This study investigated the environmental and health impact of gas flaring of the OML147 flow station located at Owa-Alidinma, Delta State. Air quality parameters were measured in four locations. Carbon (iv) oxide, CO2, measurements were carried out using a non-dispersive infrared (NDIR) analyzer, particulate matter PM2.5 and PM10 measurements were conducted using beta attenuation monitor (BAM) and a tapered element Oscillating microbalance (TEOM) respectively. Noise levels were assessed using a sound level meter. Nitrogen dioxide, NO2, measurements were carried out using a chemiluminescence continuous analyzer. Simple statistical tools of mean, standard deviation, standard error and percentage were employed in the analysis of data. The mean values of the air quality parameters studied in this paper when compared with WHO guideline limits were PM2.5 (0.009𝜇𝑔/𝑚3 < 15𝜇𝑔/𝑚3 ), PM10(0.014𝜇𝑔/𝑚3 < 15𝜇𝑔/ 𝑚3 ), NO2(0.070𝜇𝑔/𝑚3 < 25𝜇𝑔/𝑚3 ), O3(0.018𝜇𝑔/𝑚3 < 100𝜇𝑔/𝑚3 ), SO2 (undetected), CO(0.200𝜇𝑔/𝑚3 < 4𝜇𝑔/𝑚3 ). These were all below the WHO and NUPRC guideline limits and so negative impacts on the ecosystem are unlikely. The noise level mean value (86.8dBA) compared to 70dBA and 75dBA recommended by WHO and NUPRC respectively were higher by 24 % and 15.7 % respectively
