The aim of this study was to explore the usefulness of feathers as a biomonitoring tool for organochlorine pesticides (OC) in a razorbill population (Alca torda). Fifteen OC were analyzed in feathers, including α-, β- and δ-hexachlorocyclohexane, lindane, aldrin, dieldrin, endrin, endosulfan I and II, endosulfan sulfate, p,p'-DDT, DDD, DDE, heptachlor and its epoxide. The geometric mean concentrations observed in this study were ∑DDT 67.40 ng/g, ∑HCH 62.88 ng/g, ∑Heptachlor 61.75 ng/g, ∑Endosulfan 19.70 ng/g, and ∑Drins 10.17 ng/g. The higher OC levels found in this study compared with other studies are probably affected by the razorbill diet and migration status. However, levels found in the feathers of the present study are related to concentrations in internal tissues below those which cause adverse reproductive and behavioral effects or other signs of organochlorine-pesticide poisoning in birds. Age does affect the concentration of OC pesticides in feathers. Thus, feathers would appear to be a promising tool for OC biomonitoring in seabirds, since it is possible to quantify OC compounds.
本研究旨在探讨羽毛作为海雀种群有机氯农药（OC）生物监测工具的有用性。在羽毛中分析了 15 种 OC，包括 α-、β-和 δ-六氯环己烷、林丹、艾氏剂、狄氏剂、异狄氏剂、硫丹 I 和 II、硫丹硫酸盐、p,p'-DDT、DDD、DDE、七氯及其环氧化物。本研究中观察到的几何平均值浓度为∑DDT 67.40ng/g、∑HCH 62.88ng/g、∑Heptachlor 61.75ng/g、∑Endosulfan 19.70ng/g 和∑Drins 10.17ng/g。与其他研究相比，本研究中发现的更高 OC 水平可能受海雀饮食和迁徙状况的影响。然而，本研究中羽毛中的浓度与引起不良生殖和行为影响或鸟类有机氯农药中毒其他迹象的内部组织浓度有关。年龄确实会影响羽毛中 OC 农药的浓度。因此，羽毛似乎是海鸟 OC 生物监测的一种很有前途的工具，因为可以定量 OC 化合物。
