Five Common Toxic Metals to Avoid
And Where You'll Find Them
By Dr. Joseph Mercola with Rachael Droege
Are you feeling tired or irritable? Is your head foggy or are you suffering
from Alzheimer's disease, depression or anemia? These are just a
few of the signs that you may be suffering from metal poisoning--a toxic
accumulation of heavy metals in the soft tissues of the body.
Heavy metal poisoning is much more common than most people realize,
and if you're thinking that it doesn't apply to you because
you haven't been exposed to any, think again. If you've eaten
fish regularly, had amalgam fillings, received vaccinations, drank contaminated
water, or done industrial or agricultural work or pharmaceutical manufacturing,
there's a good chance that you have a fair amount of toxic metals
in your system.
The effects of these toxic metals can range from subtle symptoms to
serious diseases. Since metals build up in your body over time, symptoms
are often attributed to other causes and people often don't realize
that they have been affected by metals until it's too late.
The worst part about heavy metals is that once they build up in your
body they can cause irreversible damage. Further damage can be prevented
by removing the metals, but this can be a slow, difficult process. Prevention
is the best defense when it comes to metal poisoning, and this list of
five common toxic metals will give you a heads up to avoiding further
exposure to these health-degenerating elements.
Mercury
Mercury is one of the most problematic of all toxic metals because,
despite its dangers and known role as a neurotoxin, many people have it
implanted in their mouth, injected into their bloodstream, or are consuming
it daily in fish.
Dental Amalgams
If you are one of the millions of Americans who has received silver
dental fillings, take heed: Mercury makes up about 50 percent of every
amalgam dental filling, also known as "silver" fillings. According
to the American Dental Association, "Dental amalgam (silver filling)
is considered a safe, affordable and durable material that has been used
to restore the teeth of more than 100 million Americans. It contains a
mixture of metals such as silver, copper and tin, in addition to mercury,
which chemically binds these components into a hard, stable and safe substance.
Dental amalgam has been studied and reviewed extensively, and has established
a record of safety and effectiveness."
However, consider that while 78 percent of Americans have dental fillings,
95 percent of people with disorders of the central nervous system such
as MS, epilepsy, paralysis and migraines also have silver dental fillings.
This begs the question, would you want mercury, one of the most powerful
neurotoxins on the planet, embedded in your mouth, only inches from your
brain? The answer is obvious.
Vapors from amalgams are released continually, and studies have found
that those with these fillings can have mercury vapor concentration 10
times higher than people without them. Simple activities such as chewing
gum, drinking hot liquids and brushing teeth can increase the release
of mercury even more.
If you decide to have your amalgams replaced with a nontoxic material,
the most important thing is to find a dentist who can remove your amalgams
safely. Any dentist can technically replace your amalgams, but if they
don't employ proper precautions much of the mercury in your fillings
will go straight to your brain. Secondly, I would highly recommend getting
healthy BEFORE you start on your fillings. Even a good dentist will likely
liberate some mercury in the removal process and you want your detoxification
mechanisms optimized prior to removal.
Vaccines
Thimerosal, a mercury-containing vaccine preservative, is still widely
used in vaccines, including those routinely administered to children.
Thimerosal contains close to 50 percent ethyl mercury by weight. Children
are particularly sensitive to the mercury as their nervous systems are
still rapidly developing. Years ago, health-related organizations such
as the American Academy of Pediatrics (AAP) and the Centers for Disease
Control and Prevention (CDC) recommended that thimerosal be removed from
vaccines as soon as possible, yet it's still present in many vaccinations
including Hepatitis B, diphtheria, pertussis, acellular pertussis, tetanus
and Hib.
Over the past decade, the prevalence of autism and other neurodevelopmental
disorders such as attention deficit disorder have been increasing at epidemic
proportions, and many experts believe that mercury from vaccines is at
least partly to blame. It is thought that a child's reduced ability
to excrete the mercury --children's detoxification abilities may
vary greatly-- may also play a role.
It is possible to get childhood vaccines without thimerosal, since some
manufacturers have developed thimerosal-free vaccines, however, you will
have to ask your doctor to check the package insert and provide a written
guarantee that the vaccine is mercury-free. Even then you will not know
for sure, as the package inserts, which are supposed to detail exactly
what is in a vaccine, may not even be accurate. You will also want to
read the many other reasons why vaccines can do more harm than good.
