Investigation of some heavy metal pollution in asphalt powders in Sinop-Samsun highway

In this study, the metal contents (Pb, Cd, Ni, Cr, Cu) of soil samples taken from 17 points on Sinop-Samsun highway were compared and the pollution levels between the regions were determined. Asphalt dust collected in 10 km intervals was dried in laboratory and analyzed by Inductively Paired Plasma-Mass Spectrometer (ICP-MS / MS). In the analyzes, the average Pb value was found to be 8,78 mg / kg dry soil, mean Cd value was 0,12 mg / kg dry soil, mean Ni value 17,18 mg / kg dry soil, average Cr value 28 mg / kg dry soil, average Cu and 33,06 mg / kg dry soil. Also; The data obtained from the ICP-MS / MS device were statistically evaluated by using the SPSS version 22 package program and, while the correlation analysis results were evaluated, it was found that there was a positive and significant relationship between the collected powder samples. The data of the soil samples obtained from the study results, Turkey and heavy metal levels compared with the permissible land in the world; usually, heavy metal accumulation in soil did not exceed the acceptable limit value.
