Exhaust emissions resulting from the motor vehicles have harmful and long lasting effects on both the human health and environment. Pollution in different floors of parking through the corridors and stairs will be transferred to other parts of the building and will create problems for the residents. The present study proposes a air quality monitoring system which measures and calculates the ppb value of ten gases including SO2, NO2, NOx, O3, CH4, H2, CO, NH3, Benzene, and Alcohol. Furthermore the particulate matter was measured through a particle counter instrument in parking different floors. The data collected has been compared. There is a direct relationship between the number of parked cars in the parking and the concentration of pollutants. Since Vehicle is the source of regulated pollutants majority of CO, NOx and HC and contributes to the formation of inhalable particulate matter emissions (PM10 and PM2.5) as well as being most source of carbon dioxide (CO2) (CETESB 2013). Therefore Concentration of pollutants varies with the number of vehicles.
