云南会泽产业园区宝云片区土壤重金属现状评价及变化趋势分析

The Evaluation and Trend Analysis of the Present Status of the Heavy Metals in Soil in the Baoyun Area in the Huize County Industrial Park,Yunnan

依据2008、2014、2017、2019和2021年土壤监测资料,选取相同监测点位的监测数据对云南会泽产业园区宝云片区土壤重金属现状及变化趋势进行分析评价。结果显示,园区运行以来土壤中重金属镉、汞、砷、铜、铅、铬、镍等含量无较大变化,均能达到《GB 36600—2018土壤环境质量建设用地土壤污染风险管控标准(试行)》中第二类用地的筛选值和《GB 15618—2018土壤环境质量农用地土壤污染风险管控标准(试行)》中的筛选值要求,对园区土壤环境的累积影响不大。

The present status of the heavy metals in soil in the Baoyun area in Huize County industrial park were evaluated according to the soil monitoring data of 2008,2014,2017,2019,and 2021 using the same monitoring sites.The results showed that there were no significant variate of cadmium,mercury,arsenic,copper,lead,chromium,and nickel in the soil of the park since it has been open.Their concentrations could all meet the risk screening values for the second kind development land from“Soil environmental quality–Risk control standard for soil contamination of development land(GB 36600—2018)and the risk screening values from” Soil environmental quality–Risk control standard for soil contamination of agriculture land(GB 15618—2018),which indicated that these heavy metals had no critical impacts on the soil quality in the area.
