【摘要】 近年来,随着新兴产业的快速发展,一些新型污染物带来的环境问题日益引起关注。全氟辛烷磺酸(PFOS)类物质因其优良的特性而被一些新兴产业广泛应用,但其环境持久性和潜在的毒性在2000年后引起科学界和政府的广泛重视。随着发达国家管控措施的出台,其部分产能转入中国,使得中国政府亟需制定有针对性的管理措施。本文基于PFOS类物质在中国的生产与使用情况,对PFOS排放源进行了识别与分类,分析了2010年的排放水平及其与工业化程度的关系。结合PFOS在各环境介质中的暴露水平,分析了PFOS经源排放进入环境的途径、多介质传输过程及其与区域产业布局的关系。提出针对新型污染物的管理对策建议。更多还原

【Abstract】 With the rapid development of emerging industries in China, a series of environmental problems caused by emerging pollutants have attracted attention. Perfluorooctane sulfonate (PFOS) and related substances are synthetic chemicals manufactured for their desirable properties, and have been widely used in various consumer products and emerging industrial processes. Due to their persistent, bioaccumulative and toxic attributes, PFOS-related chemicals have attracted scientific, political and regulatory interests since 2000. While the production and use of PFOS have been restricted or eliminated in most developed countries, PFOS and related substances are still manufactured and used in relatively large quantities in China. Therefore, specific measures or regulations for managing PFOS-related activities are in great need. In the present study, emission sources of PFOS were identified and classified based on the production and use status of PFOS-related chemicals in China. PFOS emission loads in 2010 were estimated and their relationship with industrialization was analyzed. The exposures of PFOS in multiple environmental media were summarized. The pathway for PFOS entry into environment from the emission sources, its transfer processes in multimedia environment, and the relationship with industrial layout were discussed. Suggestions for risk assessment and management of such emerging pollutants as PFOS in China were provided.更多还原
