TIP FOR RECYCLING YOUR LIGHTBULBS: CFLs contain a small amount of mercury and should be disposed of properly — ideally, recycled. According to the Environmental Protection Agency, CFLs contain an average of five milligrams of mercury, which increases the bulb's efficiency. But that also means you can't just trash them; CFLs must be properly recycled. Ikea is one national retailer with a recycling center in their stores to take old CFL bulbs back for recycling. Also, visit EARTH911.org and type in "CFL" and your city/state to find a recycling center near you.
Potentially poisonous
Mercury is key to making compact fluorescent light bulbs (CFLs) efficient. Electricity sent through the lamp, which contains mercury vapor and an inert gas such as argon, zaps the mercury, setting off a reaction that creates light. The reaction is more efficient at converting power into light, with less residual heat than a normal incandescent bulb.
Each CFL contains about 5 milligrams of mercury, just enough to cover the tip of a ballpoint pen. By contrast, a mercury thermometer contains 500 milligrams of mercury.
The silvery substance can be dangerous even in small quantities, though, because it can be inhaled or absorbed through the skin, and it damages the central nervous system.
Small amounts can also build up in the environment if the bulbs are thrown in the garbage and break or are incinerated. Mercury can enter the food chain and accumulate, for example, when big fish eat smaller fish that contain mercury, as is already the case with tuna and other large fish.
No big deal. Our socialized healthcare system will take care of this I'm sure. The ends justify the means I guess. Well, they do for this cause, but not for the Patriot Act or Iraq or anything of real substance and importance. For unproveable, faith based, faux crisis' it's okay. I get it.
