污染场地绿色修复和可持续管理逐渐成为国际上倡导的发展方向,修复过程对环境产生的影响日益受到重视。生命周期评估(LCA)作为一种可评估项目全过程环境影响的新兴技术,可以从污染场地自身环境改善的角度进行效益评估,同时解决污染场地修复工程本身可能在区域和全球尺度上产生的其他负面影响,在污染土壤、底泥、地下水修复管理决策中已有较多应用。从评估程序、评估模型、不确定性研究等方面对污染场地修复LCA进行论述,为中国污染场地绿色修复和可持续管理中使用LCA方法提供参考。
Green remediation and sustainable management of contaminated sites have been initiated worldwide in recent years,as the environmental impacts caused by remediation processes drawing more and more attentions.Being an innovative technology to evaluate overall environmental impacts of projects,LCA evaluates the effects of improving the contaminated sites’ environment.Besides,LCA assesses other negative impacts caused by remediation projects in both regional and global scales.The method has been applied in many remediation management cases of contaminated soil,sediment and groundwater.Herein,the studies of LCA on contaminated site remediation from the perspectives of procedures,modeling and uncertainties were reviewed,which could provide references for applying LCA on contaminated site green remediation and sustainable management in China.
