One of the actual challenges in urban environment is represented by the road dust and it control, due to the high temporal and spatial variability of the sources: soils, traffic, and industrial activity with an important negative impact on inhabitants. Assessment the concentrations of heavy metals from road dust and establish correlations with urban environment characteristics, represent the aim of the current study. After field observations, were established the sampling points, the samples being collected in March 2013. Results indicate the metal concentrations in road dust were generally lower than those in soil. Based on the average concentrations, the order for dust metal concentrations was Mn>Zn>Cu>Pb>Cr>Ni>Co>Cd, establishing correlations with soil metal concentrations the order being slightly different Mn>Zn>>Pb>Ni>Cr>Co>Cu>Cd. The spatial distributions of metals in the road dust reveal three main polluted areas, located into larger road crossing of the city as Podu Ros and Tudor Vladimirescu and in industrial area, located in southern part of the city. In opposition the northern part registered the lowest values due to the plenty of green spaces, the better state of roads etc. Road dust heavy metals concentration fit under the limit values for human health protection, describing different spatial pattern, in accordance with heavy metals soil concentrations and urban morphology and functionality.
