Digital BW, The Print

Hogarth  - 

Well, probably.  But, is Wilhelm testing in a manner that would catch this?  

A print properly framed behind UV glass, while not air tight, won't have much air flow around it.  So, I'm wondering if the airborne pollutants are actually as much of a factor as you indicate.  And, airborne pollutants can enter from the back of the print, as well.
