And used fixer is the main one to be concerned with. I hope we are all saving our old fixer and removing the silver. A local lab allows me to dump mine through their silver recovery system to our mutual benefit. Obvously compounds with cyanide are bad, but they are not so common. I suspect that a bit of ppoking around on the web would provide a lot more info. Enjoy your new house and darkroom.
