It is commonly referred to as the main harmful PFAS chemical and PFOA is responsible for many of the negative health effects commonly associated with 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 ...
The so-called “forever chemicals” − a name attributed to PFAS' centuries-long half-life − are ubiquitous: In addition to drinking water, they are found in everything from non-stick ...
In 2024, a worldwide study of 45,000 groundwater samples found that 31% of samples contained levels of PFAS that were harmful to human health; these samples were taken from areas not near any obvious source of contamination. [52] Soil is also contaminated and the chemicals have been found in remote areas such as Antarctica. [53]
Not all PFAS are 'forever' chemicals One common mistake is the overarching use of “forever chemicals” to label PFAS, said Stapleton. Some PFAS can last incredibly long in the environment.
There is a growing body of research investigating the health effects of PFOS in humans and animals, including the reproductive, developmental, liver, kidney, thyroid, and immunological effects. [42] According to a 2002 report by the Environmental Directorate of the OECD , "PFOS is persistent, bioaccumulative, and toxic to mammalian species."
Story at a glance A group of potentially harmful chemicals called per- and polyfluoroalkyl substances (PFAS) have repeatedly cropped up in headlines. But the sheer number of chemicals in this ...
A new EU drinking water directive issued in 2020 adopted PFAS limit values. The limit values are 0.1 μg/L for the sum of 20 PFASs including PFHxS, and 0.5 μg/L for the sum of all PFASs. This directive is binding for all EU member nations. It is a minimum directive, and member states can elect to adopt stricter regulations. [19]
