Preliminary validation studies on ACF passive sampler for PCDD/Fs and PCBs in water
Hydrophobic pollutants as polychlorinated biphenyls (PCBs), polychlorinated dibenzo-p-dioxins (PCDDs) and dibenzofurans (PCDFs) have frequently been identified in several matrices of aquatic ecosystems.
The knowledge of the actual concentrations of these pollutants is essential for integrated water quality management. Due to their very low, but toxicologically relevant levels in natural waters, direct determination of their concentrations is difficult with common analytical techniques.
