"I wish I had had my amalgam fillings removed earlier. I can't wait to regain my health again. I urge whoever is having a health issue to look at the status of their teeth. My sister has no amalgam fillings and she's in much better health than me. I am convinced that mercury toxicity is killing me slowly!"
Juli Saffron, Chronic illness sufferer

Mercury Toxicity Questionnaire

A great deal of the degeneration and illness that we see around us is not the result of the inevitable and 'normal' process of ageing, but the consequence of exposure to an unprecedented level of toxins combined with a marked deterioration in the nutritional content of our diets. 

Of all the toxins to which we are exposed, mercury is one of the most harmful and the one to which many of us have the greatest exposure. It is a multipotent toxin which causes damage on many different levels in biological systems.

Mankind - especially in the West - has now been exposed to many centuries of the 'therapeutic' use of mercury in medicine and dentistry, Significantly, this body burden accumulates over time and this unwelcome and invisible legacy is passed down the generations from mother to child. 


Sources of mercury

The main sources of mercury to which we are exposed include:

  • Dental amalgam fillings which are a mixture of approximately 50% liquid mercury combined with other powdered metals. When these metals are mixed together in the moisture of the mouth they form a battery which causes the liquid mercury to vaporise as it discharges its current. This source has been assessed by the World Health Organisation (WHO) to be the biggest source of mercury for most people representing approximately 65-90% on average of most people's exposure. This has been a significant source of mercury exposure for approximately seven generations. In addition, the formula was changed in favour of high copper (non-gamma II) amalgam in the 1970s which has been shown to release 50X the mercury of the previous formulation, so that for the last 40 years this source has been massively amplified.
  • The vaccination programme The introduction of the vaccination programme including many vaccinations containing the mercury-based preservative, thimerasol, has ramped up from a few vaccinations in childhood given to those in their fifties and sixties to the many dozens of vaccines recommended or mandated over an entire lifetime now. 
  • Fish Inorganic mercury pollution mainly from industry contaminates the waterways and is then converted to the more toxic organic mercury by plankton. This form then bioconcentrates up the food chain to appear in significant quantities in the larger carnivorous fish such as tuna and swordfish.
  • Occupational mercury exposure This has historically been an issue for people involved in the mining or refining of mercury, and hat makers (mercury was used to treat the pelts used for top hats, etc). It is still an issue for people working in particular industries and laboratories, healthcare workers (from accidental spills), and dentists and their chairside assistants from exposure to the mercury vapour emitted when removing and placing amalgam fillings.
  • The use of mercury in medicines Historically, this has been a significant source of exposure as physicians have used mercury-containing medicines for centuries as purgatives and disinfectants, and to treat syphilis, yellow fever, and teething. Some pharmaceuticals and other chemicals used in medical applications still contain mercury. And, Calomel, which was used for teething was only finally withdrawn from sale 60 years ago. 
  • Energy saving light bulbs The energy saving (but not environmentally friendly) mercury containing light bulbs contain significant amounts of mercury if broken and this will inevitably end up in landfill and also poses a threat to householders. 
  • Alchemical and chemical use For many centuries, alchemists were fond of trying to transform mercury into gold in a number of ways. Mercury is only one atomic weight heavier than gold and became the target of much experimentation.
  • Accidental exposure Mercury vapour is odourless, tasteless and invisible and so people may have no idea that they have been so exposed. 
  • Intentional poisoning Mercury poisoning has proved a popular way of disposing of enemies for centuries because there is an asymptomatic period of 'silent latency' of at least several months and then the symptoms are mostly not recognised for what they are. This means that both the culprit and the crime have largely gone undetected until recently. Mercury poisoning is also hard to reverse once exposure has occurred. 
  • Mercury-containing products This category includes a wide range of products ranging from floor waxes and latex paints to fabric conditioners, and contact lens solutions.
  • Atmospheric pollution Although volcanoes produce some atmospheric mercury naturally, coal-fired power stations now represent the biggest source of mercury in the atmosphere. 
  • Generational Significantly, mercury is passed from mother to child both in the womb and in the breast milk. Between one-third and two-thirds of the mother's total accumulated mercury burden passes to her offspring in this way, so that the mother is effectively detoxifying into her offspring. These means that over the generations the total mercury burden has steadily increased and some individuals have started life with a significant body burden that has predisposed them to ill health and neurological problems from childhood onwards. 


Each of these sources combine to create an individual's body burden of mercury. The body has great difficulty excreting the sort of quantities of mercury that it is typically exposed to through these sources and both the kidney and liver accumulate and are damaged by mercury. This means that the two main routes out of the body rapidly become ineffective.

The amount of mercury toxicity in the population at large goes largely underdiagnosed because it can take so many forms. In my opinion metal toxicity in general and mercury toxicity in particular are massively overlooked as sources of chronic, serious and degenerative illness. 


Assessing the symptoms of mercury toxicity

The questionnaire below is taken from The Natural Recovery Plan book by Alison Adams and solicits answers to some (but not all) of the recognised signs and symptoms of mercury poisoning. The results of the questionnaire can give a broad indication of the degree of mercury toxicity within the cells, since this frequently does not show up in blood, urine, hair or nail analysis as the mercury is bound to the cell organelles (where it can cause disruption but not be detectable) and to the nervous tissue of the peripheral and central nervous systems.

Mercury toxicity questionnaire: Article summary

This questionnaire is taken from The Natural Recovery Plan book and poses a comprehensive list of questions covering many common manifestations of mercury toxicity. The outcome gives an indication of the likelihood of mercury toxicity being a health issue since this assesses the degree to which cellular function has been affected by the presence of intracellular mercury rather than measuring the amount of mercury in samples of tissue (blood, urine, hair, etc) which has been shown to be unreliable.
