宁东能源化工基地土壤中汞污染现状与分布特征

Status and Distribution of Mercury Pollution in Soil of Energy and Chemical Industry Base of Ningdong

分析了宁东能源化工基地土壤中总汞含量及空间分布状况。采用地累积指数法,评价了土壤中总汞的污染程度。结果表明:8个采样区域及72个采样点部分地区存在不同程度的汞污染,其中轻度污染和偏中度污染水平分别占45.83%和13.89%,未受污染点占40.28%。各个工业园区均有不同程度的污染,而园区中部污染最严重。

This paper analyzes the content and space distribution of total mercury in soil of Energy and Chemical Industry Base of Ningdong,using the geoaccumulation index method to evaluate the pollution degree of total mercury in the soil. The results show that there are different levels of mercury pollution at 8 sampling areas and 72 sampling points,the light pollution and moderate pollution level accounted for 45. 83% and 13.89% respectively,no pollution points accounted for 40. 28%. Every industrial park has different degrees of pollution,the central area of the park is the most serious pollution.
