Molds (fungi) are part of the natural environment, found virtually everywhere outdoors.  The spores enter through windows and doors, on clothing, hair, and fur. When conditions deteriorate because of excess moisture, leaks, floods, spores can multiply and become a problem causing odour and visible damage to building materials.

Exposures are unavoidable, but in most cases harmless.  Don’t be mislead by alarmists claiming that mold is “toxic”. This is very rare. Mold infections are relatively uncommon.  Allergic effects of mold such as hayfever (rhinitis), allergy induced asthma, hypersensitivity pneumonitis, aspergillosis/mycosis, and sinus inflammation are the real issues.

Testing commonly reveals spores of Cladosporium, Ascomycetes (mold cousins), and Basidiomycetes outdoors. Common “indoor” molds include Aspergillus, Penicillium, and Cladosporium.

OSHTECH is registered as an NAB (National Allergy Bureau) testing facility, the only one in Canada. Throughout the year, except in winter, we conduct ambient daily sampling for accurate mold and pollen counts. To view current mold & pollen counts for London, ON  click on the NAB logo to the right.
