Hello Judy!
Just few remarks. Selenium toners may be based on sulfides or sulfites. The
first one smells like a rotten egg, the second no. H2S is a strongly toxic
gas, therefore ventilation is a must. Selenium in small quantities is
important part of diet, more concentrated is toxic. Please, spare me from
typing all that stuff. If you have slip/ppp (gopher or www) Internet
account, get relevant MSDS from any site that offers them. It's true,
selenium is toxic in a powdery form. In a solution is as good as for example
sulfides ;-{0. So, once mixed, probably enough safe for not to wear a mask.
