This standard specifies the solid phase extraction-gas chromatography method for the determination of organophosphorus pesticides in water. This standard is applicable to the determination of eight organophosphorus pesticides such as dichlorvos, dimethoate, dimethoate, chlorpyrifos, methyl parathion, malathion, parathion and Daofengsan in surface water, groundwater and drinking water. The detection limits of this method are 1.32ng/L for dichlorvos, 1.81ng/L for dimethoate, 2.79ng/L for dimethoate, 1.17ng/L for chlorpyrifos, 1.21ng/L for methyl parathion, and 1.21ng/L for dimethoate. Lathion is 1.08ng/L, parathion is 1.16ng/L, and Daofengsan is 1.02ng/L.
