A toxicokinetic model to assess the risk of azinphosmethyl exposure in humans through measures of urinary elimination of alkylphosphates. (1/12)

Azinphosmethyl (APM) is one of the most common insecticides used in fruit farming. The object of this paper is to develop a quick and practical test for assessing the risk for humans coming into contact with APM. It has been shown that the principal component of occupational and/or accidental exposure is through the skin (C. A. Franklin et al., 1981, J. Toxicol. Environ. Health 7, 715-731), but our approach is applicable to exposures via any route or a combination of routes. The method proposed in the present paper can accommodate a single-event exposure or repeated exposures over long periods. Urinary alkylphosphate (AP) metabolites are reliable bioindicators of the presence of APM in the body; they are easily accessible and can be used to estimate APM body burden. We developed a simple toxicokinetic model to link the time varying APM body burden to absorbed doses and to rates of elimination in the form of AP urinary metabolites. Using this model and data available in the literature, we are able to propose a "no observed adverse effect level" (NOAEL) for APM body levels and for corresponding absorbed doses. We have established that after a single exposure, the safe limit corresponding to the NOAEL is reached at a cumulative 0.215 mumoles AP/kg bw eliminated in urine in the first 24 hours following the beginning of exposure. For repeated daily exposures at steady state, the corresponding urinary AP metabolite level is equal to a cumulative 0.266 mumoles AP/kg bw eliminated per 24 hours.  (+info)

Work characteristics and pesticide exposures among migrant agricultural families: a community-based research approach. (2/12)

There are few data on pesticide exposures of migrant Latino farmworker children, and access to this vulnerable population is often difficult. In this paper we describe a community-based approach to implement culturally appropriate research methods with a migrant Latino farmworker community in Oregon. Assessments were conducted in 96 farmworker homes and 24 grower homes in two agricultural communities in Oregon. Measurements included surveys of pesticide use and work protection practices and analyses of home-dust samples for pesticide residues of major organophosphates used in area crops. Results indicate that migrant farmworker housing is diverse, and the amounts and types of pesticide residues found in homes differ. Azinphos-methyl (AZM) was the pesticide residue found most often in both farmworker and grower homes. The median level of AZM in farmworker homes was 1.45 ppm compared to 1.64 ppm in the entry area of grower homes. The median level of AZM in the play areas of grower homes was 0.71 ppm. The levels of AZM in migrant farmworker homes were most associated with the distance from fields and the number of agricultural workers in the home. Although the levels of AZM in growers and farmworker homes were comparable in certain areas, potential for disproportionate exposures occur in areas of the homes where children are most likely to play. The relationship between home resident density, levels of pesticide residues, and play behaviors of children merit further attention.  (+info)

Contamination of rural surface and ground water by endosulfan in farming areas of the Western Cape, South Africa. (3/12)

BACKGROUND: In South Africa there is little data on environmental pollution of rural water sources by agrochemicals. METHODS: This study investigated pesticide contamination of ground and surface water in three intensive agricultural areas in the Western Cape: the Hex River Valley, Grabouw and Piketberg. Monitoring for endosulfan and chlorpyrifos at low levels was conducted as well as screening for other pesticides. RESULTS: The quantification limit for endosulfan was 0.1 microg/L. Endosulfan was found to be widespread in ground water, surface water and drinking water. The contamination was mostly at low levels, but regularly exceeded the European Drinking Water Standard of 0.1 microg/L. The two most contaminated sites were a sub-surface drain in the Hex River Valley and a dam in Grabouw, with 0.83 +/- 1.0 microg/L (n = 21) and 3.16 +/- 3.5 microg/L (n = 13) average endosulfan levels respectively. Other pesticides including chlorpyrifos, azinphos-methyl, fenarimol, iprodione, deltamethrin, penconazole and prothiofos were detected. Endosulfan was most frequently detected in Grabouw (69%) followed by Hex River (46%) and Piketberg (39%). Detections were more frequent in surface water (47%) than in groundwater (32%) and coincided with irrigation, and to a lesser extent, to spraying and trigger rains. Total dietary endosulfan intake calculated from levels found in drinking water did not exceed the Joint WHO/FAO Meeting on Pesticide Residues (JMPR) criteria. CONCLUSION: The study has shown the need for monitoring of pesticide contamination in surface and groundwater, and the development of drinking water quality standards for specific pesticides in South Africa.  (+info)

