水体中全氟化合物的环境风险及其去除技术
Environmental Risk and the Removal Technology of Perfluorochemicals in Water Body
摘要
Abstract
[Objective]per-and polyfluoroalkyl substances(PFASs)are a kind of organic pollutants with refractory,bioaccumulative,and biotoxicity,have been frequently detected in environments and organisms and attracted a great attention due to their ecological risks.Therefore,it is crucial to assess the environmental risks associated with PFASs and establish effective technologies for PFASs removal.[Methods]This paper reviews the distribution of PFASs in water bodies in China,summarizes their toxicity to microorganisms,plants,animals,and humans,and provided an overview of the main PFASs removal technologies:physical process,biological process,and chemical process.Physical process mainly focuses on adsorption and membrane separation processes;while the biological process primarily targetes microbial removal;Chemical process includes thermochemical,electrochemical,sonochemical,plasma,advanced oxidation process,semiconductor photocatalysis,and advanced reduction processes.The paper also discusses the advantages and limitations of the above techniques.[Results]The biological process remains in the developmental stage,while physical process are hindered by the issue of secondary pollution.Chemical process,in contrast,offer high mineralization rates and short degradation times.Among these,advanced reduction process shows promising potential for further research.However,chemical method are primarily confined to laboratory-scale studies,and the associated degradation costs remain high.[Conclusion]PFASs are ubiquitously present in water bodies,posing notable biotoxicity risks to organisms and humans.Current degradation technologies exhibit certain limitations.A holistic approach that integrates multiple degradation method,leveraging the strengths of each technique,can improve degradation efficiency and reduce the toxicity of PFASs degradation products,this integrates strategy offers valuable insights for the removal and control of PFASs in environmental settings.关键词
