摘要
对海南岛西部农业用地表层土壤进行了7种重金属元素含量测定,重金属元素的富集指数计算和相关性分析。结果表明:海南岛西部农业用地表层土壤中重金属元素富集程度大小依次为As>Pb>Zn>Cu>Ni>Cd>Cr。各采样点Cr、Cd和Cu元素处于贫乏状态,As和Pb元素达到严重富集,可能与当地农业活动密切相关。相关性分析表明,研究区土壤表层中重金属As与Pb元素可能存在复合富集与复合污染,应引起高度重视。
This research has 7 kinds of heavy metal elements in surface soil from agricultural land of west Hainan island monitored and measured. The heavy metal elements enrichment index calculation and correlation analysis indicate that the pollution degrees of 7 kinds of heavy metal elements were different. Its order was： As〉Pb〉Zn〉Cu〉Ni〉Cd〉Cr. Cr, Cd and Cu were in poor condition, and As and Pb were serious enriched in each sample point, reflecting that soil pollution was influenced by local human agricultural activities. The result shows that more attention should be paid to the As and Pb of heavy metal elements because of their enrichment and pollution.
