Abstract: In this research work, West-Gaeke method was used to determine the ambient air SO2 concentration in Aba township area. The sampling was carried out from March to December 2013 covering the wet and dry seasons of that year. The mean concentrations over the year during dry and wet seasons were 0.180 ppm and 0.149 ppm respectively. The wet season concentration was 9.42 % lower than the dry season concentration due to rain attenuation. The highest concentration obtained was 0.259 ppm at Asa Nnentu Market (Latitude 05003’55, Longitude 007021’43) during the dry season while the lowest concentration was 0.082 ppm at Plot 204 Obohia Road (Latitude 05005’27, Longitude 007021’36) during the wet season. The values obtained in this work are higher than the limit of the Federal Environmental Protection Agency of Nigeria (FEPA) of 0.001-0.01 ppm for air quality standard which shows that the area is polluted by SO2.
