A good reason to recycle those energy saving Compact Flourescent Light Bulbs!

Los Angeles Times report

Unrecycled New Light Bulbs Release Mercury into the Environment,0,3406825.storyThe nation’s accelerating shift from incandescent lighting to a new generation of energy-efcient bulbs is raising an environmental concern: the release of tons of mercury every year.The most popular new bulb–the compact fluorescent light bulb, or CFL–accounts for a quarter of new bulb sales. Each contains up to 5 milligrams of mercury, a potent neurotoxin that’s on the worst-offending list of environmental contaminants.Demand for CFL bulbs is growing as government mandates for energy-efficient lighting take effect, yet only about 2% of residential consumers and one-third of businesses recycle the new bulbs, according to the Assn. of Lighting and Mercury Recyclers. As a result, U.S. landfills are releasing more than 4 tons of mercury annually into the atmosphere and storm water runoff, according to a study in the Journal of the Air and Waste Management Assn.
