Abstract

According to the World Health Organization (WHO), factors such as growing electricity demand, ever-advancing technologies and changes in social behaviour have led to steadily increasing exposure to man-made electromagnetic fields.  Dental amalgam fillings are among the major sources of exposure to elemental mercury vapour in the general population. Although it was previously believed that low levels are mercury (i.g. release of mercury from dental amalgam) is not hazardous, now numerous data indicate that even very low doses of mercury cause toxicity. There are some evidence indicating that perinatal exposure to mercury is significantly associated with an increased risk of developmental disorders such as autism spectrum disorders (ASD) and attention-deficit hyperactivity disorder (ADHD). Furthermore, mercury can decrease the levels of neurotransmitters dopamine, serotonin, noreprenephrine, and acetylcholine in the brain and cause neurological problems. On the other hand, a strong positive correlation between maternal and cord blood mercury levels is found in some studies. We have previously shown that exposure to MRI or microwave radiation emitted by common mobile phones can lead to increased release of mercury from dental amalgam fillings. Moreover, when we investigated the effects of MRI machines with stronger magnetic fields, our previous findings were confirmed. As a strong association between exposure to electromagnetic fields and mercury level has been found in our previous studies, our findings can lead us to this conclusion that maternal exposure to electromagnetic fields in mothers with dental amalgam fillings may cause elevated levels of mercury and trigger the increase in autism rates. Further studies are needed to have a better understanding of the possible role of the increased mercury level after exposure to electromagnetic fields and the rate of autism spectrum disorders in the offspring.

Main findings

This paper introduces a hypothesis that maternal exposure to electromagnetic fields, particularly MRI and microwave radiation from mobile phones, may increase mercury release from dental amalgam fillings. It proposes that elevated maternal mercury exposure could be a possible mechanism contributing to higher autism rates in offspring, and states that further studies are needed.

Outcomes measured

  • Mercury release from dental amalgam fillings
  • Maternal/cord blood mercury levels
  • Autism spectrum disorders
  • ADHD
  • Neurotransmitter changes/neurological problems

Limitations

  • Hypothesis paper rather than a direct empirical study
  • Does not report original sample size or new experimental data in the abstract
  • Causal link between EMF-related mercury release and autism in offspring is not established
  • Relies on prior studies and indirect associations
