Investigation of indoor/outdoor air pollutants at the shopping malls in Wuhan
Indoor air quality was investigated at eight shopping malls in Wuhan. Results demonstrate that there are different concentrations of CO
2and HCHO at different floors of a shopping mall. Even at different merchandise zones of a floor for the same mall, there are apparent variations in the concentrations of CO
2and HCHO. These findings should be considered in designing air-conditioning systems. The indoor/outdoor ratios of TSP, PM10, PM2.5, and PM1 are below unity for the three shopping malls when the air-conditioning systems are operating and they are near unity when the air-conditioning systems are not operating.
