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.

The idea was taken from commercial food storage practices, as they are often dealing with the same pests. [ 15 ] [ 17 ] Pseudoscorpions such as Chelifer cancroides may live in books and feed on book-eating insects, controlling their numbers.
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
However, a number of problems have plagued the study of ancient tin such as the limited archaeological remains of placer mining, the destruction of ancient mines by modern mining operations, and the poor preservation of pure tin objects due to tin disease or tin pest. These problems are compounded by the difficulty in provenancing tin objects ...
The term "white tin" was historically associated with tin mining in Devon and Cornwall where it was smelted from black tin in blowing houses. White tin may also refer specifically to β-tin , the metallic allotrope of the pure element, as opposed to the nonmetallic allotrope α-tin (also known as gray tin), which occurs at temperatures below 13 ...
An agricultural aircraft applies low-insecticide bait against western corn rootworm.. Pest control is the regulation or management of a species defined as a pest; such as any animal, plant or fungus that impacts adversely on human activities or environment. [1]
A study showed that 99.5% of the controlled food cans contain tin in an amount below that level. [4] However, un-lacquered tin cans with food of a low pH, such as fruits and pickled vegetables, can contain elevated concentrations of tin. [2] The toxic effects of tin compounds are based on its interference with iron and copper metabolism.
