Evaluation of air quality index (AQI) and health impact in Khanaqin Region, Iraq.

Data from four monitoring sites in the Khanaqin Region of Iraq for the years 2018 to 2021 were studied. This data included total suspended particles, O3, SO2, NO, NO2, and CO. Therefore, a calculation of the monthly quality indices using the US EPA and UK methods is done. The entire air contaminants (excluding carbon monoxide) varied between both the high and low levels set by Iraqi and international regulations, considering the fact that most air pollutant concentrations in the Khanaqin District have been gradually declining in the past few years, they often appear greater than natural air quality. The findings demonstrate that the TSP average for the years 2019 to 2021 was extremely high, raising concerns for the people of Khanaqin. The study's findings indicate that the area's main contributors to (Sulfur dioxide / Carbon monoxide) concentration ratios, with a value below one are vehicle emissions into the atmosphere. In comparison to other seasons, it has been found that summer has the highest quantities of the majority of contaminants. Traffic volume, home generators, and atmospheric chemical processes are all associated with the highest quantities of pollutants. API and AQI indexes provide for an extra evaluation of the conditions of air quality in addition to single air pollutant requirements. When using the UK method, low pollution is assumed with all contaminants except TSP. [ABSTRACT FROM AUTHOR]
