Chemistry, Metabolism and Neurotoxicity of Organophosphorus Insecticides: A Review [PDF]

Nature Environment and Pollution Technology, 2023
Organophosphorus compounds (OPs) are phosphoric acid derivatives represented by the formula (R2XP=O/S), R as organic groups; however, they need not contain a direct carbon-phosphorus bond.