Pesticide resistance via transposition-mediated adaptive gene truncation in Drosophila. (4/12)

To study adaptation, it is essential to identify multiple adaptive mutations and to characterize their molecular, phenotypic, selective, and ecological consequences. Here we describe a genomic screen for adaptive insertions of transposable elements in Drosophila. Using a pilot application of this screen, we have identified an adaptive transposable element insertion, which truncates a gene and apparently generates a functional protein in the process. The insertion of this transposable element confers increased resistance to an organophosphate pesticide and has spread in D. melanogaster recently.  (+info)

Role of neonicotinyl insecticides in Washington apple integrated pest management. Part I. Control of lepidopteran pests. (5/12)

Three neonicotinyl insecticides, acetamiprid, thiacloprid and clothianidin, were evaluated for their impact on four species of lepidopteran pests of apple in Washington, the codling moth, Cydia pomonella (L.), the Pandemis leafroller, Pandemis pyrusana Kearfott, and the obliquebanded leafroller, Choristoneura rosaceana (Harris), and Lacanobia subjuncta (Grote & Robinson). None of the neonicotinyl insecticides demonstrated sufficient activity against P. pyrusana, C. rosaceana, or L. subjuncta to warrant field trials. Conversely, all had some activity against one or more stages of C. pomonella. Acetamiprid was highly toxic to larvae in laboratory bioassays, and had relatively long activity of field-aged residues (21 days). It also showed some toxicity to C. pomonella eggs (via topical exposure) and adults. Acetamiprid provided the highest level of fruit protection from C. pomonella attack in field trials conducted over five years in experimental orchards with extremely high codling moth pressure. Thiacloprid performed similarly in bioassays, but fruit protection in field trials was slightly lower than acetamiprid. Clothianidin showed moderate to high toxicity in bioassays, depending on the C. pomonella stage tested, but poor fruit protection from attack in field trials. None of the neonicotinyl insecticides were as toxic to larvae or effective in protecting fruit as the current standard organophosphate insecticide used for C. pomonella control, azinphosmethyl. However, both acetamiprid and thiacloprid should provide acceptable levels of C. pomonella control in commercial orchards where densities are much lower than in the experimental orchards used for our trials. The advantages and disadvantages of the neonicotinyl insecticides as replacements for the organophosphate insecticides and their role in a pest management system for Washington apple orchards are discussed.  (+info)

 (+info)

Four organophosphorus pesticides (azinphos-methyl, diazinone, dimethoate, and pirimiphos-methyl), and one carbamate (benomyl) were tested for cytotoxicity, reverse mutation and gene conversion in Saccharomyces cerevisiae D7, with and without the S9 metabolic system. Furthermore, two mixtures of the above compounds, namely benomyl + pirimiphos-methyl (6/1 ratio) and dimethoate + diazinone + azinphos-methyl (10/4/6 ratio) were tested in the same experimental model. Azinphos-methyl, benomyl, and pirimiphos-methyl alone did not induce any genotoxic effect, whereas azinphos-methyl and diazinone were active in inducing reversion and gene conversion. The benomyl + pirimiphos-methyl mixture did not show any genotoxic activity. The dimethoate + diazinone + azimphos-methyl mixture was genotoxic, although an antagonistic effect between the components was observed. The addition of S9 post-mitochondrial liver fraction decreased the activity of both single and mixed genotoxic agents.. ...
Beyond Pesticides, July 5, 2012) After a 2006 cancellation of uses due to unreasonable risks to farmworker health and the environment, and a 6-year phase out scheduled to conclude this September, the U.S. Environmental Protection Agency (EPA) is conducting a risk-benefit analysis to make a determination whether to keep in place or amend the cancellation order for the organophosphate azinphos-methyl (AZM), citing new information on the economic costs of using alternatives. In 2001, EPA found that insecticides azinphos-methyl (AZM) posed unacceptable risks to farmworkers and announced that 28 crop uses were being canceled, seven crop uses were to be phased-out over four years, and eight crop uses were to be allowed to continue under a "time-limited" registration for another four years. Farmworker advocates challenged that decision in federal court citing that EPA failed to take into account the costs of poisoning workers, exposing children, and polluting rivers and streams.

