Toxic metals sometimes imitate the action of an essential element, interfering with the metabolic processes resulting in illness. Many metals, particularly heavy metals are toxic, but some are essential, and some, such as bismuth, have a low toxicity. Metals in an oxidation state abnormal to the body may also become toxic: chromium(III) is an ...
A toxic heavy metal is a common but misleading term for a metal-like element noted for its potential toxicity. [4] Not all heavy metals are toxic and some toxic metals are not heavy. [ 5 ] Elements often discussed as toxic include cadmium , mercury and lead , [ 6 ] all of which appear in the World Health Organization 's list of 10 chemicals of ...
[6] [7] [8] The most widely used toxicology textbook, Casarett and Doull’s toxicology [9] uses "toxic metal" not "heavy metals". [5] Nevertheless, there are scientific and science related articles which continue to use "heavy metal" as a term for toxic substances [ 10 ] [ 11 ] To be an acceptable term in scientific papers, a strict definition ...
But a new study by researchers at USC has found that a popular variety is laden with toxic metals, and estimates retardant use has released 850,000 pounds of these chemicals into the environment ...
Researchers agree that avoiding heavy metals entirely in our diet is nearly impossible. Foods such as rice, fish, fruits and vegetables have been known to contain varying amounts of metals.
This category reflects the organization of International Statistical Classification of Diseases and Related Health Problems, 10th Revision. Generally, diseases outlined within the ICD-10 codes T56 within Chapter XIX: Injury, poisoning and certain other consequences of external causes should be included in this category.
A number of heavy metals, such as cadmium and lead, are toxic to various forms of life, particularly when dissolved in water as metal ions. [1] Toxic heavy metals are often present in surface water as a result of natural processes, such as the weathering of metal-containing rocks, or due to human activity, such as mining and smelting.

By contrast, a toxin is a poison produced naturally by an organism (e.g. plant, animal, insect). [2] The 2011 book A Textbook of Modern Toxicology states, "A toxin is a toxicant that is produced by a living organism and is not used as a synonym for toxicant—all toxins are toxicants, but not all toxicants are toxins.
