California Classes LED Component Gallium Arsenide a Carcinogen

Posted by timothy on from the tooth-fairy-is-a-cat-burglar dept.

Reader LM741N, pointing to a report released this month by California's Office of Environmental Health Hazard Assessment, writes "Gallium Arsenide has now been listed as a carcinogen. Given the increasing usage of gallium arsenide, the main constituent in LEDs, and their recent championing as more efficient light sources in recent news stories and Slashdot, there may be significant environmental concerns as related to their disposal. Morover, workers in industries using the substance may be at risk of cancer as well."

Sitting in your playstation or DVD player, it's not a concern to anybody but the workers soldering all day, and we have machines for that now.

  4. CFLs by OrangeTide · · Score: 3, Insightful

    CFLs cause cancer too. As technology uses more advanced chemistry (and the ability of medical technology to determent the carcinogenic properties of more materials) we can only find more dangers in the technology we use everyday.

    The important thing to do is to educate everyone that some materials need to be treated with care. And should not be ingested or inhaled. And should be disposed of immediately if they are damaged or broken. In addition disposable of all possibly toxic materials needs to handled specially. And if we're going to have CFLs, CRTs, LEDs, and other three letter acronyms in our households, then each and every one of us needs to be educated on what needs to be taken through a special technology disposable/recycling process.

    Here's a list of things people throw in the garbage that they should not have: rechargeable batteries, fluorescent lights, TV tubes(lead), car batteries(these are normally exchanged), used motor oil, appliances, electronics, ...

    ideally you should only be throwing out old food, soiled paper/cardboard, plastic. and recycling glass and non-toxic metals(steel, aluminum). you can try and recycle plastic too, but it is debatable.

    When you mix Californium and Governmentium, causing cancer is the only chemical reaction that is allowed to happen.

    The radioactive decay products of Californium include Liberelium and a heavy isotope of Governmentium called Bigovernmentium, which when combined are known to be toxic.

    Isn't one of the main advantages of LEDs the fact that you almost never need to replace them, which means (in theory) that they will rarely be discarded? And if they are rarely discarded, then isn't the disposal issue a moot point?

    I just wanted to point out that while many LED's are GaAs-based, most of the newer LED's that are starting to be used to replace things like traffic lights and light bulbs are GaN-based. No arsenic involved. Very non-toxic. In theory, your kid could eat several of the dies and be okay.

    Since when is it a bad thing to notify consumers that the products they're buying and using may pose a health risk?

    Since doing so excessively will trivialize the risk.

    Imagine if instead of severe thunderstorm and tornado warnings, the national weather service issued "wet weather" warnings any time it wasn't sunny. You couldn't tell the difference between a summer shower and a hurricane, and since summer showers are much more common you wouldn't realize today's warning meant 80mph winds until it was too late.

    If you are going to do warning labels for things that aren't a significant risk, you should at least put a "danger level" on them. We could have categories like for tornadoes:

    Instead of the Enhanced Fujita Scale, we'll have the Enhanced California Scale:

    EC0 - You might get cancer. But 40 million other Californians won't.
    EC1 - 1 in a million lifetime cancer risk from a single exposure
    EC2 - 1 in 10,000 lifetime cancer risk from a single exposure
    EC3 - 1 in 100 lifetime cancer risk from a single exposure
    EC4 - If you touch it and live another 50 years, you'll get cancer
    EC5 - You'll be lucky to be alive a year from now

If they didn't put those warnings on stuff, it probably woudn't be a problem!

    Why won't someone just make it simple? Wave an american flag in the direction of the perfect light bulb that has no real-world problems that I can pick up at walmart on my way to Ikea while driving in my hummer and forget all about cancer, global warming, and mercury forever.
