Why is indoor air pollution a concern?

Indoor air pollution is a concern in areas where energy efficiency improvements make houses relatively airtight, reducing ventilation and increasing pollutant levels. Indoor air quality issues can be subtle and do not always have obvious health consequences. Indoor air pollution is caused by a variety of factors in both rural and urban areas.

What air pollutants are present indoors?

Numerous air pollutants, including NOx, SO2, ozone (O3), CO, volatile and semi-volatile organic compounds (VOCs), PM, radon, and microorganisms, have been identified as being present indoors. Some of these pollutants (NOx, SO2, O3, and PM) can come from the outside and are present in both indoor and outdoor situations.

Is air pollution the Invisible Killer?

Present day pollutants are either colourless gases or particles so tiny that we can’t see them which is why modern air pollution has been called ‘the invisible killer’. When air pollution outdoors reaches unhealthy levels, the advice from experts is to avoid polluted areas and strenuous exercise, and if possible stay indoors.

Who is most at risk of outdoor air pollution?

Young children, older people and anyone with existing lung or heart conditions are more at risk from harmful health impacts. Where does outdoor air pollution come from? Outdoor air pollution can be caused by a range of nasties that come mostly from us burning fuel.
