Determination of Cu, Pb, and Zn Contents of Soils Formed on Different Parent Materials (Çanakkale, Türkiye)

Abstract

This study was carried out to determine the heavy metal (Cu, Pb, and Zn) contents and their differences in soils formed on three different parent materials (basalt, clastic and carbonate rocks and granite) in the Ezine district of Çanakkale province. For this purpose, surface sampling was conducted in soils formed under natural conditions on different geological materials. Heavy metal contents of the soil samples were determined using flame atomic absorption spectrometry using the wet digestion Aqua regia method. Analysis of variance (ANOVA) was used to determine the elemental differences in soil samples. Pearson correlation analysis was applied to reveal the relationship between heavy metals and the physicochemical properties of soils taken from different parent materials. As a result of the evaluation, the mean Cu concentrations in the samples ranged from soils formed on basalt (40.8 ± 3.8 μg/g)> soils formed on clastic and carbonate rocks (24.8 ± 1.5 μg/g)> soils formed on granite (22.5 ± 2. 8 μg/g); mean Pb concentrations followed the order of soils formed on granite (37.50 ± 3.30 μg/g)> soils formed on clastic and carbonate rocks (35.67 ± 2.74 μg/g)> soils formed on basalt (21.6 ± 6.7 μg/g). The mean Zn concentrations of the soil samples were as follows: soils formed on basalt (80.9 ± 8.7 μg/g)> soils formed on clastic and carbonate rocks (44.1 ± 3.7 μg/g)> soils formed on granite (37.0 ± 9.4 μg/g). Pb concentrations of all soil samples were found to be higher than the average of the earth's crust.
