Spore trap sampling

Spore trap sampling involves collecting airborne particles on a filter membrane or adhesive-coated slide by drawing air through or over the collection medium, respectively.  The collection medium is then analyzed by transmitted light microscopy, typically at 600–1000 × magnification.  A number of different collection devices may be used for spore […]

Direct microscopic examination of tape

Direct microscopy is considered the “gold standard” in environmental mycology for determining the existence of fungal growth on surfaces or materials. The direct observation of fungal spores, spore-bearing structures and mycelium provides an unequivocal marker of past or current growth. Direct microscopic examination of tape or bulk samples should first […]

How Toxic is Mold?

Really, How Toxic is Mold? Mycotoxins are naturally occurring substances produced by mold and are pathogenic to animals and humans. An estimated more than 300 mycotoxins are produced by some 350 species of fungi. The T-2 mycotoxin, which is classified as a trichothecene mycotoxin, is elaborated from the fusariam, aspergillus, […]

Thermal Imaging

Three Key Reasons You Should Consider Thermal Imaging Earlier this week, we discussed the problem of water stains and identifying the cause of the problem. One method to identify potential causes of water leaks and moisture intrusion is to have a professional conduct a thermal imaging inspection. Thermal Imaging, also […]
