Scope: This standard specifies a gas chromatographic method for the determination of organophosphorus pesticides in solid waste and its leachate. This standard is applicable to the determination of 12 organophosphorus pesticides in solid waste and its leachate, including profenofos, phorate, dimethoate, diazinon, acetate, isopyrazine, methyl parathion, dimethoate Lathion, chlorpyrifos, parathion, Daofengsan and ethion. If verified, this standard can also be applied to the determination of other organophosphorus pesticides. When measuring solid waste, when the sampling amount is 10.0g, the method detection limit of 12 organophosphorus pesticides is 0.6~1.2μg/kg, and the lower limit of determination is 2.4~4.8μg/kg. When measuring solid waste leachate, when the sampling volume is 100ml, the method detection limit of 12 organophosphorus pesticides is 0.2~0.3μg/L, and the lower limit of determination is 0.8~1.2μg/L. See Appendix A for details.
