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.

Electrochemical degradation of perfluoroalkyl and polyfluoroalkyl substances (PFASs) in groundwater

Water Science and Technology, 2015
Abstract Perfluoroalkyl and polyfluoroalkyl substances (PFASs) represent hazardous pollutants and are frequently detected in the environment, e.g. in contaminated groundwater. PFASs are persistent to biodegradation and conventional oxidation processes such as ozonation.

Short-chain perfluoroalkyl acids: environmental concerns and a regulatory strategy under REACH

Environmental Sciences Europe, 2018
Background Short-chain PFASs (per- and polyfluoroalkyl substances) are widely used as alternatives to long-chain PFASs. Long-chain PFASs become gradually regulated under REACH (EC No.

Vertical Profiles, Sources, and Transport of PFASs in the Arctic Ocean

Environmental Science & Technology, 2017
The relative importance of atmospheric versus oceanic transport for poly- and perfluorinated alkyl substances (PFASs) reaching the Arctic Ocean is not well understood. Vertical profiles from the Central Arctic Ocean and shelf water, snow and meltwater samples were collected in 2012; 13 PFASs (C6-C12 PFCAs; C6, 8, 10 PFSAs; MeFOSAA and EtFOSAA; and FOSA)

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 ...

Scientists’ Statement on the Chemical Definition of PFASs

Environmental Science & Technology Letters
The undersigned are scientists with expertise in per- and polyfluoroalkyl substances (PFASs) and/or the management of chemicals. We assert that the Organization for Economic Co-operation and Development (OECD) definition of PFASs is scientifically grounded, unambiguous, and well suited to identify these chemicals. We are concerned that some individuals
