Abstract

Polychlorinated biphenyls (PCBs) and polybrominated biphenyl ethers (PBDEs) were determined in environmental samples collected from Ny-Ålesund and London Island, Svalbard, the Arctic. Total PCB concentrations (∑25PCBs) varied from 0.57 to 2.52ngg-1 dry weight (dw) in soil, 0.30 to 1.16ngg-1dw in plants and 0.56 to 0.98ngg-1dw in reindeer dung. The non-Aroclor congener of CB-11 was predominant in most samples compared to other congeners, accounting for 16.0±9.8% to the ∑25PCBs. The ∑13PBDEs concentrations were 1.7-416, 36.7-495 and 28.1-104pgg-1dw in soil, plants and reindeer dung, respectively. The signature of enantioselective biotransformation was observed in all samples for chiral CB-95, whereas in parts of samples for other chiral PCBs. Bioaccumulation factors (BAFs) in six plant species varied within individual contaminant congeners and plant species, with BAFs less than 1 for ∑PCBs and higher than 1 for ∑PBDEs. BAF values decreased with increasing soil concentrations, suggesting that high background levels in soil restricted the accumulation of these contaminants by plants.
