> Old houses have lead

So I’ll accept that lead pipes are not great but how bad is lead paint really?

Specifically, if you have lead paint underneath several layers of more modern titanium paint, what is the lead poisoning risk? I thought the more significant risk with lead paint was from paint flaking into dust, especially for painted iron which comes off as the iron rusts.

Lead paint that has been covered in layers of latex paint is safe.

Most of the hazard of lead paint comes from kids eating paint chips in poorly maintained buildings or contractors sanding it off and contaminating the building.

Also, lead paint tastes sweet, so leaded paint chips are extremely appealing for small children to eat.
