Indoor Air VOCs


Indoor air investigations can be challenging.  There are many aspects to indoor air quality, including volatile organic compounds (VOCs), inorganic compounds, particulates, allergens, comfort factors, etc.  One of the most difficult areas to look at is the VOCs, which are organic chemicals (containing primarily carbon and hydrogen) that vaporize easily at room temperature.  There are thousands of different VOCs in indoor air from hundreds of sources, making both source identification and remediation plans challenging.

Most people do not notice an indoor air quality problem unless they smell something unpleasant or feel ill but many VOCs have no noticeable characteristics, leading to poor air quality situations without any perceptible signs.

In developing an action plan for resolving VOC issues, it’s not sufficient simply to know which chemicals are present.  Understanding the sources as well as how the VOCs will react to changing conditions is crucial to improving air quality.

Because air quality is such a complex issue it is important to have a clear goal in mind when preparing a sampling strategy.  Here are a few key questions to ask yourself.

  • What’s the problem or purpose?  Odor, physical symptoms, real estate transaction, monitoring, simple curiosity?
  • Is the problem present all the time or is it specific to a particular location/time/activity?
  • Have any new products, activities, or environmental conditions been introduced recently?
  • Is the effect limited to one person or is everyone affected?
  • Do you need an overview of the VOCs or more detailed chemical information?

Prism offers a wide range of sampling and analysis options to address your indoor air concerns.
