摘  要：
通过测定新疆若羌县表层土壤中8项重(类)金属元素[铬、汞、镍、铅、砷(类金属)、铜、锌、镉]的含量,采用单因子指数法评价研究区土壤重(类)金属环境质量状况,并应用Hankanson潜在生态风险指数法对土壤潜在生态风险进行评价。结果表明,若羌县土壤重(类)金属环境质量较好,8项指标中铬、汞、铅、铜、锌、镉等6项均低于国家标准限值,土壤综合污染级别属于安全级别;农业区土壤主要污染物为镍,其超标率为0.7%;非农业区土壤主要污染物为砷和镍,其超标率分别为0.7%和0.3%。若羌县土壤整体上存在轻微生态风险。

摘  要：
Based on the contents of Cr,Hg,Ni,Pb,As(metalloid),Cu,Zn and Cd in surface soil in Ruoqiang County of Xinjiang,soil heavy metal(metalloid)environmental quality and ecological risks of heavy metals(metalloid)in soil of the study area were evaluated by single factor index method and Hankanson potential ecological risk index method.The results showed that soil heavy metal(metalloid)environmental quality in Ruoqiang County was better.The contents of Cr,Hg,Pd,Cu,Zn and Cd were under the level of national standard,and synthetic soil pollution level was in the range of safety.The main pollutant in soil of agricultural region was Ni,and the over standard rate was 0.7%;the main pollutants in soil of non-agricultural region were As and Ni,and the over standard rate was 0.7% and 0.3%respectively.In addition,the potential ecological risk in soil analysis suggested that there was a slight risk to local ecosystem originated from heavy metal(metalloid)contamination in soil in Ruoqiang County.
