Examining the Link Between Lead Exposure and Poor Health
In the Santa Fe province of Argentina, an international hot spot for duck hunting, more than 10 tons of lead gunshot are introduced into the environment every year. initial studies show that large numbers of native ducks ingest and are poisoned by these lead pellets. Lead contamination may also threaten the health of other species, including humans, who ingest lead that enters the food chain. This study will further quantify the relationship between lead exposure and the health of native ducks and will measure the extent to which humans and animals are exposed to lead in the ecosystem. These data are needed to justify banning the use of lead ammunition in Argentina.
