Have the government and General Electric lied to us? Action Alert!
The Energy Independence and Security Act of 2007 (EISA) mandates the phase-out of incandescent light bulbs, and favors energy-efficient compact fluorescent light (CFL) bulbs.Sounds good—until you realize that CFL bulbs contain mercury, and mercury poses a significant cancer risk. A new study shows that CFL bulbs also emit high levels of ultraviolet radiation—specifically, UVC and UVA rays. In fact, the UV rays are so strong that they can actually burn skin and skin cells. Experts saythe radiation could initiate cell death and cause skin cancer in its deadliest form—melanoma.
In every bulb the researchers tested, they found that the protective phosphor coating of the light bulb was cracked, allowing dangerous UV rays to escape. Healthy skin cells exposed to CFLs showed a decrease in their proliferation rate, an increase in the production of reactive oxygen species, and a decrease in ability to contract collagen.
On top of that, it’s a sad fact of life that light bulbs break. How do you clean up the mercury after a bulb breaks? The Institute for Molecular and Nanoscale Innovationmeasured the release of mercury vapor from broken bulbs. They recorded concentrations near the bulb of up to 800 mcg/m3, which is eight times the average eight-hour occupational exposure limit allowed by OSHA (100 mcg/m3).
Even more shocking, the recommended limit for children is a mere 0.2 mcg/m3. A child exposed to a broken CFL bulb will receive eight thousand times the recommended amount of mercury vapor!
A broken 13-watt CFL bulb will only have released 30% of its mercury a full four days after it is broken—the remainder is trapped in the bulb. So picking up shards with your bare hands or leaving them in poorly ventilated room while you ponder the best disposal method is a particularly bad idea.
Unfortunately, there is no good solution for cleaning up after a broken CFL bulb. Researchers at Brown are testing a cloth made with a nanomaterial (nanoselim) that can capture mercury emissions for proper disposal. But until this is commercially available, it is best to avoid CFLs altogether. And how will we dispose of the clean-up cloth?General Electric claims that CFLs don’t produce a hazardous amount of UV radiation, and that UV is far less than the amount produced by natural daylight. The truth is that all compact fluorescent lights bulbs contain mercury vapor. Once that vapor is hit with an electric current, it emits a great number of UV rays. UV rays are theoretically absorbed by the layer of phosphor that coats the bulbs—but the signature twisted spiral shape makes these bulbs more prone to cracks in the phosphor, which dramatically increases UV/mercury exposure. Researchers found cracks in almost all bulbs purchased from retail stores, indicating that it is a standard design flaw of these bulbs.
CFL bulbs contains other cancer-causing chemicals as well. German scientists found that several different chemicals and toxins were released when CFLs are turned on, including naphthalene (which has been linked to cancer in animals) and styrene (which has been declared “a likely human carcinogen”). A sort of electrical smog develops around these lamps, which could be dangerous.
CFLs are supposedly better for the environment, but according to the Association of Lighting and Mercury Recyclers, 98% of CFLs end up in landfills—creating a mercury build-up that can escape into our soil and waterways.
We’re happy that the federal government is tackling environmental problems, but this “solution” is especially short-sighted—and not unlike the national smart meter push, is creating serious health risks in the long-term.
Worse, soon consumers won’t have the option to buy incandescent lights—they simply won’t be available. The government hasn’t placed an outright ban on incandescent light bulbs. Section 321 of EISA mandates higher efficiency standards for general service lamps. But these standards are high enough that most commonly used incandescent bulbs just won’t meet the new requirements. EISA will effectively eliminate 40-, 60-, 75-, and 100-watt incandescent bulbs. The new efficiency levels will be in full force by 2014.
Even the United Nations has acknowledged the problem of mercury in CFL bulbs, and has instated a ban on certain types of CFLs. We won’t know the full implications of that ban until the treaty is made publically available.
The good news is that CFLs are not the only energy-efficient bulbs out there. There are also light-emitting diodes (LEDs), which are mercury-free—though LEDs emit blue light, which can be disruptive to sleep, as we noted in our 2012 article.
Electricity Saving Light Bulbs Can Cause Skin Cancer, Save Your Kids
Several scientists, led byMiriam Rafailovich at Garcia Materials Research Science and Engineering Center at SUNY Stony Brook, did studies on many different types and brands of Compact Fluorescent Light Bulbs from across Long Island to determine the amount of Ultraviolet rays the bulbs put out in a home. They were disturbed just how bad the light bulbs phosphor coatings were. Without a proper coating as has already been determined it causes them to give off a significant level of Ultraviolet C and Ultraviolet A.
There are a few studies that indicate that Ultraviolet C is the most dangerous wavelength that can cause skin cancer.
“Our study revealed that the response of healthy skin cells to UV emitted from CFL bulbs is consistent with damage from ultraviolet radiation,” said Rafailovich.
Consumers should be concerned when using compact fluorescent light bulbs to save on energy because many of the bulbs out there have thin coatings that do nothing to protect you against skin cancer. You most definitely want to avoid using any UV light bulb at close range. In all scenarios where they could be used make sure there is an additional glass barrier of some kind between the bulb and your skin.
In the research done by these scientists they were able to verify that healthy human skin tissue cells were damaged. There is a cell known as a fibroblast that you will find in connective tissue that creates things like collagen and keratinocytes. These cells that are epidermal layer cells were damaged by the CFL radiation.
Healthy human skin tissue cells, including fibroblasts, a type of cell found in connective tissue that produces collagen, and keratinocytes, an epidermal cell that produces keratin, were damaged by the Compact Fluorescent Light radiation.
When comparing the new CFL bulbs with that of the Old-fashioned incandescent light bulbs of the same intensity there was absolutely no damage to the cells.
Now good luck getting this information out to the public. There are plenty of ego’s that have championed CFL bulbs that will not be able to say, “I was wrong”. I’m not saying don’t use them but you better have some good layer of extra glass and distance protecting you. Also, be careful where you have these things near your kids.
Getting skin cell damage as a young child is the easiest way to develop skin cancer later on in life and skin cancer is extremely deadly if not caught early.
