2024年10月3日 · How to better and more efficiently detect and measure PFAS in our air, water, soil, and fish and wildlife; How much people are exposed to PFAS; How harmful PFAS are to people and the environment; How to remove PFAS from drinking water; How to manage and dispose of PFAS

Per- and polyfluoroalkyl substances are a group of synthetic organofluorine chemical compounds that have multiple fluorine atoms attached to an alkyl chain. Different organizations use different definitions for PFAS, leading to estimates of between 8,000 and 7 …

2025年3月6日 · It has recently implemented abatment technologies making sustainable the manufacturing of FPs by drastically reducing emissions of nonpolymeric PFAS residues, as both the fluorinated gas and aqueous emissions (lower than 0.009% by the end of 2024 and lower than 0.003% by 2030 ) as well as in improving their manufacturing processes without using ...

2016年10月7日 · Perfluorinated chemicals is a term that some scientists use to refer to the group of toxic chemicals that includes PFOA and PFOS and other per- and polyfluoroalkyl substances (PFASs).

2024年9月26日 · PFAS have a wide range of different physical and chemical properties. They can be gases, liquids, or solid high-molecular weight polymers. Some PFAS are described as long-chain or short-chain, but this does not cover all of the different kinds of structures that are present in the PFAS class, which is very diverse.

2024年6月26日 · The undisclosed and ubiquitous use of perfluoroalkyl and polyfluoroalkyl substances (PFAS) in consumer products has led to a growing issue of environmental pollution, particularly within the solid waste community, where the fate of volatile (neutral) PFAS in landfilled refuse is not well understood.

2025年1月8日 · This study provides theoretical insights into the gas-phase oxidation mechanisms of PFAS, their role in nanoparticle formation, and their ecological effects, contributing to a deeper understanding of their hazardous impacts.

2024年8月27日 · 現行的全歐盟共通法規中，與PFAS有關的部份仍然只規範特定PFAS物質，PFOA和PFOS在2020年就被列入歐盟持久性有機污染物規範（EU Persistent Organic Pollutants Regulation）中，PFHxS預計在2023年也將被列管。規範原則簡單講就是除了特定用途之外，禁止生產、流通、販售 ...

Melting and boiling point information refers to the temperature of phase transitions of pure compounds. These properties determine whether a specific pure PFAS compound will exist as a liquid, solid, or gas under typical environmental temperatures. These data can …

2022年12月21日 · 全氟烷基和多氟烷基物質 (PFAS) 是一類含有至少一個完全氟化碳原子的氟化有機化學品。 全氟辛酸 (PFOA) 和全氟辛烷磺酸 (PFOS) 是在 1940 年代和 1950 年代開發的。 很快，這些化學品被用於開發具有不粘和防污特性的產品。 這些基於 PFAS 的化學品還廣泛用於其他應用，從消防泡沫到戶外織物處理。 在 70 年代後期，這些化學物質被確定為對人類健康有害，高劑量與哺乳動物的生殖、致癌和其他問題有關。 PFAS 非常穩定，在環境中被稱為“持久性”，因 …
