Evaluation of ambient air quality in selected high, medium and low density areas of Kaduna metropolis, Nigeria
Author(s): Henry MU and Egila JN
Abstract: Ambient air around Kaduna metropolis was monitored using continuous analyzers for SO2 NO2, CO2, CO, CH4 and PM during wet and dry seasons presented using four urban locations and a control for one year from February 2013 to December 2013. The sites are: Industrial area/medium traffic volume, High population density/ high traffic volume, Medium population/ high traffic volume, Low population/ medium traffic, and Low population/ low traffic volume, as the control. Correlations among pollutants concentration and linear regression established. Air pollution index calculated. The overall concentration levels for SO2, NO2 CO2, CO, CH4 and PM were 0.34±0.08, 0.32±0.10, 2.70±0.29, 0.32±0.06, 0.29±0.10 and 39.91±3.33µg/m3 respectively. However the values were within the limit of NAAQS except for NO2 which recorded 0.32ppm as against 0.1ppm. Strong positive significant correlations were established among pollutant concentrations (p≤0.05). API calculated was moderate and showed that none or few may likely to be affected.
