Researchers Blast ‘Forever Chemicals” into Oblivion With Plasma

/in , /by /Grist by Emily Pontecorvo

Christopher Sales is an environmental microbiologist, and until recently, his world was about harnessing the power of microorganisms to break down contaminants in the environment. But a resilient intruder that does not succumb to the same old tricks has shaken up the remediation community and led Sales to look outside of his field for a solution. It’s a chemical that’s been found in water, soil, and food all over the planet: PFAS.

PFAS (per- and polyfluoroalkyl substances) are a group of chemical compounds used in carpet, waterproof clothing, nonstick pans, and many other common products, that have gone unregulated and been dumped into the environment for decades.

Creating ‘Forever Chemicals’: A Guide to PFAS Companies (2)

The billion-dollar companies that made and used chemicals now popping up in water supplies around the country are switching to newer alternatives, but they haven’t escaped liabilities for historic environmental contamination.

The chemicals, known as per- and polyfluoroalkyl substances or PFAS, have become ubiquitous in everyday consumer goods as well as in specialized industrial applications. For some of the companies, including 3M Co. and the Chemours Co., liabilities from their PFAS operations have negatively affected the value of their stock.

What do you do about lab-made chemicals that are in 99% of people in the U.S. and have been linked to immune system problems and cancer? Whose bonds are so stable that they’re often called “forever chemicals“? Meet PFAS, a class of chemicals that some scientists call the next PCB or DDT. For consumers, they are best known in products like Scotchgard and Teflon.

California Will Check On ‘Forever Chemicals’ In Drinking Water. What You Need To Know

Over 75 years, a billion-dollar industry has grown up around a group of toxic chemicals that helps keep carpets clean, makes water roll off of camping equipment, and stops your food from sticking to frying pans. There are nearly 5,000 of these chemicals in a class called PFAS, for perfluoralkyl and polyfluoroalkyl substances. We’re just beginning to understand the risk they pose. What chemists know is that the tough carbon-fluorine bonds in these “forever chemicals” make them break down very slowly in the environment — posing a persistent risk to water supplies.  The Centers for Disease Control has profiled PFAS, which has been studied in people and in animals. Studies have linked to it developmental problems, thyroid disease, harm to the immune system, and impaired liver function.
