What do existing measurement and model results reveal about indoor air chemistry?

Key objective:

To identify species to measure indoors based on existing indoor results.
In order to achieve this objective, the following tasks will be carried out through reviews of existing literature and current projects, with results presented at workshop 2 in month 12:
1. Identify key indoor gas- and particle-phase species based on existing measurements and model results. This will include measurements in buildings, but also relevant measurements from chamber or laboratory studies (e.g. kinetic experiments, toxicological assessments).
2. Provide source apportionment of indoor pollutants, both in the gas- and particulate-phases (e.g. indoor vs outdoor; human vs natural, primary vs secondary).
3. Identify parameters that cause major uncertainties in indoor air models.
4. Provide a list of recommendations for WGs3-6.
