According to the Union of Concerned Scientists, the mercury in a CFB  
is less than that which is kept out of the atmosphere by the coal not  
burnt when you use a CFB instead of an incandescent bulb.

A CFB contains "about five milligrams" of mercury, but "the average  
existing coal-fired power plant emits 13.6 milligrams of mercury to  
power a typical incandescent bulb, but only 3.3 milligrams for a  
CFL." (Spring 2007 issue of "Earthwise, News and Ideas for UCS  
Members and Activists")

Thus, if your electricity comes from coal, the CFB introduces less  
mercury into the environment that the incandescent bulb. Not to  
mention that the avoided mercury is distributed into the air, whereas  
CFBs can be sequestered from the waste stream through education and  
enforcement, much as batteries and computer monitors are.
