Abstract

The analysis of some outdoor atmospheric aerosols such as PM_2.5, SO₂, CO and CH₄ in Federal capital territory (FCT) Abuja, Nigeria was carried out, the study covered all the six (6) area councils “AMAC, Abaji, Bwari, Kuje, Kwali and Gwagwalada” of the FCT. Analysis was conducted for a cumulative data of one year period (2017-2018) based on monitoring satellite data within altitude of 6 Km from the ground levels, which was collected by National Space Research and Development Agency (NASRDA), Abuja, Nigeria. The data came in NETCDF format, extracted by a specialized software called the Arc Map 10.4.1, converted and exported in DBF format which can be read by Microsoft excel. Result of the analysis shows the pollutant various Air Quality Index (AQI) and pollutant mean concentrations (PMC), also the AQI and the maximum concentration of each pollutant in all the study areas were compared with the respective annual standard set by WHO, SO₂ was found to be ten thousand (10,000) times above 20 μg/m³, CO is within the safe range, 10 times lower than 0.01 ppm, PM _2.5 was (2) times lower than 10 μg/m³ and CH₄ are above the WHO/NIOSH threshold limit value of 1000 ppm with 50 percent increment. The effect varies for a different group of people (sensitive to insensitive), therefore they are said to have a deterministic effect.
