The purpose of the research is to examine, and compare the spatial distribution of deterioration of air quality, the environmental and health risks within the poor air quality area close to the gas flaring location and assess the density of gases and pollutants produced using the Gaussian-Plume model (GPM). Geographic Information Systems GIS technology has been combined with GPM in dispersion modeling. The gases produced by gas flaring to be emitted include sulfur dioxide (SO2), Nitrogen dioxide (NO2), and particulate matter (PM). Such pollutants worsen the quality of air and, therefore, are harmful to the health of the surrounding communities. Findings demonstrate that pollution intensities increase the most in locations proximate to flaring sites since atmospheric factors govern the way pollutants disperse. The GPM indicates that pollution concentrations decrease as distance increases from the sources. While some areas near the flare still contain unsafe levels, even in inhabited sections. Strict regulations with improved monitoring, together with cleaner technologies, must be adopted. This is for reducing the environmental and health effects of gas flaring in Kirkuk. This paper adds to the environmental sustainability investigation by proving the power of GIS-based spatial analysis and dispersion modeling for monitoring air pollution variations at different locations. The research produces a combination of strategies that use GIS-based approaches in decision-making as well as dispersion modeling to inform better policymaking on environmental matters related to gas flaring.  https://jpoll.ut.ac.ir/article_103819_7bab7cda646acfc98ea364e10d0365ec.pdf
