- Scope
- This standard specifies the use of isotope dilution high-resolution gas chromatography-high-resolution mass spectrometry for the detection of 2,3,7,8-chlorodioxins and tetrachloro-octachloro-substituted polychlorinated dibenzo-p-dioxins. Methods for the qualitative and quantitative analysis of polychlorinated dibenzofurans and polychlorinated dibenzofurans. This standard is applicable to dioxin analysis in national regional soil background, farmland soil environment, soil environmental assessment of construction projects, soil pollution accidents, and environmental surveys of rivers, lakes, and ocean sediments.
