Short term, 99% of the spores stay attached.. thats why spore tests

are inaccurate with stachybotrys....

***99%***

And those toxins last a VERY long time. They have to go somewhere...

they don't just disappear.. Wall cavities are often channels for wind,

not completely sealed off, too.

Biomechanics of conidial dispersal in the toxic mold Stachybotrys chartarum.

Conidial dispersal in Stachybotrys chartarum in response to

low-velocity airflow was studied using a microflow apparatus. The

maximum rate of spore release occurred during the first 5 min of

airflow, followed by a dramatic reduction in dispersal that left more

than 99% of the conidia attached to their conidiophores.

Micromanipulation of undisturbed colonies showed that micronewton

(microN) forces were needed to dislodge spore clusters from their

supporting conidiophores. Calculations show that airspeeds that

normally prevail in the indoor environment disturb colonies with

forces that are 1000-fold lower, in the nanonewton (nN) range.

Low-velocity airflow does not, therefore, cause sufficient disturbance

to disperse a large proportion of the conidia of S. chartarum.
