Air Quality in the Vicinity of a Landfill Site in Rumuolumeni, Port Harcourt, Nigeria

Vincent Ezikornwor Weli, Obisesan Adekunle


The study investigated the air quality status in the vicinity of Rumuolumeni landfill with a view to determining the possible influence of weather parameters on the concentration of air pollutants from the landfill. Air quality parameters determined include nitrogen oxide (NO2), sulphur dioxide (SO2), methane (CH4), volatile organic compounds (VOC), ammonia (NH3), and hydrogen sulphide (H2S). Weather parameters examined include temperature, relative humidity, wind speed, wind direction. These data were collected with respect to distance from the center of the dumpsite into the residential area at 200m intervals for seven days using composite sampling technique. Pearson Correlation Statistics was used to test significant influence of distance from the dumpsite on the concentrations of pollutants. Results indicate that, pollutants considered except NO2 were higher at the dumpsite than the residential area. The mean value of SO2, CH4, VOC, NH3 and H2S at the dumpsite was 0.67 mg/m3, 0.06 mg/m3, 2.28 mg/m3, 0.12 mg/m3, and 0.19 mg/m3 respectively. Distance from the center of the dumpsite accounted for 41% (r2 of 0.4096; r of 0.64) and 29% (r2 of 0.2916; r -0.54) variation in the concentrations of NO2 and NH3 respectively at p=0.05. Results indicate that NO2, NH3 and H2S had significant correlations with temperature at 5% significant level with correlation coefficients (r) of 0.740, -0.766, and -0.699 respectively. In addition, NO2, NH3 and H2S were significantly correlated with relative humidity at 5% significant level with correlation coefficient (r) of -0.653, 0.727 and 0.646 respectively while SO2 and VOC were significantly correlated with wind speed at 5% significant level with correlation coefficient (r) of 0.591 and 0.739 respectively. The study recommends that measures to capture landfill gases and prevent their migration to the community are necessary.
