We investigated the concentrations of cadmium, chromium, copper, iron, nickel, lead and zinc among feather tissues in sexes of Black-browed Albatross Thalassarche melanophrys killed in longliners off Argentina in 2005. We found no different metal concentration with sex for cadmium, copper, iron, lead and zinc in feathers of adult birds, though there were significant body-size differences between sexes. However, the concentrations of trace metals differed significantly among the type of feather within individual bird. The mean concentrations of copper, iron, and zinc in breast feathers of T. melanophrys were lower than those reported for the species from Georgias del Sur/South Georgia, the southern Indian Ocean and for other seabirds' worldwide. While cadmium fall within the known range of concentrations for bird feathers lead were not. Our results may be indicating that level of pollution in Patagonia may not be as negligible as previously thought at least for some trace metals.
我们研究了 2005 年在阿根廷延绳钓渔船上捕获的黑眉信天翁（Thalassarche melanophrys）雌雄成鸟羽毛组织中镉、铬、铜、铁、镍、铅和锌的浓度。我们发现，尽管雌雄成鸟的体型大小存在显著差异，但在羽毛中，镉、铜、铁、铅和锌的浓度与性别无关。然而，同种鸟类的不同羽毛类型之间的微量元素浓度存在显著差异。黑眉信天翁的胸羽中铜、铁和锌的平均浓度低于南乔治亚岛/南桑威奇群岛、南印度洋和其他海鸟的报告值。而铅的浓度则不在已知的鸟类羽毛浓度范围内。我们的结果可能表明，巴塔哥尼亚地区的污染水平至少在某些微量元素方面可能不像之前认为的那样微不足道。
