Florida Mold Licensing

I’m teaching an IAQ and mold course in Florida this week, where legislation was recently passed to license mold professionals. The state law requires both assessors (inspectors) and remediation contractors to obtain a state license. The precise requirements have been slow to be released, with many questions still remaining. Here are some of the facts we do know:


Interpreting Mold Spore Counts from EAA, Inc.

Mold Spores

Taking air samples for mold spores is easy. Knowing how to interpret the laboratory results is another matter.

There is no one level of mold that can distinguish a clean and moldy building. Outdoor spore types and concentrations have an important influence on the indoors. Unfortunately, the outdoor types and concentrations of mold vary quite widely over time and space.  In other words, some climates during certain times of year will have extremely high concentrations, and other climates at other times of year will have extremely low levels.  We can compare the indoors to outdoors, but realize that the outdoor concentration is a moving target!

IAQ Website of the Month

6,000+ page website dedicated to… Aspergillus

Each month we publish a newsletter titled IAQ Website of the Month. The excerpt below was originally published in the June 2010 newsletter.

Although Stachybotrys is the genus of mold that captures the headlines, you won’t find a six-thousand-page website dedicated to it.  That distinction belongs to another mold, Aspergillus.

Aspergillus, is a common genus of mold known for its practical uses (soy sauce, soft drinks) and serious effects on human health (aspergillosis).

This month’s featured website is a massive hub for all information related to Aspergillus.  The “Aspergillus Website” is owned and funded in part by the Fungal Research Trust, based in Manchester, UK.

Here are five sections of the website that I find of interest:
