Toxic dust" on computers linked to diseasesBy Rachel Konrad, Associated Press
SAN FRANCISCO — "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.
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, are related to polychlorinated biphenyls (PCBs), toxins believed to damage brains of human fetuses.
Scientists have not directly correlated exposure to PBDEs with specific diseases. Researchers at University of California, Davis, and elsewhere are conducting studies questioning a link 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 — but they should write to politicians and ask for stronger protection against such chemicals.
"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, and they use lead, mercury and other toxins in the 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," said Dell spokesman Bryant Hilton. "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."
ive got one of the dell laptops with the "exploding battery" features.
This feature was not very popular with many customers who, unlike me, are not so self destructive.
I havent had mine go off yet but, theres always tomorrow.
Farmerman likes living dangerously?
Remember all the talk of women aborting due to sitting in front of computer monitors? They linked it to the radiation. Wonder if it was really the dust, or perhaps a dangerous combination of the two?
Farmerman, I heard a bit on the radio about a dell that went up in flames..... it was a funny bit.
Yeh, when I got the notice from Dell about the serial numbers on the "laptop bombs" I checked mine and my numbers were just over the recall numbers. Apparently they got a bad batch.
I dont do anything important on my laptop except some writing when Im away ferom home or office. sO, if it would go off, Id just lose the computer . Id love to be sitting in a cafe and have my computer flame up. Id tell everybody i got a new kind of virus that destroys your files by an explosion. that would get peoples attention
