Nomination Date: 11/15/1999
Nominator: Private Individual
Rationale: Chlordane, Dursban & Diazinon were renominated for study based on their wide spread use and misapplication. Chlordane, although banned, persists in the environment and in homes that were sprayed with it. More recent applications of Dursban and Diazinon in these same homes has created a complex mixture of poisons. New information regarding the action of endocrine disruptors make this group of poisons appropriate chemicals for study.
