摘要：The concentrations of dust, benzo [α] pyrene (B [α] P) and nitrogen dioxide (NO2) were determined in the air inside and outside of private houses in Nagoya City. Thirty-eight private houses were investigated in summer and winter during 1985-88. The mean indoor dust, B [α] P and NO2 concentrations were 0.05±0.05 mg/m3, 2.03±2.11 ng/m3 and 18±9 ppb in summer, and 0.09±0.05 mg/m3, 3.59±4.68ng/m3 and 38±24 ppb in winter, respectively. A significant correlation was obtained between indoor and outdoor B [a] P concentrations both in summer and winter, but the indoor B [a] P concentration was higher in the houses with oil stoves (reflex type) than in those without oil stoves (reflex type). The combustion between old and brand-new oil stoves was examined experimentally.
