VOCs, aldehydes, O3, NO2 and PM2.5 were measured in 37 office buildings in 2 seasons. The α-pinene and d-limonene concentrations were higher compared to those from past studies. The indoor concentrations in summer and winter varied significantly. An influence of floor level on indoor concentrations was observed for some pollutants. An evaluation of IAQ in terms of respiratory health effects was performed.
