Tin medal affected by tin pest. Tin pest is an autocatalytic, allotropic transformation of the element tin, which causes deterioration of tin objects at low temperatures. Tin pest has also been called tin disease, [1] tin blight, tin plague, [2] or tin leprosy. [3] It is an autocatalytic process, accelerating once it begins.
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.

In computer disk drives they can break off and cause head crashes or bearing failures. [9] Tin whiskers often cause failures in relays and have been found upon examination of failed relays in nuclear power facilities. [10] Pacemakers have been recalled due to tin whiskers. [11]
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
A few tin foil hat conspiracy theorists accuse their supermarket poultry of being lab-grown or fake. But this stringy defect is very real and it has an official name: spaghetti meat.
The oxides, in turn, are smelted into the metal. Carbon monoxide was (and is) the reducing agent of choice for smelting. It is easily produced during the heating process, and as a gas comes into intimate contact with the ore. In the Old World, humans learned to smelt metals in prehistoric times, more than 8000 years ago. The discovery and use ...

Stannosis is an occupational, non-fibrotic pneumoconiosis caused by chronic exposure and inhalation of tin. [1] Pneumoconiosis is essentially when inorganic dust is found on the lung tissue; in this case, caused by tin oxide minerals. [2]
