Re: Pres of ACOEM responds to WSJ Article

MBobMean,
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
irrelevant.
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.
