Re: stachybotrys - spore testing of air fails to show it - new paper shows one reason why

[Guest guest]

Is this why sometimes they test the air on an off business day

and find very low concentrations of spores?

I'm sure that study was done under completely controlled lab

environment insuring that the only disturbance came from the

controlled minute air flow. So what happens when it is on the inside

of the drywall and someone starts hammering nails to hang pictures,

Walking across a wooden floor causing vibrations within the walls,

stormy days with high winds that can at times rattle windows and walls.

I believe in lab testing, but sometimes the labs tests are too

sterile to show the actual results in real life environments. We've

been fighting the vaccine industry for quite some time for the same

reasons. The logic and studies all seem to be good, but the end

results in real life are not in our opinion the same. We have one boy

that is severely autistic due to an MMR vaccine, and at the age of 19

still wears diapers and still does not talk, and probably never will.

when wet and growing stachy has a sline covering it. bugs eat on the

slime and spores can be realeased but your not going to get good air

tests results when its growing as it only releases spores as it

dries. stachy spores are heavier too so even than it may not pick up

on air tests. I think to pick it up at all it needs to be dry. I

think it all settles down and then when dry it gets stired up by

air,traffic,ect. air tests were done in my victorian home by the

insurance company and they waited tell spring on a rainy day, they

knew. however my basement was dry and thats where it diltered down to

because of the way the home is vuild and air tests there picked up

much hugher amounts. it also ecplains why I got the most exposure in

winter when my steam heating system carried it back up with the hot

air.