BACKGROUND:. Epidemiologic analysis of acute, reversible respiratory health effects is uncommonly performed, yet these are important health outcomes because acute responses by the respiratory defense system appear to represent one end of the continuum toward progressive, chronic and potentially disabling physiologic changes. Repeatable epidemiologic studies of dose-response relationships necessitate accurate measures of dose. However, in occupational and environmental settings, exposure to a toxin is seldom found at identical concentrations and/or particle sizes among persons with the same activity patterns. In addition, air concentration does not account for factors such as clearance or metabolism which may alter the biologically effective tissue dose. These factors cause the target tissue dose of the toxin to vary greatly despite exposure to similar air concentrations.. DESIGN NARRATIVE:. The results of these toxicokinetic models were individual measures of tissue dose used in a 2-stage ...

The inhibition of acetylcholinesterase in the presence of selected organothiophosphates (diazinon, malathion, chlorpyrifos, azinphos-methyl, phorate) and their oxo-analogues (diazoxon, malaoxon, chlorpyrifos-oxon, azinphos-methyl-oxon, phorate-oxon) was examined. Experimental conditions were optimized to detect the lowest posible concentrations of these compounds using AChE test. IC50 values were determined for all the mentioned compounds. Investigated organothiophosphates have been converted into their oxo-analogues in the presence of the enzyme myeloperoxidase. Oxidation products were detected using UPLC and GC/MS analysis. It was found that the products are stable within minimum 1h. In order to optimize oxidation procedure and achieve maximum concentrations of oxons, the optimal concentrations of H2O2 (50 μM) and MPO (100 nM) were determined. Also, the optimal incubation time of OPs and MPO (10 min), as well as the optimal pH (6) and temperature (25 °C) were estimated. Oxidation of ...

Methylmercury (MeHg), known for well over a century as a neurotoxin in adults, has more recently been studied for potential detrimental effects during early brain development. While several studies have estimated mercury exposure, they usually rely on either a single biomarker or questionnaire data, each of which has limitations. The goal of this paper was to develop a toxicokinetic model that incorporates both biomarker and questionnaire data to estimate the cumulative exposure to MeHg through seafood consumption using data collected from the Childhood Autism Risks from Genetics and the Environment (CHARGE) study.We utilized a previously described discrete-time model that estimates blood MeHg concentration given a piecewise-constant ingestion rate and single-compartment pharmacokinetics. We measured newborn bloodspot Hg concentrations and obtained information pertaining to maternal fish consumption using a questionnaire.

Vesicular stomatitis is an economically important arboviral disease of livestock. Viremia is absent in infected mammalian hosts, and the mechanism by which insects become infected with the causative agents, vesicular stomatitis viruses, remains unknown. Because infected and noninfected insects potentially feed on the same host in nature, infected and noninfected black flies were allowed to feed on the same host. Viremia was not detected in the host after infection by a black fly bite, but because noninfected black flies acquired the virus while co-feeding on the same host with infected black flies, it is concluded that a viremic host is not necessary for an insect to be infected with the virus. Thus co-feeding is a mechanism of infection for an insect-transmitted virus. ...

