Resumen:
This part of ISO 16000 describes the extraction, clean-up and analysis of polychlorinated biphenyls (PCBs), polychlorinated dibenzo-p-dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs) from indoor air. Sampling of PCBs, PCDDs/PCDFs is described in ISO 16000-13; it is part of the overall PCB/PCDD/PCDF measurement procedure. The sampling strategy to analyse PCBs, PCDDs/PCDFs and PAHs in indoor air is described in ISO 16000-12. After sampling on a filter and a back-up vapour trap (see DIN ISO 16000-13) the filter and the back-up vapour trap are extracted. The clean-up and the separation into a PCB and a PCDD/PCDF fraction are performed by column chromatography. For the analysis high-resolution gas chromatography combined with high-resolution mass spectrometry (HRGC/HRMS) is employed. Losses during extraction and clean-up are detected and compensated by using isotopically-labelled surrogates as internal extraction standards for quantification, together with recovery standards that are added just before the HRGC/HRMS analysis. The method provides accurate quantitative data for tetra- through deca-PCBs and tetra- through octa-PCDDs/PCDFs. It is capable of detecting 0,2 pg/m3 or lower concentrations of most PCBs and PCDFs/PCDDs with air sampling volumes up to 360 m3 or more in special cases. However, it may not be possible to detect all analytes at 0,2 pg/m3 or lower, especially at lower sampling volumes. Precision under normal conditions can be expected to be ± 25 % or better and uncertainty ± 50 % or better.
