Air pollution represents the largest portion of all environmental risks which accounts for over 3 million deaths globally. It is a significant factor for a number of health conditions including respiratory infections, heart disease and stroke and in 2016 alone, long term exposure to air pollution contributed to deaths of 6.1million people, with stroke, heart attacks, lung disease and lung cancer. Air pollution monitoring is particularly sparse at ground level in Africa and with increasing industrialization coupled with traffic congestion, emission are not regulated and fuel tankers often catch fires on the street thus, Aim and Objectives: this study is targeted at assessing the ambient air quality - by measuring the concentrations of eight (8) key air pollutants ( CO2, PM2.5, PM10, H2S, VOC, LEL, formaldehyde and O2) - at various sites within Temidire Irewolede Community (TIC), Ilorin West Local Government Area of Kwara State; assessing the health effect caused by the air pollutants (through comparison of the concentrations of these key pollutants morning and afternoon); and assessing the damage caused on human health within this community. Methodology: The study adopted a random sampling technique with total number of 24 sample points within the study area (TIC).Data was collected with the aid of a structured questionnaire, Handheld Germin (GPSmap® 78) GPS and samples of the different concentrations of pollutants were collected in the morning and afternoon between 9.00am and 6.00pm using Hand held mobile multi-gas monitor with model AS8900, BLATN with model BR – Smart Series air quality monitor, and air quality multi-meter with model B SIDE EET100. Inferential Statistics and ArcGIS software were used to analyze data collected. Results: Analysis of the variation of ambient quality of all the pollutants in the Morning was ; PM2.5 (58.2083 µg/m3), PM10 (33.7826µg/m3), H2S (2.3382µg/m3), VOC (47.7248µg/m3), LEL(8.2083µg/m3), Formaldehyde (0.1174), O2 (19.3778ppm) while for Afternoon :PM2.5 (71.2217µg/m3) PM10 (52.652200µg/m3) H2S, (20.8391 µg/m3 ), VOC (0.5856µg/m3), LEL (2.3913µg/m3), Formaldehyde (0.4996), and O2 (20.8391ppm). The comparison of dispersal level of pollutant for TIC is as follow; Morning CO (899.1667µg/m3), PM2.5 (68.25417µg/m3), PM10 (50.45833µg/m3), H2S (9.0375µg/m3), VOC (0.561208µg/m3), LEL (7µg/m3), Formaldehyde (2.59), O2 (21ppm) while afternoon include: CO (975µg/m3), PM2.5 (68 µg/m3), PM10 (89µg/m3), H2S (25µg/m3), VOC (0.561208µg/m3), LEL (2.291667µg/m3), Formaldehyde (0.47875), O2 (19.97083ppm). Conclusion: In conclusion , the concentration of the air pollutants (most especially CO,) exceeded the permissible limits, which is an indication of the level of industrial, traffic and domestic emissions. it can be concluded that all things being equal, the pollutant from the industry and the questionnaire, shows that the factory in TIC has impacted negatively as a result of their industrial activities, if this situation is not checked, it will lead to environmental disaster as nobody selects the air he/she breaths Recommendations: Thus the quality of air around the community need to be regularly monitored to ensure compliance of the presence of the company within the community with recommended regulations in order to mitigate the adverse effects of these pollutants on human health and enlightenment campaign on the effects of these pollutants on human health is recommended..