Methylmercury (MeHg) is a potent neurotoxin, and human beings are mainly exposed to this pollutant through fish consumption. We addressed the question of whether a diet mimicking the fish consumption of Wayanas Amerindians from French Guiana could result in observable adverse effects in mice. Wayanas adult men are subjected to a mean mercurial dose of 7 g Hg/week/kg of body weight. We decided to supplement a vegetarian-based mice diet with 0.1% of lyophilized Hoplias aimara fish, which Wayanas are fond of and equivalent to the same dose as that afflicting the Wayanas Amerindians. Total mercury contents were 1.4 ± 0.2 and 5.4 ± 0.5 ng Hg/g of food pellets for the control and aimara diets, respectively. After 14 months of exposure, the body parts and tissues displaying the highest mercury concentration on a dry weight (dw) basis were hair (733 ng/g) and kidney (511 ng/g), followed by the liver (77 ng/g). Surprisingly, despite the fact that MeHg is a neurotoxic compound, the brain accumulated low levels
Animated coloured scanning electron micrograph (SEM) of Black fly larva (Simulium hippovorum). Note the ribbon of silk coming from the mouth area. All known species of black flies produce silk for mooring lines for anchorage to substrates in flowing water. A pair of silk glands run the length of the body, the strands of silk emerge from a silk duct below the mouth and are cut and guided by a series of teeth on the mandible and hypostoma. Black flies are considered a human pest in some areas of the US and Canada. Adult females of certain species are fierce biters, whereas others are strictly a nuisance by their presence around exposed skin areas. Female black flies require a blood meal; males feed mainly on nectar. Black flies can transmit filarial worms to humans resulting in a disease called onchocerciasis, which cause blindness. - Stock Video Clip K006/9266
In southern California, ocular infections caused by Onchocerca lupi were diagnosed in 3 dogs (1 in 2006, 2 in 2012). The infectious agent was confirmed through morphologic analysis of fixed parasites in tissues and by PCR and sequencing of amplicons derived from 2 mitochondrially encoded genes and 1 nuclear-encoded gene. A nested PCR based on the sequence of the cytochrome oxidase subunit 1 gene of the parasite was developed and used to screen Simulium black flies collected from southern California for O. lupi DNA. Six (2.8%; 95% CI 0.6%-5.0%) of 213 black flies contained O. lupi DNA. Partial mitochondrial16S rRNA gene sequences from the infected flies matched sequences derived from black fly larvae cytotaxonomically identified as Simulium tribulatum. These data implicate S. tribulatum flies as a putative vector for O. lupi in southern California ...

An arrangement for driving out volatile impurities from a ground water with a well shaft extending to the region of the ground water to be purified, the arrangement comprises an element for producing a negative pressure in the well shaft and supplying a gas underneath a water level in the well shaft, an element for providing a plurality of capillary openings in an upper sieve wall portion of the well shaft at least in a purification region between a gas inlet and a water level in the well shaft to enhance a laminary flow of ground water with relatively high speed, the capillary openings forming a greater free throughflow surface than a remaining portion of the well shaft.
In the Western Cape the number of streams suitable for trout has declined significantly over the last 50 years. The reason for this is primarily habitat degradation, dam construction and water abstraction for agricultural use. One of the few remaining pristine trout streams is the Jan du Du Toits River which rises in the Waaihoek area of the Greater Hex River range of mountains. Unfortunately the condition of rainbow trout in this stream is now considered poor due to the increasing incidence of deformities. This is no doubt the result of a genetic bottleneck in the population caused by the limited number of fingerlings in the original stocking of the 1960s and the fact that the steep incline and numerous waterfalls in the system has limited the upstream migration of fish leaving relatively isolated pockets of trout throughout the river.. A probable solution to this problem lies in Cape Natures Rehabilitation Programme for a number of Cederberg streams which includes the removal of rainbow ...

