Rapidly rising levels of TFA ‘forever chemical’ alarm experts
Rapidly rising levels of TFA, a class of “forever chemical” thought to damage fertility and child development, are being found in drinking water, blood and rain, causing alarm among experts.
Studies from across the world are reporting sharp rises in TFA. A major source is F-gases, which were brought in to replace ozone-depleting CFCs in refrigeration, air conditioning, aerosol sprays and heat pumps. Pesticides, dyes and pharmaceuticals can also be sources.
“Everywhere you look it’s increasing. There’s no study where the concentration of TFA hasn’t increased,” said David Behringer, an environmental consultant who has studied TFA in rain for the German government.
