摘　　要：本文应用六种稀土硝酸盐在Ａｍｅｓ法对ＴＡ９８及ＴＡ１００菌株到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，表现出抗诱变反应。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.
