## Abstract

The U.S. Fish and Wildlife Service (Service) amends Section 20.21(j) and temporarily approves tungsten-iron shot as nontoxic for the 1997-98 migratory bird hunting season. The toxicological report and extensive literature search and analysis suggests that tungsten and tungsten-iron are nontoxic under conditions for the proposed shot configuration. Analysis of the toxicity study reveals no adverse effects over a 30-day period when dosing mallards with 8 BB-size tungsten-iron shot.
