This study was conducted to examine some vehicular emissions pollution and the consequences those emissions have on the environment when they are released into the air on our highways. Every day, more secondhand cars are being brought into Nigeria, which adds to the rising pollution levels in the environment. Using the Ilorin axis as a case study, this study investigated the impact of car emissions on the ecosystem. A vehicle emission test experiment was conducted on 65 automobiles at the University of Ilorin, Faculty of Engineering, University of Ilorin Teaching Hospital, and Kpataloje Mechanic Site in Ilorin, Kwara State, to evaluate the levels of Carbon Monoxide (CO) and Nitrogen Oxide (NO2) produced by gasoline-powered vehicles. Exhaust Gas Analyzer Monitor (Aeroqual Series 500) with sensor head mounted on monitor base was used to conduct the emission test. The Exhaust Gas Analyzer sensor inlet was placed 20 cm from the exhaust tailpipe end on stationary automobiles operating at idle speed for five (5) minutes in order to detect Carbon Monoxide (CO) and Nitrogen Oxide (NO2). To ascertain the health impacts in the sample locations, 350 randomly chosen participants from the three research locations in Ilorin, Kwara State, were given a structured questionnaire.
