PFAS were originally developed to help extinguish large petroleum fires. Now, they have many more applications, but are also polluting the environment.(Image credit: Shutterstock) Perfluoroalkyl and polyfluoroalkyl substances, or PFAS, are synthetic chemicals found in many products, including food packa...
Dubbed “forever chemicals,” PFAS chemicals don't break down easily over time and dissolve in water. Because of that, some scientists are concerned that these chemicals could build to levels that could harm the environment -- and your body. While there are studies that show evidence of this,...
故选C。 C PFAS are found in nonstick pans, water-proof fabrics and food packaging. They're called forever chemicals because of their ability to stick around and not break down. Now, using a bit of heat and two relatively common compounds, researchers have degraded (降解) the chemical in ...
The EPA hasset out to regulatesome older-generation chemicals generally found in imported products. Those have also beenbanned in the European Unionand phased out by major U.S. manufacturers, often replaced by newer-generation PFAS, which leave the body more swiftly and are less likely to b...
PFAS were found in the majority of the straws tested and were most common in those made from paper and bamboo. They were not found only in steel straws tested. PFAS are used to make everyday products, from outdoor clothing to non-stick pans, resistant (抵抗 to water, heat and stains....
Most PFAS detected in the environment were found to have a HQ risk value of <1 meaning their reported concentrations are below their predicted no effect concentration. This indicates many reported toxic effects of PFAS are, theoretically, unlikely to occur outside the laboratory. However, lack of...

Industrial chemicals found in the Tennessee River are PFAS (per-and polyfluorinated substances), mercury, PCBs (polychlorinated biphenyls), and corrosion inhibitors. These chemicals are often non-biodegradable, can move through soil into waterways, and last in the environment for decades to hundreds of...

PFAS are potentially harmful chemicals that can be found in common, everyday products and most drinking water. They are known as "forever chemicals" because they do not break down over time, and health leaders across the country are concerned about the negative effects of long-term exposure. R...
