Abstract

Although parathion is an organophosphate pesticide being legally applied for the purpose of agriculture and is being manufactured, parathion in the air and urinary p-nitrophenol, a metabolite of parathion, were not analysed in Korea. Air of the parathion manufacturing workplace was sampled by OVS-2 tubes using NIOSH 5600 and spot urine of workers was sampled at the end of shift. Parathion and urinary p-nitrophenol were analysed by GC/MS (5973 MSD connected with Agilent 6890 GC) and the protocol was included in this study. It was found that this protocol should be so sensitive that determining parathion in the air and urinary p-nitrophenol below level of ACGIH TLV and BEI be adequate. Another finding was that total sampling volume of air of NIOSH 5600 of 240 L should be adjusted to be less than 120 L due to breakthrough.
