Lead-free chalk

[neo_vega]

I recently came across some web-sites that seem to indicate that if you have a pool table at home, you should switch to lead-free chalk.
Has anyone researched this here?
Does anyone know where we can get lead-free chalk. All my web searches have returned articles about why you should use lead-free chalk.. but alas no information on where you can get that.

Here's the link.

None of the chalk manufactured in the U.S. has any lead in it. Master is the best...
