Iraq is one of the regions most affected by climate change around the world. These multidimensional effects of climate and pollution must be taken into consideration when estimating both climate and air pollution-related impacts, in order to develop appropriate health policies and measures to address both current and future climate and pollution challenges. The study was conducted in the Iraqi governorate of Salah al-Din, during the fall, winter and spring seasons of the year 2021-2022, with the aim of evaluating the level of pollutants in the atmospheric air for three regions: Abotuama rural area, Baiji oil refinery and the city of Tikrit. The concentrations of each of the toxic gases were measured: SO2, NO, NO2, HCL, HF, TVOC, CO2 and CO, as well as temperatures. Significant differences were found between the study locations and seasons for all the variables that were tested, as Baiji refinery recorded the highest concentrations of SO2, NO, NO2, HCL, FH and TVOC at 3.5 ppm, 10.78 ppm, 7.475 ppm, 13.1 ppm, 0.8 mg m-3 and 15.25 ppm, respectively. The site of Tikrit recorded the highest concentrations of CO2 and CO, which were 1016 ppm and 29.85 mg m-3, respectively. While the spring season recorded the highest concentrations of SO2, HCL, TVOC and CO compounds, followed by the winter season of NO2, FH and TVOC compounds, the temperature rates were identical in the three study sites and during the fall, winter and spring seasons, reaching 30.25, 12.5 and 31 & DEG;C during the three seasons, respectively. The results of analyzing the relationship between temperature and pollutant concentrations showed that SO2, NO, HCl, and CO increase in hot seasons, while NO2, HF, TVOC, and CO2 pollutant concentrations increase during cold seasons.
