摘　　要： 对湖南省部分城市不同建筑类型室内的空气动力学当量直径小于等于10μm的可吸入悬浮颗粒物(PM10)室内外浓度进行了测试。分析测试结果表明,当室内无任何发生源和人的活动时,PM10的室内外浓度比(I/O)接近于0.85。在室人员的室内活动、吸烟、烹饪和空调的运行都会导致PM10室内外浓度比发生变化。在所有的室内发生源中,吸烟对PM10室内外浓度比(I/O)影响最大。在室内放置某些绿色植物,可降低PM10室内外浓度比,提高室内空气品质。 Indoor and outdoor concentrations of particulate less than 10 μm （PM10） were investigated in some cities in Hunan. The result is that, When in homes without any indoor source and human activity, the I/O ratio of PM10 was approximately 0.85, which were influenced by human activities, smoking, cooking and air conditioner operation. Of the indoor sources, smoking had the highest influence on I/O ratio. When haviag some green plants in rooms, PM10 I/O ratios could drop, and indoor air quality can be also improved.
