摘　　要：以河北省石家庄市井陉县某铬污染场地为例,根据HJ 25.2—2014《污染场地风险评估技术导则》进行场地现状调查及风险评价。结果表明:该场地主要污染区域集中在铬渣堆场、浸取车间和转化车间3个区域,属于重度污染区域,其总铬和Cr^(6+)含量最高分别达到69 500,68 300 mg/kg。该场地在开发前需进行场地修复,针对场地不同污染状况,高浓度和低浓度铬污染土壤分别建议采用化学淋洗法和化学还原-固化稳定化法处理。The environmental site investigation and risk assessment were performed for a chromium contaminated soil in Jingxing County,Shijiazhuang,according to Technical Guidelines for Risk Assessment of Contaminated Sites（ HJ 25. 3—2014）. The results showed that the main pollution area of this area focused on the chromium slag yard,leaching workshop and workshop,which belonged to the heavily polluted area. And the highest total chromium concentrations and hexavalent chromium concentrations of the soil in the chromium contaminated sites was 69 500,68 300 mg/kg,respectively. Therefore the site remediation should be conducted to protect human health. Based on the pollution status of different sites,chromium contaminated soils of high and low concentrations were suggested to be remediated by chemical leaching method and reductionsolidification/stabilization method for removing chromium,respectively.
