Together with the other "drins", aldrin, dieldrin and endrin, isodrin was developed in the 1940s to provide an alternative to DDT. European drin production peaked in 1967 and ceased in 1990. It used to be commonly used as an insecticide in agriculture and to control malaria spreading mosquito's. Since isodrin is no longer manufactured or used in the European Union or the United States, its leakage to the marine environment from these countries is not expected to be significant. In water mostly adsorbs to suspended particles, organic matter, soils and sediments. It has a low tendency to evaporate and isn't easily degraded in the atmosphere, causing it to be transported over great distances. It is also stable in water and soils. It can take between 0,5 and 6 years to half the isodin concentration of a soil. [1]

Isodrin may bioaccumulate in aquatic organisms and has a tendency to [biomagnification|biomagnify]] through food chains. UK environment agency

Isodrin is a very toxic chemical for fresh water fishes. They die when exposed to concentrations above 6 µg/l. Zooplankton and chrustations start dying when exposed to concentrations above 1 mg/l. www.pesticideinfor.org
