Endrin is an insecticide that was commonplace among cotton growers and for the treament of cereals. It was also used to kill rodents. It is a neurotoxin. It is a stereoisomer of Dieldrin. In the soil, it can take up to twelve years to decay. It is one of the twelve substances listed in the Stockholm Convention on Persistent Organic Pollutants, and its production, trade and use is banned since 2004.
