摘要
对铅、镉、汞以及镧、铈在鲤鱼体内的生物富集作用进行了室内试验和讨论。结果表明,重金属及稀土元素在鱼体各部位均有较强的富集作用,其中肌肉部分富集能力较弱,内脏富集能力最强;鱼体各部位对重金属及稀土元素的富集作用随时间的增加而增加,在一定的时间后趋于平衡;并且,鱼体中各部位对重金属及稀土元素的生物富集作用存在较大差异。
The biological accumulation of Pb, Cd, Hg, La,Ce in carp bodies has been studied and discussed. The conclusion is that the elements can be accumulated by carps. The accumulation differs greatly from different organs of carp,the muscle system is the least, and the internal organs is the highest. The accumulation is increasing and reaches an equilibrum after a certain period of time.
