>>'Toxic Dust' on Computers Tied to Disease
>>By RACHEL KONRAD, AP
>>
>>SAN FRANCISCO (June 3) - "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.
>>
>>AP
>>
>>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."
