Thanks for the reply.
Could you direct me to some authoritative sources?
A quick Google search quotes the EPA as saying the leaching of BPA is a "concern" but the primary source of exposure appears to be from plastic bottles, less so for paper, save for perhaps register receipts.
Other Goggle searches for "paper chemicals leaching" don't produce much else other than scientific "papers" discussing the leaching threat from other materials.
Thanks again!
