| 摘 要： | 本文应用六种稀土硝酸盐在Ａｍｅｓ法对ＴＡ９８有ＴＡ１００菌测试中的回变菌落数与阴性对照的自发回变菌落数基本一致，显示无致突变作用；而硝酸铈在每皿５０μｇ－５０００μｇ时，能减少２ＡＦ的致突变菌落数，表现出抗旅为反应。

STUDY ON MUTAGENIC EFFECT OF RARE EARTH NITRATES |

| Abstract: | The mutagenic cffects of six rare carth nitratcs was investigated with Ames Test.The results showed that the revertants indueed by the six rare carth nitrates were equivalentto that of the spontaneaus mutation in control.The rcsult from anti-mutation test indicatedCe(NO3)3 could reduce the revertants indueed by 2AF it suggcsts its potential anti-muta-genic cffect. |
