Biomarkers of pesticide exposure used to assess pesticide exposure include: (1) cholinesterase enzyme activities including acetylcholinesterase (AChE) and butyrylcholinesterase (BChE) for assessing the exposure to organophosphate and carbamate containing pesticides; (2) dialkyl phosphate metabolites (DAPs), nonspecific for organophosphates [4-7]; (3) urinary 3-phenoxybenzoic acid (3-PBA), a major metabolite of synthetic pyrethroid[8, 9]; and (4) urinary glyphosate [10].

By immobilizing the cholinesterase enzyme on the carrier in the detection device, the reaction makes it possible to detect the paralytic nerve warfare agents in the vapor-air mixture and also in water.
Organophosphates (contained in regulated agricultural insecticides and ingested to attempt suicide) cause harm by inhibiting function of the cholinesterase enzyme.
