This document specifies methods for quantitative determination of seven selected polychlorinated biphenyls (PCB28, PCB52, PCB101, PCB118, PCB138, PCB153 and PCB180) in soil, sludge, sediment, treated biowaste, and waste using GC-MS and GC-ECD Table 2 Target analytes of this document Target analyte CAS-RN a PCB28 2,4,4'-trichlorobiphenyl 7012 37 5 PCB52 2,2',5,5'-tetrachlorobiphenyl 35693 99 3 PCB101 2,2',4,5,5'-pentachlorobiphenyl 37680 73 2 PCB118 2,3',4,4',5-pentachlorobiphenyl 31508 00 6 PCB138 2,2',3,4,4',5'-hexachlorobiphenyl 35065 28 2 PCB153 2,2',4,4',5,5'-hexachlorobiphenyl 35065 27 1 PCB180 2,2',3,4,4',5,5'-heptachlorobiphenyl 35065 29 3 a CAS-RN Chemical Abstracts Service Registry Number. The limit of detection depends on the determinants, the equipment used, the quality of chemicals used for the extraction of the sample and the clean-up of the extract. Under the conditions specified in this document, lower limit of application from 1 ¼g/kg (expressed as dry matter) for soils, sludge and biowaste to 10 ¼g/kg (expressed as dry matter) for solid waste can be achieved. For some specific samples the limit of 10 ¼g/kg cannot be reached. Sludge, waste and treated biowaste may differ in properties, as well as in the expected contamination levels of PCB and presence of interfering substances. These differences make it impossible to describe one general procedure. This document contains decision tables based on the properties of the sample and the extraction and clean-up procedure to be used. NOTE The analysis of PCB in insulating liquids, petroleum products, used oils and aqueous samples is referred to in EN 61619, EN 12766-1 and ISO 6468 respectively. The method can be applied to the analysis of other PCB congeners not specified in the scope, provided suitability is proven by proper in-house validation experiments.
