摘　　要：以某染纱厂场地为研究对象,在污染识别的基础上,布设了土壤采样点23个、地下水监测井9个,采集72个土壤样品和9个地下水样品,监测分析了pH值、重金属、石油烃、挥发性有机化合物和半挥发性有机化合物在土壤和地下水中的含量分布。结果表明:该地块原厂后整理车间和染料库所在区域土壤和地下水受到不同程度污染;土壤中超标污染物为六价铬,地下水中超标污染物为氯苯;对初步环境调查筛选出的具有较高环境风险的区域,需要进一步开展详细调查和风险评估工作,并制定和实施必要的环境管理措施。On the basis of the preliminary identification of the contaminated site of a yarn dyeing factory,23 soil sampling points and 9 groundwater monitoring wells were decided,and 72 soil samples and 9 groundwater samples were collected.The concentration distribution was studied of pH value,heavy metals,petroleum hydrocarbons,volatile organic compounds(VOCs)and semi volatile organic compounds(SVOCs)in the soil and groundwater.Results showed that:the soil and groundwater in the finishing workshop and dye storage area were polluted to varying degrees;the pollutants in the soil were Cr(VI),and the pollutants in groundwater were chlorobenzene;to protect the health of future residents,detailed site investigation and health risk assessment should be undertaken in the high-risk areas and sound management measures should be conducted.
