Abstract A longitudinal study of personal, indoor, and outdoor exposures to PM(sub 2.5) and associated elements was carried out involving 37 residents of the Research Triangle Park area in North Carolina. Participant exposures were monitored for 7 consecutive days in each of four seasons. A main goal of the study was to estimate the contribution of outdoor PM(sub 2.5) to indoor concentrations and personal exposures. This contribution depends on the infiltration factor (the fraction of outdoor PM(sub 2.5) remaining airborne after penetrating indoors), which can be estimated using sulfur as a marker for particles of outdoor origin. The annual average infiltration factors ranged from 0.26 to 0.89, and depended strongly on air exchange rates. The outdoor contributions to personal exposure were then regressed longitudinally on outdoor concentrations measured at a central monitoring station, with a range of R(sup 2) values from 0.19 to 0.88. Variables significantly affecting indoor air PM(sub 2.5) concentrations included smoking and cooking, the number of persons in the household, burned food, use of a kitchen exhaust fan, and duration of candle use. These findings might have important implications for epidemiological studies.
