SUMMARY

Aldrin is an obsolete organochlorine insecticide. It is banned from use in the EU and most of the developed world. It is virtually insoluble in water, quite volatile but unlikely to leach to groundwater. There are field studies that have shiown that aldrin can be persistent in soils. It is highly toxic to mammals and has a high potential for bioaccumulation. Aldrin is considered to be a carcinogen and neurotoxicant. It is highly toxic to most biodiversity.
