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 ...
Metal toxicity or metal poisoning is the toxic effect of certain metals in certain forms and doses on life. Some metals are toxic when they form poisonous soluble compounds. Certain metals have no biological role, i.e. are not essential minerals, or are toxic when in a certain form. [ 1 ]
Some heavy metals are either essential nutrients (typically iron, cobalt, copper and zinc), or relatively harmless (such as ruthenium, silver and indium), but can be toxic in larger amounts or certain forms. Other heavy metals, such as arsenic, cadmium, mercury, and lead, are highly poisonous.
This category reflects the organization of International Statistical Classification of Diseases and Related Health Problems, 10th Revision.

“Organic food doesn’t necessarily mean that it’s been checked for exposure to toxic metals like lead, cadmium and arsenic,” said Manish Arora, vice chairman of the department of ...
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.

Besides the individual toxic effects of each metal, a wide range of metals are nephrotoxic in humans and/or in animals. [29] Some metals and their compounds are carcinogenic to humans. [citation needed] A few metals, such as lead and mercury, can cross the placental barrier and adversely affect fetal development. [30]
