The indoor concentrations of nitrogen dioxide were measured with small passive samplers in five houses. The following results were obtained. 1) When the kerosene-fired heater (unvented-radiant type) was used for 16.5 hours in the living room, the 24-hour average of NO_2 concentrations in this room amounted to 73.0 ppb. It was three times the level 21.3 ppb of the day without the heater. 2) During the period without heating, the indoor levels of NO_2 concentration were 20-40% lower compared to the outdoor levels. The cooking gas burner and gas water heater did not cause much effect on the level of NO_2 when the ventilation fan was used at the same time. 3) By cigaret smoking, the NO_2 levels in the room hardly increased. It was suggested that NO produced by smoking was hardly oxidized into NO_2 in the room.
