Testing mold and indoor air quality

Recently, I was reading through the Healthy Indoors magazine and came arcross this great article by Jefferey C May.

Although I take many air and dust samples in my indoor air quality investigations, I’m going to play the Devil’s Advocate in this article and discuss what I believe are the weaknesses and pitfalls in many areas of mold testing.

First, air samples alone won’t identify the location of mold growth.

Sometimes the source can be something minor, such as a small patch of mold on a bathroom wall or ceiling.

The results of air testing for mold spores can be falsely reassuring. Let’s assume that a carpet in a finished basement playroom is contaminated with mold that is subsisting on the dust captured in the carpet fibers. If someone takes an air sample in the room without walking across the carpet, the air sample will seem fairly clean. But if the person happens to walk across the carpet first and then takes the air sample, the results will tell a very different story.  Read more

Recently, we have had a lot of enquiries about high formaldehyde readings in offices or public spaces. Commonly, little is known about Formaldehyde, what it is and how to deal with it.

What is Formaldehyde?

Formaldehyde is a colorless, flammable gas at room temperature and has a strong odor. Exposure to this may cause adverse health effects.

Where is it found?

It is found in many places, both naturally and synthetically. Primarily it is found within:

  • Resins used in the manufacture of composite wood products (i.e., hardwood plywood, particleboard and medium-density fiberboard)
  • Building materials and insulation
  • Household products such as glues, permanent press fabrics, paints and coatings, lacquers and finishes, and paper products
  • Preservatives used in some medicines, cosmetics and other consumer products such as dishwashing liquids and fabric softeners
  • Fertilizers and pesticides

It is a byproduct of combustion and certain other natural processes, and so is also found in:

  • Emissions from un-vented, fuel burning appliances, like gas stoves or kerosene space heaters.
  • Cigarette smoke.
