摘要: 综合论述了稀土元素在机体内的蓄积性及其毒性效应,分析了稀土农业应用对生态环境和人群骨系统健康的潜在危害。稀土元素被长期低剂量摄入,可在骨组织中蓄积,导致骨组织结构变化,骨髓微核率增高,产生遗传毒性。

Abstract: A comprehensive review is presented of accumulation and toxicity of rare earth elements in human body,with stress on potential hazard of rare earth element fertilizers used in agricultural production to the environment and health of the human skeletal system.Long-term intake of low dose rare earth elements may lead to accumulation in the bone structure,leading to changes in the bone tissue and increased bone marrow micronucleus rate and further to generation of genetic toxicity in bone marrow cells.

Key words: rare earth element, bio-effect, bone, bone marrow, accumulation, toxicity
