Description

A modified method for the simultaneous determination of 33 organophosphorus pesticides in agricultural crops was presented. After extraction of samples with acetonitrile, the pesticides are transfered into 20% dichloromethane in benzene, cleaned up by charcoal column chromatography, and then determined simultaneously by the gas liquid chromatography with a flame photometric detector using the column of 4% OV-101 and 10% QF-1. The efficiency of the method was evaluated by analyzing water and 7 kinds of crops fortified with the pesticides. The average recoveries of the pesticides from crops were ranged from 72.0% (fenthion) to 108.0% (tetrachlorvinphos) and those from water were quite satisfactory for all pesticides.
