Compact flourescent light bulbs are often touted as an energy efficient, environmentally friendly alternative to traditional bulbs as well as a money saver. But there’s a dangerous dark side to CFL bulbs: they contain a small but dangerous amount of mercury.

CFL bulbs contain about 4 milligrams of toxic mercury in each bulb. The mercury doesn’t pose a threat if the bulb remains intact, but improper use and disposal leads to broken bulbs and mercury contamination.

The amount of mercury in CFLs is relatively small when compared to other high risk contaminants, and their benefits may outweigh the risk as long as you use caution:

• Handle CFL bulbs carefully to avoid breaking.
• Contact your local waste management agency or visit the official EPA CFL bulb recycling page for information on proper disposal and recycling.
• In the event of a broken bulb:

1. Shut off automatic ventilation systems to avoid contaminating air throughout your home and air out the room with an open window before cleaning.
2. Carefully sweep and place fragments and powder in a glass jar with a seal. Use tape to carefully remove all of the powder.
3. Vacuum only if absolutely necessary, and seal the contaminated vacuum bag in airtight plastic when finished.
4. Do not washing clothing or bedding that has come in direct contact with the mercury powder. Dispose of them according to your state’s requirements for disposal of mercury-contaminated trash.
5. Dispose of cleaning materials according to your state’s disposal requirements.
6. Wash hands immediately after handling all materials.

Mercury exposure isn’t limited to CFL bulbs. There are many ways that you could be exposed to this dangerous toxin. A daily regimen of chlorella ensures that any mercury you may be exposed to is safely and naturally removed from your body. Visit GreenPath Supplements for more information.
