What is it about?
This work shows how the road traffic may affect people who live close to the crowded roads. The study investigates the impact of traffic emission for one of the busiest roads in Najaf Iraq, on the surrounding residential areas. Further, the study explains how the ground level concentrations of three air pollutants (CO, NOx and TVOC) decrease as we move away from road. Further, the prediction results, using SCREEN model, were compared with actual observations at three distances from the road. The predictions of CO and NO2 using USEPA emission factor give much better results than those prediction using EURO 6 emission factor. Also, the results showed that the CO could be considered as the best indicator for identifying the traffic impact on surrounding residential areas.

Why is it important?
Our findings show how the ground level concentrations of TVOC, CO and NOx decreases as we move from the traffic road and highlights the difference between USEPA emission factor and EURO 6 emission factor.
Perspectives
Air quality study for Iraqi cities (especially Najaf, Iraq) is rare and very few scientists worked in this part of the world.
