The Content of Heavy Metals (Cu, Zn, Cr, Ni, Pb) in The Soil Near The Arterial Roads in Wroclaw (Poland)

Abstract

The concentrations of heavy metals in soils along the motorway bypass of Wroclaw (AOW) and the Eastern Ring Road of Wroclaw (WOW), Poland, have been determined. The soil samples were collected from the levels of 0-25 cm within 2 m from the edge of the road. The mineralizates were prepared in HNO 3 , 60%, using the Microwave Digestion System. The content of Cu, Zn, Cr, Ni and Pb in soils were determined using FAAS method. The physicochemical parameters, the conductivity and pH of the soil solutions were measured to evaluate the salinity of the soils and their active and exchangeable acidity. The pollution indexes (W N) showing the enrichment of soils in metals have been determined. Excess of metal concentrations in soils compared to the geochemical background in uncontaminated soils of Poland has been observed. Permissible concentrations of heavy metals relative to the standard for soils, according to the Polish Ministry of Environment Regulation from September 1 st , 2016, have not been exceeded.

A Location Intelligence System for the Assessment of Pluvial Flooding Risk and the Identification of Storm Water Pollutant Sources from Roads in Suburbanised Areas

“…As one of the largest and most rapidly developing Polish cities [71], Wrocław is impacted by uncontrolled suburbanization [72,73], farmland degradation [74,75], and landscape deformation [76,77]. As a consequence, there are many negative effects of rapid urbanization, such as rising low emission and environmental pollution by traffic flow [78][79][80], changes in biodiversity and ecosystem services [81], thermal stress [82,83], as well as numerous economic and social implications [84,85]. Wrocław and its suburbs are mostly lying in the valleys and floodplains of the River Odra and its tributaries.…”
