The fate of acephate and carbaryl in water
Journal of Environmental Science and Health, Part B, 1979Acephate was resistent to hydrolysis in distilled, buffered water at pH 4.0 to 6.9, but not at pH 8.2, held for 20 days at 20 or 30 degrees C. The maximum conversion to methamidophos was 4.5% of the added acephate at pH 8.2 and 20 degrees C. The persistence of acephate in two natural waters, held at 9 degrees C for up to 42 and 50 days varied: 80% were

Metabolism of carbaryl by rat liver and skin post-mitochondrial fraction has been measured in the presence and absence of cofactors to promote different metabolic pathways. The metabolic capacity was compared with the metabolism of carbaryl during percutaneous absorption in a static skin diffusion system using a variety of receptor fluids. Carbaryl was

Exposure of urban applicators to carbaryl
Archives of Environmental Contamination and Toxicology, 1982Thirty-eight urban volunteers from the Lincoln and Omaha, Nebraska areas were monitored for carbaryl exposure during the summer of 1979. All volunteers were involved in the application of carbaryl incidental to their employment or leisure activities. The investigators made no attempt to affect the method of carbaryl application.

Hydroxylations of Carbaryl by Soil Fungi
Nature, 1972CARBARYL (1-naphthyl N-methylcarbamate) is an important pesticide with a half-life in soil of approximately 1 week. However, the possible formation of detoxication products by microorganisms that persist longer in soil has not been investigated.

Biodegradation of Carbaryl by a Micrococcus Species
Current Microbiology, 2001A bacterium capable of utilizing carbaryl as sole source of carbon was isolated from garden soil and identified as a Micrococcus species. The organism also utilized carbofuran, naphthalene, 1-naphthol, and several other aromatic compounds as growth substrates. The organism degraded carbaryl by hydrolysis to yield 1-naphthol and methylamine.

Abstract The diagnostic value of measuring insecticide levels and cholinesterase activity in carbaryl-poisoned rats was studied. Mature, male rats received 450, 800, or 1200 mg carbaryl/kg orally, and carbaryl residues in liver, heart, and brain and/or cholinesterase (ChE) activity in brain, red blood cells, and plasma of sacrificed, moribund, and ...

Environmental Fate and Toxicology of Carbaryl
2008Carbaryl is an agricultural and garden insecticide that controls a broad spectrum of insects. Although moderately water soluble, it neither vaporizes nor volatilizes readily. However, upon spray application the insecticide is susceptible to drift. It is unstable under alkaline conditions, thus easily hydrolyzed.

Carbaryl is a broad-spectrum insecticide effective against lice, with little toxicity to man. It is available as a lotion (Carylderm) and a shampoo (Carylderm; New Suleo; Derbac). Carbaryl was developed because lice began to show resistance to organochlorine insecticides such as DDT and gamma benzene hexachloride (Quellada; Lorexane). It was introduced
