개요

Carbaryl is a colourless to light tan or white or grey solid crystal depending on the purity of the compound. The crystals are essentially odourless and stable to heat, light, and acids but are not stable under alkaline conditions. It is non-corrosive to metals, packaging materials, and application equipment. Carbaryl is classified as a general use pesticide (GUP). It is sparingly soluble in water, but soluble in dimethylformamide, dimethyl sulfoxide, acetone, cyclohexanone, isopropanol, and xylene. Carbaryl is a wide-spectrum carbamate insecticide, which controls over 100 species of insects on citrus, fruit, cotton, forests, lawns, nuts, ornamentals, shade trees, and other crops, as well as on poultry, livestock, and pets. It is also used as a molluscicide and an acaricide. Carbaryl works whether it is ingested into the stomach of the pest or absorbed through direct contact. It is available as bait, dusts, wettable powders, granules, dispersions, and suspensions.

물리적 성질

White to light tan crystals with a bleach-like type odor. At 40 °C, the average odor threshold concentration and the lowest concentration at which an odor was detected were 280 and 37 μg/L, respectively. At 25 °C, the average taste threshold concentration and the lowest concentration at which a taste was detected were 140 and 44 μg/L, respectively (Young et al., 1996).

용도

Carbaryl is a pesticide, an insecticide of the carbamate group. It induced sensitization in a farmer.

Indications

Carbaryl (Sevin), a cholinesterase inhibitor insecticide, is used as a pediculicide in the form of a shampoo. This product has an objectionable odor, but has some ovicidal activity. It is an effective medication available in England and some other countries but not in the United States.

정의

ChEBI: A carbamate ester obtained by the formal condensation of 1-naphthol with methylcarbamic acid.

일반 설명

A white crystalline solid. Insoluble in water. Combustible, although difficult to ignite. Toxic by inhalation (dust, etc.). Produces toxic oxides of nitrogen during combustion.

공기와 물의 반응

Slightly soluble in water.

반응 프로필

Carbaryl is a carbamate ester. Carbamates are chemically similar to, but more reactive than amides. Like amides they form polymers such as polyurethane resins. Carbamates are incompatible with strong acids and bases, and especially incompatible with strong reducing agents such as hydrides. Flammable gaseous hydrogen is produced by the combination of active metals or nitrides with carbamates. Strongly oxidizing acids, peroxides, and hydroperoxides are incompatible with carbamates. Carbaryl is unstable in an alkaline media. . Carbaryl is incompatible with the following: Strong oxidizers, strongly alkaline pesticides .

위험도

Toxic by ingestion, inhalation, and skin absorption; irritant. A reversible cholinesterase inhibitor. Use may be restricted. Questionable car- cinogen. Male reproductive and embryo damage.

건강위험

Acute oral toxicity — moderate in rats; dermal toxicity low to very low; oral LD50 value(rats); 250 mg/kg, skin LD50 value (rats);4000 mg/kg; toxic symptoms in humans —nausea, vomiting, diarrhea, abdominal cramps,miosis, lachrimation, excessive salivation,nasal discharge, sweating, cyanosis, muscletwitching, convulsions, and coma; acetylcholinesterase inhibitor; exposure limit: TLVTWA 5 mg/m³ (ACGIH, OSHA, and MSHA).
The poisoning effects from carbaryl takeplace very quickly, but lasts only for a shorttime. It is readily hydrolyzed to 1-naphtholwhich is excreted. Although its toxicity inhumans is relatively low, the compound canproduce strong effect on bees and aquaticspecies even in small quantities.

화재위험

Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes. Containers may explode when heated. Runoff may pollute waterways.

농업용

Insecticide, Nematicide, Plant growth regulator: Carbaryl is one of the most widely used insecticides in agriculture, professional turf management and ornamental production, as well as in residential pet, lawn, and garden markets. It controls over 100 species of insects that infect citrus, cotton, nuts, and forest and ornaments trees, as well as poultry and livestock. Carbaryl also is used as a mosquito adulticide. It is available in a variety of formulations bait, dust, wettable powders, granules, dispersions and suspensions. Washington State, for example, has a Special Local Needs registration to control burrowing shrimp in oyster beds. A U.S. EPA restricted Use Pesticide (RUP). Banned for use in EU countries.

신진 대사 경로

The metabolism of carbaryl has been extensively reviewed many times and so original research papers are not generally quoted. Pathways for carbaryl include hydroxylation of the aromatic ring and the methyl group, carbamate ester hydrolysis and conjugation. The metabolism of carbaryl has been extensively reviewed by Schlagbauer and Schlagbauer (1972), Fukuto (1972), Kuhr and Dorough (1976), Mount and Oehme (1981) and by the WHO (1994). Metabolism in man was reviewed by Hutson (1981) and in economic animals by Akhtar (1985).

신진 대사

Carbaryl undergoes hydrolysis and ring oxidation in soils. The major metabolite in a number of studies was 1-naphthol. Metabolites also included 4-hydroxycarbaryl and 5-hydroxycarbaryl. In mammals, the major metabolite is 1-naphthol. This is eliminated in urine and feces, together with the glucuronic acid conjugate. Aromatic ring hydroxylation at the 3-, 4-, 5-, or 6- positions also occurs as does hydroxylation at the N-methyl group.
