Hunting, Lead, Wildlife, and Human Health:
A storied past and uncertain future

The human and ecological effects of lead have been studied ad nauseum. Regulators have enacted laws and policies to reduce human exposure to lead and environmental contamination through the ban of use in gasoline, paint, and other products. Spend hunting ammunition is a well-known anthropogenic source of lead in the environment. Widespread mortality of waterfowl associated with ingestion of lead pellets from spent ammunition was the impetus for the 1990s ban of lead and other toxic shot type us in waterfowl hunting. However, in most North American States and Provinces, the use of lead shot and ammunition is still permitted for other forms of hunting (e.g., upland game birds, big game, and varmints). Recent studies on the fate of spent shot have identified potential issues not only for wildlife exposed to the spent ammunition from these other hunting activities, but also the potential implications of human consumption of wild animals harvested using lead ammunition. In this seminar, I’ll discuss the history and current state of lead ammunition use, alternatives, what led to a 2012 law suit against the US EPA and some of the broader implications of this issue.
