Is the SRM for PCDD/F appropriate for PCB measurements ?

Abstract : A previous work carried out between 2000 and 2002 has shown that the use of an XAD 2 sorbent in the case of PCB sampling tends to under-estimate PCB concentrations, specially when PCB concentrations are low (< 100 u.g/m3). The objective of this new study was to compare PCBs sampling efficiencies for several methods, at lower concentrations. First, this study consisted in the comparison of 3 sampling methods: washing bottles filled with heptane, adsorption on XAD 2 (such as used for PCDD/F samplings according to EN 1948) and adsorption on polyurethane foam (PUF). Results have shown that washing bottles filled with heptane are far more efficient than XAD 2 or PUF adsorbtion. In addition, the second objective of the study was to optimize the washing bottles method by comparing several solvents (isooctane, hexane and heptane) and by working at two different temperatures (0°C and -20°C).
