V-type nerve agents, known as VX, are organophosphate (OP) compounds, and show extremely toxic effects on human and animals by causing cholinergic overstimulation of synapses. The bacterial organophosphorus hydrolase (OPH) has attracted much attention for detoxifying V-type agents through hydrolysis

A case of lethal suicidal intoxication with demeton-S-methyl is reported. Capillary chromatography on wide-bore columns (CP-sil 5, 0.53 mm ID, 1 micron film thickness) was used for the quantitative determinations of this substance in the body fluids and tissues.

We have reported the enzymatic hydrolysis of phosphoro- and phosphonofluoridates and phosphoro- and phosphonothiolates and -thionates by an organophosphorus hydrolase (OPH) from Pseudomonas diminuta. In screening for other microbial sources of nerve gas hydrolyzing enzymes, it would be convenient, indeed

The chemical fate of organophosphorus pesticides (OPs) has been proven to depend strongly on the chemistry of their aquatic environment. In particular, metal ions (and metal oxide surfaces) have been known to play an important role in the hydrolytic fate
