摘 要: 通过在饮水中加入稀土钇 (0 ,2 3.2 5 m g/ L ,2 32 5 .0 0 mg/ L )使小白鼠长期摄入稀土 ,7个月后用 ICP-MS以及原子荧光法测定 F1子代小鼠全血中微量元素 Ca、Mg、Cu、Zn、Fe、Se等的含量 ,并计算其比值。结果显示 ,F1子代小鼠全血中 Se含量与对照相比显著增加 (低浓度组 P<0 .0 1,高浓度组 P<0 .0 5 ) ;高浓度组小鼠全血中Ca/ Fe、Ca/ Fe比值发生显著变化 (P<0 .0 1)。提示稀土钇的长期摄入可影响小鼠体内某些微量元素之间的平衡 ,这种平衡的变化可能引致机体某些生理状态的变化。 The mice were fed with water dissolved different level Y 3+ (0, 23 25mg/L, 2325 00 mg/L)for seven months,the level of trace elements such as Cu, Zn, Mn, Fe, Mg, Ni, Co in whole blood of F1 generation mice were then determined by ICP-MS and atom fluorospectrophotometer. The results show that, compared with control, significant changes in level of Se (P<0 01) and in ratio of Ca/Zn, Ca/Fe were observed These results suggest that Y 3+ may have an effect on the balance between some trace elements in tissue, which may be a cause of the biological effect of rare earth