ENGLISH SUMMARY : Public institutions in South Africa are increasingly required to respond effectively to serious societal problems. The year-on-year increase in the abuse of methamphetamine over the last decade in the Western Cape represents one such societal problem that needs to be effectively managed by public institutions in the Western Cape Province. Methamphetamine abuse is having a devastating effect on local communities and is causing irreparable damage to the lives of thousands of users and their families. Despite significant drug abuse prevention efforts of various public institutions, the private sector and local communities, methamphetamine abuse is fast becoming a societal problem of epidemic proportions. A definite need exists for re-thinking the way in which drug abuse is being managed in South Africa and the Western Cape Province in particular. Internationally, there seems to be general consensus that drug abuse needs to be addressed from a multi-disciplinary approach that will ...
Onchocerciasis is a neglected tropical disease that has plagued mankind for decades with pathologies that involve the eyes and the skin. The WHO and the global health community have earmarked the disease for global elimination by 2045. However, as control programmes shift focus from reduction of the burden of the disease to elimination, new tools and strategies may be needed to meet targets. Monitoring|i| Onchocerca volvulus |/i|larvae in the black fly vectors is an important tool needed to monitor disease dynamics and certify elimination. For decades, human landing collections have been the sole means of acquiring vectors for monitoring of the disease. This procedure has been plagued with ethical concerns and sometimes the inability to harvest enough black flies needed to carry out effective monitoring. Since the 1960s, the WHO recognized the need to replace human landing collections but relatively few field studies have designed and tested alternative traps. This review article systematically

It has become for me the saddest day of the year, any year, which no amount of bright face paint, tailored outfits, twirling umbrellas or "moppies" can assuage.. Tweede Nuwejaar - marked informally as a public holiday in the Western Cape except when January 1 falls on a Sunday and the entire country enjoys the holiday on the 2nd.. More than any attempt by the state to regulate how we mark or commemorate important dates in our countrys history, this non-holi-day causes me to pause. Even for one who must only know these things vicariously through the recorded hurt of forbears, who can have no conscious memory of enslavement or dispossession, of losing oneself and gods gifted place on this earth to a more powerful - or perhaps more devious - conqueror, Tweede Nuwejaar connotes immense pain.. The Minstrels who take to the streets of Cape Town each year to "celebrate" Tweede Nuwejaar, can do little to mitigate the inglorious history underpinning this day. On the contrary, it is precisely because ...

The pH of ground water will vary depending on the composition of the rocks and sediments that surround the travel pathway of the recharge water infiltrating to the ground water. Ground water chemistry will also vary depending on how long the existing ground water is in contact with a particular rock. The chemical composition of the bedrock tends to stabilize (buffer) the pH of the ground water. The longer the contact time, the larger the effect of the rock chemistry on the composition and pH of the ground water. Ground water passing through carbonate-rich rocks (e.g., limestones and marbles) will usually have pH values greater than 7 as the acidic water is "neutralized." If the geology of the aquifer containing the ground water has few carbonate rocks (e.g., sandstones, metamorphic granitic schists and gneisses; volcanic rocks, etc.) the ground water will tend to remain acidic ...

Only four genera in the family Simuliidae, Simulium, Prosimulium, Austrosimulium, and Cnephia, contain species that feed on people, though other species prefer to feed on other mammals or on birds. Simulium, the type genus, is the most widespread and is a vector for several diseases, including river blindness. Mature adults can disperse tens or hundreds of kilometers from their breeding grounds in fresh flowing water, under their own power and assisted by prevailing winds, complicating control efforts. Swarming behavior can make outdoor activities unpleasant or intolerable, and can affect livestock production. During the 18th century, the "Golubatz fly" (Simulium colombaschense) was a notorious pest in central Europe.[8] Even non-biting clouds of black flies, whether composed of males or of species that do not feed on humans or do not require a blood meal before egg laying, can form a nuisance by swarming into orifices. Bites are shallow and accomplished by first stretching the skin using teeth ...

Introduction: In a global context of increasing demand for health care and the greater demand on the quality of care, our health systems are being challenged to maintain high quality standards. In order to meet these expectations, it is necessary to apply increasingly efficient management models that safeguard and improve the users perception of the attention received.. Limited public or private resources in health institutions urge us to seek their optimization by implementing more effective alternative modus operandi. By incorporating technological advances in the sector, particularly through new communication systems, we are given an opportunity to substantially alter doctor-patient or administration-patient relations whilst promoting co responsibility in the health process.. With these premises, and a clear commitment to the patient, a project is born focused on the outpatient area of the Hospital Sant Joan de Deu de Martorell in Barcelona. The aim is to simplify the highly complex flow of ...

