Re: Airborne Fungal Concentrations in buildings and outdoors in the United States

[Guest guest]

I would not trust anything that comes out of PathCon Labs. For those

who do not know, the CDC, Emory University and PathCon Labs all

basically have interchanging employees and they do not wavier from

one another. No matter what the science may say or reveal. So this

is where most of the spin comes from in the Southeast.

And for the record I have spoken to all three and the answers were

like listening to a recording.

Bill,

There has been extensive research done by Universities and

environmental groups. It would be difficult at this time to check my

information, but a good start with some of the most up to date

information, I would check into : mold-help.org,

chronicneurotoxins.com, mycotoxicosis.com, and there are other links

listed in files from the main page of this group in the links

folder. But I would definately disregard this last research article

you mentioned. If you are needing further help, email me.

I haven't seen anything like that, Bill. The problems with the study are that A)

levels of mold spores change constantly, so the study is now outdated any way

you slice it; The level of ignorance that proclaims " more mold outside than

inside " does not in any way account for concentrations of mold as it occurs

indoors and is delivered to its victims; C) This study, like most others, also

seems entirely ignorant of what mycotoxins can really do to the human body,

i.e., they only want to reference allergic reactions and MAYBE respiratory

illness; D) the study seems geared toward trying to establish what " acceptabel

levels of indoor mold might be - which is nothing more and nothing less than a

game designed to disclaim responsibility for making people sick; E) KC is right.

I didn't check the authors' credentials myself on this one, but you have to

always be wary of possible cross-contamination between Emory University, CDC,

and private industry (especially those local to CDC and

Emory, which PathCon definitely is). The Old Boy network is fully in play

there.

At best, the study came up with a rough guesstimate of some correlation between

regional and seasonal rise and fall in spore counts. But even then...did I skip

over that part, or did they not bother to fully speciate those cultures?
