THE UNIVERSITY OF BENIN

This research examines air quality and noise pollution within the University of Benin, Ugbowo Campus, to determine how environmental factors influence the health, comfort, and productivity of individuals in the university community. With increasing urban activities, traffic congestion, and generator use across the campus, the issue of environmental pollution has become more significant. The study assessed four major air pollutants, particulate matter (PM₂.₅ and PM₁₀), carbon monoxide (CO), and ozone (O₃), and evaluated noise levels in various campus zones to provide a comprehensive understanding of environmental quality in the study area. Data were gathered using an air quality monitor and ozone meter for air pollutant measurement and an Extech sound level meter for noise. The Air Quality Index (AQI) was used to interpret pollutant concentrations, while Geographic Information System (GIS) mapping helped visualize spatial pollution patterns across the campus. Results showed that air quality across the campus ranged from good to moderate, with AQI values between 26 and 55. Cleaner conditions were recorded at the College of medical sciences and Halls 6 and 7 (26 – 31), while higher values occurred at ekosodin back gate, 55 and at Main gate,47, influenced by vehicular and commercial activities. PM2.5, PM10 and CO concentrations were also higher at these gate areas, whereas ozone levels remained low reading from 0.01 – 0.07 ppm. In contrast, noise levels often exceeded standards in busy zones, reaching 86.7 dB(A) at ekosodin back gate and above 80 dB(A) in other active areas, surpassing the WHO daytime limit of 55 dB(A). The study concludes that while the overall air quality on the University of Benin campus remains within acceptable limits, noise pollution presents a more serious challenge. To improve environmental conditions, the study recommends effective traffic regulation, proper control of generator use, expansion of vegetation and green zones, and consistent air and noise monitoring. These actions will enhance sustainability and ensure a cleaner, quieter, and healthier learning environment for all campus users.
