摘要
开展地块后期管理是保障人居安全及彻底打赢土壤污染防治攻坚战的关键一环。针对污染地块调查与风险评估、修复与风险管控、效果评估各阶段存在的不确定性,以及修复后地块存在污染物浓度反弹和风险管控措施失效等可能风险,有必要开展污染地块修复和风险管控后期管理研究。为此,基于欧美国家污染地块管理经验,综合考虑我国污染地块环境管理要求,确定了需开展后期管理的地块类型,分析了后期管理过程中长期监测、运行维护、制度控制及回顾性评估4种措施的重要作用,初步构建了污染地块修复和风险管控后期管理框架体系,明确了长期监测对象与目的、监测点位、监测指标、监测频次与周期,运行维护内容,制度控制措施,回顾性评估要求及后期管理的终止条件。实施后期管理是贯彻落实《中华人民共和国土壤污染防治法》的重要体现,将为污染地块修复和风险管控后的安全再利用提供重要保障。
The post-remediation management is a critical step of protecting the health of people and realizing the goals set by“the Fight of Preventing and Controlling Soil Pollution”.Considering the uncertainties associated with different stages of risk management and remediation of soil contamination,and the possibilities of rebound in pollutants concentrations or the failure of risk management measures,it is essential to study the effects of different post-remediation management practices.In this study,we comprehensively considered the current environmental management requirements of contaminated sites in China,and analyzed the effect of four different management measures including long-term monitoring,operation and maintenance,institutional control,and retrospective review.Comparisons were made between common practices in our country and those in western countries.Our study established a framework for remediation and risk management of contaminated sites by outlining the general requirements to determine monitoring locations,target pollutants,duration and frequency of monitoring,facilities that require operation and maintenance,adequacy of institutional control,the overall requirements for retrospective review and terminal condition.The implementation of post-remediation management constitutes an important aspect of the Soil Pollution Prevention and Control Law of the People’s Republic of China,and will underpin the safety reuse of contaminated sites after remediation and risk management.
