Hello All,
There seems to be varying opinion on how to dispose of very dilute solutions of ethidium bromide. The concentration in question is 0.5 micrograms/ml of buffer. By hazardous waste definition, this would not be considered a hazardous waste, but I believe some of our California universities and colleges recommend filtration of the ethidium bromide before disposal at any concentration.
Any guidance would be very much appreciated.
Sincerely,
