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...
PFAS是(Per-and polyfluoroalkyl substances)的简称,中文名:全氟烷基和多氟烷基物质,是一系列合成有机氟化物的总称,是指至少含有一个全氟化碳原子的有机化合物(即至少含有一个-CF2-或-CF3脂肪链结构单元)。全氟烷基和多氟烷基物质(PFAS)包括全氟辛酸(PFOA)、全氟辛基磺酸(PFOS)及其他众多化合物。根据其结构...
Per- and polyfluoroalkyl substances (PFASs) are a ubiquitous group of persistent chemicals distributed globally in the environment. Skin aging is a notorious process that is prematurely induced by the interaction between endogenous and exogenous factors, including exposure to environmental chemicals. The...
Per- and polyfluoroalkyl substances (PFAS) are synthetic, organic chemicals that resist environmental breakdown. The properties that made PFAS into an industrial success also led to their persistence and bioaccumulation. As PFAS were widely used for many decades their presence is evident globally, and...
Per- and polyfluoroalkyl substances (PFAS) are persistent and bioaccumulative pollutants that can easily accumulate in soil, posing a threat to environment and human health. Current PFAS degradation processes often suffer from low efficiency, high energy and water consumption, or lack of generality. ...
PFAS Per-and polyfluoroalkyl substance 试验 欧盟REACH法规对PFAS的限制: 1、物质、混合物或物品中C9-C14 PFCAs及其盐类的总和<25 ppb,C9-C14 PFCAs相关物质的总和<260ppb。 2、不得制造或作为物质投放市场。用于物质的成分、混合物、物品: i.任意目标PFAS物质<25ppb(不含PFASs聚合物);...
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) are commonly used in proton exchange membrane fuel cells due to their high stability and resistance. These ionomers act as binding agents and their hydrophobic effect helps to remove excess water from the gas diffusion layer. Their proton conductivity and...
