Is the production of film darkroom toxic?

Use conventional chemicals (developer, developer stopping agent, fixing agent, etc.). ) You can basically ignore this problem, as long as you don't drink it in your mouth! Just skin contact or breathing, the harm can be ignored! However, some liquids do have a little taste, such as stopping the liquid, which is not a big problem. As long as the darkroom has certain ventilation conditions, the impact of this problem on health can be ignored.

I've never heard of darkroom workers suffering from occupational diseases.
