A new study reveals that PFAS re-emit into the air from crashing ocean waves at levels comparable to or greater than other sources, establishing a cyclical transport process for these 'forever chemicals' between land and sea.

Field experiments across the Atlantic Ocean conducted by co-authors Bo Sha, Post-doc at the Department of Environmental Science and Jana Johansson, former Researcher at the Department of Environmental Science, currently at Linköping University, showed PFAS concentrations in air particles surpassing seawater concentrations by over 100,000 times. Subsequent global modeling estimated the re-emission, atmospheric transport, and deposition of PFAS to land.
"In Denmark, scientists have compiled compelling evidence indicating that the sea serves as the primary source of PFAS along their west coast," explained Matthew Salter, Researcher at the Department of Environmental Science and co-author of the study."This aligns with our expectations, as our study predicts that coastal regions bear the greatest impact."
The frigid Arctic Ocean is far removed from the places most people live, but even so, 'forever chemicals' reach this remote landscape. Now, research suggests that per- and polyfluoroalkyl ...

PFAS in blood are ubiquitous -- and they are associated with an increased risk of cardiovascular diseasesResearchers provide evidence that traces of the widely used PFAS chemicals in human blood are associated with unfavorable lipid profiles and thus with an increased risk of cardiovascular diseases. The findings are based on data from more than 2,500 adults. PFAS were detectable in the blood of nearly all study participants.
