MEASUREMENTS OF INDOOR AIR QUALITY AND COMPARISON WITH AMBIENT AIR
This report contains the results of a survey carried out on 15 homes in Northern Italy to evaluate the occurrence of 35 selected volatile organic compounds and of total volatile organics in indoor and in ambient (outdoor) air. Measurements were carried out to determine also respirable suspended particulates and ventilation rates. The following results were obtained: Single pollutant concentrations were found almost always higher indoors than outdoors, frequently by an order of magnitude. Mean concentration of total volatile organics was about 3 mg/m**3 indoors, compared to about 0.4 mg/m**3 outdoors. The large variations from home to home observed for total volatile organic compounds in indoor air could not be correlated with the measured values of the minium ventilation rate. A more detailed analysis by GC-MS of 6 indoor samples led to the identification of a much larger number of compounds (more than 100 in two cases). The presence of some compounds could be positively associated with building materials and household products. Most identified compounds are of the solvent type.
