We've all heard that using compact fluorescent light bulbs (CFLs) is one very simple thing we can do to have a big impact on the amount of energy we use. In fact, if every American home replaced just one incandescent light bulb with an ENERGY STAR qualified CFL, we would save enough energy to light more than 3 million homes for a year, more than $600 million in annual energy costs, and prevent greenhouse gases equivalent to the emissions of more than 800,000 cars.
No mercury is released as long as the bulbs remain intact – exposure is only possible when one has been broken. Still, there are definite precautions you should exercise when using CFLs, particularly with their disposal.
To locate a hazardous waste collection and recycling center in your area visit the EPA's bulb recycling page or Earth911.org. Your local electric company may also have recycling information on its website.
Health Effects of Mercury Exposure
Elemental mercury usually causes health effects when it is breathed in as a vapor and absorbed by the body through the lungs. Some symptoms of mercury poisoning can include tremors, mood swings, muscle weakness, and headaches. With higher exposure there may be serious effects, including death. If you are worried about your exposure to mercury, please consult your doctor.
Something as easy as replacing your light bulbs can make a significant difference in the amount of greenhouse gases emitted by power plants, not to mention the savings you'll see on your electric bill. Just make sure you're taking the necessary steps to ensure your safety – and the environment's.
