Abstract
Mercury
toxicity and intoxication (poisoning) are realities that every American needs to face. Both the Environmental Protection Agency
and National Academy of Science state that between 8 to 10% of American women have mercury levels that would render any child
they gave birth to neurological disorders. One of six children in the USA have a neurodevelopmental disorder according to
the Centers for Disease Control and Prevention. Yet our dentistry and medicine continue to expose all patients to mercury.
This article discusses the obvious sources of mercury exposures that can be easily prevented. It also points out that genetic
susceptibility and exposures to other materials that synergistically enhance mercury and ethyl-mercury toxicity need to be
evaluated, and that by their existence prevent the actual determination of a "safe level" of mercury exposure for
all. The mercury sources we consider are from dentistry and from drugs, mainly vaccines, that, in today's world are not only
unnecessary sources, but also sources that are being increasingly recognized as being significantly deleterious to the health
of many.
Dental amalgam constitutes the greatest source of mercury for the general population - up to six
times more than all other sources combined. - WHO 1991 Criteria 118
The No Observable Effects Level (NOEL) for Mercury is ZERO
80% of inhaled mercury vapour is absorbed through
the lungs and distributed throughout the body
Mercury from amalgam is absorbed into the body at a rate of 1 - 27
mcg per day
Mercury is the third most toxic substance known to man after lead and arsenic
Mercury constitutes
about 50% of amalgam fillings
Mercury is released continuously form set amalgam for the life of the filling
Mercury causes single strand breaks in DNA
Mercury is Mutagenic
Mercury causes a reduction in
immune function
Mercury can bind to proteins in the body and begin a chain of autoimmune disease
Mercury
from amalgam crosses the placenta and breast milk
Mercury enters the fetus and new born child from the mother's
amalgam fillings
Mercury levels in the fetus are directly related to the number of amalgam fillings in the mother's
mouth
Mercury from amalgam causes a reduction in Kidney filtration function
Mercury from amalgam can
cause kidney disease and other kidney dysfunction
Mercury from amalgam can have a devastating effect on cardiac
function
Mercury from amalgam can spread to every cell in the body
Mercury from amalgam concentrates
in the Central Nervous System
The brain accumulates about 10 times more mercury after exposure to mercury vapour,
compared to equal amounts of mercuric ions being injected or ingested
Mercury can bypass the blood brain
barrier and enter motor neurons
Mercury from amalgam has been directly related to many neurologic disease including
motor neurone disease and glioblastomas
Mercury has been definitively shown to cause neurofibrilar tangles
in nerve tissue
which is identical to Alzheimer's disease.
Lead, cadmium and Aluminium did not have
this effect.
Mercury is transported along nerve fibres at a rate of about 10mm per day
Mercury is also
absorbed into the peripheral nerves
Mercury causes deficits in both cognitive and motor function tasks
Small amounts of Mercury from amalgam can cause changes in the brain that are identical to those
observed in Alzheimer's
Disease Patients
Mercury is bound to haemoglobin in the red blood cells and blocks oxygen carrying capacity of
the blood
Mercury causes changes in the numbers of white blood cells
Mercury is related to increased
blood cholesterol levels
Mercury interferes with female and male reproduction
Mercury can cause infertility,
miscarriage and still birth
Mercury in utero causes learning deficits in children
Mercury is converted
to Methylmercury in the human body -
this is the form of mercury we are warned about when eating fish
Mercury
causes photophobia - bright light sensitivity
Mercury causes Acrodynia - Pink Disease
Mercury toxicity
increases substantially when combined with other metals such as lead or Cadmium
Mercury has been associated with
a range of respiratory problems including asthma
Mercury poisoning is associated with development of Autism
Mercury damages blood vessel walls
Mercury is strongly related to heart attacks
Mercury from
amalgam causes an increase in antibiotic-resistant bacteria in the human gut
Mercury causes a change in the normal
bacterial inhabitants in the gut
Micro-mercurialism means poisoning form long term, low level mercury exposure
- precisely the type of exposure to mercury that amalgam fillings provide. Early symptoms are usually sub-clinical
(meaning that you would normally not yet show symptoms that you would consult a doctor about) and neurological (affecting
the nervous system). These early symptoms include;
Fatigue - physical and mental
Lack
of initiative
Loss of short term memory
Lack of concentration
Poor to no decision making ability
Irrational
obsession Compulsions
Timidity & lack of self confidence
Grave depression
Rapid mood changes,
Sudden
anger
Unexplainable fear of death
Hallucinations
Shyness and timidity
Tendency to isolation
Suicidal
Dental Amalgam is treated as Toxic Waste everywhere, except in a living human mouth.
