Air pollutants caused by man were measured in a test chamber. Variables were number of persons and their activities and the rate of the air change. During test sessions of two hours the temperature, the relative humidity, the carbon-dioxide and intensity of odors were measured. There was a significant correlation between the odor intensities and the concentrations of carbon-dioxide independent of the number of persons and the air change rate.At air change rates of 12-15m**3 per person and per hour, the carbon-dioxide concentration was not higher then 0. 15%, and the odor intensity was evaluated only as a slight annoyance. Further experiments were performed with physical activity and smoking.
