Re: Culturable mold indoor~association w/moisture-related pro...

[Guest guest]

I find this statement difficult to believe:

" Neither was there any association between the indoor spore concentration

and asthma/allergy among children. "

Typically, when there are the other contaminants that are present in WDB

that are also known to cause ill health effects like Dr.Thrasher note; there

is also an elevated mold spore count in the WDB.

As such, the following statement does not appear logical to me, based on

the above illogical statement in the writing:

" With these results, there is no reason for one-time air sampling of mold

colony-forming unit (CFU) in

indoor air of homes to identify risk factors for asthma/allergy in

children living in Scandinavian countries. "

Seems like a flawed hypothesis and thus flawed conclusion to me.

Or...maybe buildings are different in Scandinavia. WDBs have not always been

such

a dire cause of illness in the US.

It is not the spore count that they should be looking. They should have

included all of the contaminants in the building. The most likely association

would have been with the fine particulates, beta-glucans and the

endotoxins. Also, the Actinomycetes play an important role in respiratory

disease,

e.g. hypersensitivity pneumonias. They are also present in the indoor air.

Culturable mold in indoor air and its association with moisture-related

problems and asthma and allergy among Swedish children

" No association could be found between the spore concentration in indoor

air and asthma/allergy in the children.

Practical Implications

Mold spore exposure indoor have been suggested as a possible explanation

for airway problems such as asthma and allergy among people living in

buildings with moisture-related problems. However, this investigation

could not

find any associations between the spore concentrations in indoor air and

signs of dampness and moldy odor reported by parents or observed by

professional inspectors. Neither was there any association between the

indoor spore

concentration and asthma/allergy among children. With these results, there

is no reason for one-time air sampling of mold colony-forming unit (CFU)

in

indoor air of homes to identify risk factors for asthma/allergy in

children

living in Scandinavian countries. "

Sharon you are correct. I have emailed the authors for a copy of the

manuscript.

We must remember the following fact: Mold colonies (also bacteria colonies)

shed particulates ranging from less than one micron to the size of spores and

hyphae fragments (2 or greater microns). The fine particulates (less than 1

micron) are up to 500 time more concentrated than are the spores. The fine

particulates contain the endotoxins (toxic metabolites) as well as the

allergenic proteins (enzymes, hemolysins, among just a few). I individuals in

this forum want copies of the papers that describe the fine particles, email me

and I will forward them to you.

So even a high MERV filter for furnace or stand alone air cleaners, will not

catch these ultra fine particles and that is why one cannot depend on air

filters to solve contamination problem??

Hey barb, if filters worked nobody would have to leave their homes. I have had

every type of filter and never got relief from any of them, they are a waste of

money. They will help your lungs if they are damaged and you are in a mold-free

environment, but from mold, no- the toxin goes right through, and the

byproducts, and voc's.

I have found that no air filters/ionizers or even frequency-radionics work to

keep the house's air-toxins from making the occupant sick. Even opening all

windows and having a super-fan sucking fresh air, 24/7, at a very high rate will

not prevent the occupant from getting sick if the mold is badly established.

However, in some cases, a mold-grade 3M respirator, which happens to have about

a half an inch of carbon dust between two paper filters, does the job. However,

after a few days the filter will need to be replaced. That's not just a

manufacturer's recommendation so you'll buy more filters. A bit pricey for

daily use. Still, with the dispersants & hurricane season as it is... I'd

rather have some in hand than not.

Filtration is only as good as the pore size of the filters. Fine particulates

(<1 micron) can readily pass through filter, including HEPAs. The other problem

is that filter beds can become overloaded and down load with pressure shocks,

e.g. turning off and on the fans.

The toxins that Corondeen alludes to belong to two groups: endo and exo

metabolites. The endo metabolites are produced in the hyphae while the exo

metabolites are in the spores. If the fine particulates are permitted to get

through the filter, one is exposed to the endo metabolites. Also, the

mycotoxins are present in the fine particulates as demonstrated by Dr. Brasel

(Straus's laboratory) and Dr. Bloom (Sweden).
