Toxin levels in fish lead to calls for UK-wide ban on mercury dental fillings
Recent findings show that over 98% of fish and mussels in English waters contain mercury levels exceeding EU safety limits, prompting urgent calls for the UK to ban mercury dental fillings. This is significant because mercury is a harmful neurotoxin that poses serious health risks, affecting various bodily systems even at low exposure levels. As one of the few countries still allowing these fillings, the UK faces increasing pressure to protect public health and align with safety standards.
