Abstract

The risk of increased exposure to metals for a vertebrate predator foraging on aquatic insects in acidified lakes was investigated through analyses of the content of Al, As, Ca, Cd, Cu, Fe, Hg, Mn, Pb, Ru, Se, and Zn in the liver tissue of 42 non-fledged Goldeneye, Bucephala clangula, ducklings from acidic, circumneutral, and limed lakes in South Sweden. No indications of significantly different concentrations in samples from acidic lakes in comparison with circumneutral lakes were detected for any metal, but among individual birds from acidic lakes there were high contents of Hg. Liming probably affects the exposure to some metals; lower contents of Hg were recorded from limed lakes in comparison with acidic lakes, while the reverse trend was recorded for Cd and Mn.

摘要

通过分析瑞典南部酸性、中性和施石灰湖泊中42只未离巢的鹊鸭（Bucephala clangula）雏鸭肝脏组织中铝、砷、钙、镉、铜、铁、汞、锰、铅、钌、硒和锌的含量，研究了在酸化湖泊中捕食水生昆虫的脊椎动物捕食者接触金属增加的风险。与中性湖泊相比，在酸性湖泊样本中未检测到任何金属浓度有显著差异的迹象，但在来自酸性湖泊的个体鸟类中汞含量较高。施石灰可能会影响对某些金属的接触；与酸性湖泊相比，施石灰湖泊中汞的含量较低，而镉和锰则呈现相反的趋势。
