What chemicals fog paper and film?

[tkamiya]

I understand certain chemicals fog film and paper. I know I should not store Brown toners and Sepia toners (which both contain sulfide/sulphide components) in the same room as film/paper.

Is it correct that sulfite and sulfate compounds are safe as far as fogging risk is concerned? What else used in common B&W processing pose this fogging danger?

I am starting to collect various toners and raw ingredients (that will make up dev, fix, hca, etc) that I'm a bit concerned.

No problem. You keep the top on the bottle.

Let me ask this way then.

Let's say I was less than fully paying attention one day and left the bottle open. Or worse, spilled it in my darkroom. What chemical has a potential of screwing up my stock of film and paper stored in and around my darkroom?

(there was a url link here which no longer exists); PE gives a bit of a comprehensive list.
