摘　　要：稀土元素广泛存在于自然界,存在于生物链之中。自从GB 2762-2005《食品中污染物限量》实施后,规定茶叶中稀土限量为小于等于2mg.kg^(-1)后,茶叶中稀土含量就受到广泛的关注。文章从土壤、肥料、茶叶中稀土及其检测方法等方面,简述其研究概况,并建议对现行茶叶中过于严格的稀土限量加以修订。The rare-earth element widely exists in the nature, exists in the biological chain. Since GB 2762- 2005 ＂Maximum lexels of contaminants in foods＂, the content of rare earth in teas limited after less and equal 2mg.kg^-1, then the content of rare earth in the tea receives the widespread attention. This article from the rare earth of soils, fertilizers, teas as well as its examination method and so on, summarizes its research progress. In the present, the author thought that the limited content of rare earth in teas strict should be revised.
