ABSTRACT
Vehicles are main source producing NO2 and PM10. JIUJIUCHENG and JUSCO shopping malls with aim for reference are selected as tested location because their locations near the main roads of ZHU HAI. Total 5-days data of JIUZHOUCHENG and 1-day data on JUSCO shopping malls are collected. Low and high traffic are chosen after the traffic flow rate is counted, followed by measurements usingequipment provided by UIC’s laboratory. Tested points are selected and planned in order to maintain the data’s availability and reliability. The results indicate that heavier traffic causes higher content of NO2 and PM10, and there is similar tendency for both NO2 and PM10 data at high and low traffic periods for both ambient and indoor air.The ambient NO2 and PM10 content decrease as distance increase from road to gate of shopping mall. In addition, traffic does have impact on indoor air quality which is influenced by characteristics of different floors as well. However, for both ambient and indoor NO2 and PM10content, many factors that influence their content such as societal and environmental factors. Keywords: NO2, PM10, traffic
