Suzuki, T., Nishio, K., Sasaki, H., Kurokawa, H., Saito-Ohara, F., Ikeuchi, T., Tanabe, S., Terada, M., and Saijo, N. (1997) Biochem. Biophys. Res. Commun. 238, 790-794), and MOAT-C (Belinsky, M., Bain, L., Balsara, B., Testa, J., and Kruh, G. (1998) J. Natl. Cancer Inst. 90, 1735-1741), in the 5' direction. Northern blot analysis detected five transcripts that were differentially expressed in several tissue types, and the gene encoding pABC11 was mapped to chromosome 3. Confocal imaging of HEK293 cells expressing a green fluorescent protein-pABC11 construct confirmed plasma membrane localization of the fusion protein. Overexpression of pABC11 resulted in reduced labeling with the fluorochromes 5-chloromethylfluorescein diacetate, fluorescein diacetate, and 2',7'-bis-(2-carboxyethyl)-5 (and-6)-carboxyfluorescein acetoxymethyl ester but not with calcein or rhodamine derivatives, consistent with pABC11 being an anion transporter. Fluorochrome export was ATP-dependent but glutathione-independent. We also show that this export pump does not confer resistance to various classes of cytotoxic drugs but does provide small but significant resistance to CdCl(2) and potassium antimonyl tartrate.  (+info)

Toxicity of copper, cobalt, and nickel salts is dependent on histidine metabolism in the yeast Saccharomyces cerevisiae. (8/915)

The pH-dependent inhibition of 22 metal salts have been systematically investigated for the yeast Saccharomyces cerevisiae. We have established that the inhibition of growth by Cu, Co, or Ni salts is markedly enhanced by histidine auxotrophy and by increasing the pH of the medium. Each of the his1-his7 mutant strains were unable to grow in the presence of elevated levels of Cu, Co, or Ni at nearly neutral pHs, in contrast to His(+) strains, which grew under these conditions. The Cu, Co, or Ni inhibition was reversed by the addition of histidine to the medium. Deletion of the high-affinity histidine permease Hip1p in His(-) strains resulted in even greater sensitivity to Cu, Co, and Ni and the requirement of an even higher level of histidine to reverse the inhibition. These results suggest that intracellular histidine, most likely in the vacuole, diminishes the pH-dependent toxicity of Cu, Co, and Ni. Furthermore, the toxicity of many salts is exacerbated in strains with a defective vacuolar H(+)-ATPase, which abolishes the ability of yeast to maintain an acidic vacuole, a compartment known to sequester metal compounds. We suggest that the accumulation of histidine in the vacuole is a normal process used to detoxify Cu, Co, and Ni.  (+info)

AU - Lu, Min. AU - Hutchinson, Simon M.. AU - Feng, Huan. PY - 2007/5/1. Y1 - 2007/5/1. N2 - In this study, mineral magnetic, particle size and geochemical analyses were conducted on intertidal sediments from the Yangtze Estuary to examine the feasibility of heavy metal concentrations normalization using magnetic techniques. Susceptibility of Anhysteretic Remanent Magnetization (χARM), the ratio of χARM to SIRM (Saturation Isothermal Remanent Magnetization) and susceptibility (χARM/SIRM and χARM/χ, respectively), and to a lesser degree, frequency dependent susceptibility (χfd), displayed significant correlations with the fine sediment fraction (,16 μm). The strong relationships between χARM and heavy metals can be explained by the role of particle size and iron oxides in controlling metal ...
Melatonin (MT), ubiquitous in almost all organisms, functions as a free radical scavenger. Despite several reports on its role as an antioxidant in animals, plants, and some microorganisms, extensive studies in filamentous fungi are limited. Based upon the role of melatonin as an antioxidant, we investigated its role in heavy metal-induced stress tolerance in Exophiala pisciphila, a dark septate endophyte (DSE), by studying the underlying mechanisms in alleviating oxidative stress and reducing heavy metal accumulation. A significant decrease in malondialdehyde (MDA) and oxygen free radical (OFR) in E. pisciphila was recorded under Cd, Zn, and Pb stresses as compared to the control. Pretreatment of E. pisciphila with 200.0 μM exogenous melatonin significantly increased the activity of superoxide dismutase (SOD) under Zn and Pb stresses. Pretreatment with 200.0 μM melatonin also lowered Cd, Zn, and Pb concentrations significantly. Melatonin production was enhanced by Cd, Cu, and Zn after 2 d, and
Pseudomonas aeruginosa is considered as the most potent bacterial strain for solving heavy metals pollution problems. Pollution is the most of problems in our world which causing a lot of risks to human, animal, plant and ecosystem. Heavy metals pollution is an ever-increasing problem in developing nations. Release of heavy metals into the environment has increased in the recent years at an alarming rate. To remove heavy metals from environment, there are different methods such as physical, chemical and biological. The biological method includes microorganisms and plant which recorded high heavy metals removal, safe and low-cost method. Microorganisms remove heavy metals from environment by different mechanisms according to their types. Thus, microbes are used as potential candidates of bioremediation that can adapt quickly to the changing noxious environment and be utilized for toxic metal remediation. In bacterial uptake and tolerance to heavy metals, Pseudomonas aeruginosa recorded potential role in
In order to study heavy metal pollution of the soils and wheat grains alongside the Shanghai-Nanjing Expressway,a survey was carried out with soil samples and wheat samples collected from different sections of the expressway.The results show that the soils within the 250 m wide zones along either side of the expressway and grains of the wheat growing thereupon were polluted with lead to a various extent.The maximum Pb contamination index reached 3.26 in the soil of Suzhou section of the expressway.The pollution of other heavy metals was not significant.According to the national standards for food,the content of Pb in the wheat grains exceeded the standard seriously,while the contents of other heavy metals were lower than the standards.The maximum content of Pb occurred in soils 100 m away from the expressway to either side.While,the maximum content of Pb in wheat grains appeared in places (50-100) m away.It could be concluded that Pb pollution on both sides of highways is still one of the major

