  • mercury, which is highly toxic
  • depending on the state or country involved, the use of CFLs may actually increase total mercury released to the environment.
  • The reason is that power plants use different fuel sources, which release different amount of mercury into the air
  • In some locations that use cleaner coal, or that have few recycling options, the mercury leaked into
  • environment from landfilled CFLs could actually surpass the amount saved by using less electricity from power plants.
  • Compact fluorescent lamps (CFLs) are the light bulbs of choice

  • are far more efficient than
  • traditional bulbs, which waste about 90 percent of their energy on heat. Many people have significantly reduced their electric bills by switching to CFLs. But there are situations where CFLs are not the best option.
  • CFLs work on the principle of fluorescence
  • An electronic ballast in the base
  • of the bulb generates an arc between two electrodes inside a glass t
  • filled with gas
  • The arc excites mercury atoms in the gas so that they give off
  • ultra-violet (UV) energy
  • Cleanup and Recycling of CFLs
  • Although the amount of mercury in a CFL is much less than that in a can of tuna, CFLs are considered household hazardous waste. By law, they must be either be recycled or taken to an approved hazardous waste disposal site.
  • These steps include airing out the room, putting all debris and cleaning materials into a sealed jar or double plastic bag, and avoiding the use of brooms or vacuum cleaners that might stir mercury into the air.
  • Protection website recommends disposing of the carpet, rug or bedspread on which a CFL breaks. It also suggests that CFLs might not be appropriate in rooms used by infants, small children or pregnant women, who are more susceptible to mercury poisoning.
  • Many hardware stores and local disposal sites accept CFLs for recycling, and some companies now sell pre-paid shipping boxes addressed to recycling plants. Unfortunately, not everyone has easy access to these options, so about three out of four CFLs end up in landfills, where the mercury gets leached into the soil and groundwater.
  • CFLs on Dimmer Switches
  • dimmer switches. Using these switches saves energy by reducing the amount of power needed for lighting. But most CFLs do not work on dimmer switches, and may actually damage this kind of switch.

(Ultraviolet light rays are the light wavelengths that can cause sunburn and skin damage.)
  • What compact fluorescent light bulb do I buy to replace an incandescent (regular) bulb?While a regular (incandescent) light bulb uses heat to produce light, a fluorescent bulb creates light using an entirely different method that is far more energy-efficient — in fact, 4-6 times more efficient. This means that you can buy a 15-watt compact fluorescent bulb that produces the same amount of light as a 60-watt regular incandescent bulb.
  • Don't worry about the math, though — we make it easy for you to figure out which compact fluorescent bulb to buy by displaying the equivalent regular watts you're used to prominently on the package. Just look for the wattage you would normally buy in a regular bulb.

  • CFL containing 5 mg of mercury breaks in your child’s bedroom that has a volume of about 25 m3 (which corresponds to a medium sized bedroom). The entire 5 mg of mercury vaporizes immediately (an unlikely occurrence), resulting in an airborne mercury concentration in this room of 0.2 mg/m3. This concentration will decrease with time, as air in the room leaves and is replaced by air from outside or from a different room. As a result, concentrations of mercury in the room will likely approach zero after about an hour or so.

  • elemental mercury vaporizes readily (essentially becomes a gas) and can thus be inhaled into your lungs. Breathing elemental mercury into your lungs is generally more dangerous than if you ate the mercury or absorbed it through your skin. Once inhaled, the mercury vapor can damage the central nervous system, kidneys, and liver.
  • These toxic effects are why any mercury spill should be handled carefully, including one that results from a CFL breaking
  • This is because CFLs contain relatively small amounts of mercury -- EPA estimates this amount to be 4-5 milligrams (mg) in a typical CFL
  • . A spill of this amount of mercury is not likely to present any excess risk to you or your family
  • Under these relatively conservative assumptions, this level and duration of mercury exposure is not likely to be dangerous, as it is lower than the US Occupational Safety and Health Administration (OSHA) standard of 0.05 mg/m3 of metallic mercury vapor averaged over eight hours. [To equate these values, we could estimate the average indoor airborne mercury concentration for 8 hours, beginning post-spill at an estimated starting value of 0.2 mg/m3 and decreasing from there. If one assumes the the air exchanges completely in one hour (a fairly standard assumption), then the 8-hour average concentration would be 0.025 mg/m3.]
  • Even though mercury from the broken CFL is not likely to be dangerous, it would be wise to take extra precautions to minimize mercury exposures
  • The US EPA publishes guidelines about the specific steps that you should take to clean up mercury in the event that a CFL breaks in your home
  • Briefly, EPA recommends that (1) you immediately open windows to reduce mercury concentrations inside your home; (2) you do not touch the spilled mercury; (3) you clean up the broken CFL glass carefully and immediately (but not with your hands or a vacuum cleaner), and (4) you wipe the affected area with a paper towel to remove all glass fragments and mercury. EPA further recommends that you place the paper towel and glass fragments in a sealed plastic bag and bring the sealed bag to your local Household Hazardous Waste (HHW)Collection Site.

