摘要
蒸气入侵(VI)是最有可能导致人体健康风险的暴露途径,石油烃类蒸气入侵(PVI)是污染物为挥发性石油烃(PHC)时的一种特定VI类型,与其他类型VI的最重要区别在于PHC在包气带传输过程中会因好氧生物降解而迅速衰减,从而显著降低PVI风险发生的可能性。文章梳理和总结了PVI的概念、机理、筛选与调查、模型、风险评估与管控等方面的相关研究成果并进行了展望,以期为PVI研究以及PVI场地调查、风险评估与管控等实践工作提供借鉴和参考。
Vapor intrusion(VI)is the exposure pathway most likely to cause human health risks.Petroleum hydrocarbon vapor intrusion(PVI)is a specific type of VI when the contaminant is volatile petroleum hydrocarbons(PHC),and the most important difference from other types of VI is that PHC will rapidly attenuated due to aerobic biodegradation during transport in the vadose zone,thereby significantly reducing the possibility of PVI risks.Relevant research results on the concept,mechanism,screening and investigation,modeling,risk assessment and control of PVI are summarized,and possible future research directions are prospected,in order to provide reference for PVI research and practical work on PVI site investigation,risk assessment and control.
