Chlordecone, better known in the United States under the brand name Kepone, is an organochlorine compound and a colourless solid. It is an obsolete insecticide, now prohibited in the western world, but only after many thousands of tonnes had been produced and used.[3] Chlordecone is a known persistent organic pollutant that was banned globally by the Stockholm Convention on Persistent Organic Pollutants in 2009.[4]
