Wow! What a compelling picture. There are a number of companies that
make archival boxes specially designed to absorb offgasses, but I've
never seen such a visually strong argument for using them before. If you
were interested in testing the pH of the areas, there are various,
relatively simple tools available from archival suppliers, including
strips like these ones:
for one, would be interested in the results.
