Man contributes to indoor air pollution by the release of heat, humidity, carbon dioxide, particles, micro-organisms and body odours. The rise in temperature and the concentrations of the different pollutants depend on the number of persons in a room, the utilization of the room and the activities of the persons. Current parameters for the evaluation of man-made pollution in indoor air are carbon monoxide and odours. Experiments have been carried out in a test chamber under controlled conditions in order to determine the relations between carbon monoxide and odours, since these are two current parameters for the evaluation of man-made pollution in indoor air. In these experiments the variables were the number of persons in the room, the activity of the persons and the ventilation rate. For the measurement of odours a special method has been developed in which the undiluted air is tested by a test panel and compared with air containing two different pyridine concentrations. A significant relationship has been observed between the odour intensity and the carbon dioxide content of the air, and the correlation did not depend on the number of persons and the ventilation rate. At ventilation rates of 12 to 15 m3 per person and hour the carbon dioxide concentration was below 0.15% and the odour intensity was characterized as being only little annoying. Higher ventilation rates are necessary during physical activity and in rooms with tobacco smoke. The minimum ventilation rates as deduced from the laboratory experiments are compared to known standards.
人类通过释放热量、湿气、二氧化碳、颗粒物、微生物和体味，对室内空气污染有所“贡献”。温度的升高以及不同污染物的浓度取决于房间内的人数、房间的使用情况以及人员的活动。目前评估室内空气中人为污染的参数是一氧化碳和气味。为了确定一氧化碳和气味之间的关系，已在可控条件下的试验箱中开展实验，因为这两者是目前评估室内空气中人为污染的参数。在这些实验中，变量包括房间内的人数、人员的活动以及通风率。对于气味的测量，已开发出一种特殊方法，即由一个测试小组对未稀释的空气进行测试，并与含有两种不同吡啶浓度的空气作比较。已观察到气味强度与空气中二氧化碳含量之间存在显著关系，且这种相关性并不取决于人数和通风率。当通风率为每人每小时12至15立方米时，二氧化碳浓度低于0.15%，气味强度被描述为仅有轻微干扰性。在进行体育活动期间以及有烟草烟雾的房间中，需要更高的通风率。将从实验室实验得出的最低通风率与已知标准进行比较。
