Introduction

In the last several years, we have become aware of a new type of pollution (actually, it has existed for a long time).  Sick building syndrome, radon, second hand smoke, asbestos, and lead in paint are all terms that have become common.  We are now recognizing that indoor pollution is a major problem.

Scientific evidence has indicated that the air within homes and other buildings can be more seriously polluted than the outdoor air in even the largest and most industrialized cities.  Interestingly, people spend approximately 90 percent of their time indoors.  In short, we may be spending most of our time in the more severely polluted atmosphere.

Indoor air pollution includes: environmental tobacco smoke; radon; combustion products; household products, household chemicals; and biological contaminants such as bacteria, molds, mildew, viruses, animal dander and cat saliva, house dust mites, cockroaches, and pollen.  For many people, the risks to health may be greater due to exposure to air pollution indoors than outdoors.

Are you, your family, or your workers exposed to indoor air pollution?  Of course.  But how much?

Many indoor air contaminants are naturally occurring.  Furthermore, we have increased the likelihood of indoor air contaminants accumulating by weatherizing our homes and offices to save energy.  Energy conservation is a good idea but it contributes to indoor air quality problems if there is not sufficient ventilation.

Do you think you may have an indoor air quality problem in your home, office, apartment, or other building?  An Indoor Air Quality investigation can help you determine if there is a problem that should be addressed.  

An IAQ investigation should be conducted by an experienced professional.  The investigators inspect the design and operation of the ventilation system and other building features.  When appropriate, the investigators may take measurements of pollutants such as carbon dioxide, carbon monoxide, and microbial contaminants (bacteria, fungi, etc.).  Once a problem is identified, the consultant can make recommendations to eliminate or remediate the problem.

What is IAQ  

Indoor air quality (IAQ) is a term referring to the air quality within and around buildings and structures, especially as it relates to the health and comfort of building occupants.

IAQ can be affected by Microbial contaminants (mold and bacteria), gases (including carbon monoxide, radon, and volatile organic compounds), particulates, or any mass or energy stressor that can induce adverse health conditions.  Indoor air is becoming an increasingly more concerning health hazard than outdoor air.  Using ventilation to dilute contaminants, filtration, and source control are the primary methods for improving indoor air quality in most buildings.

Determination of IAQ involves the collection of air samples, monitoring human exposure to pollutants, collection of samples on building surfaces, and computer modelling of air flow inside buildings.
