Polychlorinated biphenyls (PCBs), total DDT (DDT + DDE + DDD), dieldrin, heptachlor epoxide, chlordanes, and hexachlorobenzene (HCB) were found in blubber biopsies from endangered North Atlantic right whales (Eubalaena glacialis) in the Bay of Fundy and on Browns-Baccaro Banks. Analyses included four sex and age class composite samples from 1988, and 21 individual samples from 1989. Generally, PCBs demonstrated the highest wet weight residue levels (up to 1.9 micrograms/g), followed by total DDT (DDT + DDE + DDD) (trace to 0.47 micrograms/g). Relatively low residue levels in adult females suggest that transmammary organochlorine (OC) residue transfer occurs during lactation. The actual blubber residue loads may have been underestimated, because the samples were taken when the whales were depositing fat reserves and the samples may not have been representative of the remainder of the blubber.
在芬迪湾和布朗斯 - 巴卡罗浅滩的濒危北大西洋露脊鲸（Eubalaena glacialis）的鲸脂活检样本中，发现了多氯联苯（PCBs）、总滴滴涕（滴滴涕+滴滴伊+滴滴滴）、狄氏剂、环氧七氯、氯丹和六氯苯（HCB）。分析包括1988年的4个性别和年龄组混合样本，以及1989年的21个个体样本。一般来说，多氯联苯的湿重残留水平最高（高达1.9微克/克），其次是总滴滴涕（滴滴涕+滴滴伊+滴滴滴）（痕量至0.47微克/克）。成年雌性体内相对较低的残留水平表明，哺乳期会发生经乳腺的有机氯（OC）残留转移。实际的鲸脂残留量可能被低估了，因为样本是在鲸鱼储存脂肪储备时采集的，这些样本可能不代表其余的鲸脂情况。
