It has recently been shown that even low doses of mercury may cause toxicity. Increased release of mercury from dental amalgam restorations after exposure to electromagnetic fields has been confirmed by different researchers as well as my team. It has also been reported that the increased mercury release after exposure to electromagnetic fields may pose risks for the hypersensitive proportion of the population, children and pregnant women. Although it was previously believed that the amount of mercury released from dental amalgam cannot be hazardous, new findings indicate that mercury, even at low doses, may cause toxicity.  By the way, now we are looking for the data showing mercury may cause synergistic effects with other heavy metals. Thank you very much in advance.
