For example, an improperly adjusted gas stove can emit significantly more carbon monoxide than one that is properly adjusted. Radon can enter and collect inside homes and other buildings that are not built with radon-resistant techniques. However, buildings constructed with radon-resistant techniques can ensure lower radon levels, energy efficiency, and a safer home. Children are more susceptible to air pollution because they breathe a greater volume of air relative to their body weight. IAQ problems are not limited to homes and schools.
Many office buildings have significant air pollution sources.
Some of these buildings may be inadequately ventilated. For example, mechanical ventilation systems may not be designed or operated to provide adequate amounts of outdoor air.
