| Abstract: | The contents of heavy metals in Huaiyam and its planting area soil in Wen County were analyzed and the heavy metal pollution status was evaluated.The results indicated that the contents of heavy metals in yam soil were below the level 2 in the index 2 of the soil environment quality standard.Except that the content of Zn in Liuguozuo yam was slightly above,the other heavy metals in yam were below the national food limited standard.The beneficial element contents of Zn,Cu and Mn were higher,while the content... |
