I had a family member poisoned by a spouse about 8 years ago, she tested in at 156 parts.
Needless to say, she passed away two years later, after suffering from multiple types of cancers. Her cell DNA was so screwed up they were starting everywhere.
Lead is not something to mess around with, without being careful. BTW, he was a reloader and got the lead from his castings.
