QUANTIFICATION OF INDOOR/OUTDOOR AIR POLLUTANTS AT THE SHOPPING MALLS IN SHANGHAI
Measurement was performed at three shopping malls in Shanghai. Parameters measured include carbon monoxide (CO), carbon dioxide (CO2), formaldehyde (HCHO), and particulate matter (PM10, PM2.5, PM1). Results demonstrate that there were different concentrations of CO2 and HCHO at different floors of a shopping mall. At two shopping malls without indoor sources except for consumers and where occupant density is under middle level, the indoor concentrations of PM10、PM2.5、PM1 are lower than outdoor concentrations. In one shopping mall with indoor sources like cooking and where occupant density is under high level, the indoor concentrations of PM10、PM2.5、PM1 are higher than outdoor concentrations, and the indoor/outdoor (I/O) ratios above unity. It implies that indoor pollution from particulate matter at this shopping mall is much serious than that of outdoors and the indoor source has much contribution to the concentration of indoor particulate matter. These questions should be considered in design of air conditioning system.
