FYI, here is a FoxNews follow up on the subject.  What's interesting is that they claim that there is a net gain to the environment because coal burning also contains mercury & the CFL bulbs contain less than the amount of coal burned to power normal incandescent lights.  Here is something from the coal industry on the subject.

A detailed discussion of the dangers of mercury in cfls is here.

From the Boston Globe today:
source: ...

The study recommended that if a compact fluorescent breaks, get children and pets out of the room. Ventilate the room. Never use a vacuum, even on a rug, to clean up a broken compact fluorescent lamps. Instead, use stiff paper such as index cards and tape to pick up pieces, and then wipe the area with a wet wipe or damp paper towel. If there are young children or pregnant woman in the house, consider cutting out the piece of carpet where the lamp broke as a precaution. Place the shards and cleanup debris in a glass jar with a screw top and remove the jar from the house.

Thing is these things do not break easily.  There needs to be either an unusual accident or an intentional act.  These are far less dangerous than the old mercury thermometers based on the amount of mercury they contain and how unlikely an accidental breakage actually is.  Me thinks sombody is doing a bit of fear mongering here.  Perhaps the tungsten miners.  

In any case i think that eventually lighting will evolve to solid state LED's ... more efficient and nontoxic.   I've been playing around with the latest super bright LUXEON Rebels from Phillips. 
Problem is they are so small i can't figure out how to solder them into a fixture.


Mark de LA says
What would be ironic would be if you could find a heat resistant glue & glue them to outside of an old lightbulb & somehow put the electronics in the screw in base; maintaining the continuity of the parallel wiring necessary to run them.
