Lead tastes sort of sweet, so the Romans sprinkled it as a sweetener on their food. Of course history records them having problems with lead poisoning. I'm not recommending anybody do what I did, but I think some of this worry about lead is a bit over blown. When I was a kid, I had a single shot Crossman pellet rifle. If I wanted a quick second shot, I carried the lead pellets in my mouth. I'm 80 years old, and at least smart enough to barely use this bloody computer. We also played with mercury in our hands, turning pennies silver. Everywhere a Civil War battle was fought, there is -- well, until metal detectors -- tons of lead in the ground. The patina in on those old bullets is caused by oxidation of the lead, which also seals off the rest of the lead in the bullet from oxidizing, and escaping into the surrounding area. I've never heard of people living on those battle fields being poisoned by lead. I cast lead bullets to use shooting my muzzle loader firearms and handle lead bare handed all the time. I'm not saying lead isn't dangerous, but it's not a rattle snake that is going to bite you, or it's not like finding unexploaded ordinance, it isn't radio active, and it doesn't seem to me to be near as dangerous as some environmentalists are trying to make out.
