Elucidation of contamination sources for poly- and perfluoroalkyl substances (PFASs) on Svalbard (Norwegian Arctic) [PDF]

, 2018
A combination of local (i.e. firefighting training facilities) and remote sources (i.e., long-range transport) are assumed to be responsible for the occurrence of per- and polyfluoroalkyl substances (PFASs) in Svalbard (Norwegian Arctic).

Toxicity of Per- and Polyfluoroalkyl Substances and Their Substitutes to Terrestrial and Aquatic Invertebrates—A Review

Toxics
Per- and polyfluoroalkyl substances (PFASs) have been widely used in daily life but they cause certain impacts on the environment due to their unique carbon–fluorine chemical bonds that are difficult to degrade in the environment.

饮用水中全氟和多氟烷基物质的污染特征及管控

Jingshui jishu
【目的】全氟和多氟烷基物质(PFASs)被广泛应用于各种工业产品和日常消费品中，已成为受到广泛关注的持久性有机污染物。环境水体中已普遍检出PFASs,人体通过饮水摄入是PFASs主要暴露途径之一，开展饮用水中PFASs赋存特征研究对于PFASs的防控至关重要。【方法】本文论述了PFASs的种类，除了包含全氟烷基羧酸(PFCAs)和全氟烷基磺酸(PFSAs)两大类传统PFASs外，还包含了新型PFASs的典型类别，并从直接排放和间接迁移两方面，对饮用水中PFASs的污染来源进行分析 ...

Screening of PFASs in groundwater and surface water [PDF]

, 2016
Per- and polyfluoroalkyl substances (PFASs) are emerging organic pollutants characterized by their persistency, and bioaccumulation and toxicity potential. In this study, 26 PFASs were screened in 502 water samples originating from Swedish groundwater, surface water, sewage treatment plant (STP) effluents and landfill leachates.
