This standard 21/30429550 DC BS ISO 13914. Soil, treated biowaste and sludge. Determination of dioxins and furans and dioxin-like polychlorinated biphenyls by gas chromatography with high resolution mass selective detection (HR GC-MS) is classified in these ICS categories:
- 13.080.10 Chemical characteristics of soils
This document 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 document are listed in Table 1.

| 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 document, limits of detection better than 1 ng/kg (expressed as dry matter) can be achieved.
This method is “performance based”. It is allowed to modify the method if all performance criteria given in this method are met.
In principle this method can also be applied for sediments, mineral wastes and for vegetation. It is the responsibility of the user of this document 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.
