Some PFAS chemicals are declining in English rivers but others are appearing | New Scientist (www.newscientist.com)

The concentration of two of the most well-studied PFAS forever chemicals are showing a strong downward trend in English rivers. The finding adds to a mixed story for the power of global restrictions.

The levels of perfluorooctanesulfonic acid (PFOS) and perfluorooctanoic acid (PFOA) in English rivers have fallen by 30 per cent and 29 per cent, respectively, over the past decade, according to a new report by scientists at the Environment Agency (EA), a UK government green regulator.

Both of these human-made chemicals take a long time to break down in the environment. The International Agency for Research on Cancer recently designated PFOA as carcinogenic to humans, and both forever chemicals have been linked to reproductive health and developmental impacts as well as other serious health issues.

What environmentalists say: "quit using chemicals like Teflon that have the dangerous property of taking a long time to break down"

What chemical companies hear: "tweak the formulations to produce new chemicals that aren't regulated against but still have the same useful property of taking a long time to break down"
