混合重金属的相互作用对Cu在彭泽鲫组织中积累的影响

Effects of the Interaction of Three Kinds of Heavy Metals on the Accumulation of Copper in the Tissues of Carassius auratus Pengzenensis

研究了三种重金属离子(Cu、Zn、Cd)相互作用对Cu在彭泽鲫(Carassius auratusPengzenensis)组织中积累的影响,结果表明:混合重金属离子相互作用对Cu在彭泽鲫组织中积累的影响与离子的种类、数量及组织的类型有关,Cd离子影响显著,Zn离子影响不明显,随着重金属离子种类的增加,相互作用对其积累的影响变得更为显著,Cu离子在鱼脑、肾脏和鱼鳃中的积累浓度升高。三种重金属离子相互作用不会改变Cu在彭泽鲫组织中的分布规律,Cu在彭泽鲫组织中的积累顺序为肾脏、鱼脑、鱼鳃、肌肉。

This paper showed that accumulation of copper was related to metallic species and con -centration,and as well as fish tissues. The Interaction became more significant with the increase of the metals; the accumulation of the copper increased in kidney,brain and gill in the mixture -metal interaction, The other metals could not change the accumulation order of the copper in the tissues,the accumulation order of the Cu in the fish tissues was kidney 〉 brain 〉 gill 〉 muscle.
