Contamination can also come from the presence of PFAS in food packaging, stain-resistant textiles and thousands of consumer products such as cookware, tampons and cosmetics.
It's how the cookware gets its waxy texture. It was more than two decades ago that Bilott first began investigating reports of wide-ranging serious illness — various cancers, birth defects ...
Fire-retardant foam, which contained PFAS compounds for decades, often found use at military bases and airstrips, causing costly pollution to nearby water sources. The U.S. Department of Defense ...
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 pollutants.
The Devil We Know is a 2018 investigative documentary film by director Stephanie Soechtig regarding allegations of health hazards from perfluorooctanoic acid (PFOA, also known as C8), a key ingredient used in manufacturing Teflon, and DuPont's potential responsibility.
The type of PFAS remediation technology selected is often a reflection of the PFAS contamination levels and the PFAS signature (i.e. the combination of short- and long-chain PFAS substances present) in conjunction with the site-specific water chemistry and cross contaminants present in the liquid stream.
What are forever chemicals, or PFAs? “Forever chemicals are a class of chemicals known as PFAs, or Per- and polyfluoroalkyl substances,” says Emily Scarr , program director of Maryland’s ...
In 2020, the European Food Safety Authority added PFNA in its revised safety threshold for PFAS that accumulate in the body. They set the threshold for a group of four PFAS of a tolerable weekly intake of 4.4 nanograms per kilogram of body weight per week.
