Heavy metal contamination of roadside soil near sun highway in Romania

Abstract

In order to assess the impact of car emissions on the soil, studies are required to monitor the concentation heavy metals from roadside soils. In this paper, we report an extensive survey of the roadside soils contamination with heavy metal along the Sun Highway (A2) which connects Bucharest to Constanta. The contents of heavy metals (Cd, Cu, Ni, Pb, Zn, As) were assessed by inductively coupled plasma mass spectrometry (ICP-MS). The car pollution was also studied to link it with the concentrations and distributions of heavy metals in the roadside soils.A comparison between the degree of contamination obtained in the set points was made. Moreover, the impact of the metal concentration value was debated.
