Scope

This standard specifies the high-resolution gas chromatography-high resolution mass spectrometry method for determining organic chlorine pesticides in ambient air. This standard is applicable to the determination of hexachlorobenzene, α-hexachlorocyclohexane, γ-hexachlorocyclohexane, β-hexachlorocyclohexane, δ-hexachlorocyclohexane, heptachlor, Aldrin, Chlordecone, cis-Oxydichlorodibenzo-p-dioxin, trans-Oxydichlorodibenzo-p-dioxin, trans-Chlordecone, 2,4'-DDE, trans-Nonachlor, cis-Chlordecone, 4,4'-DDE, Dieldrin, 2,4'-DDD, m-DDD, 2,4'-DDT, cis-Nonachlor, 4,4'-DDT, and Methyl parathion (a total of 25 organic chlorine pesticides) in ambient air and particulate matter. See Appendix A. When the sampling volume is 30 m3 (standard conditions) and the concentrated and diluted volume is 20 μL, the detection limit for hexachlorobenzene is 0.9 pg/m3, and the determination limit is 3.6 pg/m3; when the sampling volume is 1200 m3 (standard conditions) and the concentrated and diluted volume is 20 μL, the detection limits for other organic chlorine pesticides except hexachlorobenzene range from 0.006 pg/m3 to 0.03 pg/m3, and the determination limits range from 0.024 pg/m3 to 0.12 pg/m3. See Appendix B for details.
