PEOPLE PERCEPTION OF VEHICULAR EMISSIONS ON AIR QUALITY IN KATSINA METROPOLIS

This study investigates public perception regarding vehicular emissions and their impact on air quality within the Katsina Metropolis, Nigeria. As a rapidly urbanizing center, Katsina faces deteriorating air quality driven by increased vehicle density and the release of pollutants such as Carbon Monoxide (CO), Nitrogen Oxides (NOx), and Particulate Matter (PM). The research was guided by four main objectives: assessing the level of awareness among residents, evaluating perceptions of health and environmental risks, identifying factors influencing residents' attitudes, and providing recommendations for public engagement. The study utilized a theoretical framework incorporating Dispersion Theory, Diffusion Theory, Reaction Theory, and Exposure Theory to understand how pollutants move through the atmosphere and how information about these risks spreads through the community. Preliminary literature review and problem identification suggest that while vehicular emissions contribute significantly to respiratory and cardiovascular health issues, there is a notable lack of comprehensive local data and low public awareness regarding individual contributions to pollution. The scope of the study focuses on spatial pollutant distribution and the vulnerability of specific groups, such as children and the elderly. The findings aim to provide policymakers with actionable insights to develop mitigation strategies—such as improved public transit and stricter emission standards—to safeguard public health and promote sustainable urban development in Katsina.
