BACKGROUND.

Libby amphibole asbestos, found in vermiculite ore deposits near Libby, MT, is comprised of mixture of related mineral forms of amphibole asbestos: primarily winchite, richtorite and tremolite with trace amounts of magnesioriebeckite, edenite, and magnesio-arfvedsonite.

EPA's Office of Research and Development has requested the SAB to review EPA’s draft "Toxicological Review of Libby Amphibole Asbestos In Support of Summary Information on the Integrated Risk Information System (IRIS)." The draft assessment evaluates cancer and noncancer health hazards and exposure-response of Libby amphibole asbestos.
