Statistical Analysis and Assessment of Transportation Effect on Air Pollution in in Falluja City, Iraq

Falluja City suffers from air pollution due to the increase in the number of vehicles, the intensity of their movement in city streets, and the organization of urban transport within the city. The aim of this study is the effect of transportation on the concentration of air pollutants such as CO, CO ₂ , SO ₂ , NO ₂ , and HC in Fallujah. The concentrations of the mentioned pollutants were measured at nine traffic intersection locations, including Al-Hadra, Street 40, Maysaloun, East Fallujah, Alatifa, Kamalyat, Thathar, Al-Naziza, and Al-Takwa for five months period, starting from September (2023) to February (2024) The results showed that the highest CO concentration was in the Naziza area in November, reaching 2.85 ppm in the Naziza area, while the highest CO ₂ concentration was 400 ppm in the Hadara area in October. The highest concentration of NO ₂ reached the 40th Street area in November, while the SO ₂ concentration reached its maximum concentration in the 40th Street area, where it reached 0.78 ppm. As for the concentration of hydrocarbons, the highest concentration was 800 ppm in the 40th Street area in October. As for the spatial change, it is clear that the 40th Street area had a very high concentration of pollutants, and this is due to Traffic congestion at intersections. Statistical analysis of pollutant concentrations using one-way ANOVA using the Excel program it was understood that the variation in concentrations of different parameters based on stations are at P < 0.05 and significant since all F statistical values greater than F crit the null hypothesis can be rejected since There is evidence that not all the means are different.
