Tin is a metal which can combine with other chemicals to form compounds. When tin is combined with chemicals such as chlorine, sulfur, or oxygen, it is called an inorganic tin compound. Inorganic tin compounds are found in small amounts in the earth's crust. They are present in toothpaste, perfumes, soaps, coloring agents, and dyes. Tin can also combine with carbon-containing materials to form organotin compounds. These compounds are used in making plastics, food packages, plastic pipes, pesticides, paints, wood preservatives, and rodent(rats and mice) repellents. There can be tin metal, as well as inorganic and organic tin compounds in the air, water, and soil near places where they are naturally present in the rocks, mined, manufactured, or used.  3, fiche 3, Anglais, - inorganic%20tin%20compound
