Passive samplers for ambient ozone, formaldehyde and sulfur dioxide: Indoor, outdoor, and personal exposure applications
- DGA, Inc., Ventura, CA (United States)
Time-integrated measurements of air pollutants have many applications in the context of regulations pertaining to indoor air quality, outdoor (ambient) monitoring, and personal exposure assessment. For several years, the passive samplers developed at DGA have been applied to cost-effective measurements of parts per billion levels of ozone, formaldehyde and sulfur dioxide. Examples of applications will be described. These include (a) formaldehyde measurements in indoor settings including museums, public buildings and personal exposure; (b) ozone measurements indoor (museums, cultural heritage buildings) and outdoor (Class 1 Wilderness areas; air quality surveys in Europe, Canada and Latin America, long-term monitoring of ozone exposure in forests) and (c) surveys of ambient levels of sulfur dioxide in several eastern European countries.
