How can we get lead poisoning other than in our plumbing system or paint,what are the symptoms?

old newspaper(s) ink. When I was young I used to be a paperboy. After a few years the paperbag (sack) got so messy with news ink that it was rubbing against my hip and leg. Soon I delveoped rashes. turned out it was the lead in the older newspaper ink.

There maybe still a lot of printed materials out there with lead based ink in them.

A very ususl source is toys, sometimes plates painted with lead-based paint, The symptoms are vomiting, haedaches, cramps etc. Check out this site for more info! It's really good.
