What then are the effects of chronic Mercury poisoning?


The effects of chronic mercury poisoning are numerous and differ significantly from person to person. It masquerades as chronic ill-health in the form of Chronic Fatigue Syndrome or it may present as a lupus (SLE / DLE) - like illness, hypothroidism or adrenal dysfunction, or with end-stage renal failure or dementia. That's one of the reasons why, unless health-care professionals have a high index of suspicion, the diagnosis can be easily missed with potentially fatal consequences.


An extensive overview of this subject has been undertaken by Dr Joachim Mutter. [Mutter J. (2011) Is dental amalgam safe for humans? The opinion of the Scientific Committee of the European Commission. Journal of Occupational Medicine and Toxicology, 6(2): 1-17] This article cites 295 separate references, and is one of the most comprehensive scientific papers published in recent years.


Broadly speaking, mercury acts in two main ways to alter cellular functioning:

(1) It reacts with sulfhydryl groups (-SH) impairing the activity of enzymes.

(2) It generates protein adducts that alter both the structure & biological functioning of cellular tissues. Disturbances of immune function are thought to arise in this manner.


Mercury primarily accumulates in kidney, pituitary & central nervous tissue, where it alters brain, endocrine (hormonal) & renal functions. The disruption of enzyme activity throughout the body means that the machinery needed to change one fundamental chemical into another is impaired, with the result that essential systems simply do not work properly and chronic illness ensues.







In a 2003 report commissioned by the Swedish Government, Prof. Maths Berlin, Professor Emeritus of Environmental Medicine, Medical Faculty of Lund, Sweden, stated: “For medical reasons, amalgam should be eliminated in dental care as soon as possible. This will confer gains in three respects. The prevalence of side effects from patients’ mercury exposure will decline; occupational exposure to mercury can cease in dental care; and one of our largest sources of mercury in the environment can be eliminated.”
