摘要
为探究含Hg废弃物处置、氯化汞及CB型低汞触媒的生产活动对厂区周边土壤Hg含量的影响,以贵州某典型企业周边土壤汞为研究对象,采用地累积指数法、潜在生态风险指数法对土壤Hg污染进行评价。结果表明:土壤Hg含量的平均值为1.58mg/kg,超过了贵州省土壤背景值;地累积指数平均值为3.07,达到了偏重污染水平;潜在生态风险系数平均值为572.73,达到了极强生态风险水平。建议采取有效措施以防止对周边土壤Hg污染影响。
In order to investigate the impact of Hg waste disposal,mercury chloride and CB low mercury catalyst production on the Hg content of soil around the plant,the soil mercury around a typical enterprise in Guizhou was studied.The pollution of Hg was evaluated by the geo-accumulation index method and potential ecological index method in soil.The results showed that the average value of soil Hg content was 1.58mg/kg,which exceeded the soil background value of Guizhou Province.The average value of geoaccumulation index was 3.07,which reached the level of heavy pollution.The average potential ecological risk index was 572.73,which was extremely strong ecological risk level.It is recommended to take effective measures to prevent the impact of Hg pollution on the surrounding soil.
