Toxin Levels in Fish Lead To Calls For UK-Wide Ban on Mercury Dental Fillings

Britain is facing mounting pressure to ban mercury dental fillings, one of the few countries yet to prevent the practice, as new data reveals alarming contamination levels in the nation's fish and shellfish. The Guardian: Mercury is a potent neurotoxin that can harm the nervous, digestive and immune systems, as well as the lungs, kidneys, skin and eyes, even at low levels of exposure. Its organic form, methylmercury, is particularly dangerous to unborn babies and can move through the food chain building up in insects, fish and birds. Britain is lagging behind the rest of the world on phasing out mercury dental fillings, with 43 countries having already banned mercury amalgam, including the EU, Sweden, Norway, Tanzania, Uganda, Indonesia and the Philippines. Northern Ireland will outlaw mercury fillings from 2035 but no such ban is planned in the rest of Britain. According to new analysis by the Rivers Trust and Wildlife and Countryside Link, more than 98% of fish and mussels tested in English rivers and coastal waters contain mercury above safety limits proposed by the EU, with more than half containing more than five times the recommended safe level.
