| 摘 要： | 比较不同时期提出的稀土元素日允许摄入量(AD I)的差异性发现,随着研究的深入,近期提出的AD I值明显低于早期的AD I值,反映了人们对稀土元素毒性效应有了进一步的认识。根据农产品中稀土元素残留量及其可通过食物链为人们所摄入的现状,分析了稀土农用、稀土厂“三废”对生态环境的污染影响以及潜在的食品安全性问题。

| Abstract: | Comparison of ADIs(acceptable daily intake) of rare earths elements proposed at different times reveals that the ADIs proposed recently are much lower than those in the past,reflecting that rare earth elements do have biotoxic effects.Based on the findings that agricultural products containing higher rare earth elements residues may enter human body through food chain,potential environment risks of their agricultural application and wastes from rare earth refineries are discussed and potential food safety issues are analyzed. |

| Keywords: | rare earth element(RE) acceptable daily intake(ADI) residue food safety |
