gases in my workflow

Hello there,

If this is my workflow:

1-Developer (phenidone based)

2-Citric acid stop bath

3-Neutral fixer

+4 Selenium toner

Could anyone say which are the gases emited in my darkroom?


Thanks so much for your coments,

Yiss

Depending on the specific product / process detail & temperature you are using, usually nothing to worry about.

Thanks a lot for your reply. I am aware the health risks would not be relevant, specially with that chemistry (with the obvious exception of selenium). I have read so much discussion about this that I would like to bring some light to this. I have gastec equipment I can use and i would like to measure some gases so we can really know what goes on at least for a workflow configuration like mine .
I would appreciate then some input here if posible.
According to the information I have, there could be:

Sulphur dioxide
Ammonia gas

THANKS SO MUCH!

You have identified the most likely. Add to that Hydrogen Selenide as a possible gas.
