Indoor air quality affects the entire population, including residents of rural areas. Improving indoor air quality may require countrywide strategies, although the specific features of the urban and rural environments should be considered. The materials selected for building construction and furnishings, as well as the consumer products used indoors, should not adversely affect indoor air quality. Reducing the health risks related to indoor air pollution requires that occupants modify their lifestyles (such as in relation to tobacco smoking).
Agenda 21 recommends supporting research and developing programmes for applying prevention and control methods to reducing indoor air pollution, including economic incentives for the installation of appropriate technology.
