季节性的摄食行为和对摄食区域的高保真度使得座头鲸（Megaptera novaeangliae）可以作为区域污染的生物指标。来自雄性个体（n=67）的活检鲸脂样本是通过多国研究项目SPLASH在北太平洋的8个摄食地收集的。另外从北大西洋的一个取食地采集雄性样本（n=20）。对样品中的持久性有机污染物进行了测量，并用于评估研究区域的污染物分布。北大西洋（缅因湾）的鲸鱼比北太平洋的鲸鱼受到的污染更严重，多氯联苯（PCBs）、多溴联苯醚（PBDEs）和氯丹的含量最高。在以南加州为食的鲸鱼身上检测到的DDT含量最高。美国。高纬度地区的特点是六氯环己烷（HCHs）水平升高，但多溴二苯醚的浓度通常检测不到。年龄与西格玛多氯联苯、西格玛DDTs、西格玛氯丹和总脂质百分比呈正相关。座头鲸体内的污染物水平与其他神秘动物相当，低于齿形动物、鲸类和鳍足动物体内的污染物水平。虽然这些浓度可能不会对环境保护构成重大威胁，但缅因湾和南加州的水平可能值得进一步研究。环绕。Toxicol。化学2010;29:824 - 834。(c) 2009年setac
Seasonal feeding behavior and high fidelity to feeding areas allow humpback whales (Megaptera novaeangliae) to be used as biological indicators of regional contamination. Biopsy blubber samples from male individuals (n=67) were collected through SPLASH, a multinational research project, in eight North Pacific feeding grounds. Additional male samples (n=20) were collected from one North Atlantic feeding ground. Persistent organic pollutants were measured in the samples and used to assess contaminant distribution in the study areas. North Atlantic (Gulf of Maine) whales were more contaminated than North Pacific whales, showing the highest levels of polychlorinated biphenyls (PCBs), polybrominated diphenyl ethers (PBDEs), and chlordanes. The highest dichlorodiphenyltrichloroethane (DDT) levels were detected in whales feeding off southern California. USA. High-latitude regions were characterized by elevated levels of hexachlorocyclohexanes (HCHs) but generally nondetectable concentrations of PBDEs. Age was shown to have a positive relationship with Sigma PCBs, Sigma DDTs, Sigma chlordanes, and total percent lipid. Contaminant levels in humpback whales were comparable to other mysticetes and lower than those found in odontocete cetaceans and pinnipeds. Although these concentrations likely do not represent a significant conservation threat, levels in the Gulf of Maine and southern California may warrant further study. Environ. Toxicol.
