Standard 62.2. and indoor polllutant sources

The author asserts that to maintain a good indoor air quality, both ventilation and reduction of the pollutants sources are necessary. Standard 62.2 defines the minimum requirements about ventilation for an acceptable indoor air quality, but does not deal directly with the sources of pollutants. So the author gives an inventory of the main indoor air pollutants and how to cope with them. He maintains that the treatment of the pollutants at their source is very often the best way to keep a good indoor air quality.
