Toxic 'Forever Chemicals' Plummet in English Rivers
12 Nov
Summary
- Toxic forever chemicals PFOS and PFOA levels dropped significantly in English rivers.
- The decline is attributed to stricter regulations on the use of these harmful chemicals.
- Fish in freshwater environments saw a substantial 49% decrease in these chemicals.
Levels of two key toxic "forever chemicals," PFOS and PFOA, in England's rivers have decreased by approximately 30% over the last ten years. This marked reduction is a direct result of stricter regulations implemented on their use, spurred by growing evidence of their detrimental health and environmental impacts. The concentrations of these chemicals in freshwater fish have fallen by an even more significant 49%.
Despite this progress, environmental authorities highlight the ongoing challenge posed by thousands of other per- and polyfluoroalkyl substances (PFAS). These chemicals, known for their persistence, are still widely used in various products. The Environment Agency is expanding its testing to monitor around 60 other PFAS compounds to better understand contamination nationwide.
While the concentration of PFOS and PFOA has decreased, the overall environmental load may remain unchanged due to their slow natural breakdown. Experts advocate for regulating all PFAS compounds collectively rather than individually, a stance met with opposition from the chemical industry. Efforts are underway to identify and hold polluters accountable for past damage.
