Organophosphate toxicity and occupational exposure.
The ubiquitous organophosphates present a continuing health hazard in agriculture, public health eradication programmes and as chemical warfare agents. Despite significant progress in understanding the potential mechanisms of toxicity far beyond the commonly accepted mechanism of cholinesterase inhibition in intentional exposures, the precise health effects following occupational exposures are ...
متن کاملImpact of Atrazine on Organophosphate Insecticide Toxicity
Acute toxicity of selected organophosphorus insecticides (OPs; chlorpyrifos, methyl parathion, diazinon, and malathion) was determined for individual OPs and binary combinations of the OPs with atrazine to larvae of the midge Chironomus tentans. Atrazine individually was not acutely toxic even at high concentrations (10,000 mg/L); however, the presence of atrazine at much lower concentrations (...
متن کاملOrganophosphate nerve agent toxicity in Hydra attenuata.
The toxicity for analogues of sarin (GB), soman (GD), and VX was evaluated using Hydra attenuata as a model organism. The organophosphate nerve agent analogue simulants used in this investigation included the following: isopropyl p-nitrophenyl methylphosphonate (for GB); pinacolyl p-nitrophenyl methylphosphonate (for GD); and diisopropyl S-(2-diisopropylaminoethyl)phosphorothioate, diethyl S-(2...
متن کاملORGANOPHOSPHATE-INDUCED CHRONIC TOXICITY IN OCCUPATIONALLY EXPOSED WORKERS
Organophosphate chronic toxicity has been evaluated in this study. Biological screening for organophosphate insecticide-exposed workers is mostly recommended for mixers, loaders, formulators and spraymen. We have studied 17 occupationally exposed persons to pesticides. Using Ellman's colorimetric method, their plasma cholinesterase activities have been measured. Results show that the appear...
متن کاملSublethal toxicity of organophosphate, diazinon on some organs of great sturgeon (Huso huso)
Sublethal toxicity effects of diazinon on the structure of some organs of great sturgeon ( Huso huso ) were investigated. Diazinon was applied at a sublethal concentration of 1.5 mg L -1 at 22±1 ºC for nine weeks as a constant bath. Tissues of liver, kidney and gills were sampled and examined histopathologically after 1, 14, 28, 42 and 63 days post exposure to the...
