Air pollution caused by burning fossil fuel is a threat to human health and climatic change. Traffic congestion increases vehicle emissions and the resulting air pollution. This research examines the ambient air quality around the university highway of Northern Technical University (NTU), Mosul city, Iraq. Major pollutants such as benzene, toluene, ethylbenzene, and xylene (BTEX), fine particulate matter (PM2.5), carbon monoxide (CO), nitric oxides (NO), nitrogen dioxide (NO2), nitrogen oxides (NOx), and ozone (O3), were measured for a period of 90 days using mobile laboratory devices. Meteorological sensors were also utilized to record air temperature, wind speed and direction, humidity, and pressure, and all the data were analyzed. The pollutants concentrations were further analyzed using Pearson correlation analysis (PCA). The results revealed that the levels of NOx, PM2.5, and O3 were high, and the maximum benzene value was found to be 9.84 µg/m3 exceeding the established annual limit value of 5 µg/m3 by air quality guidelines and standards. The study is a valuable reference for air pollution and air quality data for Mosul city. The result could be helpful in monitoring and development of the most affordable strategy for air pollution remediation and implementation of control measures for the city of Mosul.
