Per- and polyfluoroalkyl substances (PFAS[1] or PFASs[2]) are a group of synthetic organofluorine chemical compounds that have multiple fluorine atoms attached to an alkyl chain; there are 7 million such chemicals according to PubChem. [3] PFAS came into use after the invention of Teflon in 1938 to make fluoropolymer coatings and products that ...
An example of PFAS is the fluorinated polymer polytetrafluoroethylene (PTFE), which has been produced and marketed by DuPont under its trademark Teflon. GenX chemicals and perfluorobutanesulfonic acid (PFBS) are organofluorine chemicals used as a replacement for PFOA and PFOS.
A pizza box, for example, will have PFAS on the bottom. There’s actually some new data suggesting that PFAS are very prevalent in pesticides, and so, in fact, are being sprayed on to foods.
Microbac Laboratories, a Pennsylvania-based environmental, food and life sciences testing company, is one of many firms offering PFAS testing services to Midwestern customers, from public water ...
PFAS in contaminated soil and irrigation water can end up in food. The European Union and countries like Australia and New Zealand have already evaluated and established "tolerable daily intakes ...
Remediation of per- and polyfluoroalkyl substances refers to the destruction or removal of per- and polyfluoroalkyl substances (PFASs) from the environment. PFASs are a group of synthetic organofluorine compounds, used in diverse products such as non-stick cookware and firefighting foams, that have attracted great concern as persistent organic ...
Those include "increased cholesterol levels, decreased birth weights, decreased immune response to vaccines, increased blood pressure problems during pregnancy, increased risk of thyroid disease ...
Environment portal. Ecology portal. v. t. e. Persistent organic pollutants (POPs) are organic compounds that are resistant to degradation through chemical, biological, and photolytic processes. [1] They are toxic and adversely affect human health and the environment around the world. [1]
