摘要
为了探讨矿区长期的生产活动对镇区土壤环境质量的影响,以水口山镇土壤为研究对象,采集了69个表层土壤的混合样品,评价了土壤中重金属Pb、Cd、Zn、Hg、Cu、As的污染程度并探讨其空间分布规律。结果表明:单因子污染指数评价除Hg为轻度污染外其余均为重度污染,单因子污染指数排序为Cd>Pb>Zn>Cu>As>Hg,As、Cu和Pb三种重金属高含量区主要集中在水口山金属有限公司以及裸露的矿区,Cd和Zn重金属高含量区主要集中在工厂冶炼区内。内梅罗综合污染指数评价水口山镇土壤已受到重金属的严重污染,未受到污染的地区少,综合污染指数排序为北部工厂冶炼区>南部裸露矿区>其他区域。研究结果可为水口山镇的土壤重金属整治提供理论基础。
In order to explore the effects of long-term production activities on the environmental quality of soil in the township, the soil of Shuikoushan Town was taken as the research object, and 69 mixed soil samples were collected to evaluate the pollution degree of heavy metals Pb, Cd, Zn, Hg, Cu and As in the soil and to discuss the spatial distribution rule. The results show that the pollution amount of Hg is low and the pollution amount of other metals is very high. The index in descending order is Cd, Pb, Zn, Cu, As, Hg. The areas with high content of As, Cu and Pb are mainly concentrated in Shuikoushan Metal Limited Company and the exposed mining areas, while the areas with high content of Cd and Zn are mainly concentrated in the smelting areas of factories. Nemero comprehensive pollution index analysis shows that the soil of Shuikoushan town has been seriously polluted by heavy metals, among which there are few areas that are not polluted. The comprehensive pollution index from large to small is the smelting area in the north, the exposed mining area in the south, and other areas. The results can provide a theoretical basis for soil heavy metal management of soil in Shuikoushan town.
