This International Standard specifies a method for quantitative determination of 17 2,3,7,8-chlorine substituted dibenzo-p-dioxins and dibenzofurans and dioxin-like polychlorinated biphenyls in sludge, treated biowaste, and soil using liquid column chromatographic clean-up methods and GC/HRMS. The analytes to be determined with this International Standard are listed in Table1. Table1Analytes and their abbreviations Substance Abbreviation Tetrachlorodibenzo-p-dioxin TCDD Pentachlorodibenzo-p-dioxin PeCDD Hexachlorodibenzo-p-dioxin HxCDD Heptachlorodibenzo-p-dioxin HpCDD Octachlorodibenzo-p-dioxin OCDD Tetrachlorodibenzofuran TCDF Pentachlorodibenzofuran PeCDF Hexachlorodibenzofuran HxCDF Heptachlorodibenzofuran HpCDF Octachlorodibenzofuran OCDF Polychlorinated biphenyl PCB Trichlorobiphenyl TCB Tetrachlorobiphenyl TeCB Pentachlorobiphenyl PeCB Hexachlorobiphenyl HxCB Heptachlorobiphenyl HpCB Decachlorobiphenyl DecaCB The limit of detection depends on the kind of sample, the congener, the equipment used, and the quality of chemicals used for extraction and clean-up. Under the conditions specified in this International Standard, limits of detection better than 1ng/kg (expressed as dry matter) can be achieved. This method is “performance based??. It is permitted to modify the method if all performance criteria given in this method are met. NOTE In principle, this method can also be applied for sediments, mineral wastes, and for vegetation. It is the responsibility of the user of this International Standard to validate the application for these matrices. For measurement in complex matrices like fly ashes adsorbed on vegetation, it can be necessary to further improve the clean-up. This can also apply to sediments and mineral wastes.
