Abstract
ABSTRACT

The level of gaseous pollutants CO, NO2, NH3, and H2S at four strategic places CAS campus (site A), PRESCO campus (site B), ISHIEKE campus (site C), and PERMSITE campus (site D) in Ebonyi State University, Abakaliki business centers were determined using a hand-held Portable gas monitor (gas man model CO1925 6H, NO2 19835H, NH3 19736H, and H2S1975 2H) for a period of two seasons (dry and rainy season). The ascending order of magnitude of the concentration of the gaseous pollutants in the dry season was NH3 ˂ NO2 ˂ CO. The same trend was also recorded in the rainy season while H2S was not detected in both seasons. The range of NH3, NO2, and CO in the dry season was 0.24±0.00 site B to 0.53±0.05 site D, 0.38±0.08 site B to 0.82±0.25 site D, and 0.98±0.28 site C to 1.52±0.51 site D respectively. The result of NH3 obtained during the rainy season ranged from 0.12±0.10 site B to 0.64±0.24 site C while the range of NO2 and CO were 0.43±0.21 site B to 0.70±0.25 site A, 0.89±0.36 site C to 1.03±0.56 site D respectively. CO recorded the highest concentration in all the sites studied followed by NO2 while NH3 had the least concentration. In this study, all the results obtained were not above World Health Organization (W.H.O) standard (NO2=20.1 ppm, NH3=67 ppm, CO = 2.68 ppm, and H2S = 0.03 ppm). Therefore, the air quality of these campuses' business centers is conducive for now.
