海鸟位于海洋食物网的高位，积累了高浓度的持久性有机污染物，如多氯联苯（PCB）、二氯二苯三氯乙烷及其代谢物（DDTs）和六氯环己烷（HCH）。我们以前的研究提出了有用的海鸟羽毛腺油作为一种非破坏性的生物监测工具。本研究将这种方法应用于2005-2016年期间从11个地点收集的24种154只成年鸟类，以证明羽腺油作为全球监测持久性有机污染物的工具的实用性，即，多氯联苯、滴滴涕和六氯环己烷。北方半球的持久性有机污染物浓度高于南半球。特别是，∑ 20 PCBs和∑DDTs高度集中在欧洲沙鸡（Phalacrocorax aristotelis）和日本鸬鹚（Phalacrocorax capillatus）中，这可以解释为底栖鱼类的饮食。在来自极地地区的物种中检测到较高浓度的γ-六氯环己烷，这可能反映了最近接触和全球蒸馏∑六氯环己烷的情况。我们研究了年龄和持久性有机污染物浓度之间的关系，从20名男性欧洲沙格，年龄3-16岁。持久性有机污染物的浓度和组成与年龄无关。我们还研究了性别差异的POP浓度从24条纹剪（Calonectris leucomelas），并没有检测到性别偏见。这些结果强调的重要性，地理浓度模式和饮食行为的决定因素物种特定的持久性有机污染物的浓度在羽毛腺油。
Situated at high positions on marine food webs, seabirds accumulate high concentrations of persistent organic pollutants (POPs), such as polychlorinated biphenyls (PCBs), dichlorodiphenyltrichloroethane and its metabolites (DDTs), and hexachlorocyclohexanes (HCHs). Our previous studies proposed the usefulness of seabirds preen gland oil as a nondestructive biomonitoring tool. The present study applied this approach to 154 adult birds of 24 species collected from 11 locations during 2005–2016 to demonstrate the utility of preen gland oil as a tool for global monitoring POPs, i.e., PCBs, DDTs, and HCHs. Concentrations of the POPs were higher in the Northern Hemisphere than in the Southern Hemisphere. In particular, ∑20PCBs and∑DDTs were highly concentrated in European shags (Phalacrocorax aristotelis) and Japanese cormorants (Phalacrocorax capillatus), explainable by a diet of benthic fishes. Higher concentrations of γ-HCH were detected in species from the polar regions, possibly reflecting the recent exposure and global distillation of ∑HCHs. We examined the relationship between age and POP concentrations in preen gland oil from 20 male European shags, aged 3–16 years old. Concentrations and compositions of POPs were not related to age. We also examined sex differences in the POP concentrations from 24 streaked shearwaters (Calonectris leucomelas) and did not detect a sex bias. These results underline the importance of the geographic concentration patterns and the dietary behavior as determinants species-specific POPs concentrations in preen gland oil.
