摘      要：The work of “Monitoring and Evaluation of Air Pollution the main aim of this work is to measure the concentrations of gases which include CO2, CO, NOx, SOx and thermal radiation and carry out an analysis of the measured data. This experiment was scheduled to take place at Egbema flow station which is managed by NPDC (Nigerian Petroleum Development Commission) Shell location 2 in Obiakpu, Ohaji Imo state. The bad effects of these pollutant gases on the community can include cause of diseases to plants and animals, causes of physical ailments in the respiratory tract of humans, and death and degradation of the surrounding environment. The parameters measured during this exercise include the distance from the flow station, latitude and longitude of the distance measured on the earth’s surface, time for the experiment and the concentration of pollutant gases. The instrument used includes CO meter, CO2 meter, SOx and NOx meters, and thermal radiation meter. The gases were measured in three different time intervals between 10:50 am - 11:23 am (for CO: 0.02 ppm, 0.01 ppm, 0 ppm, 0 ppm, 0.01 ppm, 0 ppm;for CO2: 0.04 ppm, 0.01 ppm, 0.01 ppm, 0.02 ppm, 0.01 ppm, 0 ppm;for SOx: 0 mg/m3, 0 mg/m3, 0 mg/m3, 0 mg/m3, 0 mg/m3, 0 mg/m3;for NOx: 0.127 mg/m3, 0.098 mg/m3, 0.12 mg/m3, 0.122 mg/m3, 0.113 mg/m3, 0.103 mg/m3;for thermal radiation: 57.4 W/m2, 61.5 W/m2, 65.1 W/m2, 64.9 W/m2, 81.9 W/m2, 148.3 W/m2), 1:30 pm - 2:13 pm (for CO: 0.01 ppm, 0.02 ppm, 0 ppm, 0 ppm, 0.1 ppm, 0 ppm;for CO2: 0.01 ppm, 0.01 ppm, 0.01 ppm, 0.01 ppm, 0 ppm, 0 ppm;for SOx: 0 mg/m3, 0 mg/m3, 0 mg/m3, 0 mg/m3, 0 mg/m3, 0 mg/m3
