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.
Nausea, vomiting and diarrhea have been reported after ingesting canned food containing 200 mg/kg of tin. [2] This observation led, for example, the Food Standards Agency in the UK to propose upper limits of 200 mg/kg. [3] A study showed that 99.5% of the controlled food cans contain tin in an amount below that level. [4]
The river water was contaminated with toxic metals including arsenic, copper, barium, cadmium, chromium, lead, mercury, nickel, and thallium. [2] Cleanup costs may exceed $1.2 billion. [3] A toxic heavy metal is a common but misleading term for a metal-like element noted for its potential toxicity. [4]
Heavy metals are often assumed to be highly toxic or damaging to the environment. [53] Some are, while certain others are toxic only if taken in excess or encountered in certain forms. Inhalation of certain metals, either as fine dust or most commonly as fumes, can also result in a condition called metal fume fever .
After ingestion, toxic features usually develop within a few minutes. The major lethal consequence of aluminium phosphide ingestion is profound circulatory collapse, and is reportedly secondary to these toxins generated, which lead due to direct effects on cardiomyocytes, [3] fluid loss, and adrenal gland damage.

The Environmental Protection Agency on Tuesday proposed the first federal limits on harmful “forever chemicals” in drinking water, a long-awaited protection the agency said will save thousands ...
The oxide layer on aluminium is also destroyed by contact with mercury due to amalgamation or with salts of some electropositive metals. [39] As such, the strongest aluminium alloys are less corrosion-resistant due to galvanic reactions with alloyed copper , [ 32 ] and aluminium's corrosion resistance is greatly reduced by aqueous salts ...
People are ingesting borax. Also known by its chemical name sodium borate decahydrate, borax is a salt typically used to kill ants and boost laundry detergent, among other household cleaning needs ...
