This study was conducted to measure the Cd, Pb, Cu, Zn, Cr, Co, Ni, and Fe concentrations in organs of Cyprinus carpio and Hypophthalmichthys molitrix, in Zabol Chahnimeh reservoirs, Iran. The highest Pb, Cu, Co, Ni, and Fe concentrations in both fish species were observed in the gill of C. carpio at 0.70, 3.7, 0.7, 0.8 and 31.2 µg/g, respectively; while the highest concentrations of Cd, Zn, and Cr were found in the gill of H. molitrix at 0.13, 22.5, and 0.5 µg/g, respectively. The maximum allowable fish consumption rate for an adult person (71.5 kg body weight) were 10.64, 0.677, 0.558, 1.17, and 0.92 kg/day based on Cd, Cu, Cr, Zn, and Fe levels respectively. Results showed that the Cd, Cu, Zn, and Pb (except of Pb in H. molitrix) concentrations in the muscle of both fish species are below levels of concern for human consumption.
本研究旨在测量伊朗扎博勒恰赫梅赫水库中鲤鱼和鲫鱼各器官中的 Cd、Pb、Cu、Zn、Cr、Co、Ni 和 Fe 浓度。在这两种鱼类中，Pb、Cu、Co、Ni 和 Fe 的浓度在鲤鱼的鳃中最高，分别为 0.70、3.7、0.7、0.8 和 31.2μg/g；而 Cd、Zn 和 Cr 的浓度在鲫鱼的鳃中最高，分别为 0.13、22.5 和 0.5μg/g。基于 Cd、Cu、Cr、Zn 和 Fe 的水平，一个 71.5 公斤体重的成年人的最大允许鱼类食用量分别为 10.64、0.677、0.558、1.17 和 0.92 公斤/天。结果表明，两种鱼类肌肉中的 Cd、Cu、Zn 和 Pb（除了鲫鱼中的 Pb）的浓度均低于人类食用的关注水平。
