Mercury is a toxic element, and is currently an unavoidable part of CFLs. Each CFL contains about 5 mg of mercury, equivalent to the tip of a ballpoint pen. For comparison, those old mercury thermometers we all used as kids had 50-100 mg of mercury in them. And like the thermometers, the mercury in CFLs is released only if the glass is broken. Broken bulbs release mercury vapor and a mercury- containing phosphor powder.
