Effect of four organophosphorus insecticides on microbial activities in soil.
Laboratory tests were conducted with four organophosphorus insecticides, Bay 37289 (O-ethyl O-2,4,5-trichlorophenyl ethylphosphonothioate), diazinon [O,O-diethyl O-(2-isopropyl-4-methyl-6-pyrimidinyl) phosphorothioate], Dursban (O,O-diethyl O-3,5,6-trichloro-2-pyridyl phosphorothioate), and Zinophos (O,O-diethyl O-2-pyrazinyl phosphorothioate), applied to a sandy loam at rates of 10 and 100 mug...
متن کاملPoisoning by organophosphorus insecticides and sensory neuropathy.
OBJECTIVES Poisoning by organophosphate insecticides causes cholinergic toxicity. Organophosphate induced delayed polyneuropathy (OPIDP) is a sensory-motor distal axonopathy which usually occurs after ingestion of large doses of certain organophosphate insecticides and has so far only been reported in patients with preceding cholinergic toxicity. Surprisingly, it was recently reported by other ...
متن کاملComparative degradation of organophosphorus insecticides in soil: specificity of enhanced microbial degradation
Laboratory experiments investigated the comparative degradation of six organophosphorus insecticides in soil as affected by enhanced microbial degradation. The degradation rates and product distributions of chlorpyrifos, fonofos, ethoprop, terbufos, and phorate were not dramatically altered in soils containing microbial populations adapted to rapidly degrade isofenphos. An Arthrobacter sp. isol...
متن کامل[Efficacy of several oximes on organophosphorus poisoning].
Various organophosphorus compounds, particularly those with low acute toxicity levels, such as Fenitrothion (common name; Sumithion), Fenthion (common name; Baycid) and Pyridaphenthion (common name; Ofunack), are widely used as insecticides around the world. PAM (2-Pyridinum aldoxime methiodide), the specific antidote against Parathion, is not very effective against poisoning by these organopho...
متن کاملMechanism of action of organophosphorus and carbamate insecticides.
Organophosphorus and carbamate insecticides are toxic to insects and mammals by virtue of their ability to inactivate the enzyme acetylcholinesterase. This review addresses the mechanism of inhibition of acetylcholinesterase by organophosphorus and carbamate esters, focusing on structural requirements necessary for anticholinesterase activity. The inhibition of acetylcholinesterase by these com...
