Since all the fuss about acid rain in the 80's, there are so little
sulfur emissions (either as SO2, or via other intermediates as
SO3-), I don't think we need to worry about that any more (sorry for
the double post.... iPhone is not always the best ;-)...)

BTW, I also remember to read that sulfur di/trioxide in atmosphere is
another main cause of deterioration (forms sulfuric acid?)

As far as I can read, acetic acid is the main cause of paper
deterioration, so it has to be thoroughly washed out of
paper when done.
