High levels of toxic ‘forever chemicals’ found off coast of southern England

Study of Channel finds levels of toxic Pfas in Solent at 13 times safe limits in some places, with much coming from treated sewage Scientists have found high levels of toxic Pfas, or “forever chemicals”, in soil, water and throughout the marine food chain in the UK’s Solent strait, including at protected environmental sites, according to a new study. In some samples, pollution was 13 times the safe threshold for coastal waters. Others, which were below legal limits for individual chemicals, failed tests for combined toxicity. The samples were taken from the Solent strait, which runs between the Isle of Wight and the mainland, forming part of the Channel. The chemicals are thought to have entered the environment from wastewater treatment plants, sewage outflows, historic landfills and nearby military sites. Researchers said their findings highlighted the need to monitor chemicals in combination and to make a blanket ban on Pfas part of the government’s water reform agenda. Prof Alex Ford, a biologist at the University of Portsmouth and one of the study’s authors, said: “If there was an oil spill in the Solent that industry would have to pay for the restoration of those h
