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

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)

Only qualitative!

• Reference levels of fungi/other bioaerosols? • Exposure - response relationship?
