Background and Objective: The presence of spatial changes in soil properties is normal, and it is inevitable to recognize these changes, especially in green spaces, for careful planning and management. On the other hand, with the increasing need of communities for transportation, communications and the use of vehicles, it has become increasingly common for cars to be the main source of heavy metal pollutants in cities. The aim of this study was to evaluate the physical and chemical limitations of green space soil and also to determine the concentration of lead and cadmium as indicators of traffic pollution of Imam Reza (AS) passenger terminal in the southwestern part of Mashhad.
Analysis method: Sampling was performed at 129 points at a depth of 20-0 cm. On the other hand, to determine the deep characteristics of the soil, three soil samples were described and sampled. Element mapping maps were prepared using statistical methods in ArcGIS software.
Results and Discussion: The results of this study showed that the most important limitation of these soils is their shallow depth, which mainly lacks sufficient depth for the growth and development of trees with deep root systems. On the other hand, the concentration of nutrients in the soil was lower than sufficient. The prepared zoning maps also indicate that these changes are spotty and that the area needs local management. The concentration of cadmium contaminants is also high in the threshold area, but for lead, soil contamination is not currently serious.
