The objective of the present study was to investigate the levels of metals (Cd, Cu, Zn, Pb and Cr) in muscle, gill, liver, kidney and intestine of two freshwater fish, Ctenopharyngodon idella and Perca fluviatilis, in Anzali Wetland, Iran. The concentrations were different between the fish species as well as among the tissues of fish. Results showed that the metal concentrations in both fish species were in descending order of Zn > Cu > Pb > Cr > Cd. Results also showed that the Cd, Cu, Zn, and Pb concentrations in the muscle of both fish from Anzali Wetland are below levels of concern for human consumption.
本研究旨在调查伊朗安扎利湿地两种淡水鱼类（草鱼和鱤鱼）肌肉、鳃、肝、肾和肠中金属（Cd、Cu、Zn、Pb 和 Cr）的含量。鱼类种间以及同种鱼类不同组织间的浓度存在差异。结果表明，两种鱼类的金属浓度均按 Zn > Cu > Pb > Cr > Cd 的顺序递减。结果还表明，安扎利湿地两种鱼类肌肉中的 Cd、Cu、Zn 和 Pb 浓度均低于人类食用关注水平。
