采用同位素稀释高分辨气相色谱-高分辨质谱法(isotope dilution high resolution gas chromatography and high resolution mass spectrometry,ID-HRGC-HRMS)测定土壤样品中二恶英类化合物(polychlorinated dibenzo-p-dioxins and dibenzofurans,PCDD/Fs)的等价毒性当量(toxic equivalent quantity,TEQ).讨论并确定了测定土壤样品中二恶英类化合物2,3,7,8位异构体不确定度的来源并合成了各异构体的相对标准不确定度;在此基础上,计算了3种等价毒性当量因子(toxic equivalent factor,TEF)框架下土壤样品中PCDD/Fs的TEQ浓度及其合成不确定度和扩展不确定度.
採用同位素稀釋高分辨氣相色譜-高分辨質譜法(isotope dilution high resolution gas chromatography and high resolution mass spectrometry,ID-HRGC-HRMS)測定土壤樣品中二噁英類化閤物(polychlorinated dibenzo-p-dioxins and dibenzofurans,PCDD/Fs)的等價毒性噹量(toxic equivalent quantity,TEQ).討論併確定瞭測定土壤樣品中二噁英類化閤物2,3,7,8位異構體不確定度的來源併閤成瞭各異構體的相對標準不確定度;在此基礎上,計算瞭3種等價毒性噹量因子(toxic equivalent factor,TEF)框架下土壤樣品中PCDD/Fs的TEQ濃度及其閤成不確定度和擴展不確定度.