Cholinesterase (ChE) activity was used as a biomarker for assessing exposure of common carp (Cyprinus carpio) to organophosphate and carbamate insecticides from irrigated agricultural waters. Carp were collected from a lake (Royal Lake) that receives most of its water from irrigation return flows and from a reference lake (Billy Clapp Lake) outside of the irrigation system. Results indicated that the mean whole-brain ChE activity of carp from Royal Lake (3.47 μmol/min/g tissue) was 34.2% less than that of carp from Billy Clapp Lake (5.27 μmol/min/g tissue) (p = 0.003). The depressed ChE activity in brain tissue of Royal Lake carp was in response to ChE-inhibiting insecticides detected in water samples in the weeks prior to tissue sampling; the most frequently detected insecticides included chlorpyrifos, azinphos-methyl, carbaryl, and ethoprop. Neither sex nor size appears to be a covariable in the analysis; ChE activity was not correlated with fish length or weight...
Background: Gastric resections for carcinoma are common, but gastric carcinoma in South Africa, and particularly within the Western Cape province, has not been well documented. Method: The objective of the study was to immunohistochemically evaluate HER2/neu overexpression, determine aberrations in β-catenin and epithelial-cadherin (E-cadherin) expression, and correlate these findings with gastric carcinoma subtypes. Results: Ninety-seven gastric adenocarcinoma resections were morphologically categorised as intestinal-, diffuse- or mixed-type adenocarcinomas, and immunohistochemically stained for β-catenin, E-cadherin (extracellular and cytoplasmic domains) and HER2/neu. The results of staining were compared between the subtypes for statistically significant differences. All 97 cases were confirmed as gastric adenocarcinomas, with 39 (40%) intestinal-type, 51 (53%) diffuse-type, and 7 (7%) mixed-type tumours identified. Patient ages ranged from 18-84 years. HER2/neu was overexpressed in 12 (12%)