Introduction Heavy metals are types of elements naturally present in soil or enter into soil as a result of human activities. The most important route of exposure to heavy metals is daily intake of food. Crops grown in contaminated soil (due to mining activities, industrial operations and agriculture) may contain high concentrations of heavy metals. Also closeness to cities and industrial centers can have a great influence on the accumulation of heavy metals to agricultural products grown in the region. The study aimed to determine the concentration of heavy metals in soil and agricultural products around urban and industrial areas of Zanjan province (North West of Iran) and consumption hazard probability. Materials And Methods Soil (75 samples of soil from a depth of 0 to 10 cm) and plant 101 samples) samples, in the summer 2011, were randomly taken from industrial areas as follow: tomatoes (Lycopersicum esculentum M), wheat seed (Triticum vulgare), barley seeds (Hordeum vulgare), alfalfa shoots
The objective of this study was to assess the effects of heavy metals on microbial decomposition of cellulose in heavy metal-contaminated soils using a cotton strip assay. The assay is a measure of the potential of soil microorganisms to decompose the plant polymer, cellulose. Cellulolytic activity in soil was assessed by determining the reduction in tensile strength of the buried cotton strips over a 25- and 45-day period. Soils were obtained from a rifle range that contain high levels of lead, copper and zinc. The site has been used for approximately 50 years, resulting in metal levels of up to 30,000 mg/kg of lead, 4000 mg/kg of copper and 600 mg/kg of zinc in the most contaminated soils. All the metal-contaminated soils had lower degradation rates than the uncontaminated soils tested. Among the contaminated soils, however, the heavy metal concentration was not the major factor in determining the loss in tensile strength of the cotton strips, where cellulose decomposition was governed by ...
Several plant species are able to accumulate and withstand large quantities of heavy metals in their tissues without dramatic alterations in their growth usually observed in plants. Such metal accumulating plants are tested and used for remediation of contaminated soils and waters. Although the literature provides extensive information on the effect of heavy metals in growth and development of several metal-accumulating and non accumulating plants, nitrogen metabolism and the regulation of related enzymes have not been widely studied. In an effort to better understand the responses of plants species under heavy metal stress, a comparative study was held between two solanaceous species, Nicotiana tabacum and Nicotiana glauca, plants with promising properties for phytoremediation. Plants of the two species were grown in the presence of different concentrations of the heavy metals zinc (Zn), nickel (Ni) and cadmium (Cd) in the following experimental systems in the greenhouse: in pots containing ...

This study was conducted to determine the soil pollution level and ecological risk assessment of different heavy metals in agricultural soils around Nakhlak Pb-Zn mine, located in Anarak district, Nain county of Isfahan province.Methods A total of 50 soil samples were collected from agricultural land around Nakhlak mine and analyzed to determine the concentrations of Pb, Cd, Zn, Ni, Cu, and Mn. The geo-accumulation index (I geo), enrichment factor (EF), and potential ecological-risk index (Er) were used to assess the level of soil pollution with heavy metals.Results The mean concentrations of Pb, Cd, Zn, Ni, Cu, and Mn were 355, 2.72, 347, 26, 36, and 505 mg/kg, respectively, which were higher than the background values of world soils. Based on the Igeo index, the study area was moderately to heavily contaminated with Pb and Zn, uncontaminated to moderate contaminated with Cd and Cu, and
Every aspect of oil and gas operations poses significant negative impacts on the environment in varying levels, these environmental impacts have economic and public health consequences on the indigenes of the operation locality. Produced water discharge is one of such aspects of the upstream oil and gas operation whose potential for environmental degradation has necessitated both local and international regulations for its governance. This research focuses on the environmental assessment of heavy metal pollution on marine sediments receiving treated produced water in Delta state, Nigeria. Sediment samples were obtained from produced water discharge area at various distances from the disposal point. Heavy metals (Cadmium, Zinc, Iron, Lead, Chromium, Vanadium, Barium, Nickel and Manganese) concentrations in the sediment were analyzed using Atomic Absorption Spectrophotometry method. In the sediment, manganese, nickel, chromium, lead, cadmium and zinc were detected in all the locations and showed no
The threat to humans, animals, and plants life by pollution due to gas flare and oil and gas industrial activities cannot be overemphasized. This study compared the hydrocarbons and heavy metals accumulation in cassava tubers harvested from four different locations in Rivers State. The study areas include Rukpoku, Rivers State University (RSU) farm, Eleme community and Nkpolu-Oroworukwo community. Cassava tubers were collected from farms located in the aforementioned areas, prepared and analyzed for hydrocarbons and heavy metals contents. Standard spectro-analytical method was used to determine the concentrations of zinc (Zn), iron (Fe), lead (Pb), copper (Cu) and manganese (Mn), while polycyclic aromatic hydrocarbons (PAHs), total polycyclic hydrocarbon (TPH) and BTEX (benzene, toluene, ethyl benzene, xylene) were analyzed using standard chromatographic procedure. Results obtained from the analyses revealed the presence of heavy metals in all the samples in the order Eleme | Nkpolu-Oroworukwo | Rukpoku
The knowledge about toxic levels of toxic heavy metals in irrigation water is very scarce and quite varied. This work aimed to evaluate the concentrations of toxic heavy metals in the lake of the Experimental Farm UEMG, Passos-MG Unit. The toxic heavy metals evaluated were Cadmium (Cd), Chromium (Cr) and Lead (Pb). The lagoon was divided into ten strategic points for sampling, each point being sampled in triplicate. The pH of the water and the concentrations of toxic heavy metals present were evaluated. PH measurements were performed on the water in natura, being measured before and after filtration. Values ranging from 6.25 to 7.75 were found. For the determinations of Cd, Cr, and Pb, an Atomic Absorption Spectrophotometer was used. The samples were treated with acid digestion. The values of toxic heavy metals found were: Cadmium: 0.727 mg/L at 0.754 mg/L; Chromium: 0.177 mg/L at 0.256 mg/L and Lead: 0.023 mg/L at 0.081 mg/L. These values are above the limit established by CONAMA 357/2005. The dangers
The concentration of heavy metals (Hg, Cd, As, Cu, Pb, Cr, and Zn) in the water, sediment and fish (Mugil cephalus) were investigated from different sites on Köyceğiz Lagoon System. Potential ecological risk analysis of heavy metal concentrations in sediments underlined considerable ecological risk for two sites of the lagoon during winter and spring. The ratio of transfer factors of Hg, Cr, Cu, Zn, and As in fish from water was higher than 1, which means that fish undergo bioaccumulation of these elements from lagoon water. The determination of individual Target Hazard Quotients (THQs) in fish tissue indicated safe levels for the local people, but there is a possible risk in terms of total THQ because the highest THQ value of As suggests that they may experience a certain degree of adverse health effect.

