    I only glanced at that doco, but most photographic chemicals use formaldehyde in a solution. Even at C41 process temperature the amount evaporated into a gaseous form would be miniscule in a typical sized darkroom, especially if ventilated by opening a window.

    I never worry much about C41 colour stabilizers when processing film - I just keep the window open and wash my hands

    very true of course, but if one has a choice then the less toxic route is always best. And remember that the most problematic source of formaldehyde is a solid - urea-formaldhyde.

    <sigh> you mis-read me completely. Look at the quoted statement (included in my post)Originally Posted by gbroadbridge:

    My point was that even in a solid, formaldehyde gas escapes into the surrounding environment.

    Now say you're sorry
