Concentrations of lead in the dust of some fuel stations in Salah al-Din Governorate

This study was carried out in the city of Tikrit and its environs, where environmental pollution with lead was studied in some governmental fuel stations in Salah al-Din Governorate, where cars often gather for refueling, resulting in vehicle exhausts varying proportions of the pollutants emitted from them, including the element lead. 
The study was divided to include five sites, four gas stations and a fifth group for control, which are: the old Tikrit gas station, Fateh al-Futuh fuel station (al-Qadisiyah station), al-Dour gas station and the martyr Umayya Jibara station (al-Alam station), and the fifth site (the control site) In the Naamah area outside the preservation center on the roads leading to the Kirkuk governorate, which is approximately 40 km away from the research project stations. 
The text of the research is to take samples from the dust scattered on the floor of these stations and the control group for a period of six months with a sample per month, from November 2019 to April 2020. 
The results the study were determined by measuring the concentrations of lead present in the dust belonging to these stations by means of a Flame Atomic Spectrometer. 
The results showed that there were significant differences between the stations and the control group, so the results recorded the highest concentration of lead in dust for the average of the stations during the six months (0.1543 ±0.01112 mg/L) in the Al-Dour governmental fuel station, and the lowest concentration (0.0831 ± 0.0708 mg / L) in the Fath Al Futuh station. 
 (Al-Qadisiyah station), while the concentration of the control group was (0.0387 ±0.0316 mg/L). The reason for the high results of these measurements on the control group may be attributed to the high traffic movement of cars, the lack of vegetation and the frequency of dust storms that the study area is exposed to from time to time, in addition to other industrial activities in the area under study.
