Environmental impact of fuel stations on some heavy metal concentrations in nearby surface crust soils in urban areas: A case study of soil heavy metal contamination

Abstract

In the present study, the chemical analysis, related to heavy metals (Pb, Ni, Zn, Mn, and Fe) which considered the main source of pollution in soils that come from several sources, was carried out near a three fuel stations to reveal their effect on heavy metals in the nearby soils. Samples were collected from soils which are near to three Fuel stations in Al Hilla city, as a case study, it was found that the concentrations of these metals are all below the value that should be available in average shale, except that for Pb. The average concentration of metals in samples was Pb (25.47 ppm), Ni (86.65 ppm), Zn (84.38 ppm), Mn (96.71 ppm), and Fe (112.38 ppm), and a statistical analysis is done for these results to find correlations coefficients among studied elements, and the results suggested that the fuel station may compromise the nearby soils by increasing Pb concentrations in them.
