Studies by instititions in my area have revealed that a number of the 
biosafe scintillation cocktails contain elevated levels of Mercury, 
thus rendering sink disposal illegal.

Specifically, Amersham Biodegradable Counting Fluid BLS was analyzed 
and the sample contained 43 ppb of Mercury.  This exceeds our local 
(Massachusetts Water Resources Authority) effluent concentration 
limit of 1 ppb.

I'm not sure if other similar "safe" cocktails have been analyzed for 
hazardous materials content, but if anyone else has some experience, 
please share.
