Scope

This standard specifies liquid-liquid extraction or solid-phase extraction/gas chromatography-mass spectrometry for the determination of organochlorine pesticides and chlorobenzenes in water. This standard is applicable to the determination of organochlorine pesticides and chlorobenzenes in surface water, groundwater, domestic sewage, industrial wastewater and seawater. The target substances measured by this method and their method detection limits and lower determination limits are shown in Appendix A.
