| 英文摘要 | Polychlorinated biphenyls (PCBs) and polybrominated biphenyl ethers (PBDEs) were determined in environmental samples collected from Ny-Alesund and London Island, Svalbard, the Arctic. Total PCB concentrations (Sigma(25)PCBs) varied from 0.57 to 2.52 ng g(-1) dry weight (dw) in soil, 030 to 1.16 ng g(-1) dw in plants and 0.56 to 0.98 ng g(-1) dw 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 Sigma(25)PCBs. The Sigma 13PBDEs concentrations were 1.7-416,36.7-495 and 28.1-104 pg g(-1) dw 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 Sigma PCBs and higher than 1 for Sigma PEDEs. BAF values decreased with increasing soil concentrations, suggesting that high background levels in soil restricted the accumulation of these contaminants by plants. (C) 2015 Elsevier Ltd.
