| The objective of the current research is evaluation the distribution, source, and environmental health risk of polycyclic aromatic hydrocarbons (PAHs) compounds in soil samples taken from vicinity of Tehran-Semnan road, Iran. This road is a densely populated one in central northern part of Iran with a heavy load of vehicular traffics and several industrial complexes. Four different sampling sites (S1 to S4) were selected in studied area and then concentration of 16 PAHs compounds in taken soil samples were measured by High Performance Liquid Chromatography (HPLC). Total PAHs concentrations varied significantly from 148.4 ng g-1 to 721 ng g-1. The Siman e Tehran (S1) site has the highest average total PAHs concentrations (654.55 ng g-1) and Dehenamak (S4) has the lowest average total PAHs concentrations (168.7 ng g-1) among studied sites. The obtained total PAH concentrations in studied soil samples are relatively lower than those reported in the literature for similar areas. The diagnostic ratios of fluoranthene to pyrene (Flu/Pyr) and phenanthrene to anthracene (Phe/Ant) were used to determine the petrogenic and pyrogenic sources of PAHs, respectively. The derived results indicated that PAHs contamination in majority of studied soil samples caused by both petrogenic and pyrogenic process. | ||
