This method describes the use of EVOLUTE WAX plates and columns to extract a suite of organophosphate pesticide metabolites including dimethylphosphate (DMP), dimethylthiophosphate (DMTP), diethylphosphate (DEP), diethylthiophosphate (DETP), dimethyldithiophosphate (DMDTP) and diethyldithiophosphate (DEDTP) from human urine. The method demonstrates extraction of these small polar metabolites at urine concentrations ranging from 40 ng/mL to 400 ng/mL.
