Abstract :

This study aimed to evaluate the concentration of heavy metals in soil samples collected from areas adjacent to Babaei Highway and Yas Fatemi Park. The aim of this study was to investigate the effect of highways on soil pollution and to understand the environmental impact of urbanization and traffic pollution on soil quality.

Soil samples were systematically collected from different locations along Babaei Highway and Yas Fatemi Park. Statistical analysis was performed to evaluate the data and identify potential sources of contamination. The research involved sampling from different locations along the highways to measure heavy metal concentrations. Using GIS software, the IDW method was used to model the spatial distribution of these metals, which allowed for a detailed analysis of their concentration levels in relation to proximity to highway traffic. The results showed different concentrations of heavy metals at the sampled locations, with significant levels of metals. These data indicate potential contamination hotspots that could impact environmental and public health. This study provides valuable insights into the environmental consequences of highway proximity on heavy metal distribution, which will help to understand pollution dynamics and inform future environmental management strategies.
