Routine gas chromatographic determination of dialkylphosphate metabolites in the urine of workers occupationally exposed to organophosphorus insecticides.
A routine gas chromatographic (GC) method is described for the analysis of dialkylphosphate metabolites in the urine of workers occupationally exposed to organophosphorus insecticides. The procedure involves derivatizing a freeze-dried urine sample with pentafluorobenzyl bromide and then determining the metabolites using dual capillary column GC with flame photometric detection.
