HJ 753-2015 (English Version) PDF

Scope: This standard specifies the liquid-liquid extraction or solid-phase extraction/gas chromatography-mass spectrometry method for chlorothalonil and 8 pyrethroid pesticides in water. This standard is applicable to the determination of chlorothalonil and pyrethroid pesticide compounds in surface water, groundwater, industrial wastewater and domestic sewage. When the sampling volume of the liquid-liquid extraction method is 1 L, the detection limit of the method is 0.005 μg/L~0.05 μg/L, and the lower limit of determination is 0.020 μg/L~0.20 μg/L; when the sampling volume of the solid-phase extraction method is 500 ml, The detection limit of the method is 0.005 μg/L~0.08 μg/L, and the lower limit of determination is 0.020 μg/L~0.32 μg/L. See Appendix A for details.
