mixed waste stuff

["Charles Meyer" <CMEYER@brc1.tdh.state.tx.us>]

Some questions still persist in my mind about whether or not certain 
compounds containing source material might qualify as mixed waste.
I have encountered the following compounds(uranyl nitrate or acetate, 
and thorium nitrate) in the following situations research laboratories, public school chemistry storerooms, 
commercial labs, and illicit drug labs(by correspondance only!) I'm 
not a chemist, but have been told that at least thorium nitrate and 
posssibly(?) uranyl nitrate might be strong oxidizers and therefore 
qualify as hazardous waste because of that property.  Also uranium is 
a chemically toxic agent at certain concentrations, which might also 
qualify it as a hazardous waste. If these properties do qualify the 
above mentioned compounds as hazardous waste once declared, then it 
sounds like mixed waste to me.    Comments?
