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 essential trace element, but chromium(VI) is a carcinogen. Only soluble metal-containing compounds are toxic.
The earliest known metals—common metals such as iron, copper, and tin, and precious metals such as silver, gold, and platinum—are heavy metals. From 1809 onward, light metals , such as magnesium , aluminium , and titanium , were discovered, as well as less well-known heavy metals including gallium , thallium , and hafnium .
In nuclear science, nuclei of heavy metals such as chromium, iron, or zinc are sometimes fired at other heavy metal targets to produce superheavy elements; [173] heavy metals are also employed as spallation targets for the production of neutrons [174] or isotopes of non-primordial elements such as astatine (using lead, bismuth, thorium, or ...
Iron: iron toxicity, iron poisoning, or iron overload is well known. Iron does test only very weakly positive for the Ames test for cancer, however, since it is such a strong catalyst and essential for the production of ATP and consequently DNA production, any excess soluble iron is toxic especially over time. Too much iron deposited in tissues ...
The relationship between heavy metals and heart health The team analyzed data from 6,418 adults who were between ages 45 and 84 and had participated in the Multi-Ethnic Study of Atherosclerosis .
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 ...

Food researchers often use the 1986 regulations, known as Prop 65, as a safety standard because the Food and Drug Administration doesn’t set limits on heavy metals in most foods, said Leigh ...
