California Statement on Building Dampness, Mold, and Health
Do people, especially children, get sick in damp buildings? Is it because of the mold? Or is it the bacteria, insects and rodents attracted to the moisture causing the problems? Or is it a combination of these exposures having a negative synergistic effect? Although the answers to these questions are not well understood, the California […]
Dampness, Dust Mites and Mold
When travelling this week, I was reading the latest Indoor Air journal and there were two interesting articles that both studied the relationship between mold and dust mites. The first article was titled, A comparison of the allergic responses induced by Penicillium chrysogenum and house dust mite extracts in a mouse model _1. Lab mice […]
Federal Agency’s Checklist for Mold
The National Institute for Occupational Safety and Health (NIOSH) is conducting a pilot study to establish a standardized checklist for a mold and moisture inspection. This checklist is more designed for building owners and operators rather than for experienced consultants. First let me explain the background of the checklist and how it works, then I’ll […]
Mold: More than a Number
You may take air samples when trying to identify a hidden mold problem. The total number of spores in the complaint area should be compared to indoor and outdoor controls, or more accurately, “references”. For example, if you find 10,000 spores per cubic meter in the complaint area, and only 1,000 in the reference samples, […]
Increased mold levels coming?
Can increased levels of atmospheric carbon dioxide (CO2) have an effect on mold spore levels? A new study suggests that increased CO2 will, in fact, lead to a greater number of mold spores outdoors with a resulting effect on allergies. As CO2 levels rise, can we expect to see more allergies to mold? The article […]
