Seabirds are used as bioindicators of marine ecosystems, especially for quantifying and tracking pollution sources. The objective of this study was to evaluate the contamination in feathers of young kelp gulls by lead (Pb), chromium (Cr), mercury (Hg) and zinc (Zn) on three islands of southern Brazil. The highest values for Pb (2.1310 μg g) and Hg (0.0010 μg g) were observed in Lobos. Zn was common in all samples with a median around 41.7487 μg g and Cr values were below the quantification limit (0.0300 μg g). The Kruskal-Wallis test indicated significant differences in Pb (H = 21.84; p < 0.05) and Zn (H = 958.80; p < 0.05), but no differences were observed in Cr (H = 3.08; p < 0.05) and Hg (H = 3.0; p < 0.05). This study was important to show the impact of trace element pollutants on the seabird communities and oceans.
海鸟被用作海洋生态系统的生物指标，特别是用于量化和跟踪污染源。本研究的目的是评估巴西南部三个岛屿上幼年巨藻鸥羽毛中铅（Pb）、铬（Cr）、汞（Hg）和锌（Zn）的污染情况。在洛博斯观察到 Pb（2.1310μg g）和 Hg（0.0010μg g）的最高值。Zn 在所有样本中都很常见，中位数约为 41.7487μg g，Cr 值低于定量限（0.0300μg g）。Kruskal-Wallis 检验表明 Pb（H=21.84;p<0.05）和 Zn（H=958.80;p<0.05）存在显著差异，但 Cr（H=3.08;p<0.05）和 Hg（H=3.0;p<0.05）没有差异。本研究对于展示微量元素污染物对海鸟群落和海洋的影响很重要。
