Assessment the Air Pollution at the some Areas in Salahaddin Governorate - Iraq

Abstract

The study was conducted in Salah al-Din Governorate - northern Iraq, during the period from 1/11/2021 to 30/3/2022, with the aim of evaluating the level of pollutants in the atmospheric air for three areas: Al-Boutama (rural area), Baiji refinery (oil industry area), and the city of Tikrit (a densely populated area), the concentrations of toxic gases were measured: sulfur dioxide (SO2), nitrogen oxide (NO), nitrite (NO2), hydrochloric acid (HCl), hydrogen fluoride (HF), carbon dioxide (CO2) and carbon monoxide. (CO), using the Wolf Pack Modular Area Monitor. The results were as follows: Significant differences were found between the study sites for all the variables tested, and Baiji refinery recorded the highest values for each of the variables SO2, NO, NO2, HCl and HF, which amounted to 2.54, 8.28, 6.4, 10.62 ppm and 0.42 mg/ m3, respectively. November 2021 recorded the highest concentrations of HCl and CO compounds with averages of 7.6 ppm and 18.37 mg/m3, respectively, while January 2022 recorded the highest averages of NO2, HF and CO2, which amounted to 5.27 ppm and 0.4 mg/m3 and 791 ppm, respectively, the interaction between Baiji refinery site and the months of November, December and January recorded the highest concentrations of pollutants amounting to 4.4 ppm for SO2 concentration, 11.2 ppm for NO concentration, 7.9 ppm for NO2 concentration, 13.8 ppm for HCl concentration, and 0.7 mg/m3 for HF concentration, and 16.5 ppm for VOCs concentration.
