摘要：

We report concentrations of organochlorine pesticides (HCB, HCHs, DDTs, dieldrin) and PCBs in the blubber of 43 common dolphins bycaught in fisheries operating off the SW coast of the UK from 1992 to 2006. Concentrations of Sigma DDT (summed p,p'-DDT and its metabolites, p,p'-DDE and p,p'-TDE) and of 25 summed CB congeners ranged from 0.2 to 16.1 and 2.1 to 62.4 mg kg(-1) lipid weight, respectively. Concentrations of sum HCH, HCB and dieldrin were lower, ranging from not detected to 0.14, 0.01 to 0.27 and 0.01 to 0.73 mg kg(-1) lipid weight, respectively. All contaminants studied showed a downward time trend but only that for HCHs was statistically significant. Overall, 72% of the dolphins analysed had blubber PCB concentrations above an established toxicity threshold value. Crown Copyright (c) 2012 Published by Elsevier Ltd. All rights reserved.
