Recent studies on the competition between Cd and radionuclides have been reported in marine species. The present investigation aims to study the binding of 241Am to freshwater fish cytosolic fraction before and after Cd-treatment. The main organs studied are the liver, kidneys and muscles. The distribution of americium in the liver cytosol of carp cadmium treated shows a preferential fixation on a 10 KDa fraction with high sulfhydril compounds.
近期已有关于海洋物种中镉与放射性核素之间竞争关系的研究报道。本研究旨在探究经镉处理前后，淡水鱼胞质组分与241Am的结合情况。所研究的主要器官为肝脏、肾脏和肌肉。经镉处理的鲤鱼肝脏胞质溶胶中镅的分布情况表明，其优先固定在含有高含量巯基化合物的10千道尔顿组分上。
