Is Obama administration moving towards a ban on leaded ammunition?
Some other information on a U.S. Centers for Disease Control and Prevention (CDC) study from 2008 is available here. Only a small percentage (5.94 percent) of venison shot with lead ammunition was found to have lead in the meat.
The 0.3 +-g/dl (micrograms per deciliter) difference is small but not "insignificant." There was a statistically significant difference in blood lead level between game-consumers and non game-consumers at P<0.0001 level (statistically highly significant). Granted, the mean difference of 0.3 +-g/dl more lead in the blood of game-consumers than non game-consumers is not large by contemporary levels (although it is orders of magnitude higher than the 0.016 g/dl baseline that the report recommends be the reference point). But, the conclusion from the study is simple: People who eat game are exposed to more lead than people who dont eat game. That's all. The study design could not determine whether that exposure was biologically important because blood lead elevation is short-lived.
