Abstract
Indoor and outdoor aerosol sampling of two homes with wood-burning stoves was conducted at Waterbury, Vermont during February and March 1982. Altogether 201 indoor and 232 outdoor aerosol samples were collected using the continuous time sequence streaker filter samplers. The aerosol samples were analyzed by proton induced X-ray emission for the following elements: Al, Si, S, Cl, K, Ca, Ti, V, Mn, Fe, Ni, Zn, Pb, As, Se. and Br. We identified the major indoor and outdoor sources of the aerosols using factor analysis and studying characteristic source elemental ratios. Our results indicate that residential wood combustion, which is used in about half of the homes in Waterbury, is an important indoor source of particles and also significantly affects the chemical composition of outdoor aerosols.
