The Effect of Traffic Density on Ambient SO2 and NO2 Concentration in Cipagalo Settlement Area, Bandung City, Indonesia
Abstract:
Air quality in an area can be affected by emissions from traffic activities. This research was directed to measure the level of ambient SO2 and NO2 concentration, and how much influence the traffic density had on ambient SO2 and NO2 concentrations in the Cipagalo area, Bandung City, Indonesia. Sampling was carried out at 2 sampling points which were considered to represent air conditions in the study area. The method used in this study is CSIRO passive diffusion. The traffic density calculation is carried out on Jalan Terusan Buah Batu, which passes in the study area. The results of this study show fluctuations in ambient SO2 and NO2 concentrations for 5 months of monitoring. In addition, the relationship of traffic density to the concentration of SO2 ambient in the linear regression equation was obtained with a correlation coefficient of 0.5357 for the range from morning to evening. While for the average measurement of each month for 5 months of research, the correlation coefficient was 0.4336. The relationship of traffic density to ambient NO2concentration in the linear regression equation obtained a correlation coefficient of 0.6885 for the morning to evening range. While for the average measurement of each month for 5 months of research, a very strong correlation coefficient was obtained which was equal to 0.9051.
