『Abstract
Measurements of indoor and outdoor aerosol concentrations and
their gaseous precursors (O3, NO and NO2) as well as volatile organic compounds (VOCs)
concentrations were performed at two houses in the Oslo metropolitan
area. The variability of the concentration of gaseous compounds
was studied in respect to their sources in the indoor and outdoor
environments. Domestic heating during the winter and photochemical
production during the summer were the main sources for outdoor
NOx and O3. In the indoor
environment infiltration of outdoor air, candle burning, smoking
and indoor chemical reactions were the main sources affecting
their concentrations. The concentrations of VOCs outdoors were
enhanced during the summer due to biogenic emissions whereas in
the indoor environment their values were affected mostly by emissions
from materials used during the recent refurbishing of the hocuses
(＞0.4 mg/m3).
