Harbour porpoises sampled within the UK Cetacean Strandings Investigation Programme have been analysed for 25 chlorobiphenyl congeners. In all, 440 porpoises stranded or bycaught during the period 1991-2005 were studied. There are regional differences in the trend in summed congener concentrations over time but, despite controls on PCBs having been in place for decades, they are declining only slowly. Their toxic impacts in UK porpoises - increased susceptibility to infectious disease mortality in the most contaminated individuals - looks likely to continue for some time yet. Further efforts to limit or eliminate PCB discharges to the marine environment are still needed.
在英国鲸类搁浅调查计划中取样的港豚，被分析了 25 种氯联苯同系物。在 1991 年至 2005 年期间，共有 440 头搁浅或误捕的港豚被研究。尽管几十年来一直控制多氯联苯，但随着时间的推移，它们的浓度总和呈下降趋势，但仍存在区域差异。它们在英国港豚中的毒性影响——最受污染个体对传染病死亡率的易感性增加——可能还会持续一段时间。仍需要进一步努力限制或消除向海洋环境排放多氯联苯。
