NO_2 concentrations in 30 multi family houses were measured by badge-type samplers and ques- tionnaire on operations of space heaters, cooking ranges and ventilation systems, number of tabacco smoking, activities for natural ventilation .and so on, were carried out during summer and winter seasons, simultaneously. The findings are as follows ; (1) On the basis of t-value two sided test, summer and winter NO_2 concentrations in houses using gas cooking ranges'were significantly higher than those using electric cooking ranges. (2) NO_2 concentrations in almost houses during summer were very low because habitants might intend to get natural ventilations for thermal comfort in summer. (3) Smoking in rooms scarcely contaminated indoor air quality, because smokers might be careful for ventilation during smoking, according to the social disapproval of passive smoking.