Fish
Tragically, our oceans are largely contaminated with industrial pollutants
like mercury. Ocean and farm-raised fish pick up these toxic chemical
residues, which bioconcentrate in their flesh.
The larger the fish, the more problematic because big fish eat smaller
fish, thereby getting an even greater dose of accumulated toxins. People
who regularly eat fish have higher levels of methylmercury than those
who don't.
Even the conservative Environmental Protection Agency and Food and Drug
Administration have issued warnings about the dangers of mercury in fish,
and they are now planning to issue a federal warning to pregnant and nursing
women, and even those thinking of getting pregnant to limit their consumption
of tuna, along with their previous warnings about other types of fish,
due to mercury concerns. Pregnant and breastfeeding women can transfer
mercury to their newborns, causing significant neurological problems.
Even if you are a man or not planning to become pregnant, mercury from
fish can still accumulate in your body and cause serious problems down
the road. If you do eat fish, please be sure to have it lab tested for
mercury. We have found a brand of salmon, Vital Choice, that has tested
free of mercury time and time again, so this is one option for those of
you looking for a safe source of fish. Alternatively, most sardines have
little to no mercury since they are so small, and you can also take a
high-quality, purified fish oil or cod liver oil to safely receive the
health benefits of fish without the mercury.

Lead
There are many ways that humans can be exposed to lead. Among the major
sources are lead-based paint, leaded gasoline, lead-contaminated water,
manufacturing of lead batteries, rubber products, glass and other lead-containing
products, and lead oxide fumes that result when demolishing industrial
buildings. While some of these sources, such as lead-based paint and leaded
gasoline, have been discontinued over the past few decades, their effects
still show up in the environment. For instance, it is estimated that 64
million homes in the United States still contain lead paint, which can
either be ingested in flakes or inhaled as a microscopic dust.
According to the National Health and Nutrition Examination Survey (NHANES),
the prevalence of lead toxicity (levels greater than 10 mcg/dL) in US
children ranged from 1.5 percent for upper-income white children living
in recently built houses in the suburbs, to 36.7 percent for black children
residing in large cities. Children are more susceptible to lead absorption
than adults, whose lead toxicity is generally related to occupational
exposure. It's estimated that more than 800,000 US workers are exposed
to lead through their work.
However, low-level exposure to lead, such as through drinking water
or living near an incinerator or toxic dump, is also associated with many
negative health effects like brain dysfunction in children, neurobehavioral
changes in adults (such as a reduction in cognitive abilities and IQ,
and personality changes), hypertension and chronic kidney disease.
Aluminum
As with the other elements, aluminum is absorbed and accumulated in
the body, and has been linked to serious illnesses including osteoporosis,
extreme nervousness, anemia, headache, decreased liver and kidney function,
forgetfulness, speech disturbances and memory loss.
Aluminum has also been widely associated with Alzheimer's disease.
People who have died from Alzheimer's disease have been found to
have up to four times the average amount of aluminum accumulated in the
brain's nerve cells.
Antiperspirants
Antiperspirants contain aluminum that is absorbed by your body. It's
best to avoid it all together and use simple soap and water instead. Deodorants
aren't as bad as antiperspirants, but I would also avoid using them
unless it was made from some form of baking soda.
Water
Aluminum-contaminated water is another significant concern, as studies
have found that Alzheimer's disease is more common in regions where
levels of aluminum in drinking water are highest.
To find out whether you may be at risk from aluminum and other toxins
in your water you'll need to have your water tested by a reliable source.

Recommended Water Tests" -- to ensure the safety of your tap water today.
Other Common Sources
- Aluminum cookware: Although aluminum pots are probably less problematic
than the sources mentioned above, I personally would not use aluminum
cookware.
- Aluminum foil
- Over-the-counter drugs: These include many antacids, anti-diarrheal
drugs and drugs used for pain and inflammation.
- Several douche brands
- Some baking powders: Most baking powders contain aluminum as an additive,
but health food stores carry non-aluminum varieties.
- Refined foods, refined flours, baked goods, processed cheeses, and
common table salt
Arsenic
Organic arsenic compounds are mainly used as pesticides, primarily on
cotton plants, while inorganic arsenic is primarily used to preserve wood.
