Chemical name: 2,7:3,6-Dimethanonaphth[2,3-b]oxirene, 3,4,5,6,9,9-hexachloro-1a,2,2a,3,6,6a,7,7a-octahydro-, (1a.alpha.,2.beta.,2a.alpha.,3.beta.,6.beta.,6a.alpha.,7 Final regulatory action has been taken for the category: Pesticide Final regulatory action: The chemical is Banned Use or uses prohibited by the final regulatory action: All uses as plant protection products are prohibited. Pesticide use or uses that remain allowed: No uses that remain allowed. The final regulatory action was based on a risk or hazard evaluation: Yes Summary of the final regulatory action: Dieldrin was excluded from the list of active substances authorized for use in plant protection products in 1969 under the Law on protection of plants against pests and blights.

High toxicity on humans, residues were detected in water and soil, and human tissues. Persistent and bioaccumulative. Reduction of exposure was required. Expected effect of the final regulatory action in relation to human health: Decrease of chemical risk on humans. Lower residue in crops, more healthy food. Summary of known hazards and risks to the environment: High toxicity to many animals, persistence in the environment, especially in temperate areas, and bioaccumulative in the food chain Dieldrin is highly toxic to fish, crustaceans, and many bird and animal species. Oral doses of dieldrin have caused liver cancer in mice, but not rats.
