Tin has no known natural biological role in living organisms. It is not easily absorbed by animals including humans. The low toxicity is relevant to the widespread use of tin in dinnerware and canned food. [1] Nausea, vomiting and diarrhea have been reported after ingesting canned food containing 200 mg/kg of tin.

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 ]
A variety of tin alloys morphologies exist including the following metals: soft solder, fusible, pewter, bronze, Babbit, White, and phosphor bronze metal. [9] Tin oxide metals are corrosive resistant which is important in industrial uses. [9] Tin(II) oxide, or Stannous oxide, is a brown-black powder or blue-black crystalline solid compound.
Metals can be toxic in high quantities. Either ingestion or faulty metabolic pathways can lead to metal toxicity (metal poisoning). Sources of toxic metals include cadmium from tobacco, arsenic from agriculture and mercury from volcanoes and forest fires. Nature, in the form of trees and plants, is able to trap many toxins and can bring ...
Potential sources of heavy metal poisoning include mining, tailings, smelting, industrial waste, agricultural runoff, occupational exposure, paints and treated timber. Physical and chemical characterisations of heavy metals need to be treated with caution, as the metals involved are not always consistently defined.
Tin is a post-transition metal in group 14 of the periodic table of elements. It is obtained chiefly from the mineral cassiterite, which contains stannic oxide, SnO 2. Tin shows a chemical similarity to both of its neighbors in group 14, germanium and lead, and has two main oxidation states, +2 and the slightly more stable
