The appropriate amount of amidol (2,4-diaminophenol) recommended for use
with PMK, is in the region of 0.05 to 0.1 g/litre. Anything over that
recommended amount will cause increased fog levels. I doubt that 0.07g/l
would produce enormous amounts of any "invisible" gas.
While my use of amidol goes back to about 40 years ago ... used primarily
as a print developer, I gave it up when the price went too high as the
amount of oxidation in the container increased and the difficulty of
acquisition became greater. If I could get an easy and affordable supply, I
would gladly go back to contact printing large format negatives on Kodak's
Azo paper.
I would doubt the addition of amidol would make film processing any
cheaper, although the increased EI (+/- 1/2 stop) might in some rare times,
make it worth the effort
