This European Standard specifies a method for quantitative determination of seven selected polychlorinated biphenyls (28, 52, 101, 118, 138, 153 and 180) in soil, sludge, sediments, suspended solids and waste using GC/MS and GC/ECD (See also annex A)The limit of detection is dependent on the determinants, the equipment used, the quality of chemicals used for the extraction of the soil sample and the clean up of the extract.Under the conditions specified in this standard limits of detection of 1 µg/kg (expressed as dry matter) may be achieved.Waste, sludge and soil may differ in properties and also in the expected contamination levels of PCBs and presence of interfering substances. These differences make it impossible to describe one general procedure. This standard contains decision tables based on the properties of the sample and the extraction and clean up procedure to be used. This method is performance based. It is permitted to modify the method to overcome interferences notforeseen in this standard, provided that all performance criteria in this method are met.
