Significant drop in levels of toxic 'forever' chemicals in England's rivers
Reported byBBC Science & Environment ↗·Sourced by Goodlede
Concentrations of PFOS and PFOA in English rivers have fallen by 30% and 29% respectively over the last decade, with levels in freshwater fish down 49%, following the ban of PFOS in 2010 and PFOA in 2020.
The chemicals remain in the environment at high absolute levels and will persist for decades; the decline reflects dilution and dispersal into the sea rather than permanent destruction.
