Heavy Metals:

Any metal with a specific gravity of 5.0 or greater, especially one that is toxic to organisms, such as lead, mercury, copper, and cadmium

The term has particular application to cadmium, mercury, lead and arsenic, all of which appear in the World Health Organisation’s list of 10 chemicals of major public concern.Other examples include chromium, cobalt, nickel, copper, zinc, selenium, silver, antimony and thallium.

Toxic heavy metals are found naturally in the earth, and become concentrated as a result of human caused activities. They enter plant, animal and human tissues via inhalation, diet and manual handling, and can bind to, and interfere with the functioning of vital cellular components.
