Abstract

BACKGROUND: Urbanization, energy consumption, intensification of road traffic and rapid population growth pose significant challenges to ambient air quality. Therefore, regular monitoring of current air quality is essential.

OBJECTIVES: The study investigated the concentration of sulfur dioxide (SO

METHODS: Air samples were collected into specific absorbing solutions twice daily in the morning and afternoon for four weeks. The resulting solutions were analyzed following specific colorimetric techniques according to standard methods of analysis.

RESULTS: Average concentrations varied among the sampling areas. All were above background levels obtained at the control site. Overall concentrations were found to be 30±19 μg/m

CONCLUSIONS: In spite of the short duration of sampling, the data can guide future long term monitoring of air quality in Nigeria. The level of SO
