에티온 화학적 특성, 용도, 생산

• 화학적 성질

  ethion is an odorless amber liquid. It is very sparingly soluble in water, but soluble in most organic solvents. Ethion undergoes decomposition on heating or on burning and produces toxic and corrosive fumes, including phosphorus oxides and sulfur oxides. It is used for the control of crop pests and household insects. These include, but are not limited to, aphids, mite, sticks, scales, thrips, leaf hoppers, maggots, leaf-feeding insects, foliar-feeding larvae, and house fl ies. It may be used on a wide variety of food, fi ber, and ornamental crops, including greenhouse crops, lawns, and turf. Ethion is often used on citrus and apples. It is mixed with oil and sprayed on dormant trees to kill eggs and scales. Occupational workers and the general public are exposed to ethion while working in industries that manufacture ethion and when eating raw fruits or vegetables that have been treated with ethion. There are no residential uses for ethion.

• 용도

  Ethion is used to control mites and sucking insects, larval Lepidoptera and soil pests in a wide range of crops and in turf. An additional use is as an ectoparasiticide to control cattle ticks.

• 정의

  ChEBI: An organic thiophosphate that is S,S'-methanediyl bis[dihydrogen (phosphorodithioate)] in which all the hydroxy groups have been converted to their corresponding ethyl esters respectively. Ethion is an organophosphate insecticide with inhibitory activity t wards the enzyme acetylcholinesterase ( EC 3.1.1.7).

• 일반 설명

  Technical ethion is an odourless amber liquid. It is very sparingly soluble in water but soluble in most of the organic solvents. Ethion undergoes decomposition on heating or on burning and produces toxic and corrosive fumes including phosphorus oxides and sulphur oxides. It is used for the control of crop pests and household insects. It may be used on a wide variety of food, fibre, and ornamental crops, including greenhouse crops, lawns, and turf.

• 반응 프로필

  Organothiophosphates, such as ETHION, 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.

• 위험도

  Cholinesterase inhibitor, use may be restricted. Questionable carcinogen.

• 건강위험

  ETHION is very toxic; the probable oral lethal dose for humans is 50-500 mg/kg, which is between one teaspoonful and one ounce for a 150-lb person.

• 화재위험

  Shock can shatter the container, releasing the contents. Fire may produce irritating or poisonous gases. Decomposes above 302F. When heated to decomposition ETHION emits highly toxic fumes of oxides of sulfur and phosphorus. Hydrolyzed by acids and alkalies. Slowly oxidized in air.

• 농업용

  : Insecticide, Acaricide: Not approved for use in EU countries. Not registered for use in the U.S. There are 33 global suppliers. Ethion is an organophosphate pesticide used to kill aphids, mites, scales, thrips, leafhoppers, maggots, and foliar feeding larvae. It may be used on a wide variety of food, fiber, and ornamental crops, including greenhouse crops, lawns, and turf. Ethion is a preharvest topical insecticide used primarily for spraying on citrus fruits, deciduous fruits, apples, nuts and cotton. It is also used as a cattle dip for ticks and as a treatment for buffalo flies. It is mixed with oil and sprayed on dormant trees to kill eggs and scales. It is available in dust, emulsifiable concentrate, emulsifiable solution, granular, and wettable powder formulations.

• Safety Profile

  Poison by ingestion, skin contact, and intraperitoneal routes. Human systemic effects by ingestion: flaccid paralysis without anesthesia, motor activity changes, fever, and inhibition of cholinesterase. When heated to decomposition it emits highly toxic fumes of SOx and POx. See also PARATHION

• 잠재적 노출

  An organothiophosphate. A potential danger to those involved in the manufacture, formulation and application of this insecticide and acaricide. Ethion is a preharvest topical insecticide used primarily on citrus fruits, deciduous fruits, nuts, and cotton. It is also used as a cattle dip for ticks and as a treatment for buffalo flies

• 환경귀착

  Biological. Ethion degraded in lagoonal sediments obtained at various sites in the Indian River between Cape Kennedy and Vero Beach, FL. In 14 sediment samples enriched with ethion, 8 exhibited iron sulfide (precursor hydrogen sulfide) production following 20 days of incubation at room temperature. The bacteria responsible for the degradation of ethion, a reducing agent, was tentatively identified as Clostridium (Sherman et al., 1974).
  Soil. The half-lives of ethion in an organic soil varied from 16 to 49 weeks; however, repeated applications each spring resulted in increased residues of unreacted ethion (Chapman et al., 1984).
  Photolytic. Ethion in hexane did not exhibit absorption at UV wavelengths >260 nm (Gore et al., 1971). Chemical/Physical. Emits toxic fumes of phosphorus and sulfur oxides when heated to decomposition (Sax and Lewis, 1987; Lewis, 1990).
  The hydrolysis half-lives of ethion in a sterile 1% ethanol/water solution at 25°C and pH values of 4.5, 5.0, 6.0, 7.0 and 8.0 were 99, 63, 58, 24 and 8.4 weeks, respectively (Chapman and Cole, 1982).

• 신진 대사 경로

  Ethion is principally degraded in animals via hydrolysis which results in P-S and C-S bond cleavage to give O,O-diethyl phosphorothioate and O,O-diethyl phosphorodithioate respectively. It is also oxidatively desulfurated to its mono and dioxon forms.

• 신진 대사

  The main biodegradation routes of ethion in animals are cleavage of the P?S and C?S linkages to give O,O-diethyl hydrogen phosphorothioate and O,O-diethyl hydrogen phosphorodithioate, respectively. Oxidative desulfuration to its mono- and dioxons also occurs.

• 비 호환성

  Decomposes violently when heated above 150℃. Mixtures with magnesium may be explosive. Contact with oxidizers may cause the release of phosphorous oxides. Contact with strong reducing agents, such as hydrides; may cause the formation of flammable and toxic phosphine gas

• 폐기물 처리

  Do not empty into drains or sewage system. Small amounts can be burned with alkali. For larger amounts, the suggested method is incineration with added solvent in furnace equipped with afterburner and alkali scrubber. 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.
