    Re: Pres of ACOEM responds to WSJ Article

    Posted by Sharon on 1/25/07


    I don't know anything about the NSC. However, the document you
    cite is authored by the principals of Veritox:

    Coreen A. Robbins, Ph.D., CIH, Lonie J. Swenson,CIH, William
    T.Geer, CIH, and Bruce J. Kelman, Ph.D., DABT

    This is the same litigation defense support corp that authored
    the ACOEM Mold Statement.

    NO ONE besides this corp has professed to be able to establish
    human threshold/dose indicative of human mycotoxin exposure
    within a water damaged building by using extrapolations founded
    upon data from rodent studies. Their findings in this matter
    have been replicated by NO ONE ELSE.

    You can't do. Among other reasons, with a primary reason being
    is that when humans are exposed to mycotoxins within a water
    damaged building, the toxins enter the body via all three
    routes of exposure simultaneously. So to do an inhalation study
    of mice and attempt to corrolate that to the human situation is

    Also, when humans are exposed to mycotoxins within water
    damaged buildings, they are exposed to several (along with
    other microbial contaminants) simultaneously. Therefore the
    threshold/dose would change for each mycotoxin because the
    other variables involved would change the level of mycotoxins
    that would cause ill health. Not well worded, but the data
    would need to be lowered for each toxin as there is alot going
    on within the body and the building when water damage/mold is
    involved that can't be studied simply by instilling one type of
    mycotoxin into the lungs of mice/rats.

    And different molds have different weights. You can't study
    Stachy and conclude aspergillus. So to use the genertic
    term "mycotoxin" does not apply equally for all mycotoxins. The
    dose relevant for humans to become ill from mycotoxins/molds
    within a water damaged building is an indeterminable number.

    Rodent studies are very valuable though. While they can't
    establish dose, they do help to understand what the human
    symptoms are when mycotoxins are within the body.
