Eight sampling locations in the study area were assessed for some air pollutants, level of noise pollution and some meteorological parameters. Portable handheld air monitor was used to measure air pollutants, a sound level meter and anemometer for level of noise and meteorological parameters respectively. Results showed that the highest concentrations of Nitrogen dioxide, Sulphur dioxide, Hydrogen Sulphide and Suspended particulate matter were recorded in indoor II while those for Carbon monoxide and Chloride were recorded in outdoor I. The outdoor locations recorded higher mean noise level and temperature (76.1 dB (A), 30.05°C) than the indoor locations (70.95 dB (A), 27.03°C). On the other hand, the indoor locations recorded higher mean relative humidity (62.8%) than the outdoor locations (48.25%). Significant difference (P<0.05) was observed only in the mean concentration of Chloride in the two environments. The mean concentrations of NO2, SO2, H2S, CO and Cl2 were above the permissible limit of Federal Environmental Protection Agency thus posing environmental risks. Appropriate vehicle emission management should be considered; air and noise pollution control agencies should intervene to reduce the risks associate with these pollutants and improve the air quality of the study area.
