[QUOTE="shaughn, post: 1245586"] Don't worry about lead, worry about Cadmium and that is a naturally occurring heavy metal contaminant, made worse due to past mining activity (old mine heads,tailing piles etc), which leads to migration of the material, but is in trace elements in soil everywhere. There are plants, that biomagnify the levels of cadmium, willow in particular, which leads to higher concentrations of the Hmetal in the liver and kidneys of birds/deer/elk etc and could lead to reproduction issues . If hunters refrain from eating the organs, then the level of Cadmium exposure is minimal, but if they eat vegetables grown in the soil, then you are back in the same situation. A problem with Cadmium poisoning, is that it leads to leaching of Calcium from the bones, which causes a condition similar to osteoporosis, leading to bone fractures and possible death of said animal. One study I remember dealt with ptarmingan. Then scavengers (hawks, eagles,condors,fox, coyote etc) get at the carcass and eat the cadmium rich organ meat and this results in elevated levels in their own organs. I tend to think the "Lead" issue is being used to further an agenda in certain regions of the country and no matter how much contrary research is submitted, the idea of Hunters and their awful lead bullets, is an easier agenda to push and to get further funding and limit/end an activity that they find objectionable, than admit that Cadmium, which exists naturally and can't be cleaned up, is a major contributor to the decreasing numbers of..(animal of choice).
