  Background and Objective: Today pollution in the large cities has become a basic challenge for the environment. In Ahwaz, 60% of the pollution is related to the mobile sources which produce a huge amount of various pollutants including CO and PM10 that affect the life of the residents in Ahwaz. CO is an important pollutant emitted to the atmosphere from traffic. Generally, pollutant emission to the air has a significant effect on air pollution control. Therefore, the of this study was to investigate the dispersion and density of CO and PM10 from mobile sources. Method: In this study, at first the study area was zonned (3×3 Km). Then, in each net the number of cars were estimated according to the types of car and hours of traffic. Consequently, the whole diffusion of CO and PM10 concentration in each net was estimated according to gram per second for each car considering the diffusion factors, type of consumed fuel and the distance drived. Finally, for better illustration of places, graphic exhibition, distribution way of the mentioned pollutant and diffusion, GIS a software was used. Conclusion: The pattern of pollutant diffusion for CO and PM10 emitted from cars, which is calculated by the model, shows that most of the polluted areas are the business and administrative centers. These pollutants were calculated to be very low and even zero at the outskirts of the city. Manuscript profile

  Important heavy metals such as lead are part of the pollutants produced by vehicles and the traffic flow causes them to be released into the urban environment. In order to study the pollution rate of street margin trees and determining the traffic parameter affecting the amount of lead in plane tree of Rasht city, a case study was selected in this city from four stations on the outskirts of the city for traffic and low traffic. Traffic factors including three superficial stations based on traffic volume per day and per month and a low traffic station. The method was used to determine that 60 species of plane tree at 30 meters intervals were randomly selected from the total tree crown area to determine the amount of adsorption of heavy lead metal which was selected from each sample with amount of 10 grams to test the absorbed lead content. The results of this study showed that lead absorption by plane tree species in three stations and control station, Takhti St. Station had the highest amount of lead (29.53 ppm) than the other three stations. Therefore, the plane tree species can be a suitable type for the margin of streets in the urban area. The results of this research can be used in transportation management and urban traffic control and urban design and urban design and planting. Manuscript profile
