The concentrations of Cu, Mn, Cd, Fe, Ni and Zn of the scales, bladder, heart, muscle, gill cover bone, tail fin, brain, kidney, skin, gall bladder, eyes, intestine, gill and hepatopancreas of the bighead carp Aristichthys nobilis from the Huaihe River near Bengbu spectrophotometry. The results showed that the content City were determined by flame type atomic absorption of heavy metals mentioned above was different in the tis- sues and organs, in which Fe （59. 168mg/kg） and Zn （50. 220mg/kg） were significantly higher than other heavy metals. The content of Fe （370.220 mg/kg） and Zn （229. 659 mg/kg） was the highest in Bighead carp heart, followed by intestine, gill, liver, spleen. Cu~ content was higher （ 13. 254mg/kg, 8. 874 mg/kg, 3. 120 mg/kg） than other tissues in the liver and pancreas, heart and intestine. Mn＇s content was higher in the gut, and gill cover bones, and gills, while it was the lowest in the heart; Cd and Ni~ content were higher in heart, bladder, scales, but it was lower in the intestine. But Cd~ content of different tissues in the Huaihe River Big- head carp were higher than the National health standards for health food. its edible harts can not be eaten.%应用火焰型原子吸收光度法测定淮河鳙鱼（Aristichthysnobilis）不同组织器官（鳞片、鳔、心脏、肌肉、鳃盖骨、尾鳍、脑、脾、皮肤、胆、眼球、肠、鳃和肝胰脏）中的Cu、Mn、Cd、Fe、Ni和zn等6种重金属含量。结果表明，淮河鳙鱼不同组织器官中的Cu、Mn、Cd、Fe、Ni和Zn的含量不同，其中Fe（59．168ms／ks）和zn（50．220mg／kg）含量均明显高于其他重金属含量，鳙鱼心脏中Fe（370．220mg／kg）和Zn（229．659mg,／kg）含量最高，其次为肠、鳃、肝胰脏；Cu在肝胰脏、心脏和肠中的含量较高（13．254mg／kg、8．874mg／kg、3．120mg／kg），其他组织较低；Mn在肠、鳃盖骨、鳃中含量较高，但心脏中含量最少；Cd和Ni在心脏、鳔、鳞片、鳃盖骨中含量较高，在肠中的含量均较低，但淮河鳙鱼不同组织中Cd的含量超过国家卫生食用标准，茸食用都会不能食用．
