Scope

This standard specifies the isotope dilution/high-resolution gas chromatography-low-resolution mass spectrometry method for the determination of polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans in soil and sediments. This standard is applicable to the preliminary screening of dioxin-like substances in soil and sediments, mainly including high-resolution gas chromatography/low-resolution mass spectrometry of polychlorinated dibenzo-p-dioxins and dibenzofurans from tetrachlorine to octachlorine. Combined measurement method. It is recommended to use high-resolution mass spectrometry methods such as HJ 77.4 for accident arbitration, construction project evaluation and acceptance. The detection limit of this standard method varies with factors such as the sensitivity of the instrument, the concentration of dioxin in the sample, and the level of interference. When the soil sampling amount is 20 g, the detection limit of 2,3,7,8-T4CDD should be lower than 1.0 ng/kg, see Table 1.
