Since contamination was first discovered in the drinking water of another resident in 2022, dangerous levels of a group of compounds known as PFAS, or “forever chemicals,” have been found in more than 300 private wells in Westminster.
Indeed, the carbon-fluorine bond which joins PFAS chemicals together is one of the strongest known to science. For this reason, it may take a thousand years or more for PFAS to decompose in the environment, meaning they will undoubtedly outlive the products whic...
PFAs, or per- and polyfluoroalkyl substances, to give them their full name, are a subset of chemicals which are infamous for their extremely long half-lives. This has led to them being dubbed “forever chemicals”, since many of them can persist in the natural environment for centuries or ...

“There is nothing safe and nothing good about PFAS,″ said Connecticut Senator Richard Blumenthal, who introduced the cosmetics bill with Senator Susan Collins of Maine. “These chemicals are a menace hidden in plain sight that people literally display on their faces every day.″ ...
Added chemicals can include highly toxic compounds like carcinogens, endocrine disrupters, and neurotoxicants, or chemicals with reproductive effects, such as BPAs, phthalates, bisphenols, and per- and polyfluoroalkyl substances (PFAS). A series of studies has begun bearing out the human toll of ...

Researchers at ETH Zurich have developed a new way to break down a dangerous subgroup of PFAS known as PFOS. With the help of nanoparticles and ultrasound, piezocatalysis could offer an effective alternative to existing processes in the future. What do firefighting foam, non-stick cookware, water...
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 lab. ...
However, industry reworked the chemicals by making them into 4- and 6-carbon chains — today over 9,000 different PFAS exist,according to the CDC. Experts say these newer versions appear to have many of the samedangerous health effects as the 8-chain PFAS, leaving consumers and the environme...