Heavy metals are of public health concern worldwide due to their damaging effects on human and animal health, the environment and life in general. This study assessed concentration levels of some toxic heavy metals: Cadmium (Cd), lead (Pb), copper (Cu) and magnesium (Mg) in blood samples of ten (10) cattle slaughtered in two areas (Jos North and South) of Plateau State, Northern Nigeria. The results were compared with World Health Organization (WHO) standard for heavy metals allowable content in food. The samples were analyzed for Cd, Pb, Cu and Mg in triplicates by Shimadzu Atomic Absorption Spectrophotometer (AA 6800) after wet digestion. The results of the analysis indicated that the levels in parts per million (ppm) range from 0.4169 to 3.0302 for Pb; 0.0067 to 0.0204 for Cd; 0.1112 to 0.9845 for Mg and 0.0027 to 0.0326 for Cu. The mean concentration of Pb was found to be higher than the WHO acceptable limit, while Cd, Cu and Mg were within the WHO acceptable limit. The high value of Pb might be

The concentrations of twenty five heavy metals adsorbed to fine fraction of particulate matter, PM2.5 (d ≤ 2.5 μm) have been experimentally analysed at a sampling site located at the kerbside along a National Highway in Delhi city, India. The sampling has been carried out for 12-hour using Ecotech Intruments, APM550. The PM2.5 has been collected on PTFE filter papers for the winter season. Later, the filter papers have been analysed for various heavy metal concentrations using ED-XRF. It has been observed that the metals concentrations are in this trend: Si > K > S > Ca = Fe > Zn = Pb > Br. it is observed that Si has high co-relation with Ca, Fe and K, which may be due to crustal origin of all three elements; while S, Br and Pb may be from vehicular exhaust emissions and/or abrasions due to brake and tyre wear. The potential health risks associated with different carcinogenic heavy metals have also been calculated. One of the health risk indicators, the excess cancer risk (ECR), is found to be in the

Mercury (Hg) is commonly found in thermometers, batteries, and industrial emissions. Mercury concentrations increase in the food chain, resulting in bioaccumulation that can negatively impact reproduction in humans who consume food, usually tainted seafood. Ultimately, mercury can disrupt spermatogenesis and disrupt fetal development.. Boron (B) is another heavy metal that is used in the manufacturing of glass, cement, soap, carpet, and leather; its effects on the hypothalamic-pituitary axis are comparable to lead. Chronic exposure to heavy metals such as As (arsenic) may also affect sperm quality. Trace amounts of As have been observed in semen which suggests that it may inhibit the function of enzymes present in the acrosome and the membrane which covers the head of the sperm.. While there is not much research on cadmium (Cd), it has been shown experimentally to cause testicular necrosis in mice, as well as marked changes in libido and infertility. Heavy metal toxicity has been associated with ...

Heavy metal contamination in the body plays a major pathological role in many diseases. Small amounts of lead can damage hormones and increase cardiovascular diseases, while mercury can accumulate in the brain leading to memory loss, poor coordination, and hearing or speech impairments among other problems. Aluminum is both neurotoxic and carcinogenic, cadmium causes kidney and respiratory problems, and arsenic may result in headaches, confusion, and night blindness.. Heavy metals are found in food, industrial production, the atmosphere, personal hygiene products, and many other places. The most notable exposure risks for mercury are amalgam tooth fillings and vaccinations containing Thimerosal. Cadmium is emitted from brake dust and endanger workers in various manufacturing processes. Lead is found in paint, food, and other products. Aluminum contamination arises mostly from consuming municipal water and fluoridated water allows aluminum to enter the body more effectively. Aluminum can also ...
Heavy metal (HM) contamination and accumulation is a serious problem around the world due to the toxicity, abundant sources, non-biodegradable properties, and accumulative behaviour of HMs. The degree of soil HM contamination in China, especially in the Yangtze River Delta, is prominent. In this study, 1822 pairs of soil and crop samples at corresponding locations were collected from the southern Yangtze River Delta of China, and the contents of Ni, Cr, Zn, Cd, As, Cu, Hg, and Pb were measured. The single pollution index in soil (SPI) and Nemerow composite pollution index (NCPI) were used to assess the degree of HM pollution in soil, and the crop pollution index (CPI) was used to explore the degree of HM accumulation in crops. The bioaccumulation factor (BAF) was used to investigate the translocation of heavy metals in the soil-crop system. The health risks caused by HMs were calculated based on the model released by the U.S. Environmental Protection Agency. The SPIs of all elements were at the

Heavy metals are naturally occurring elements that have a high atomic weight and a density at least 5 times greater than that of water. Their multiple industrial, domestic, agricultural, medical and technological applications have led to their wide distribution in the environment; raising concerns over their potential effects on human health and the environment. Their toxicity depends on several factors including the dose, route of exposure, and chemical species, as well as the age, gender, genetics, and nutritional status of exposed individuals. Because of their high degree of toxicity, arsenic, cadmium, chromium, lead, and mercury rank among the priority metals that are of public health significance. These metallic elements are considered systemic toxicants that are known to induce multiple organ damage, even at lower levels of exposure. They are also classified as human carcinogens (known or probable) according to the U.S. Environmental Protection Agency, and the International Agency for ...

