摘　　要：目的探讨不同浓度Cu2+对鲫鱼血红蛋白、体重以及肾、胰腺、肌肉和鳃内Zn2+含量的影响。方法暴露鲫鱼于含不同浓度Cu2+、Zn2+处理液中5 d,用原子吸收法测定金属Zn2+在鲫鱼鳃、肾脏、胰脏、肌肉组织中的含量;用鱼类致突变实验方法测定不同浓度Cu2+、Zn2+溶液中鲫鱼血蛋白含量。结果Cu2+能减少鲫鱼体内Zn2+和血红蛋白的量,同时引起鲫鱼体重下降增多,0.1和1 mg/L铜离子使鲫鱼肾脏和胰腺内的Zn2+和血红蛋白含量显著下降,方差分析差异有统计学意义(P<0.05)。结论较高浓度的Cu2+对鲫鱼体内Zn2+、血红蛋白含量和体重影响较大;Cu2+对鲫鱼的肾脏和胰腺影响较大,而对鳃和肌肉的影响较小。Objective To study influence of different concentration of Cu^2＋ on hemoglobin（Hb）, weight and Zn^2＋ content in kidney, pancreas, musculature and branchia of carassius auratus. Methods The content of Zn^2＋ in kidney, pancreas, musculature and branchia of carassius auratus was measured by atomic spectro photometry when the fish was put into the water with different concentration of Cu^2＋ and Zn^2＋ for 5 days. The test of fish mutagenesis was used to measure the Hb. Results The content of Zn^2＋ and Hb of carassius auratu was reduced by Cu^2＋ . When the Cu^2＋ concentration were 0.1 mg/L and 1 mg/L, the level of Zn^2＋ in kidney and pancreas and Hb in peripheral blood was greatly reduced by Cu^2＋ （P 〈 0.05）. Conclusion The higher Cu^2＋ concentration strongerly reduce the level of Zn^2＋ and Hb. The kidney and the pancreas are more easily affected by Cu^2＋ than those of the usculature and the branchia.
