Description / Abstract:
This International Standard specifies a method for quantitative
determination of seven selected polychlorinated biphenyls (PCB28,
PCB52, PCB101, PCB118, PCB138, PCB153, and PCB180) in sludge,
treated biowaste, and soil using GC-MS and GC-ECD.
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 International Standard, a
limit of application of 1 μg/kg (expressed as dry matter) can be
achieved.
Sludge and treated biowaste can 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 International Standard
contains decision tables based on the properties of the sample and
the extraction and clean-up procedure to be used.
