Below is an Associated Press story about lead in ammunition. Note that no scientist is going on record in this article and the there is no evidence presented. Just could be or maybe.
Since the Jackson area is part of the Yellowstone caldera there are large amounts of heavy metals and minerals found in the area. Isn’t it more likely that the lead found in the blood of animals in the area comes from their diet. What happened to you are what you eat? The predators and scavengers of the area feed on the animals of the area and drink the same water. Why would they not have heavier levels of lead in their blood.
Being higher on the food chain mean predators and scavengers food sources have already concentrated environmental metals and contaminates in their tissue. So it is easy to see why such predator and scavengers have more lead in their blood. I hate junk science, and worst of all, tax payers probably paid for these “scientists” to be out there pushing their personal agendas.
JACKSON, Wyo. (AP) — Researchers say the distribution of nonlead ammunition to hunters in Jackson Hole is likely helping prevent lead poisoning of ravens, eagles and other scavengers.
This is the second year researchers have tried to gauge the impacts of hunters using lead-free ammunition on the levels of lead found in the blood of big-game scavengers.
Researchers distributed nonlead ammunition to some 100 hunters who had 2010 permits for the National Elk Refuge and Grand Teton National Park.
Biologists then captured ravens and eagles and measured the level of lead in the birds.
Previous research has shown that lead in ravens and eagles rise during hunting season and then drop off after hunting season ends.
The Jackson Hole News and Guide says researchers plan to hand out more lead-free ammunition next hunting season.