Concentrations of Al, Fe, Cr, Cu, Ni, Pb and Zn in soils, sediments and water samples collected along the Oued Boufekrane river (Meknes, central Morocco) were determined. In soils, a homogeneous distribution of metal concentrations was observed throughout the study area except for Pb, which presents high enrichment at sites located at the vicinity of a main highway. In sediments, high enrichment, with respect to upstream sites, were observed downstream of the city of Meknes for Al, Cr, Fe and Ni and inside the city for Cu, Zn and Pb. In water samples, the metal contents showed to correlate with their homologues in sediments suggesting that the metal contents in water and sediments have identical origins. Descriptive statistics and multivariate analysis (principal factor method, PFM) were used to assist the interpretation of elemental data. This allowed the determination of the correlations between the metals and the identification of three main factor loadings controlling the metal variability in soils
Chelation treatment can take a long time depending on the method of obtaining the precious metals along with the chelation process picked. Chelation treatment is broadly referred to as a treatment for lead along with other heavy metal poisoning. Chelation has already established itself in the management of metal toxicity and also other metal poisoning, ventricular fibrillation, and hypocalcaemia. Chelation therapy is conducted in the event of copper, iron, aluminum and lead overload and then in some heavy metal toxicities. Chelation is one kind of many successful treatments against poisoning.. Chelation therapy is a impressive treatment for eradicating heavy metals, unwanted calcium supplements, and artery-damaging chemical compounds from your circulatory system. Deplaquing is actually a therapy that gives EDTA to people that, predominantly, have stopped up arterial blood vessels. Metal detoxification has also been reviewed like a cure for other signals which include coronary artery disease, ...

Though unproven, genetic susceptibility to high mercury (Hg) body burden has been suggested as an autism risk factor in a subset of children. We hypothesized that exposure to safe Hg levels could be implicated in the etiology of autism if genetic susceptibility altered Hgs metabolism or intracellular compartmentalization. Genetic sequences of four genes implicated in the transport and response to Hg were screened for variation and association with autism. LAT1 and DMT1 function in Hg transport, and Hg exposure induces MTF1 and MT1a. We identified and characterized 74 variants in MT1a, DMT1, LAT1 and MTF1. ...
from what we understand research wise, Lyme disease, which is technically a bacteria or spirochete, has been shown to live inside of certain nematodes, which is essentially a type of parasite like a roundworm. So parasites can actually house Lyme disease, or bacteria, or other viruses, or other bacteria. And then, parasites are also a huge sponge for absorbing heavy metals.. And heres whats really crazy to think about. Parasites absorb heavy metals. So if you run a test and think, Oh, man, I must have a ton of heavy metals because Dr. Jay and Dr. Scott are saying heavy metals are like this big thing, and all of a sudden you have like no heavy metals show up or even false lows, and lets say you ran the test right, it could mean that you also have a massive parasite issue because parasites absorb heavy metals. And if you didnt deal with the parasites, then the heavy metals are still in the parasite, which then means that, from a testing standpoint, can still come up negative.. ...
3. Iron, B12, folate - optimal levels. B12 and folate are now known to support repairing DNA/genetic disturbances (in therapeutic doses). These nutrients also support methylation in the liver - when this pathway doesnt work we have a higher risk of heart disease. DNA changes can be reversed with big enough doses of MetagenB12/folate, Stem Enhance and anti-inflammatory substances such as MetaPure EPA/DHA. Anesthetics bind with B12 and make it unavailable. We then need doses (2000-4000mcg daily) in order to 1. Pull out anesthetics and 2. Start the DNA repair process. Less than that simply doesnt cut it.4. Heavy Metal Toxicity.Heavy metals are positively charged. They create inflammation in the body. Cancer is negatively charged. When there is cancer in the body we always find heavy metal toxicity.

