My dear sir if an individual spent their entire life being concerned with
negative possibilities as against first hand actualities, then they would
most certainly have developed a substantial facial twitch.

I do not have a facial twitch and I do not concern myself with that which
has not yet been seen to happen.

But there's a logical flaw in saying "I never saw it, so it doesn't exist".
Storage conditions -- temperature, humidity, presence of fungal spores --
will
have an influence. I have seen enough mouldy glass mounted slides to take
this
issue seriously (I live in the sub-tropical zone). As to out-gassing, I
would
keep an ear open to what the conservators say.
