Overview of measured
polutants
Prioritizing indoor polutants
Identification of potential health
outcome
Control strategies to reduce
health effects due to indoor air
quality
Research needs
We made an overview of relevant information of published literature
On sources of pollutants, prioritizing pollutants,
impact, potential health impact and control strategies