The effects of multiple heavy metal stress on the activity of antioxidative enzymes and lipid peroxidation were studied in leaves and roots of two mangrove plants, Kandelia candel and Bruguiera gymnorrhiza, grown under control (10 parts per thousand. NaCl nutrient solution) or five levels of multiple heavy metal stress (10 parts per thousand. NaCl nutrient solution containing different concentration of Pb2+ Cd2+, and Hg2+). Leaves and roots of control and heavy metal-stressed plants were harvested after two months. In leaves of heavy metal-stressed plants superoxide dismutase (SOD) and peroxidase (POD) activities fluctuated in different stress levels compared to the control, while catalase (CAT) activity increased with stress levels in K candel, but remained unchanged in leaves of B. gymnorrhiza. In comparison with the control, the dynamic tendency of SOD, CAT, and POD activities in roots of heavy metal-stressed plants all ascended, and then declined. The increase in enzyme activities ...
Recently, there has been considerable interest in the use of terrestrial plants as a green technology for the remediation of surface soils contaminated with toxic heavy metals. This technology, termed phytoremediation, uses plants to extract heavy metals from the soil and to concentrate them in the harvestable shoot tissue (1, 2). A major factor behind the interest in phytoremediation of metal-polluted soils has been the growing awareness of the existence of a number of metal-accumulating plant species. These plant species, called hyperaccumulators, are endemic to metalliferous soils and can accumulate and tolerate high levels of heavy metals in the shoot (3, 4). Among the best known hyperaccumulators is Thlaspi caerulescens. This member of the Brassicaceae family has attracted the interest of plant biologists for over a century because of its ability to colonize calamine and serpentine soils containing naturally elevated levels of heavy metals such as Zn, Pb, Cd, Ni, Cr, and Co. Certain ...
Heavy metal contamination has been a significant problem limiting agricultural development, but sugarcane has recently emerged as a valuable phytoremediator. To better understand the molecular mechanism behind sugarcanes metal tolerance, it is necessary to analyze the expression of a novel gene(s) by qRT-PCR. Importantly, introducing internal reference gene(s) should be selected based upon gene stable expression, the inclusion of which could enhance both the accuracy and reliability of this method. In this study, 13 candidate genes were selected and evaluated stability of each genes. The results derived by statistical algorithms were then validated by normalizing the expression of metal related gene ScMTP (GenBank Accession No. KP864146), ScMT2-1-3 (GenBank Accession No. JQ627644), ScMPP (GenBank Accession No. CA267392.1) and ScHMA1 (GenBank Accession No. CA156665.1). Collectively, our qRT-PCR results indicated that in heavy metal-exposed sugarcane, APRT was the better single internal control in
A long-term study programme has evaluated heavy metals in the Bahía Blanca estuary, considering occurrence, concentration and distribution in the estuarine sediments, as well as their corresponding geochemical partitioning in the ,62 µm grain size fraction of the sediment. Total concentrations of heavy metals (Cd, Zn, Cu, Cr, Pb, Fe) have been determined through flameless atomic absorption spectrophotometry (AAS). Geochemical partitioning of these metals was determined following a sequential extraction technique. Furthermore, heavy metal distribution was studied against organic matter concentration within the sediments.. The results allow the characterization of the spatial distribution of the metals, together with their accumulation areas and potential sources. Bahía Blanca estuarine sediments have low to medium heavy metal concentrations. The geochemical partitioning indicated that many bioavailable species occur within the system, including those of highly toxic elements such as cadmium. ...
Using 3 cyprinid fish species zebra fish, rare minnow, and juvenile grass carp, we conducted assays of lethal reaction and ventilatory response to analyze sensitivity of the fish to 4 heavy metals. Our results showed that the 96 h LC50 of Hg(2+) to zebra fish, juvenile grass carp, and rare minnow were 0.14 mg L(-1), 0.23 mg L(-1), and 0.10 mg L(-1), respectively; of Cu(2+)0.17 mg L(-1), 0.09 mg L(-1), and 0.12 mg L(-1) respectively; of Cd(2+)6.5 mg L(-1), 18.47 mg L(-1), 5.36 mg L(-1), respectively; and of Zn(2+)44.48 mg L(-1), 31.37 mg L(-1), and 12.74 mg L(-1), respectively. Under a 1-h exposure, the ventilatory response to the different heavy metals varied. Ventilatory frequency (Vf) and amplitude (Va) increased in zebra fish, juvenile grass carp, and rare minnows exposed to Hg(2+) and Cu(2+) (P|0.05), and the Vf and Va of the 3 species rose initially and then declined when exposed to Cd(2+). Zn(2+) had markedly different toxic effects than the other heavy metals, whose Vf and Va gradually decreased
In this thesis the development of methods for handling the problems associated with analyzing trace elements in complex matrixes using inductively coupled plasma mass spectrometry is presented. Trace elements such as Cu, Fe, Se, and Zn, to name a few, do play important roles in different organisms. Therefore it can be of importance to study trace elements in different samples of biological origin. As trace elements are low in abundance, sensitive instrumental techniques such as inductively coupled plasma mass spectrometry (ICP-MS) are required for accurate determination. Due to the complexity of samples with biological origin, careful method development, both regarding the sample preparation and instrumental analysis has to be performed to minimize negative effects on the instrument signal and introduction of interferences.. For example the metal contents of mink livers were analyzed, after bomb digestion to investigate if the metal concentration could be linked to changes in the organ ...
Influence of some heavy metals on growth, alkaloid content and composition in Catharanthus roseus L., NK Srivastava, AK Srivastava
Lead mining and smelting may be major sources of heavy metal contamination to ground water. Lead poisoning affects every system in the body. It can cause learning disabilities, behavioral problems and, at high levels, can cause seizures, comas, stroke, and kidney disease. Cadmium exposure can cause nausea, vomiting, diarrhea, muscle cramps and convulsions. Long term exposure to cadmium can cause kidney, liver, bone and red blood cell damage. All properties with private wells being sold or transferred in Jasper County must have the well water tested for lead and cadmium. A DNR certified tester is required to collect the sample. The new owner and the Jasper County Health Department shall receive a copy of the test results. If test results indicate heavy metal contamination above the EPA action levels then treatment is strongly recommended. EPA established an action level for lead at 15 parts per billion (ppb ...
Green preparation of heavy metal saponin complexes has been successfully optimized by direct combination between crude extract of Olea Europaea and Citrus Aurantium with divalent heavy metals, Pb2+ and Cd2+. The main operating factors affecting preparation process were investigated and evaluated in terms of setting time, heavy metal ion concentration, crude extract concentration, and pH value of the medium. Saponin complexes had been prepared using the optimum concentrations of heavy metal ions (120 ppm) and optimum concentration of crude extract (600 ppm) in the slightly alkaline medium. The presence of saponin in plants was confirmed by chemical tests and UV/Vis analysis. Amount of prepared saponine complexes has the order: (Pb/Olive) | (Cd/Olive) | (Pb/Citrus) | (Cd/Citrus). In this process, saponins was isolated and heavy metals were eliminated by a simple, faster and without a huge amount of solvents. The process itself seems to be green isolation of saponins from plants, green removal of heavy

