Polychlorinated biphenyls (PCBs) and polybrominated biphenyl ethers (PBDEs) in environmental samples from Ny-Alesund and London Island, Svalbard, the Arctic
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...
