摘要
稀土元素是镧系金属元素的总称，在地壳中含量稀少，约占１５×１０－６．我国对稀土元素的开发利用较早，特别是农业上稀土多元复合肥常与农药一起使用，这对生物和环境的影响为人们所关注，给环境研究带来了新课题．目前对稀土元素的研究主要集中在地球化学、农业化学和...
This paper presents the study on the effects of Er 3+ and rare earth multi element compound fertilizer(REMECF) on the formation of micronucleus(FMN)in root tip cells of Vicia faba .The study showed that the micronucleus could be induced by Er 3+ and REMECF,and suggested that Er 3+ and REMECF had genetic toxicity in root tip cells of Vicia faba .
