电镀场地土壤污染现状调查及分析研究

Investigation and Analysis of Soil Pollution in an Electroplating Site

对某电镀场地土壤环境进行初步调查研究,针对可能涉及到的重金属污染物(砷、镉、铬(六价)、铜、铅、汞、镍)、挥发性有机物及部分半挥发性有机物进行布点采样与样品采集,共布设6个土壤取样点位和2个地下水取样点位。分析结果表明,该场地土壤重金属及挥发和半挥发性污染物浓度未超过《土壤环境质量建设用地土壤污染风险管控标准》(GB 36600—2018)标准第二类用地筛选值标准,不属于污染地块,无需开展进一步场地土壤环境详细调查及健康风险评估工作。

A preliminary investigation was conducted on the soil environment of an electroplating site.Point sampling and sample collection were carried out for possible heavy metal pollutants(arsenic,cadmium,chromium(hexavalent),copper,lead,mercury,nickel),volatile organic compounds and some semi volatile organic compounds.A total of 6 soil sampling points and 2 groundwater sampling points were arranged.The analysis results show that the concentration of heavy metals and volatile and semi-volatile pollutants in the soil of the site does not exceed the screening value standard of class II Land in“standard for soil environmental quality control of soil pollution risk of construction land”(GB 36600—2018),which does not belong to the polluted land,so there is no need to carry out further detailed investigation of the site soil environment and health risk assessment.
