摘 要：
为探讨载铜凹凸棒粘土对小鼠组织中Cu~(2+)含量的影响,选取32只ICR小鼠,随机分成3组,饲喂添加不同浓度载铜凹凸棒粘土的鼠粮,试验期20 d。通过ICP光谱仪检测小鼠粪便、血液、毛发以及脏器中Cu~(2+)的浓度。结果表明:各剂量组小鼠粪便中Cu~(2+)浓度随试验周期呈递增趋势,说明该粘土可能在胃肠道中滞留;各剂量组小鼠主要通过粪便的形式将20%~30%Cu~(2+)含量排出体外,并且在小鼠血液、毛发以及各脏器中几乎没有残留。

摘 要：
In order to understand the effect of Cu~(2+)-modified palygorskite on Cu~(2+)contents in the tissues of mice,we measured the concentrations of residual Cu~(2+)in feces,blood,hair and organs of 32 mice by ICP spectrometer. The results showed that in the experimental groups,the concentration of Cu~(2+)in feces tended to increase as the test went on,which suggested that there might be Cu~(2+)-modified palygorskite residues in the stomach and intestines. The mice in all the experimental groups excreted 20% ~ 30% of Cu~(2+)mainly through feces,and there were almost no Cu~(2+)residue in their blood,hair and other organs.
