NIOSH 5514


Demeton is a phosphorothioate insecticide, mainly obsolete due to its relatively high toxicity to humans. The chemical structure of demeton is also closely related to military nerve agents. This test method uses gas chromatography and phosophorus FPD techniques to monitor Demeton. This revises Method S280. Demeton is a cholinesterase inhibitor and readily absorbed through the skin; baseline and routine red blood cell cholinesterase monitoring is recommended.

Analysis Type (Application Method): Gas chromatography, phosphorus FPD
