Abstract
Variability in concentrations of heavy metals in soils near outlet roads in Warsaw.
A b s t r a c t . The contents of Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb, S, V and Zn in soil samples collected at 15 outlet roads fromWarsaw were determined by ICP-OES. Samples were collected at distance of 1, 5 and 10 m from the edge of surface of the roadway, with from a depth of 0–20 cm to 40–60 cm. The highest reported concentrations of heavy metals were found in soils near roads leading to Góra Kalwaria, Katowice and Poznań, and the lowest — near those leading to Gdańsk, Radzymin and Mińsk Mazowiecki. The investigated soils were characterized by contents of copper, zinc and lead, and, to a lesser extent, nickel and chromium increased in relation to the geochemical background. In most of the examined soil cross-sections the decrease in contects of heavy metals along with increasing distance from the road edge was noted. In some locations, accumulation of metals in soils appear to be strongly influenced by local terrain micro-morphology, conditioning the lines of rainwater runoff from the road
