The level of social and economic development is linked closely to determinants of indoor air pollution (IAP). There are major differences between developing and industrialized countries: IAP results from solid fuel use in the former, and from chemicals and new substances (e.g. formaldehyde, insecticides and phthalates) in the latter. However, secondhand tobacco smoke is a pollutant common to both settings. IAP also differs between rural and urban areas due to the different economies and lifestyles. For example, dust and organic particles are more common in agricultural areas and mites or fungal contaminants in closed, unventilated urban dwellings. The local climate conditions should also be taken into consideration, as they have an impact on architecture (building materials used, structure, room distribution and characteristics) and \u2013 particularly \u2013 on the ventilation of the dwelling. Children in urban areas spend most of their time indoors, which means that their primary exposure to air pollution may come from air inside homes and schools rather than outdoors. There are numerous situations in homes and schools which may result in possible exposure to contaminants, such as second-hand tobacco smoke, spraying of insecticides, accumulation of pollutants in carpets, poor quality air and others. Children may also be exposed where they play or at workplaces. The quality of children\u2019s environments can cause or prevent illness, disability and injury. Picture: WHO.
