Waterbirds are considered the effective sentinels of aquatic ecosystems contamination and their feathers are widely used as non-destructive biological tools for contaminant biomonitoring. In this work, we measure and evaluate the concentrations of lead, copper and zinc in the breast feathers of three species namely Fulica atra, Anas crecca and Anas platyrhynchos in the wetland National Park Boujagh. Levels of lead (Pb), copper (Cu) and zinc (Zn) were below the threshold that causes sub-lethal and reproductive effects. Significant differences in metal concentrations were found among bird species. The finding indicated that highest Pb and Zn concentrations were observed in common Coot. The effect of sex on heavy metal was observed for Pb in Anas platyrhynchos and while Cu, Zn in Anas crecca. Concentrations of metals were significantly (p < 0.05) higher in resident birds than in migratory. High levels of these heavy metals show that these birds can be used to monitor contamination in the wetland.

来自伊朗北部的三种水禽鸟类的羽毛，用于重金属生物监测。

水鸟被认为是水生生态系统污染的有效前哨，水鸟的羽毛被广泛用作污染物生物监测的非破坏性生物工具。在这项工作中，我们测量和评估了湿地国家公园Boujagh中三种物种（Fulica atra，Anas crecca和anas platyrhynchos）的胸羽中铅，铜和锌的浓度。铅（Pb），铜（Cu）和锌（Zn）的水平低于引起亚致死和生殖影响的阈值。在鸟类中发现金属浓度存在显着差异。该发现表明在普通老傻瓜中观察到最高的Pb和Zn浓度。性别对重金属中铅的影响。野鸭（Anas platyrhynchos）和铜，蛙中的铜，锌。 居住鸟类中的金属浓度显着高于迁徙鸟类（p <0.05）。这些重金属含量高表明这些鸟类可用于监测湿地中的污染。
