| Abatement of Stachybotrys Contaminated Wall |
| "Sampling air by impacting airborne material against a sticky surface "Spore Trap" provides a relatively simple and cost-effective was to assess spore levels. This method does not discriminate between viable (alive) and non-viable (dead or dormant) spores, and spores can be counted so that estimates can be made of number of spores per cubic meter of air. Passive sampling methods such as agar plates are not good indicators of ambient mold spore, because not all mold spores grow well, or at all, in culture including many basidiospores, Stachybotrys chartarum (atra), rust, smuts, some xerophilic and those spores that grow better in low water availability, specifically, Penicillium and Aspergillus, as well as those spores that are no longer viable, but my still be allergenic." - Trevor Lumley, PhD Microbiologist, August 2003, Study of Toxic Mold |
