全氟辛烷磺酰基化合物水生生态风险和人体健康风险评价

全氟辛烷磺酰基化合物（Perfluorooctanesulfonate，PFOS ）广泛用于工农业生产，PFOS可通过不同的迁移路径迁移到大气、水和土壤等环境介质中。研究表明，PFOS是一种新的持久性有机物污染物，具有毒性，可通过食物链富集。2006年PFOS被欧盟议会和部长理事会列为限制销售和使用物质。本文引用中国沿海、亚洲海域和美国部分水域的PFOS暴露浓度数据，采用商值法对PFOS的水生生态环境风险进行了评价，建立了5 种因素水平的数学模型，并应用此数学模型对PFOS的人体健康风险进行了评价。结果表明我国部分地区和亚洲沿海PFOS的水生生态风险低于美国水域，亚洲沿海、我国部分地区以及美国部分城市水体中PFOS个人风险大小依次是我国部分地区<亚洲沿海<美国部分城市。

ECOLOGICAL AND HUMAN HEALTH RISK ASSESSMENT OF PERFLUOROOCTANESULFONATE(PFOS)

Perfluorooctanesulfonate(PFOS) is a kind of surfactant,developed and manufactured by 3M Company,USA,and is widely used in industry and agriculture.PFOS can migrate into the air,aquatic area and soil environment media in different ways.Investigation demonstrated that PFOS was toxic and was listed as an emerging persistent organic pollutant(POP),which can be bioaccumulated through food-chain.In 2006,the European parliament and the council passed regulations and administrative provisions of the Member States relating to restrictions on the marketing and use of certain dangerous substances and preparations(perfluorooctane sulfonates).Based on the existing data of PFOS levels from China and Asia coast areas as well as from the aquatic environment of the USA,the authors performed ecological risk assessment(ERA) of PFOS using hazard quotient method.The result showed that the ecological risk of PFOS in China and Asia water area is lower than that of US.A mathematical model is established and applied for human health risk assessment of PFOS,and the hazardous sequence of PFOS is parts of China area
