Volatile organic compounds in Tartu office buildings

The volatile organic compounds (VOCs) that are emitted by many materials an d activities are common indoor air pollutants. It is believed that VOCs mig ht contribute to many adverse health effects, but there is scant evidence t o support this. The difficulties involved in assessing the effects of VOCs involve both the chemistry of indoor air and the physiological responses in varying physical conditions. Inconsistent results of experimental studies and difficulties in performing longitudinal epidemiological studies have le d to the conclusion that only higher concentrations (in the range of 1-25mg /m(3)) of VOCs in indoor air should be considered to relate to higher healt h risks. This pilot study provides evidence that there is no such risk in E stonian offices.