The biological mechanism for the thinning is not entirely known, but it is believed that p,p'-DDE impairs the shell gland's ability to excrete calcium carbonate onto the developing egg.[7][9][10][11][12] Multiple mechanisms may be at work, or different mechanisms may operate in different species.[7] Some studies have shown that although DDE levels have fallen dramatically, eggshell thickness remains 10-12 percent thinner than before DDT was first used.[13]. Some studies have indicated that DDE is an endocrine disruptor[14] and contributes to breast cancer, but more recent studies provide strong evidence that there is no relationship between DDE exposure and breast cancer.[15] What is more clear is that DDE is a weak androgen receptor antagonist and can produce male genital tract abnormalities.[16][17]. Animal studies show that organochlorine pesticides-such as DDE-are neurotoxic, cause oxidative stress, and damage the brain's dopaminergic system.[18]. ...
... (DDD) is an organochlorine insecticide that is slightly irritating to the skin.[1] DDD is a metabolite of DDT.[2] DDD is colorless and crystalline;[3] it is closely related chemically and is similar in properties to DDT, but it is considered to be less toxic to animals than DDT.[4] The molecular formula for DDD is (ClC6H4)2CHCHCl2 or C14H10Cl4, whereas the formula for DDT is (ClC6H4)2CHCCl3 or C14H9Cl5. DDD is in the "Group B2" classification, meaning that it is a probable human carcinogen. This is based on an increased incidence of lung tumors in male and female mice, liver tumors in male mice, and thyroid tumors in male rats. Further basis is that DDD is so similar to and is a metabolite of DDT, another probable human carcinogen.[2] DDD is no longer registered for agricultural use in the United States, but the general population continues to be exposed to it due to its long persistence time. The primary source of exposure is oral ingestion of food.[5] 1946 is the ...
... is a widely used, broad-spectrum benzimidazole fungicide and a metabolite of benomyl. It is also employed as a casting worm control agent in amenity turf situations such as golf greens, tennis courts etc. and in some countries is licensed for that use only.[2] The fungicide is used to control plant diseases in cereals and fruits, including citrus, bananas, strawberries, pineapples, and pomes.[3] It is also controversially used in Queensland, Australia on macadamia plantations.[4] A 4.7% solution of carbendazim hydrochloride, sold as Eertavas, is marketed as a treatment for Dutch elm disease. Studies have found high doses of carbendazim cause infertility and destroy the testicles of laboratory animals.[5][6] Maximum pesticide residue limits (MRLs) have reduced since discovering its harmful effects. The MRLs for fresh produce in the EU are now between 0.1 and 0.7 mg/kg with the exception of loquat, which is 2 mg/kg.[7] The limits for more commonly consumed citrus and pome fruits are ...
While botulinum toxin is generally considered safe in a clinical setting, there can be serious side effects from its use. The use of botulinum toxin A in cerebral palsy children is safe in the upper and lower limb muscles.[5][6] Most commonly, botulinum toxin can be injected into the wrong muscle group or with time spread from the injection site, causing temporary paralysis of unintended muscles. Side effects from cosmetic use generally result from unintended paralysis of facial muscles. These include partial facial paralysis, muscle weakness, and trouble swallowing. Side effects are not limited to direct paralysis however, and can also include headaches, flu-like symptoms, and allergic reactions.[41] Just as cosmetic treatments only last a number of months, paralysis side-effects can have the same durations.[citation needed] At least in some cases, these effects are reported to dissipate in the weeks after treatment.[citation needed] Bruising at the site of injection is not a side effect of the ...
... has little systemic absorption, and is considered safe for topical use in adults and children over the age of 2 months. The FDA has assigned it as pregnancy category B. Animal studies have shown no effects on fertility or teratogenicity, but studies in humans have not been performed. The excretion of permethrin in breastmilk is unknown, and breastfeeding is recommended to be temporarily discontinued during treatment.[11] According to the Connecticut Department of Public Health, permethrin "has low mammalian toxicity, is poorly absorbed through the skin, and is rapidly inactivated by the body. Skin reactions have been uncommon."[14] Excessive exposure to permethrin can cause nausea, headache, muscle weakness, excessive salivation, shortness of breath, and seizures. Worker exposure to the chemical can be monitored by measurement of the urinary metabolites, while severe overdose may be confirmed by measurement of permethrin in serum or blood plasma.[15] Permethrin does not present any ...
Human exposure to methoxychlor occurs via air, soil, and water,[7] primarily in people who work with the substance or who are exposed to air, soil, or water that has been contaminated. It is unknown how quickly and efficiently the substance is absorbed by humans who have been exposed to contaminated air or via skin contact.[7] In animal models, high doses can lead to neurotoxicity.[7] Some methoxychlor's metabolites have estrogenic effects in adult and developing animals before and after birth.[7] One studied metabolite is 2,2-bis(p-hydroxyphenyl)-1,1,1-trichloroethane (HPTE) which shows reproductive toxicity in an animal model by reducing testosterone biosynthesis.[8][9] Such effects adversely affect both the male and female reproductive systems. It is expected that this "could occur in humans" but has not been proven.[7] While one study has linked methoxychlor to the development of leukemia in humans, most studies in animals and humans have been negative, thus the EPA has determined that it is ...
GV (IUPAC name: 2-(Dimethylamino)ethyl N,N-dimethylphosphoramidofluoridate) is an organophosphate nerve agent. GV is a part of a new series of nerve agents with properties similar to both the "G-series" and "V-series". It is a potent acetylcholinesterase inhibitor with properties similar to other nerve agents, being a highly poisonous vapour. Treatment for poisoning with GV involves drugs such as atropine, benactyzine, obidoxime, and HI-6.[1][2] ...
The four-membered ring in α-pinene 1 makes it a reactive hydrocarbon, prone to skeletal rearrangements such as the Wagner-Meerwein rearrangement. For example, attempts to perform hydration or hydrogen halide addition with the alkene functionality typically lead to rearranged products. With concentrated sulfuric acid and ethanol the major products are terpineol 2 and its ethyl ether 3, while glacial acetic acid gives the corresponding acetate ester 4. With dilute acids, terpin hydrate 5 becomes the major product. With one molar equivalent of anhydrous HCl, the simple addition product 6a can be formed at low temperature in the presence of ether, but it is very unstable. At normal temperatures, or if no ether is present, the major product is bornyl chloride 6b, along with a small amount of fenchyl chloride 6c.[5] For many years 6b (also called "artificial camphor") was referred to as "pinene hydrochloride", until it was confirmed as identical with bornyl chloride made from camphene. If more HCl is ...

