METAL TOXICITY AND
OUR TOXIC ENVIRONMENT
We live in a very toxic world; we are
constantly exposed to more chemical toxins than at any
other time in human history.
* The air we breathe is polluted with thousands of chemicals
and heavy metals from industry and exhaust fumes.
* The food we eat has been exposed to chemical fertilisers,
pesticides, radiation, additives, improvers, preservatives,
* The water we drink is either polluted or adulterated.
* Cooking utensils, such as aluminium pots and Teflon
coated pans and plastic microwave dishes, all add toxins
to our food.
* Household cleaners, laid carpets, paints, glues and
solvents release many hidden pollutants.
* Body products often contain harmful chemicals, which
accumulate in the body.
* Our work environment is filled with electro-magnetic
radiation from cellphones, computers and other electronic
* Our minds are polluted with negative thoughts and emotions,
which have an impact on our health and those around us.
* In addition to all this, some choose to smoke tobacco,
inhaling many more chemicals.
SOURCES OF TOXIC METALS
The largest sources of toxic metals come
 Industrial, exhaust and tobacco fumes contain cadmium,
arsenic, lead, tin, beryllium and polonium. Lead, silver
and uranium are present in the air everywhere.
 Dental fillings may contain mercury, platinum and
 Drinking water may contain aluminium, arsenic, cadmium,
lead, nickel, silver and uranium.
 Foods are contaminated in several ways:
* Food additives may contain aluminium and tin.
* Fertilisers contain aluminium, cadmium, polonium and
* Fungicides and pesticides contain mercury and tin.
* Tea, cocoa and coffee may contain high levels of cadmium
* Large fish such as tuna often have high levels of mercury.
* Cooking utensils made of aluminium should be avoided,
because of the aluminium which leaches into the food.
* Canned foods often contain aluminium, antimony and tin.
 Medicines such as antacids and anti-diarrhoeals contain
aluminium; chemotherapeutic medicines may contain platinum.
 Cosmetics, paints, ceramics, batteries, electronic
equipment and plastics all contain varying levels of toxic
EFFECTS OF TOXIC METALS
The effects on the human body are wide
ranging. The most serious effect is that of directly or
indirectly causing cancers. Toxic metals are carcinogenic
in several ways:
- damage to DNA or genes
- depletion of protective anti-oxidants
- suppression of the immune system
- activation of oestrogen receptors.
Many metals, such as aluminium and mercury,
severely attack the nerves and brain causing seizures,
dementia, hyperactivity in kids and Alzheimer’s
disease in the aged.
Any other organ system can be susceptible, especially
the gastro-intestinal tract, kidneys, liver and bone marrow.
Toxicity may not be apparent for many years until debilitating
nerve disorders become apparent, at which stage it may
be too late.
Toxic build-up may be the reason for unexplained symptoms
* lack of energy, vertigo, headaches, numbness, pins and
needles, muscle weakness, neuralgia.
* behavioural changes, hyperactivity, learning disability,
depression, insomnia, irritability.
* hypertension, anaemia.
* abdominal pains, loss of weight.
* allergies, asthma, skin problems.
* overall immune system weakness.
WHAT IS CHELATION?
The word “chelation” is derived
from the Greek word chele which means “claw”
[like that of a crab]. When a chelating agent comes into
contact with certain positively charged metals, it surrounds
and binds to them forming a complex which can then be
transported safely. Examples of chelating agents in nature
are haemoglobin, which chelates an iron molecule in blood,
chlorophyll which chelates a magnesium molecule in plants
and vitamin C which chelates an iron molecule to facilitate
its absorption from the gut. Chelation is the process
whereby certain chelating agents are administered over
a period of time, to draw toxic metals out of the body
to restore health.
EDTA is a synthetic amino acid, which
has been used since the 1940’s for chelating heavy
metals, and is still widely used today in chelation treatments.
Some agents such as EDTA, DMPS and DTPA are given intravenously,
while others such as DMSA and Chorella are given orally.
WHO NEEDS CHELATION?
Almost invariably, everyone has toxins
in their bodies. In order to ascertain whether the toxin
load is high and whether this may be having an impact
on one’s health, one needs to undergo testing. Hair
analysis is easy to perform, but does not always give
an accurate result. A urine challenge test is the most
accurate way of testing for toxic metals. The chelating
agent is administered [usually intravenously] and urine
is collected for several hours. This is then analysed
by the laboratory to determine which metals may be problematic.
