It is now recognized that non-industrial indoor environments can contribute significantly to human exposure to airborne pollutants. This is particularly true in Canada, with its long cold winters and hot summers, which results in considerable amounts of time being spent in climate-controlled buildings. The working group was set up in October 1980 to consider a definition of acceptable air quality, the need for objective and/or maximum acceptable concentrations for specified substances and a specification of ventilation rates, or recirculation criteria in domestic premises. This report presents guidelines and recommendations for substances with non-carcinogenic and carcinogenic effects, and for substances with recommendations for controlling exposure. A description of the derivation of the guidelines is also included. Recommendations were not developed for radon because of the specialized knowledge required to develop guidelines.
