Abstract Share this page

Air pollutants generated from anthropogenic and natural sources are causing serious environmental concern. The ambient levels of carbon oxide (CO), methane (CH4) and hydrogen disulphide (H2S) in Nsukka were measured between April and June, 2011, at four locations with different characteristics in order to assess the level of pollution by the gases. While the levels of methane and hydrogen disulphide were below the detection limit of the Multi-gas monitor used, the highest level of 31 ppm was recorded for the day time concentration of Carbon oxide in Nsukka town. This value suggested that the level of C0, an asphyxiant, in Nsukka was above the World Health Organization guideline for 8-hour averaging time. The study was needed to obtain the baseline data of the level of pollution of the gases in the area and compare it with appropriate standards as part of the air pollution studies of the environment.