HOW IS IT ADMINISTERED?
A comprehensive history is taken and
a full physical examination is performed. A series of
blood tests are required to assess the functioning of
the kidneys, liver and pancreas, and the level of minerals
and lipids in the blood. Cardiovascular and respiratory
fitness testing is also done. Different chelating agents
work best on different metals, so a protocol needs to
be worked out depending on the results of the testing.
Some chelating agents such as DMSA and
Chorella, can be administered by mouth over a prolonged
period of time. More often chelating agents are used in
combinations to get the maximum effect. These are usually
given by intravenous injections once or twice a week for
a course of 25 treatments before retesting is performed.
One may need several courses of treatment extending over
years. EDTA is given by slow infusion, mixed with vitamins
and minerals, over 3 hours, whereas some of the others
can be administered more quickly. Adherence to a healthy
diet, avoidance of smoking and exercise are mandatory
as is the supplementation of multivitamins, anti-oxidants
WHAT ARE THE BENEFITS?
Chelation therapy halts the bad effects
of heavy metal toxicity on the organs and systems of the
body, thereby removing obstructions to the restoration
of health. This stimulates the body’s healing process,
activating enzyme pathways and other metabolic reactions,
and often damage can be reversed. One may start to feel
more alert, with improved concentration and memory, less
depressed and more energised.
Chelation therapy with EDTA is widely
used in the USA and Europe for the treatment of cardiovascular
disorders. EDTA improves function and exercise tolerance
in conditions associated with atherosclerosis, such as
angina, peripheral vascular disease and cerebrovascular
disease. By chelating and removing calcium, along with
a variety of other metals, it has a direct effect on reducing
platelet aggregation, which prevents clotting of the blood
which may otherwise have had fatal consequences. It stimulates
the functioning of the heart, and by stimulating the parathyroid
glands it dilates the coronary arteries. The stimulation
of the parathyroids also has a positive effect on building
bone. EDTA stimulates enzyme activity and improves the
ratio of HDL [good] to LDL [bad] cholesterol.
Thus for anyone with one or more risk
factors for cardiovascular disease, EDTA has been shown
to reduce these risks greatly while improving overall
EDTA also has a positive effect on the
aging process and many other conditions such as Diabetes
Mellitus, Rheumatoid arthritis, Multiple Sclerosis, fibromyalgia,
peripheral neuropathy, osteoporosis, Alzheimer’s
disease, thyroid disorders, porphyria and auto-immune
Hundreds of thousands of chelation treatments
have been performed with few side effects and no deaths.
If practised according to established protocols chelation
therapy is very safe:
 Critics claim that EDTA is dangerous to the kidneys,
but if given slowly and in the correct quantity, it does
not harm the kidneys and in fact will improve kidney function
 If given too quickly, calcium levels may drop too
far causing cramps, but this can be rectified easily.
 Blood sugar levels may also drop, especially in diabetics,
but this is carefully monitored during treatment.
 Blood pressure is also monitored during treatment
as it may drop causing dizziness. This could be caused
by the needle becoming dislodged from the vein.
 Fatigue in the early stages may be due to mineral
or vitamin deficiencies, which can be corrected.
 EDTA may be combined with most cardiovascular medication
without the risk of serious interaction.
Although it may seem expensive at first,
a course of 25 treatments costs a fraction of the cost
of bypass surgery, and the benefits are life-long.
WHY IS IT NOT MORE WIDELY USED?
Chelation therapy is approved in the
USA only for very limited usage; lead toxicity, treatment
of hypercalcaemia, and digitalis toxicity. Over the years
there has been enormous opposition to the use of EDTA
for cardiovascular disease. Cardiologists, cardiovascular
surgeons and pharmaceutical manufacturers are threatened
by the use of a substance, which is effective, relatively
cheap and safe. Bypass surgery benefits surgeons and hospitals
alike. Pharmaceutical drugs needed by sufferers over many
years produce enormous profits. In spite of the cries
of “unscientific” and “unproven”
by the orthodox medical community, there are many studies
highlighting the effective use of EDTA. The thousands
of patients worldwide who have benefited from chelation
support the evidence that it is safe, effective and beneficial.
