Описание
Cases of sensitization to dichlorvos have been seen in chrysanthem growers, horticulturists, technicians and in a chemist.Химические свойства
Dichlorvos is available as an oily colourless to amber liquid with an aromatic chemical odour. It is slightly soluble in water but soluble in kerosene, ethanol, chloroform, and acetone and miscible with alcohol, aromatic and chlorinated hydrocarbon solvents, aerosol propellants, and other non-polar solvents. Dichlorvos in contact with strong acids or alkalis undergoes decomposition and releases hazardous products toxic gases and vapours such as phosphorus, chlorinated oxides, and carbon monoxide.Физические свойства
Colorless to yellow liquid with a mild aromatic odorИспользование
Dichlorvos is used for the control of household and public health insect pests and the control of sucking and chewing pests in a wide range of crops. It is used as a veterinary anthelmintic, as an ectoparasiticide on fish and domestic pets and a vapour phase domestic insecticide as well for the control of phorid and sciarid flies in mushroom compost.Определение
ChEBI: An alkenyl phosphate that is the 2,2-dichloroethenyl ester of dimethyl phosphate.Общее описание
An aromatic colorless to amber liquid absorbed in a dry carrier. Denser than water and slightly soluble in water. Toxic by inhalation, skin absorption, absorption, or ingestion. Flash point 175°F or higher. When heated to high temperatures may emit toxic chloride fumes and phosgene gas. Used as a pesticide.Реакции воздуха и воды
Slightly soluble in water.Профиль реактивности
DICHLORVOS MIXTURE is incompatible with strong acids and bases. Dichlorvos is slowly hydrolyzed in acidic media and rapidly hydrolyzed by alkalis. Dichlorvos is corrosive to iron and mild steel. . Organophosphates are susceptible to formation of highly toxic and flammable phosphine gas in the presence of strong reducing agents such as hydrides. Partial oxidation by oxidizing agents may result in the release of toxic phosphorus oxides.Угроза здоровью
Exposures to dichlorvos through all routes, namely, oral, dermal, and respiratory, cause adverse effects to species of laboratory animals, such as rats, mice, and rabbits. The symptoms of poisoning include perspiration, nausea, salivation, vomiting, diarrhea, drowsiness, fatigue, headache, and in severe cases, tremors, ataxia, convulsions, and coma.Humans exposed to dichlorvos show many symptoms of poisoning that include, but are not limited to, irritability, confusion, headache, speech diffi culties, sweating, blurred vision, drowsiness or insomnia, numbness, tingling sensations, incoordination, tremor, abdominal cramps, diffi culty in breathing or respiratory depression and slow heart beat, impaired memory concentration, disorientation, and severe depressions.
Пожароопасность
Combustible material: may burn but does not ignite readily. Containers may explode when heated. Runoff may pollute waterways. Substance may be transported in a molten form.Сельскохозяйственное использование
Insecticide, Acaricide, Nematicide: Dichlorvos is used for insect control in food-storage areas, green-houses, and barns, and control of insects on livestock. It is not generally used on outdoor crops. Dichlorvos is sometimes used for insect control in workplaces and in the home. Dichlorvos used in pest control is diluted with other chemicals and used as a spray. It can also be incorporated into plastic that slowly releases the chemical. Veterinarians use it to control parasites on pets. Dichlorvos is effective against mushroom flies, aphids, spider mites, caterpillars, thrips, and white flies in greenhouse, outdoor fruit, and vegetable crops. It is used to treat a variety of parasitic worm infections in dogs, livestock, and humans. Dichlorvos can be fed to livestock to control botfly larvae in the manure. It acts against insects as both a contact and a stomach poison. It is used as a fumigant and has been used to make pet collars and pest strips. It is available as an aerosol and soluble concentrate. Not approved for use in EU countries. A U.S. EPA restricted Use Pesticide (RUP). Dichlorvos also exists as a breakdown product.Торговое название

Cases of sensitization to this organophosphorus compound with several commercial names (Benfos, Brevinyl, Chlorvinphos, DDVP, Equigard, Fly fghte, Nogos, and Unifos) were occupationally seen in chry- santhem growers, horticulturists, technicians, and in a chemist.Профиль безопасности
Confirmed carcinogen with carcinogenic and tumorigenic data. Poison by ingestion, inhalation, skin contact, subcutaneous, intravenous, and intraperitoneal routes. Experimental teratogenic and reproductive effects. Human mutation data reported. A cholinesterase inhibitor, it is used in flea (pest) collars for pets. No neurotoxicity has been observed. It is very rapidly metabolized and excreted. When heated to decomposition it emits very toxic fumes of Cl and POx. See also PARATHION.Возможный контакт
A potential danger to those involved in manufacture, formulation and application of this fumigant insecticide in household, public health and agricultural uses. Used as an insecticide and as an anthelminthic for swine and dogs.Канцерогенность
Two epidemiological studies reporting an association between exposure to dichlorvos resin strips and childhood cancer were reviewed by EPA and found to have biases and confounders that could explain the observed associations. Additional studies that correct for the control of potential biases and problems of exposure determination are needed before an association between dichlorvos and childhood cancer can be established.Метаболический путь
The metabolism of dichlorvos has been extensively studied particularly in mammals. Dichlorvos is rapidly transformed in both environmental and biological situations via a hydrolytic mechanism to yield dimethyl phosphate and dichloroacetaldehyde which is further metabolised to 2,2-dichloroethanol or dechlorinated to glycolic acid. An additional important route in mammals involves demethylation catalysed by glutathione-S-methyl transferase to yield methylglutathione and desmethyldichlorvos.Перевозки

Contact with oxidizers may cause the release of phosphorous oxides. Organophosphates are susceptible to formation of highly toxic and flammable phosphine gas in the presence of strong reducing agents such as hydrideds and active metals. Partial oxidation by oxidizing agents may result in the release of toxic phosphorus oxides Corrosive to iron, mild steel, some forms of plastics, rubber, and coatingsУтилизация отходов
50% hydrolysis is obtained in pure water in 25 minutes @ 70_x0003_°C and in 61.5 days @ 20C. A buffered solution yields 50% hydrolysis (37.5°C) in 301 minutes at pH 8, 462 minutes at pH 7, 620 minutes at pH 5.4. Hydrolysis yields no toxic residues. Incineration in a furnace equipped with an afterburner and alkaline scrubber is recommended as is alkaline hydrolysis followed by soil burial. In accordance with 40CFR165, follow recommendations for the disposal of pesticides and pesticide containers. Must be disposed properly by following package label directions or by contacting your local or federal environmental control agency, or by contacting your regional EPA office.Дихлорвос запасные части и сырье