  • All of this needs to be done to protect people from the tiny amount of mercury in one fluorescent light bulb. Which begs the question, are these lights really safe and are the risks worth it? Another equally important concern is what happens to the environment – the air, soil and water – when tons of discarded bulbs, along with the mercury, are dumped into local landfills?
  • The threat posed by billions of broken CFLs lying in landfills has resulted in some communities requiring their citizens to discard used and broken CFLs in designated recycling centers or in a hazardous-waste collection facility.
  • Given the known deleterious effects caused by mercury, it would seem logical to assume there will be some unintended consequences resulting from the switch to compact fluorescent lights. Only time will tell how significant those consequences will be.

Some Comfort About Broken CFLs - Science News - 0 views

  • one of those highly efficient CFLs I’d installed all over the house. She didn’t shatter the whole bulb, just a roughly 3-inch segment of the swirly glass, which (naturally) embedded in the fibers of her carpet. Having heard me warn endlessly of how we should be careful in handling these bulbs — since they contain mercury — she wanted to know what kind of damage control was called for. I only wish I knew then what I do now. It wouldn’t have changed how we cleaned up the mess, but we would have slept a bit better that night.
  • New data from Yadong Li and Li Jin of Jackson State University in Mississippi help put concerns about mercury from broken bulbs in perspective. They measured the mercury present in both new and used CFLs and recorded the continuous emissions from ones that they intentionally broke.
  • Keep in mind, Li notes, a CFL's elemental mercury is not in vapor form unless the lamp is on with a current running through it. Otherwise, the mercury resides along the inside of the glass. And it's from there that the mercury will slowly volatilize once exposed to air. So another lesson: Breaking a CFL while it's turned on can initially disperse a bigger puff of mercury vapor into the air than if its glass is damaged while the bulb is off, Li says
  • ...10 more annotations...
  • A more disturbing finding was how long a broken CFL can continue to release toxic vapors: a minimum of 43 days (which is how long Li and Jin ran their tests with bulbs from three different manufacturers). The engineers computed how much of each bulb’s starting mercury had been lost during that time (which wasn’t easy, since starting values and release rates both varied broadly between bulbs). Their calculations indicate that each CFL still contained enough residual elemental mercury at the end of their testing to continue releasing the toxic substance into the air for at least 10 more days, and in one instance, for 85 more days
  • If not cleaned up, the bulb with the largest initial store of mercury could have spewed 1 milligram of the toxic metal into a room's air within 25 days; another could have reached that level within about 40 days. Li and Jin cited data by others indicating that the release of 1 milligram of mercury vapor into a 500 cubic meter room can yield air concentrations 10 times the current recommended limit for a child.

Facts About CFLs - Earth911.com - 3 views

  • Sealed within the glass tubing of CFLs, is a very small amount of mercury. On average, CFLs contain four milligrams of mercury – about the same amount that would fit on the tip of a ballpoint pen. This may seem high to some, but keep in mind that old thermometers contained about 500 milligrams of mercury. Mercury  allows the bulb to be an efficient light source. No mercury is released when the bulbs are intact or not being used.
  • Thanks to a commitment from members of the National Electrical Manufacturers Association (NEMA), most makers of light bulbs have reduced mercury in their products
  • This has been made easier by advances in technology. Based on these two factors, the average mercury content in CFLs dropped at least 20 percent in the past few years. Some manufacturers have gone as far to have dropped their CFLs’ mercury content to 1.4 to 2.5 milligrams per light bulb.