Once arsenic is released in the environment it cannot be destroyed, and
many arsenic compounds dissolve in water.
The primary route of exposure to high levels of arsenic is typically
through occupational hazards, or near hazardous waste sites or areas with
high natural levels. You can also be exposed by breathing sawdust or burning
smoke from arsenic-treated wood. Arsenic has also shown up in drinking
water, especially among well water, and long-term exposure to arsenic
in drinking water has been linked to cancer of the bladder, lungs, skin,
kidney, nasal passages, liver and prostate.
Exposure to low levels of arsenic can cause nausea and vomiting, decreased
production of red and white blood cells, abnormal heart rhythm, damage
to blood vessels, and a sensation of "pins and needles" in hands
and feet, and over the long term can cause darkening of the skin and the
appearance of small "corns" or "warts" on the palms,
soles, and torso.
In January 2001, the EPA revised the standard allowable level of arsenic
in drinking water from 50 parts per billion (ppb) to 10 ppb. Levels must
reach this lower amount by 2006. However, some experts believe that an
even tougher standard of 3 parts per billion should have been adopted.
It's a good idea to have your water tested for arsenic, especially
if your water comes from a well, to ensure you are not being slowly poisoned.
Cadmium
Cadmium, a naturally occurring metal, can be found in food, water and
cigarette smoke. It is a known human carcinogen that appears to act in
two ways: it harms DNA directly and disturbs a DNA repair system that
helps to prevent cancer.
Like other metals, cadmium stays in the body for a long time and accumulates
after long-term exposure to even low levels. Cadmium is released into
the air from mining, industry, burning coal and household wastes, where
it then binds to soil particles and dissolves in water. Fish, plants,
and animals accumulate cadmium from the environment, as such there are
low levels of the metal in most all foods with the highest levels found
in shellfish, liver, and kidney meats.
People are exposed to cadmium not only through foods but also through
drinking contaminated water and breathing cadmium-contaminated air (such
as near burning waste, battery manufacturing, metal soldering or welding).
Cadmium is also present in cigarette smoke, and smoking doubles the average
daily intake.
It is thought that cadmium is carcinogenic, and long-term exposure to
low levels can contribute to kidney disease, lung damage and fragile bones.
Animal studies also suggest that it may lead to liver disease, high blood
pressure, and nerve or brain damage.

Many people are making the decision about whether to receive the flu
shot. Our hopes in providing the following article is to provide you with
facts that will better enable you to make informed decisions. The flu
vaccine, consumed faithfully by the public without question each year,
is not without problems.
The vaccine contains formaldehyde, a known cancer-causing agent. It
also contains the preservative thimerosal, a derivative of mercury, a
known neurotoxin linked to brain damage and autoimmune diseases. Aluminum
is another flu vaccine ingredient and is also a toxic heavy metal that
has been associated with an increased incidence of Alzheimer's Disease.
The influenza epidemic that hit North America so strongly in January
2000 was the worst in 5 years. Of interest is the fact that a large percentage
of the elderly that contracted the flu did so despite having had their
flu shots. One nursing home in Toronto recorded 32 cases of the flu; of
those who became ill, 31 had been vaccinated against the flu the month
before.
Please make an informed decision about this, and have all your questions
answered. Vaccines are drugs and can come with side effects that can impact
your health now and in the future. We have numerous articles available
to you to help you decide what is best for you and your family. Don't
forget - inside of us, we already have everything we need to be truly
healthy and an immune system that is designed to fight infection!
According to Hugh Fudenburg, MD - the world's leading immunogeneticist
and 13th most quoted biologist of our time (nearly 850 papers in peer
review journals) - if an individual has had 5 consecutive flu shots between
1970 - 1980 (the years of the study) his/her chance of developing Alzheimer's
Disease is 10 times greater than if they had 1, two or no shots. When
asked why Dr. Fudenberg stated that it is due to the mercury and aluminum
buildup that is in every flu shot (and in almost all childhood shots).
The gradual mercury and aluminum buildup in the brain causes cognitive
dysfunction. Alzheimer's is now expected to quadruple. Dr. Fudenberg's
comments are from his speech at the NVIC International Vaccine Conference,
Arlington VA September, 1997. Alzheimer's to quadruple statement is
from the John's Hopkins Newsletter of November 1998.
