<unk>  is an organochloride with the chemical formula C12H8Cl6O that was first produced in 1950 by Shell and Velsicol Chemical Corporation. It was primarily used as an insecticide, as well as a rodenticide and piscicide. It is a colourless, odorless solid, although commercial samples are often off-white.<unk>  was manufactured as an emulsifiable solution known commercially as Endrex. The compound became infamous as a persistent organic pollutant and for this reason it is banned in many countries. In the environment<unk>  exists as either<unk>  aldehyde or<unk>  ketone and can be found mainly in bottom sediments of bodies of water. Exposure to<unk>  can occur by inhalation, ingestion of substances containing the compound, or skin contact. Upon entering the body, it can be stored in body fats and can act as a neurotoxin on the central nervous system, which can cause convulsions, seizures, or even death. Although<unk>  is not currently classified as a mutagen, nor as a human carcinogen, it is still a toxic chemical in other ways with detrimental effects. Due to these toxic effects, the manufacturers cancelled all use of<unk>  in the United States by 1991. Food import concerns have been raised because some countries may have still been using<unk>  as a pesticide.
