佛山市某陶瓷企业搬迁遗留场地调查及风险评估
|
摘要
以佛山市某陶瓷厂搬迁遗留场地为研究对象,以《场地环境调查技术导则》(HJ25.1-2014)等文件为依据进行场地调查及风险评估。结果表明:土壤调查结果满足《土壤重金属风险评价筛选值珠江三角洲》(DB44/T1415-2014)及《上海市场地土壤环境健康风险评估筛选值(试行)》等居住用地风险筛选值要求,不需进行土壤风险评估;场地内地下水氨氮、总大肠杆菌超标为地下水污染现状所致,不影响本场地的后续开发需求。
The environmental site investigation and health risk assessment were performed for the remaining site of a relocated ceramic factory according to Technical Guidelines for Risk Assessment of Contaminated Sites(HJ25.1-2014).The results showed that the soil survey results met the requirements of residential land risk screening value such as "Screening Value of Soil Heavy Metal Risk Assessment in the Pearl River Delta(DB44/T1415-2014)" and "Screening value of Shanghai soil environmental health risk assessment(trial)" and there was no need for soil risk assessment. The results also showed that the excess ammonia nitrogen and total escherichia coli in the water in the mainland of the site were caused by groundwater pollution, which would not affect the subsequent development requirements of the site.
