摘　　要：目的了解日照强度对室内空气质量的影响。方法通过对北京和广州市8间阳面与阴面房间内不同时间空气中化学污染物浓度和菌落数进行测定,研究日照强度对室内空气质量的影响。结果随着房间内日照强度的变化,阳面与阴面房间的污染物浓度与菌落数均有下降趋势,自9:00—16:00阳面房间化学污染物浓度平均下降率为80%,阴面为45%;阳面房间菌落数平均下降率为73%,阴面为60%。阳面房间内化学污染物浓度和菌落数下降幅度均高于阴面房间(P<0.05)。结论日照可以明显改善室内空气质量,日照强度的增强可加速室内化学污染物浓度的衰减以及细菌数量的减少。Objective To explore the effect of illumination intensity on indoor air quality. Methods The concentrations of chemical pollutants and the colony forming units （CFU） of the sunny or nightside rooms in the daytime were tested and the effect of illumination intensity on indoor air quality was studied. Results The concentrations of chemical pollutants and CFU decreased with illumination intensity, descending rate was 80% in sunnyside rooms and 45% in nightside rooms, CFU descending rate was 73% in sunnyside rooms and 60% in nightside rooms. Conclusion The indoor air quality can be improved obviously by sunshine, the decreasing rate of the concentrations of chemical pollutants and CFU may be accelerated by the increases with illumination intensity.
