panty liners, and incontinence pads for evidence of PFAS,” writes the outlet.Fluorine was detected in 22 of them, or 48 percent of the products they looked at.
The determination of PFAS in food products and the environment involves a series of analytical techniques, including sampling, extraction, and analysis. Conventional methods, such as LC-MS/MS, are effective in PFAS analysis but are often expensive and not widely accessible. On the other hand, eme...
The types of makeup that contain PFAS are: Foundations Waterproof mascaras Lip products Lotions Cleansers Nail polish Shaving cream Eyeliner Eyeshadow PFAS might be listed on the ingredient list as PTFE (polytetrafluoroethylene), perfluorooctyl triethoxysilane, perfluorononyl dimethicone, perfluorodecalin,...
for 30 substances of all large public water systems (“PWS”) serving more than 10,000 people, and 800 representative PWS serving 10,000 or fewer people. Six PFAS compounds were included in the UCMR 3 contaminant list. Of these

PFAS has come into universal usage when invoking any chemical included in a family of fluorine-containing chemical compounds that are used by a nearly endless list of manufacturers producing a staggering number of products for a seemingly infinite number of applications in virtually all market and ...

The Stockholm Convention on Persistent Organic Pollutants (POPs), which began in 2001, is an important agreement for the elimination of environmental pollutants such as PFAS on a global scale. As part of this agreement, PFOS was added to the restricted list in 2009 and PFOA to the phase-out...
The EPA 537 method for analysis of PFAS in drinking water was updated in 2018 to include emerging PFAS in the list of compounds covered by the method. EPA 537.1 requires the use of a styrene divinylbenzene (SDVB) substrate for solid phas...
many industries rely on PFAS inputs for their products. Regulatory action is driving many companies to launch alternatives with the same high-performance characteristics. But that may be tricky given the list of banned PFAS classes, chemical blends and concentrations may expand in the fu...
