    Re: Chinese Drywall

    Posted by Concerned Citizen on 7/03/09

    Please allow me to clear up your misinformation. The levels of
    carbon disulfide, carbonyl sulfide and dimethyl sulfide
    collected through both vacuum canister are direct reading
    methods are below detectible limits of 2.5 ppb in over 95% of
    houses sampled to date. This data is available both through
    the Florida Department of Health and various environmental
    companies retained by the State and private concerns.

    If you knew anything about gas sampling, you would understand
    the issues surrounding the collection of hydrogen sulfide.
    Regardless of your ignorance, the levels of exposure to
    hydrogen sulfide are below detectable limits.

    Unless one is eating large quantities of Chinese drywall, the
    level of toxicity is below any and all OSHA and NIOSH
    standards and all the test data collected to date proves this
    time and time again. Seems the only people attempting to push
    the "Toxic Chinese Drywall" agenda are those who are
    attempting to profiteer from ignorance.

    If anyone wants the facts, please call the Florida Department
    of Health at 850 -245-4147 or Jack Bowles, EPA Director of
    State and Local Relations, at 202 564-3657.

    A fool and his money are soon departed.
