Migratory Bird Hunting; Approval of Tungsten-Nickel-Iron Shot as Nontoxic for Hunting Waterfowl and Coots

摘要

We propose to approve shot formulated of tungsten, nickel, and iron as nontoxic for hunting waterfowl and coots. We assessed possible effects of the tungsten-nickel-iron (t-n-i) shot, and have made a preliminary determination that it is not a significant threat to wildlife or their habitats and that further testing of t-n-i shot is not necessary. In addition, approval of t-n-i shot may induce more waterfowl hunters to switch away from lead shot, reducing lead risks to species and habitats.
