Abstract : The levels and trend gaseous emissions from aircraft landing and take-off operations and the resulting Air Quality Index (AQI) at the Lagos and Port Harcourt international airports have been investigated in this study for the years 2020-2022. Data for this study was collected from the Nigerian AIRSPACE MANAGEMENT AGENCY In Port Harcourt and Lagos.The levels of gaseous pollutants recorded at the Lagos airport were; CH4 (54190 - 60030 ppm), CO (9443.0 - 9510.9 ppm), CO2 (3162949.6 – 316309.7 ppm) and SO2 (92180 – 94190 ppm) while the Port Harcourt airport recorded levels of CH4 (562.6- 600.7 ppm), CO (822.3 - 942.0 ppm), CO2 (2963254.4 – 316309.7 ppm) and SO2 (11252.9 – 12019.4 ppm). The AQI at both airports showed that the air quality during the landing and take-off operations is hazardous and may pose occupational health risks, thus measures necessary to mitigate these risks should be put in place.