... is extracted from Huperzia serrata.[2] It is a reversible acetylcholinesterase inhibitor[6][7][8][9] and NMDA receptor antagonist[10] that crosses the blood-brain barrier.[11] Acetylcholinesterase is an enzyme that catalyzes the breakdown of the neurotransmitter acetylcholine and of some other choline esters that function as neurotransmitters. The structure of the complex of huperzine A with acetylcholinesterase has been determined by X-ray crystallography (PDB code: 1VOT; see the 3D structure).[12] For some years, huperzine A has been investigated as a possible treatment for diseases characterized by neurodegeneration, particularly Alzheimer's disease.[2][13] A 2013 meta-analysis found that huperzine A may be efficacious in improving cognitive function, global clinical status, and activities of daily living for individuals with Alzheimer's disease. However, due to the poor size and quality of the clinical trials reviewed, huperzine A should not be recommended as a treatment for ...
... is a poisonous diterpenoid found in the South American plant Ryania speciosa (Salicaceae). It was originally used as an insecticide.. The compound has extremely high affinity to the open-form ryanodine receptor, a group of calcium channels found in skeletal muscle, smooth muscle, and heart muscle cells.[1] It binds with such high affinity to the receptor that it was used as a label for the first purification of that class of ion channels and gave its name to it.. At nanomolar concentrations, ryanodine locks the receptor in a half-open state, whereas it fully closes them at micromolar concentration. The effect of the nanomolar-level binding is that ryanodine causes release of calcium from calcium stores as the sarcoplasmic reticulum in the cytoplasm, leading to massive muscular contractions. The effect of micromolar-level binding is paralysis. This is true for both mammals and insects.. ...
... is very toxic to cats which cannot tolerate the therapeutic doses for dogs.[7] This is associated with UGT1A6 deficiency in cats, the enzyme responsible for metabolizing cypermethrin. As a consequence, cypermethrin remains much longer in the cat's organs than in dogs or other mammals and can be fatal in large doses. In male rats cypermethrin was shown to exhibit a toxic effect on the reproductive system. After 15 days of continual dosing, both androgen receptor levels and serum testosterone levels were significantly reduced. These data suggested that cypermethrin can induce impairments of the structure of seminiferous tubules and spermatogenesis in male rats at high doses.[8] Long-term exposure to cypermethrin during adulthood is found to induce dopaminergic neurodegeneration in rats, and postnatal exposure enhances the susceptibility of animals to dopaminergic neurodegeneration if rechallenged during adulthood.[9] If exposed to cypermethrin during pregnancy, rats give birth to ...
Before DDT, malaria was successfully eliminated or curtailed in several tropical areas by removing or poisoning mosquito breeding grounds and larva habitats, for example by eliminating standing water. These methods have seen little application in Africa for more than half a century.[137] According to CDC, such methods are not practical in Africa because "Anopheles gambiae, one of the primary vectors of malaria in Africa, breeds in numerous small pools of water that form due to rainfall ... It is difficult, if not impossible, to predict when and where the breeding sites will form, and to find and treat them before the adults emerge."[138] The relative effectiveness of IRS versus other malaria control techniques (e.g. bednets or prompt access to anti-malarial drugs) varies and is dependent on local conditions.[34] A WHO study released in January 2008 found that mass distribution of insecticide-treated mosquito nets and artemisinin-based drugs cut malaria deaths in half in malaria-burdened Rwanda ...
