Indoor air is a dynamic mix of pollutants, with complex physical, chemical and microbiological properties
Strongly depending on the type of indoor environment
Factors affecting concentrations of indoor pollutants
Outdoor pollution Meteorological conditions
Indoor air sources Air mixing
Air cleaners
The way they are used
Building characteristics Ventilation rates
Indoor pollutant sinks
Some of them also relate to
energy
World Health Organization: Indoor Air Guidelines
1. Selected pollutants (2010):
2. Dampness and Mould (2009)
• Benzene • Carbon monoxide • Formaldehyde • Naphthalene • Nitrogen dioxide • PAHs • Radon • Trichloroethylene • Tetrachloroethylene
3. Household Fuel Combustion (2014)
