New science on PFAS chemicals should mobilize our senators
News
19 Sep 2019 | The Fayetteville Observer
A peer-reviewed study, published this month in the prestigious Chemical Engineeri Journal, found short-chain PFAS chemicals, like GenX, are more widely detected, more persistent, and more mobile than long-chain PFAS chemicals they were designed to replace--such as PFOA and PFOS... This is profound news considering PFAS chemical makers, like Chemours, continue to claim GenX and other short-chain PFAS are safer replacements.
