Thanks for the thread, I was, however, concerned to read the following (Google search lexan leach):

Quote:
A University of Missouri study in the July 2003 issue of Environmental Health Perspectives further confirmed the Hunt study's conclusions.

In addition to determining that used, or discolored, polycarbonate plastics leach high amounts of BPA at room temperature, this study found that detectable levels of BPA leach from brand-new polycarbonate plastics at room temperature.


Specifically, the room temp leaching of the BPA looks to be of interest. I find it difficult to accept the arguments from Nalgene, of course they will defend their product. I'd prefer an independent confirmation of safety or otherwise.
