Abstract

 Background and Objective: This is a cross-sectional descriptive study with the aim of Measure and determine the concentration of suspended particles: PM10 PM1; PM2. 5; And NO2 gases; SO2; CO; HC in open air six important passenger terminals and traffic jams in the metropolis of Tehran. Method: Using portable device MET ONE to measure suspended particles and the portable device Aeroqual to measure gases in the course of one year, from autumn 94 to summer 95. Samples were analyzed using software SPSS; EXEL. Findings: The results of this study showed that the highest concentration of suspended particles was PM1 with an average of 1. 20 micrograms per cubic meter; PM2. 5 with average of 6. 72 micrograms per cubic meter; PM10 with an average of 100. 23 micrograms per cubic meter; CO concentration with a mean concentration of 6. 95 ppm, NO2 with a mean concentration of 0. 05 ppm, SO2 with an average of 0. 05 ppm HC, with an average of 2. 56 ppm in winter. Discussion and Conclusion: The reasons for the increase in pollutants include: low temperature, no wind blowing, air reversal, terminal location, surrounding pollutants and type of fuel and technology used on buses. Using the results of this research, we can devise appropriate methods for controlling and reducing air pollutants with the aim of improving the system in these sites.
