Abstract

• Rapid and unsystematic industrialization has become a major environmental concern for both developed and developing countries. Long-term and short-term effects on human health have been observed due to poor quality. In this study, a number of pollutants such as total suspended particulate matter (TSPM), particulate matter(PM-10), SO2 and NO2 affecting ambient air quality were measured for specified location in Ahlone Township, Yangon City. During study period from November 2015 to October 2017, variations of the pollutants have been monitored weekly, monthly and seasonally. On the basis of the monthly average, the statistical distribution parameters such as average, standard deviation (SD), minimum (Min) and maximum (Max) values for each of the pollutants were obtained. The average concentrations of TSPM, PM-10, SO2 (24 h) and NO2 (24 h) observed during the period of (2015-2017) were found to be 73.24 ± 43.44 μg m-3, 38.43 ± 27.27 μg m-3, 0.109 ± 0.271 μg m-3, 6.38 ± 8.46 μg m-3 and 19.31 ± 33.41 μg m-3 respectively. All pollutants were observed to be high in concentration during summer as compared to winter and rainy, due to slow dispersion and dilution of pollutants. The results of this study identified the degree of air pollution in Ahlone Township, Yangon City. The data obtained will be statistically treated using SPSS (Statistical Package for the Social Science) software version 22.
