Migratory Bird Hunting; Temporary Approval of Tin Shot as Nontoxic for Hunting Waterfowl and Coots During the 2000-01 Season

Краткое содержание

The U.S. Fish and Wildlife Service (Service or we) proposes to grant temporary approval of tin shot as nontoxic for hunting waterfowl and coots during the 2000-2001 season. Acute toxicity studies reveal no adverse effects over a 30-day period on mallards (Anas platyrhynchos) dosed with tin shot. Reproductive/chronic toxicity testing over a 150- day period indicated that tin administered to adult mallards did not adversely affect them or the offspring they produced. Tin shot is produced by the International Tin Research Institute, Ltd. (ITRI) of Uxbridge, Middlesex, England.
