Keep in mind that metallic lead is so stable bullets are left in shooting victims all the time with no issue.
The sinovial fluid in joints is about the only thing that can leach lead.
Even eating pieces of lead is not going to result in any significant absorption unless the lead is a finely divided powder with a huge surface area.
You need some very specific chemistry to release lead from the metallic form into the ecosystem, and it rarely occurs.
Lead oxides are very stable, and form on the surface preventing any further contact.
