When is someone going to mention that fluorescents contain that eeeeeeeevil MERCURY?

An interesting analysis- CFLs contain 4mg of Hg each, but may reduce Hg emissions to the environment overall by reducing the amount of coal burned.
I'll need a lot more data before I can comment on the truth of that, but it sounds intersting.
