IPEN Body Burden Community Monitoring Handbook PesticidesDIELDRIN Chemical Name: 1,2,3,4,10,10-Hexachloro-6,7-epoxy-1,4,4a,5,6,7,8,8a-octahydroexo-1,4-endo-5,8- dimethanonaphthalene (C12H8Cl6O). CAS Number: 60-57-1 Properties: Solubility in water: 140 µg/L at 20°C; vapour pressure: 1.78 x 10 -7 mm Hg at 20°C; log KOW: 3.69-6.2. Discovery/Uses: It appeared in 1948 after World War II and used mainly for the control of soil insects such as corn rootworms, wireworms and cutworms. Persistence/Fate: It is highly persistent in soils, with a half-life of 3-4 years in temperate climates, and bioconcentrates in organisms. Toxicity: The acute toxicity for fish is high (LC50 between 1.1 and 41 mg/L) and moderate for mammals (LD50 in mouse and rat ranging from 40 to 70 mg/kg body weight). Aldrin and dieldrin mainly affect the central nervous system but there is no direct evidence that they cause cancer in humans. The maximum residue limits in food recommended by FAO/WHO varies from 0.006 mg/kg milk fat and 0.2 mg/kg poultry fat. Water quality criteria between 0.1 to 18 µg/L have been published.
