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.

Soil is one of the important components of the environment that affects the growth and development of plants. Soil testing is one of the chemical processes in which the suitability of essential nutrients is determined before sowing the crops so that the demand for remaining nutrients can be fulfilled artificially by applying fertilizer in the field. A physicochemical study of soil is based on various parameters like soil pH, Electrical Conductivity (EC), Aluminum (Al), Iron (Fe), Sodium (Na), Phosphorus (P), Potassium (K), Manganese (Mn), Calcium (Ca), and Magnesium (Mg). Ten representative samples were obtained and analyzed for their alkalinity content, pH, electrical conductivity, organic carbon, sodium, and potassium. Ten soil samples were collected at a depth of 0-20 cm and analyzed for soil that was neutral to slightly alkaline. Soil pH ranges from 7.16 to 8.34, electrical conductivity from 62 to 138, aluminum oxide from 0.4 to 0.26, iron oxide from 7.7 to 12.7, sodium oxide from 9 to 31, potassium oxide from 14 to 58, manganese oxide from 2.2 to 14, calcium oxide from 32 to 188, and magnesium oxide from 6.1 to 61. This information will help the farmers know the number of fertilizers to be added to the soil to increase production.
