Compact fluorescent light bulbs: Mercury a concern when CFLs aren't recycled

Compact fluorescent light bulbs: Mercury a concern when CFLs aren't recycled - latimes.com
Energy-efficient CFLs are increasingly popular but few people recycle the bulbs. As a result, U.S. landfills are releasing more than 4 tons of mercury annually into the atmosphere and storm water runoff, a study says.

The nation's accelerating shift from incandescent lighting to a new generation of energy-efficient 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.
