Abstract: In most of the African studies, PM concentrations exceed WHO limits. In this study, assessment of air quality indices and its health impacts in Ilorin metropolis, Kwara State, Nigeria was assessed. Interestingly, what’s more, the ambient air quality measurement was done with respect to Particulate Matter (PM2.5 and PM10), Volatile Organic Compound (VOC), Combustible (LEL), Formaldehyde, Temperature, Relative Humidity and Oxygen (O2)in Temidire Irewolede community at twenty-four (24) locations for eight weeks. The air pollution measurements were carried out using direct reading, automatic in-situ gas monitors; Hand held mobile multi-gas monitor with model AS8900 (Combustible (LEL), and Oxygen (O2)), BLATN with model BR – Smart Series air quality monitor (PM10, Formaldehyde) and air quality multimeter with model B SIDE EET100 (Dust (PM2.5), VOC, Temperature and Relative Humidity). The results showed the mean concentrations of PM2.5(64.9), PM10(43.2), Combustible (LEL) (5.4) and Formaldehyde (0.3) are generally lower and within acceptable range of National and International regulatory standards for air quality indices. There are however, few exceptions such as mean concentrations of VOC, Oxygen and Formaldehyde respectively high compared to National and International standards. These high values were attributed to the amount of pollutants present in the air because of anthropogenic activities from the industries. Hence, air pollution in Ilorin Metropolis was however found to be relatively polluted. It can therefore be concluded that drastic efforts must be made to reduce air pollution levels. Comprehensive air quality monitoring and adequate measures should be implemented. There is also a need for the continuous monitoring and auditing of PM2.5 and PM10 in the community to safeguard the health of the public and the environment.

Keywords: Air quality index, Health Impact, Particulate Matter (PM2.5 and PM10), Combustible (LEL) and Formaldehyde.
