| 摘 要： | 为了了解运城盐湖区农田土壤中重金属元素含量状况及对土壤质量的影响,对土壤中5种重金属元素的监测结果进行了比较分析,结果表明:全部土壤汞、砷、铬含量均符合土壤环境质量Ⅰ级标准,没有汞、砷、铬污染。部分农田土壤中铅只符合土壤环境质量Ⅱ级标准,已有轻度铅污染的趋势。大部分土属中镉只符合土壤环境质量Ⅱ级标准,镉有大面积轻度污染的趋势。以后应加强对农田土壤重金属元素污染的预防与监管。

| Abstract: | In order to know the heavy metals in soils in salt lake district and the influence on the soil quality of Yuncheng,five heavy metal elements in soil were monitored and analyzed.The results showed that the content of mercury,arsenic and chrome in all siol conformed to the level 1 of standards of soil environment quality in China which proved there was no mercury,arsenic,and chrome pollution.However the content of lead in some soil only conformed to the level 2 of standards of soil environment quality in China,suggesting the soils had tended to be slightly polluted by lead.The content of cadmium in most soils conformed to the level 2 of standards,demoustrating the soils tended to be popluted slightly by cadmium over an extensive area.Consequently the prevention and montoring of heavy metal elements pollution in siols should be strengthened. |
