摘要
根据《中华人民共和国土壤污染防治法》,建立并公开《江苏省建设用地土壤污染风险管控和修复名录》(以下简称“名录”)。对2020—2022中江苏省纳入名录的116个污染地块开展系统性分析,结果表明:纳入名录的污染地块数量和面积与地区经济发展水平有关,南京、无锡、常州和苏州排名前列;土水复合污染地块占53%,其中64%的地块地下水最大污染深度大于同一地块土壤最大污染深度;共统计到167种污染物,重金属、石油烃和多环芳烃最为常见,约50%的污染物不在我国现行建设用地土壤及地下水污染评价标准中;已完成修复并移出名录的31个地块中,17%的污染土壤和25%的污染地下水采用原位修复技术。提出了完善土壤环境质量标准体系,探索土水协同治理修复模式,推进土壤污染绿色低碳修复等针对性的对策建议,为促进土壤、地下水环境管理和污染防治行业科学发展提供参考依据。
Accordingto Law of the People s Republic of China on the Prevention and Control of Soil Pollution,Jiangsu Province has established and publicly disclosed List of Risk Management and Remediation of Soil Pollution of Construction Land(hereinafter referred to as List).Systematic analysis on the pollution situation of 116 sites on the List showed that in terms of regional distribution,the number and area of contaminated land included in the list are related to the level of regional economic development,with Nanjing,Wuxi,Changzhou,and Suzhou ranking among the top.In terms of pollution media,53%of the sites have complex pollution of both soil and water and 64%of the plots have a deeper maximum depth of groundwater pollution compared to the maximum depth of soil pollution in the same plot.In terms of pollution factors,167 kinds of pollutants were counted,of which heavy metals,petroleum hydrocarbons and polycyclic aromatic hydrocarbons were the most common,and about 50%of the pollutants were not included in the current construction land soil and groundwater pollution assessment standards in China.In terms of remediation technologies,out of the 31 plots that have been repaired and removed from the Lists,17%of the contaminated soil and 25%of the contaminated groundwater were remediated using in-situ techniques.Based on the statistical characteristics of polluted sites listed in Jiangsu Province,targeted recommendations have been proposed,such as improving the soil environment standard system,exploring coordinated remediation mode for groundwater and soil,and speeding up green and low-carbon remediation of polluted soil,to promote scientific development of the soil and groundwater environmental management and pollution control industry.
