A selection of PCN congeners was analyzed in pooled blubber samples of pilot whale (Globicephala melas), ringed seal (Phoca hispida), minke whale (Balaenoptera acutorostrata), fin whale (Balaenoptera physalus), harbour porpoise (Phocoena phocoena), hooded seal (Cystophora cristata) and Atlantic white-sided dolphin (Lagenorhynchus acutus), covering a time period of more than 20 years (1986-2009). A large geographical area of the North Atlantic and Arctic areas was covered. PCN congeners 48, 52, 53, 66 and 69 were found in the blubber samples between 0.03 and 5.9 ng/g lw. Also PCBs were analyzed in minke whales and fin whales from Iceland and the total PCN content accounted for 0.2% or less of the total non-planar PCB content. No statistically significant trend in contaminant levels could be established for the studied areas. However, in all species except minke whales caught off Norway the lowest ∑PCN concentrations were found in samples from the latest sampling period.
选择了一些 PCN 同系物，对领航鲸（Globicephala melas）、环斑海豹（Phoca hispida）、小须鲸（Balaenoptera acutorostrata）、长须鲸（Balaenoptera physalus）、港湾鼠海豚（Phocoena phocoena）、冠海豹（Cystophora cristata）和大西洋白海豚（Lagenorhynchus acutus）的混合鲸脂样本进行了分析，这些样本涵盖了超过 20 年的时间（1986-2009 年）。涵盖了北大西洋和北极地区的大片地区。在 0.03 到 5.9ng/g lw 之间的鲸脂样本中发现了 PCN 同系物 48、52、53、66 和 69。此外，还在冰岛的小须鲸和长须鲸中分析了多氯联苯，PCN 的总含量占总非平面多氯联苯含量的 0.2%或以下。在所研究的区域中，没有建立污染物水平的统计显著趋势。然而，除了在挪威沿海捕获的小须鲸外，在所有其他物种的样本中，最新采样期的∑PCN 浓度最低。