The origin of the term heavy metal in a musical context is uncertain. The phrase has been used for centuries in chemistry and metallurgy, where the periodic table organizes elements of both light and heavy metals (e.g., uranium). An early use of the term in modern popular culture was by countercultural writer William S. Burroughs. His 1962 novel The Soft Machine includes a character known as Uranian Willy, the Heavy Metal Kid. Burroughs next novel, Nova Express (1964), develops the theme, using heavy metal as a metaphor for addictive drugs: With their diseases and orgasm drugs and their sexless parasite life forms-Heavy Metal People of Uranus wrapped in cool blue mist of vaporized bank notes-And The Insect People of Minraud with metal music.[90] Inspired by Burroughs novels,[91] the term was used in the title of the 1967 album Featuring the Human Host and the Heavy Metal Kids by Hapshash and the Coloured Coat, which has been claimed to be its first use in the context of music.[92] The ...
The objective of this research was to validate the use of sodium sulfide and ferrous sulfate in reducing hexavalent chromium and removing heavy metals from electroplating, and industrial wastewaters. Jars tests, and dynamic tests, were conducted using distilled water, electroplating rinse waters, and industrial wastewaters from Tinker AFB Industrial Waste Treatment Plant. Optimum process parameters were evaluated as well as analysis of the effects of typical contaminants and complexing agents, along with the effects of the process on downstream treatment. The information obtained verified that the sulfide treatment process will meet discharge permit requirements while reducing chemical and disposal costs. The results were the basis for continuing to Phase II, Pilot-Scale Study On Actual Industrial Wastewaters.

This study was carried out to identify and assess the water quality of the Chari River. The Chari, 1200 km long, is Chads major water source. Municipal sewage, industrial wastewater discharge, and seasonal run-off from agriculture are regularly fed into the river. Several trace metals such as Cu, Zn, Fe, Ni, Cr, Mn, and Cd, were measured in different sampling stations located along the Chari River at NDjamena in different campaigns from 2008 to 2010. Overall, manganese, zinc, chromium, and copper concentration levels were mainly in the range of the permissible limits prescribed by WHO guidelines (WHO 2011). Nickel, iron, and cadmium concentrations were still high. This preliminary study allowed us to identify the magnitude of toxic pollutants, which are responsible for Chari River water contamination in the study area. This study revealed that urgent measures must be taken to protect the local people from health problems resulting from high concentrations of heavy metals.
Heavy metal contamination is an important environmental issue. Heavy metals can contaminate soil and water sources in areas where mining and various industrial proccesses have occurred. These metals can then be absorbed into plants which are subsequently eaten by various animals. Heavy metals are usually not excreted readily and are retained within the body of an animal that has consumed a contaminated food source. Cadmium in particular is not excreted readily from the mammals and is known to cause various etiologies stemming from its build-up in organs (Gobe and Cramer). In order to develop a mock cadmium-sensing system in plants the promoter for the Cd-transporter gene AtMRP3 (At3g13080) from A. thaliana was transformed into N. tabacum cells. AtMRP3 is utilized by the plant to sequester Cd2+ in the vacuole, which is thought to prevent the cation from interfering with various biological processes (Bovet et al.). Besides being highly induced by cadmium, AtMRP3 has also shown similar induction ...

N2 - Concentrations of heavy metals in water and sediment samples of Buriganga River in the capital city Dhaka, Bangladesh, were studied to understand the level of heavy metals and their source apportionment. The results showed that the mean concentrations of heavy metals both in water and sediment samples were very high and, in most cases, exceeded the permissible limits recommended by the Bangladesh government and other international organizations. Significantly higher concentrations of Pb, Cr, Mn, Co, Ni, Cu, Zn, As, and Cd were found in sediment samples. However, average concentrations of metals both in water and sediment samples were above the effect range ...
Chelation treatment can take a long time depending on the method of obtaining the precious metals along with the chelation process picked. Chelation treatment is broadly referred to as a treatment for lead along with other heavy metal poisoning. Chelation has already established itself in the management of metal toxicity and also other metal poisoning, ventricular fibrillation, and hypocalcaemia. Chelation therapy is conducted in the event of copper, iron, aluminum and lead overload and then in some heavy metal toxicities. Chelation is one kind of many successful treatments against poisoning.. Chelation therapy is a impressive treatment for eradicating heavy metals, unwanted calcium supplements, and artery-damaging chemical compounds from your circulatory system. Deplaquing is actually a therapy that gives EDTA to people that, predominantly, have stopped up arterial blood vessels. Metal detoxification has also been reviewed like a cure for other signals which include coronary artery disease, ...
Metal toxicity or metal poisoning is the toxic effect of certain metals in certain forms and doses on life. Some metals are toxic when they form poisonous soluble compounds. Certain metals have no biological role, i.e. are not essential minerals, or are toxic when in a certain form. In the case of lead, any measurable amount may have negative health effects. Often heavy metals are thought as synonymous, but lighter metals may also be toxic in certain circumstances, such as beryllium and lithium. Not all heavy metals are particularly toxic, and some are essential, such as iron. The definition may also include trace elements when in abnormally high doses may be toxic. An option for treatment of metal poisoning may be chelation therapy, which is a technique which involves the administration of chelation agents to remove metals from the body. Toxic metals sometimes imitate the action of an essential element in the body, interfering with the metabolic process resulting in illness. Many metals, ...
A novel thermosensitive adsorbent was developed, which adsorbs and/or desorbs heavy metals through temperature swing process. The gel-type and polymer-type adsorbents, composed of N-isopropylacrylamide (NIPA) as a thermosensitive component and 2-methacryloyloxyethyl phosphate (MEP) as an interactive component, were prepared by free radical copolymerization. For each type of poly(NIPA-co-MEP), phase transitions and temperature dependences for the amount of Cu, a model metal ion, adsorbed was examined. The proposed mechanism associated with the temperature swing adsorption (TSA) of Cu to poly(NIPA-co-MEP) is as follows. In the case of the shrinking gel at higher temperatures, two MEP groups are positioned so as to interact with one Cu ion, while in the swelling gel at lower temperatures, Cu is desorbed from isolated MEP groups. In the case of copolymers, at temperatures lower than the lower critical solution temperature (LCST), two MEP groups interact with one Cu ion as well as those in shrunken ...

