Sep 26, 2024 · Per- and polyfluoroalkyl substances (PFAS) are a large class of thousands of synthetic chemicals that are used throughout society. However, they are increasingly detected as environmental pollutants and some are linked to negative effects on human health.

Nov 1, 2023 · Per-and-polyfluoroalkyl substances (PFAS) are a collective name for a broad class of man-made chemicals of emerging concern that have recently been in the spotlight due to potential human and environmental health risks. While the public attention to PFAS is relatively new, the chemicals have been used globally since the 1940s.

The PFAS Rule regulates levels of perfluorooctanoic acid (PFOA), perfluorooctane sulfonic acid (PFOS), perfluorohexane sulfonic acid (PFHxS), perfluorononanoic acid (PFNA), hexafluoropropylene oxide dimer acid (HFPO-DA or GenX Chemicals), as well as mixtures of two

Sep 25, 2024 · Per- and polyfluoroalkyl substances (PFAS) are a group of chemicals used in some industries and consumer products. Workplace exposure to PFAS has been linked to cancer and other health effects. Firefighters and chemical manufacturing workers may be more exposed to PFAS than the general public.

Per- and polyfluoroalkyl substances (PFAS) are of concern because of their high persistence (or that of their degradation products) and their impacts on human and environmental health that are known or can be deduced from some well-studied PFAS.

DOE’s “Per-and polyfluoroalkyl substances (PFAS) Update” includes general information on PFAS, the Department’s PFAS mission statement, recent actions and ongoing efforts to address PFAS, additional PFAS resources and contact information.

Most people have been exposed to PFAS. Some PFAS chemicals can accumulate and can stay in the human body for long periods of time. The EPA is rapidly expanding the scientific foundation for understanding and managing risk from PFAS.

Feb 1, 2024 · Per- and Polyfluoroalkyl Substances (PFASs) are toxic, man-made, hazardous chemicals that have dangerous effects on the environment and our health. They are a large family of fluorinated chemicals that have partially or completely …

Recent EPA Actions on PFAS •Announced plans to revise effluent limitations guidelines for key industries using PFAS (August 2021) •Released Draft Method 1633, a laboratory method to test for 40 PFAS in wastewater, surface water, groundwater, soil, biosolids, sediment, landfill leachate and fish tissue (August 2021)

Oct 29, 2024 · PFAS, more commonly known as ‘forever chemicals’, are reshaping water regulations globally as authorities seek to gain a handle on their widespread use and harmful health effects.
