Indoor and outdoor concentrations of PM(2.5) were measured for 24-hours during heating and non-heating seasons in a rural, solid fuel burning, Native American community. Household building characteristics were collected during the initial home sampling visit using technician walkthrough questionnaires, and behavioral factors were collected through questionnaires by interviewers. To identify seasonal behavioral factors and household characteristics associated with indoor PM(2.5), data were analyzed separately by heating and non-heating seasons using multivariable regression. Concentrations of PM(2.5) were significantly higher during the heating season (Indoor: 36.2 μg/m(3); Outdoor: 22.1 μg/m(3)) compared to the non-heating season (Indoor: 14.6 μg/m(3); Outdoor: 9.3 μg/m(3)). Heating season indoor PM(2.5) was strongly associated with heating fuel type, housing type, indoor pests, use of a climate control unit, number of interior doors and indoor relative humidity. During the non-heating season, different behavioral and household characteristics were associated with indoor PM(2.5) concentrations (indoor smoking and/or burning incense, opening doors and windows, area of surrounding environment, building size and height, and outdoor PM(2.5)). Homes heated with coal and/or wood, or a combination of coal and/or wood with electricity and/or natural gas had elevated indoor PM(2.5) concentrations that exceeded both the EPA ambient standard (35 μg/m(3)) and the WHO guideline (25 μg/m(3)). |