Heavy metals are one of the more serious pollutants in our natural environments due to their toxicity. Fish is one of the most important food sources and thus, intake of trace elements from capture fish, especially toxic elements if one of great concern for human health. Concentrations of some heavy metals in the muscle of Channa striata (Bloch, 1793) will be studied from December 2017 to December 2019. The study area, Hlaing River segment located in Hmawbi Township, Yangon Region was chosen at the vicinity of Myaungtagar industrial zone due to the presence of different types of factories. Concentration of heavy metals such as cadmium (Cd), mercury (Hg), lead (Pb), copper (Cu), zinc (Zn), chromium (Cr) and arsenic (As) in water samples and fish muscle will be determined monthly. For the purpose of heavy metal determination in fish muscle will be carried out in accordance with seasons, size and bioaccumulation factor. The samples will be analyzed using Atomic Absorption Spectrophotometer in ...
TY - JOUR. T1 - Heavy metal immobilization through phosphate and thermal treatment of dredged sediments. AU - Ndiba, Peter. AU - Axe, Lisa. AU - Boonfueng, Thipnakarin. PY - 2008/2/1. Y1 - 2008/2/1. N2 - Disposal of dredged sediments is expensive and poses a major challenge for harbor dredging projects. Therefore beneficial reuse of these sediments as construction material is highly desirable assuming contaminants such as heavy metals are immobilized and organics are mineralized. In this research, the effect of the addition of 2.5% phosphate, followed by thermal treatment at 700°C, was investigated for metal contaminants in dredged sediments. Specifically, Zn speciation was evaluated, using X-ray absorption spectroscopy (XAS), by applying principal component analysis (PCA), target transformation (TT), and linear combination fit (LCF) to identify the main phases and their combination from an array of reference compounds. In dredged sediments, Zn was present as smithsonite (67%) and adsorbed to ...

This list is not exhaustive, but if all these results were completely normal and that person was taking my basic package of nutritional supplements, then it would make it unlikely that there was anything seriously amiss with respect to micronutrient status. Increasingly, I now do screening tests for toxic stress such as DNA adducts, or Fat biopsy for pesticides or Volatile Organic Compounds. There is no one single best test for heavy metal toxicity - some people are poor detoxifiers and so hair, blood, and sweat analysis may show normal results and toxicity may only be demonstrated by a challenge test such as Mercury - Kelmer test. This test can be done for other heavy metals, not just mercury. Finally, chemical poisoning and chemical sensitivity go together. Where there is poisoning there will be sensitivity and vice versa. This means Lymphocyte sensitivity to metals and chemicals can be a very useful way of screening for a variety of toxic exposures (including silicone). People are much better ...
Published December 16 2013. Toxins can have a big impact on ones health, and while there are many different toxins out there, in this article Im going to focus on the toxic metals. Ill be using the terms toxic metals and heavy metals interchangeably throughout this article. Although any heavy metal can cause damage in excess (i.e. iron or copper), the focus of this article will be on those heavy metals which are toxic even in smaller amounts. There are numerous toxic metals, but Im mainly going to talk about mercury, cadmium, aluminum, lead, and arsenic. Not all of these toxic metals directly affect thyroid health, but this of course doesnt mean they wont have a negative impact on ones overall health.. Just as is the case with other toxins, nobody is going to be able to completely eliminate all of the toxic metals from their body. Just about everyone has mercury, cadmium, arsenic, and other metals stored in their tissues. Some people have small amounts of these toxins, while other ...
Hair samples of individual were analysed for heavy metals (Cd, Cr, Pb and As) across gender and various occupational distributions by Atomic Absorption Spectrophotometric technique (AAS). The results of replicate analysis shows the following mean concentrations (mg/kg): Cd = 27.8 ± 8.0, Cr = 2.70 ± 0.7, Pb = 73.8 ± 42.3 and As = 222 ± 34.1. The coefficients of variation for the total distribution is; Cd = 28%, Cr = 26%, Pb = 57% and As = 15%. The distribution of the metals follows the series in decreasing order of As > Pb > Cd > Cr, while their coefficients of variation is in the order of Pb > Cd >Cr > As. The result shows the presence of all the metals in relatively large amounts with As having the highest concentration between the two genders. The difference between male and female concentration could be due to individual differences in exposure to heavy metal load as a result of habitual or environmental factors.

Metal pollution and its health effects present a challenge currently facing the developing countries. Metal poisoning is usually difficult and expensive to assess or screen in these countries due to limited resources, which means that policies, guidelines, regulations and institutional managements are limited. Hair and nail as biopsy materials were suggested as more attractive biomarkers in assessing heavy metals environmental exposure. This paper deals with quantitative determination of lead (Pb), cadmium (Cd), calcium (Ca), zinc (Zn), and iron (Fe) in fingernails of children (n = 200) in urban and rural areas using atomic absorption spectrometry. Factors that were suspected to influence the accumulation of Pb and Cd in children were obtained through a questionnaire. The mean levels of heavy metals in children in urban areas were found to be higher (27.5 ± 1.8 μg/g Pb and 0.73 ± 0.08 μg/g Cd) than in rural areas (19.7 ± 0.9 μg/g Pb and 0.44 ± 0.06 μg/g Cd). The difference was ...
The results indicated about one-third of the samples, which include 95 from South Asian stores in New Jersey and 23 from stores in Mumbai and New Delhi in India, contained lead levels above the limit set by the US FDA. Sindoor and Kajal are well known to contain lead and other heavy metals with risk of kidney, hepatic, skin disorders. Risk of heavy metals on skin leads to DNA damage, Kertaodermas and skin ulceration, nail and teeth changes, said Dr Nitin S Walia, Senior Consultant, Dermatology, BLK Super Speciality Hospital. Problem is throughout Asia especially India, Pakistan, Middle East, SE Asia.. Sindoor is originally made from Turmeric but synthetic Sindoor is made from highly toxic chemicals such as Mercury Sulfide known as Vermilion and Lead Tetroxide known as Red Lead.. Neelikon has high quality low impurity cosmetic colours under brand name Lavanya which are increasingly preferred by cosmetic producers in India to use in traditional Indian products like Sindoor, Kumkum, Kajal etc. ...