  • They're breakable, contain toxic material, and are becoming increasingly commonplace. But fears of mercury poisoning from new energy-efficient fluorescent bulbs are overplayed, experts say.
  • But CFLs' cool-burning illumination is made possible by a pinch of poison—about five milligrams of mercury sealed inside every glass tube—and the need for the element is unlikely to change anytime soon. Mercury is a potent neurotoxin and long-lived environmental contaminant, and even the small amount present in CFLs poses a problem. When the bulbs break, either in the house or at a waste disposal site, their mercury content is released.

  • These critics have charged environmentalists with being uncharacteristically "pro-mercury" when it comes to the lights. The critics often cite the recent story of a resident of Ellsworth, Maine, who amassed a clean-up bill of more than 2,000 U.S. dollars by shattering a single CFL in her home. The story originally appeared in the Ellsworth American and quickly spread to other newspapers, such as Canada's National Post and the Washington Times.
  • But the enormous bill came about as a result of bad advice—a fact often omitted in follow-ups to the original article. "There's a lot of misleading information out there," said Joel Hogue, president of Elemental Services and Consulting, an Ohio-based company specializing in the cleanup of sites contaminated with mercury. "But when people learn the facts

  • Like with many other household products, Hogue said, the use of CFLs requires some commonsense precautions. But if a bulb breaks, his company's clean-up services are not required.
  • There's an extremely small amount of mercury in those bulbs," Hogue said. "It's a very minimal risk" and can easily be cleaned up at home. One CFL contains a hundred times less mercury than is found in a single dental amalgam filling or old-style glass thermometer, according to the U.S. Environmental Protection Agency (EPA).
  • Long billed as a "green" product for environmentally conscious consumers, compact fluorescent light bulbs (CFLs) are quickly becoming the norm in household lighting—and may soon replace traditional incandescent bulbs altogether.

The Problems with Compact Fluorescent (CFL) Bulbs - 0 views

  • Mercury content Like all fluorescent lamps, CFLs contain a small amount of vaporized mercury. Mercury is poisonous even in small amounts. If a bulb is broken, then there is the risk being exposed to dangerous mercury vapors. Though the bulbs are meant to be recycled, many are almost certain to end up in landfills and dumps – polluting the grounds, air, and water with small amounts of the poisonous substance
  • CFL bulbs are often hailed as the green replacement of the older incandescent bulbs. CFLs use less energy and can have a lifespan of around ten times that of incandescents if not turned on and off repeatedly over short periods of time. These are all well and good, but there are some drawbacks to the CFLs that people should know about before making the switch

  • Solution: I've never had a problem with a bulb from a major manu­facturer. Now, I spend the extra few bucks for
  • name-brand product.
  • Problem: The bulb failed because it was installed in an inappropriate lighting fixture, one that it wasn't rated for.* Solution: Read the bulb package's fine print. Some bulbs are meant to be used only in downward-facing fixtures, others in enclosed and recessed, three-way or outdoor fixtures. Additionally, there are CFLs rated to be oper­ated by a device such as a dimmer, timer or photoelectric eye.
  • Problem: The bulb wears out prematurely because it was turned on and off frequently, or because it experienced excessive vibration or impact--for instance, a lamp in a foyer might get a jolt with each slam of the front door. * Solution: Although manufacturers are developing tougher CFLs, this is one area where the century-old incandescent bulb has them beat. Check out Heavy Duty Rough Service bulbs from Feit Electric Company. Each bulb has a reinforced filament rated for 3000 to 5000 hours
  • It seems that while new compact fluorescents save a lot of power, they're a lot more fickle when it comes to installation than their incandescent brothers. Here are three common problems with CFLs and how to avoid them.

Once in a landfill, bulbs are likely to shatter even if they’re packaged properly, said the Solid Waste Association of North America. From there, mercury can leach into soil and groundwater and its vapors can spread through the air, potentially exposing workers to toxic levels of the poison.

Compact Fluorescent Light Bulb Mercury Warning - 1 views

  • What to Do if a Fluorescent Light Bulb Breaks Fluorescent light bulbs contain a very small amount of mercury sealed within the glass tubing. EPA recommends the following clean-up and disposal guidelines: Open a window and leave the room (restrict access) for at least 15 minutes
