INDOOR AIR POLLUTION DUE TO EMISSIONS FROM WOOD-BURNING STOVES.

Four wood-burning stoves, three airtight and one non-airtight, were operated in a single-floor 236-m**3 residence and tested for indoor pollutant emissions. Results showed the airtight stoves emitted minor amounts of carbon monoxide and respirable suspended particles during door-opening operations, while the nonairtight stove continuously injected pollutants indoors under certain operating conditions. During airtight stove operation, carbon monoxide levels reached a maximum of 4 ppm, while average total suspended particulate levels ranged from 24 to 71 mu g/m**3. During 'normal' nonairtight stove operation, carbon monoxide levels reached a maximum of 8 ppm, while total suspended particulate levels ranged from 30 to 650 mu g/m**3. Outdoor carbon monoxide levels were 1. 1 ppm or less, and outdoor particulate levels ranged from 7 to 31 mu g/m**3. Five polycyclic aromatic hydrocarbons, including benzo left bracket a right bracket pyrene, were measured in the collected particulate samples, and the results are reported. Source strengths for carbon monoxide, total suspended particles, and five polycyclic aromatic hydrocarbons are reported.