Breathing heavy metal particles, even at levels well below those considered nontoxic, can have serious health effects. Virtually all aspects of animal and human immune system function are compromised by the inhalation of heavy metal particulates.7 In addition, toxic metals can increase allergic reactions, cause genetic mutation, compete with good trace metals for biochemical bond sites, and act as antibiotics, killing both harmful and beneficial bacteria.8 Much of the damage produced by toxic metals stems from the proliferation of oxidative free radicals they cause. A free radical is an energetically unbalanced molecule, composed of an unpaired electron, that steals an electron from another molecule to restore its balance. Free radicals result naturally when cell molecules react with oxygen (oxidation) but, with a heavy toxic load or existing antioxidant deficiencies, uncontrolled free-radical production occurs. Unchecked, free radicals can cause tissue damage throughout the body; ...

One area of concern is heavy metal contamination of waters from industrial discharges and naturally occurring sources. In this study mercury(II) removal from aqueous solution was evaluated using activated carbon adsorption and ion exchange. The results of this project are expected to contribute to a grant which is to demonstrate the application of reverse osmosis and ...
What to do about all those years of stored-up toxins from back when you used to eat processed food, day in and day out? Well, this delicious detoxing juice is one answer. It is rich in toxin-flushing vitamin A, and includes a variety of other minerals and vitamins such as vitamin K, vitamin C., and a whole array of B vitamins.. Cilantro acts as a vacuum cleaner for heavy metal accumulations, and recent research shows that cilantro may be particularly effective in reducing lead accumulation in the body,. This means it is an important ingredient to include in your diet if you or your children have every been exposed to brain debilitating lead poisoning-likely if youve ever lived in a house with old paint.. Tomatoes are a powerful antioxidant, and they also play an important role in keeping your heart healthy. This juice has a wonderfully fresh taste, with a little zing from the cilantro.. ...
According to The Home Medical Encyclopedia, in 1963 about 50% of all Americans suffered from an unrecognized systemic fungal infection. These infections can be brought on by many different factors that alter the optimal state of our intestinal ecology, most notably antibiotics, birth control pills, excessive processed sugar and grain consumption, heavy metal contamination, xenoestrogens, alcohol, smoking, and chronic stress. These factors, in combination with diets severely deficient in active enzymes and probiotics, have paved the way for the most prevalent fungal infection to take over, Candida albicans.. But how does a fungal problem like Candida lead to an eventual cancer diagnosis?. According to Dr. Robert Young:. Bacteria, yeast/fungi, and mold are not the cause of a cancerous condition but are the result and the evidence of cells and tissues biologically transforming from a healthy state into an unhealthy state. Dr. Young astutely observed that, over-acidification of the body leads ...
The toxicity of heavy metals such as lead (Pb), cadmium (Cd) and tin (Sn) has long been known but accidental exposures of large populations to these elements remain unfortunately a topical issue. Chelating agents against Pb, Cd, or Sn poisoning are still limited to classical ligands such as ethylenediamine t Equilibrium Solution Coordination Chemistry
EDTA (ethylenediamine tetra-acetic acid) is an early chelating agent, typically taken via a shot or IV, that is used to detox lead, mercury, copper, iron, arsenic, aluminum and calcium. It is also used as secondary treatment for lead toxicity only.. It is also used to treat arteriosclerosis (plaque deposits inside arteries, eventually resulting in hardening of the affected arteries) and atherosclerosis (arteriosclerosis affecting the arteries that feed heart muscle). While it is not known how EDTA therapy works, it has been well established that it does work, not only to reduce soft plaque, but also to result in reduction of calcium-hardened plaque.. Initially it was believed that EDTA worked as a treatment for martial plaque by binding calcium and removing it from the plaque. But while EDTA is very effective at chelating calcium, this theory or its action on arterial plaque has been disproven.. The current hypothesis is that EDTA chelates free, unbound heavy metals in the blood, such as iron ...

1. INTRODUCTION. Nowadays, heavy metals are among the most important pollutants in source and treated water and becoming a severe public health problem. Chromium, a toxic heavy metal ion, is found in wastewater of various industries, such as paint and pigment manufacturing, stainless steel production, corrosion control, leather tanning, chrome plating and wood preservation [1]. Chromium exists almost exclusively in the Cr(III) oxidation state or in the Cr(VI) oxidation state, however, Cr(VI) is 500 times more toxic than the trivalent form [2]. Thus, the presence of Cr(VI) ions in the environment is posing serious problems and causing great public concern [3]. According to USEPA, the permissible level of Cr(VI) in drinking water should be less than 100 µg/L [4].. Many physical-chemical methods, included reduction [5], ion exchange [6], precipitation [7] and membrane separation [8], have been proposed for Cr(VI) removal from industrial effluent. However, these methods are often inefficient and/or ...
Two practicing physicians, Hyla Cass, M.D., of Pacific Palisades, CA, and Lise Alschuler, N.D., of Bedford, NH, spoke about their experiences using glutathione with their patients.. Cass explained that heavy metal toxicity affects all body systems, especially the cardiovascular system, brain and immune system, and is at the root of many common conditions. [Heavy metals] deplete glutathione, and indeed, low glutathione levels are found in patients who have had these kinds of exposures. A recent study showed that glutathione significantly enhances the release of mercury from brain cells, she stated.. Glutathione supplementation also benefits children with Autism Spectrum Disorders (ASD). Children with ASD have low glutathione status, accompanied by frequent gastrointestinal infections, food sensitivities, autoimmune disorders and neurotoxicity from environmental toxicants and heavy metals. A clinical trial recently showed that glutathione supplementation of autistic children improved ...
