Could be, but i think it unlikely that you would digest PbCO3 (or PbO,  
or lead chromate) with an organic acid. You could check the solubility  
products in the literature to be sure. I looked up lead paint, rather  
than relying on memory. They used all three of the species I just

Always a good possibility. Being a physicist, I'd find a portable XRF  
unit, or find a lab on campus that had one. XRF will give you proof  
positive of the presence of significant quantities of lead, in any  
oxidation state, in any compound. Hell of a lot easier than chemistry,  
if you've got it. :D
