摘要/Abstract

摘要： 分析了太湖鼋头渚夜鹭幼鸟各组织样品中Cd、Pb、Cr、Hg、Se等重金属的残留水平,发现Cr与Se在各组织中的残留量相对较高,而Cd的残留量最低.从几种重金属在各组织中的分布特征来看,Pb和Cd在羽毛中残留水平最高,Se、Hg、Cr在肝脏中残留量最高.研究证实羽毛和肝脏是重金属富集的主要目标器官,而且Hg和Cd等重金属残留水平与Se含量有一定的相关性.同其它类似研究结果相比,该地区夜鹭体内的重金属污染水平尚未达到明显的致害浓度.

Abstract: This study analyzed Cd, Pb,Cr,Hg and Se in organs and tissues of night heron chick bred in Yuantouzhu,Taihu lake.Cr and Se have higher residue level in all the samples,compared to the residue of Cd.Pb and Cd mainly concentrated in feathers,on the other hand,Se,Hg and Cr were accumulated in livers.The results proofed that feather and liver were the object organs for accumulation of heavy metals.The data showed that Hg and Cd have some relationship with Se in birds.Compared with other studies,residue levels of heavy metals in night heron in Wuxi were not harmful.

Key words: Night heron, Heavy metals, Feather, Brain, Liver, Muscle
