Like heavy metal? Think again.
Like heavy metal? Think again.
We’re not talking Ozzy here, but in fact heavy metals that can be very harmful
to your health if found in your drinking water.
Severe effects include reduced growth and
development, cancer, organ damage, nervous system damage, and in extreme cases,
death.
Exposure to some metals, such as mercury and lead, may also cause development of autoimmunity,
in which a person's immune system attacks its own cells. This can lead to joint
diseases such as rheumatoid arthritis, and
diseases of the kidneys, circulatory system, and nervous system.
The young are more prone to
the toxic effects of heavy metals, as the rapidly developing body systems in
the fetus, infants and young children are far more sensitive.
Childhood exposure to some
metals can result in learning difficulties, memory impairment, damage to the
nervous system, and behavioral problems such as aggressiveness and
hyperactivity.
At higher doses, heavy
metals can cause irreversible brain damage. Children may receive higher doses
of metals from food than adults,
since they consume more food for their body weight than adults.
Where
do they come from?
Toxic metals can be present in industrial, municipal, and urban runoff, which can be harmful to humans and aquatic life.

Increased urbanization and
industrialization are to blame for an increased level of trace metals,
especially heavy metals, in our
waterways.
waterways.
There are over 50 elements
that can be classified as heavy metals, 17 of which are considered to be both
very toxic and relatively accessible.
Toxicity levels depend on
the type of metal, it's biological role, and the type of organisms that are
exposed to it.
The heavy metals linked most often to human poisoning are lead, mercury, arsenic and cadmium.
Other heavy metals, including copper, zinc, and chronium, are actually required by the body in small
amounts, but can also be toxic in larger doses.
Heavy metals in the environment are caused by air
emissions from coal-burning plants, smelters, and other industrial facilities;
waste incinerators; process wastes from mining and industry; and lead in
household plumbing and old house paints.
Industry is not totally to blame, as heavy metals can
sometimes enter the environment through natural processes. For example, in some
parts of the U.S., naturally occurring geologic deposits of arsenic can
dissolve into groundwater, potentially resulting in unsafe levels of this
heavy metal in drinking water supplies in the area.
Once released to the environment, metals can remain for
decades or centuries, increasing the likelihood of human exposure.
In addition to drinking water, we can be exposed to heavy
metals through inhalation of air pollutants, exposure to contaminated soils or
industrial waste, or consumption of contaminated food.
Because of contaminated water, food sources such as
vegetables, grains, fruits, fish and shellfish can also become contaminated by
accumulating metals from the very soil and water it grows from.
What affects the quality of surface and groundwater?
