阅读Per- and polyfluoroalkyl substances (PFAS) are man-made chemicals used since the 1940s to create items ranging from cleaning products to food packaging and paint. According to the Centers for Disease Control and Prevention, the chemicals can increase cancer risk and affect children's physical...
Per- and polyfluoroalkyl substances (PFASs) are a group of thousands of manmade chemicals widely used in consumer products and industrial processes. Toxicological studies have suggested that exposure to PFASs may lead to several adverse effects, including infertility and cancer development. In light...
全氟化合物,英文名称 Perfluoro and polyfluoroalkyl substances,或者 Perfluorinated and polyfluorinated alkyl substances,也被称为 Perfluoroalkyl chemicals,简称 PFAS。 全氟化合物是一类具有重要应用价值的有机化合物,其脂肪烃骨架的氢原子被氟原子取代。全氟羧酸(Perfluorocarboxylic acids,PFCA)是脂肪酸 (Fatty acid...
Per-and polyfluoroalkyl substances(全氟烷基和多氟烷基物质)是一系列的合成有机氟化物的总称,可以根据其结构不同进行分组,可以是气体、液体或固体的高分子聚合物。已知的PFAS类化合物近5000种,常见的有:PFOA、PFOS、C9-C14PFCAs、 PFHxA 、PFHxS等。 PFAS 具有独特的物理特性,例如:防水、防油脂、减少摩擦力、高...
At the global level, the Stockholm Convention on persistent organic pollutants has identified certain Per- and polyfluoroalkyl substances (PFAS) as priority for further assessment due to their persistent, bioaccumulative, and toxic characteristics. In the present study, we adopted a state-of-the-art...
中国的一些研究团队正在该领域投入更大的关注，1月12日，《欧洲环境科学》（Environmental Sciences Europe）在线发表了由清华大学环境学院环境模拟与污染控制国家重点联合实验室、新兴有机污染物控制北京市重点实验室副教授黄俊团队完成的一项成果，题为“Per- and polyfluoroalkyl substances (PFASs) in Chinese drinking...
Per- and polyfluoroalkyl substances (PFAS) have long been used in manufacturing to make everyday items resistant to extreme temperatures, reduce friction, and repel oil, water, grease, and stains. As global governmental bodies promulgate PFAS laws and regulations, Sidley has dedicated lawyers ...
Per- and polyfluoroalkyl substances (PFAS) belong to a continuously expanding family of thousands of man-made chemical pollutants. The amphiphilic ability of PFAS has led to the manufacturing of PFAS in oils and water-resistant industrial and consumer products such as firefighting foams, cleaners, ...
Per- and Polyfluoroalkyl Substances (PFAS) are manufactured chemical compounds containing carbon-fluorine bonds, which are one of the strongest chemical bonds that break down very slowly resulting in environmental persistence and biological accumulation. PFAS use is commonly associated with commercial ...
Per- and polyfluoroalkyl substances (PFAS), commonly referred to as “forever chemicals” raise significant concerns due to their persistence, bi
