Interesthing thing on toxic dust in computers
'Toxic Dust' on Computers Tied to Disease
By RACHEL KONRAD SAN FRANCISCO (AP) - ``Toxic dust'' found on computer processors and monitors contains chemicals linked to reproductive and neurological disorders, according to a new study by several environmental groups. The survey, released Thursday by Silicon Valley Toxics Coalition, Computer TakeBack Campaign and Clean Production Action, is among the first to identify brominated flame retardants on the surfaces of common devices in homes and offices. Electronics companies began using polybrominated diphenyl (PBDEs) and other flame retardants in the 1970s, arguing that the toxins prevent fires and cannot escape from plastic casings. ``This will be a great surprise to everyone who uses a computer,'' said Ted Smith, director of the Toxics Coalition. ``The chemical industry is subjecting us all to what amounts to chemical trespass by putting these substances into use in commerce. They continue to use their chemicals in ways that are affecting humans and other species.'' Researchers collected samples of dust from dozens of computers in eight states, including university computer labs in New York, Michigan and Texas, legislative offices in California, and an interactive computer display at a children's museum in Maine. They tested for three types of brominated flame retardants suspected to be hazardous. The most toxic piece of equipment discovered by the researchers was a new flat-screen monitor in a university in New York, implying that newer equipment isn't necessarily cleaner. Penta- and octa-brominated diphenyl will be taken off the market by the end of the year. Environmental groups are demanding legislation that would ban deca-brominated diphenyl, too. PBDEs, which have caused neurological damage in laboratory rats in numerous studies, are related to polychlorinated biphenyls (PCBs). PCBs have been used in fire extinguishers, fluorescent lights and liquid insulators since the 1920s. PCBs were outlawed in the 1970s, but the toxins don't erode and still persist in the environment. The Agency for Toxic Substances and Disease Registry, part of the U.S. Department of Health and Human Services, and several other organizations have confirmed that PCBs damage brains of human fetuses. Scientists have not directly correlated exposure to PBDEs with specific diseases or developmental impairment. Researchers at University of California, Davis, and elsewhere are studying possible links between brominated flame retardants and autism, but results are years away. Independent researchers who reviewed the new study say consumers shouldn't throw out their computers, and they needn't wear special gloves or minimize exposure to computer monitors. There's no known way to remove dust-born PBDEs, so special wipes or sprays wouldn't reduce chemical exposure. ``The levels in the dust are enough to raise a red flag, but not enough to create a crisis,'' said Dr. Gina Solomon, senior scientist at the Natural Resources Defense Council and assistant professor of medicine at University of California, San Francisco. ``I have an old computer monitor in front of me now, and I'm not about to throw it away. But when I get a new one, it darn well will be free of these chemicals.'' The electronics industry has been reducing or eliminating some brominated flame retardants since the late 1990s, when European countries began prohibiting the sale of products that contain the chemicals. Dell Inc. and many other computer makers continue using a flame retardant related to PBDEs on circuit boards. They use lead, mercury and other toxins in central processing units and monitors. But Dell, along with Apple Computer Inc. and others, stopped using PBDEs in 2002. ``People can be very confident about their new computer purchase,'' Dell spokesman Bryant Hilton said. ``We've worked a lot with suppliers, and we require audits and material data sheets on all our products. It's an important topic to be aware of, and brominated flame retardants are something we've been very focused on and will continue to be focused on.'' |

First you say they are, then you say they stopped; which is it? Yeah that part is confusing. I think they mean "related to" so they are continuing to use something like PBDEs but not PBDEs ? I dont know. However cycnics have pointed out that theres lots of toxic stuff in PCs and in its production. You know when people used to crow about how we were moving from dirty basic manufacturing industries to cleaner high tech industries. That article really makes me feel great about the 3 old systems I was working on that were covered in sooty dust particles that I cleaned off in my living room. I was gagging all night on the particles. I hope they werent mixed with toxic crud. |

That's ok, I've been breathing a bit of it lately [grin]

It was spread everywhere like the CNN site : http://www.cnn.com/2004/TECH/ptech/06/03/toxic.dust.ap/ The credibility though rests on how credible this group is "Toxics Coalition" blah blah . Ive never heard of it before. Its possible someone else could come out later and say the danger is grossly overstated. I recall flame retardants on foam rubber, plastics were mentioned in numerous articles as a cancer danger and not breath the crumbling dust like particles of old foam rubber etc. Dont know if its the same stuff. In fact my creep out story of the year was on teflon. One of those news shows had a thing on teflon. A long story about how teflon is now used everywhere to repel dirt as well as non-stick pans. They put it on rugs , clothing , furniture etc. They also said they found teflon fumes coming from pans so they recommended not heating up pans with nothing in them . Of course not too many people would do stuff like that except by accident - all the water boils out or you are warming it up and forget about it. They also said some researchers found surprisingly high levels of teflon in people's bloodstream. And third , they claimed it may be toxic. The scare story is that the fumes from heated pans will kill some birds very quickly. I think thats how the story goes. Anyway ---- Id never heard this. The story overall had a cautious tone with a scientist/spokesman from the firm that makes Teflon saying further studies have to be done but they are fairly sure its not a big danger now. I did a search and found as you usually do - numerous scare sites "PANS OF DEATH !!!!" "FRYING PANS OF HORROR !!!!" They make is seem like we were duped by the usual evildoers "Corporations" into ingesting pure poison. They cite the usual thing about birds dying from telfon fumes from pans. Not sure if its serious or not but its a concern because I use to get into fights with my mother ages ago when she used to keep using old frying pans that had curling chips of teflon on the inside which she would say was a waste to throwaway. Even I know know that ingesting big chunks of some metallic substance is not good news. She only reacts when a scare story goes on the news, then she gets hysterical about it but always seemed to lack common sense. |
