Lead leads to above normal hostility and aggression. Lead paint, lead petrol, lead pipes - all must go. And maybe some kind of protection at shooting ranges?

Adequate ventilation will reduce the lead exposure. There are alternatives to using lead for bullets which would eliminate the exposure.
Nice. What are the bullet alternatives?
And shotguns are often required to use steel or some other non-toxic shot instead of lead shot, when they are used for hunting due to contamination.
That’s big. Absolute must for health
Except primers have lead, dusting your hands and face with lead, which I wouldn't be surprised if worse than ingesting some lead shot. And it's far more difficult to find ammunition with lead-free primer than lead free bullets.
