【摘要】 对黑河市上马厂村不同土地利用背景下3个功能区的6种重金属元素(Hg、As、Cd、Cr、Cu、Pb)进行了研究,同时考察了重金属含量与采样深度的关系,并对重金属污染状况进行了总体评价。结果表明:重金属Hg的污染最为严重,已达到了警戒水平;而其他重金属则处于安全水平。总体来说黑河市上马厂村所研究区域土壤处于清洁水平,满足绿色食品和蔬菜生产的要求。更多还原

【Abstract】 The content of Hg、As、Cd、Cr、Cu and Pb in different functional zones is studied,the relationship between heavy metals and sampling depth is analyzed. The results show the content of Hg is high and should be paid more attention. And other metals are safe for agricultural production. The soil is at clean level on the whole,so the soil meets the needs of producing green food and vegetables.更多还原
