This may be a dumb question…Or, maybe it is because I live in Michigan surrounded by the Great Lakes and stringent waste restrictions or maybe I am just overly cautious. 


Would you collect micromolar crystal violet solutions from a traditional kinetics lab as shown here:


Does anyone know of any references to concentrations of carcinogens or environmental hazards (of course, depending on what SDS you look at; I always choose the scariest one) that are considered non-hazardous, maybe related back to its LD50 or something?


Thank you for your infinite wisdom,
