5.2.3. Indoor air pollution

It refers to the physical, chemical, and biological characteristics of air in the indoor environment within a home, or an institution or commercial facility.

Indoor air pollution is a concern where energy efficiency improvements sometimes make houses relatively airtight, reducing ventilation and raising pollutant levels.

Indoor air problems can be subtle and do not always produce easily recognized impacts on health.


Different conditions are responsible for indoor air pollution in the rural areas and the urban areas.
