- W2911556280 abstract "Heavy metals, such as Cu, Zn, Cd and Pb are common pollutants in urban environments mainly due to traffic emissions. The present project work was focused to study Cu, Zn, Cd and Pb concentrations in high traffic density roadside soils of some selected sites of Eastern Ethiopia. In the present work, the soil samples were collected from four roadside soils of both sides of the selected sites and analyzed for the concentrations of Cu, Zn, Cd and Pb. Soil samples were collected symmetrically at distance of 0, 25 and 50 meters from both sides of the main road of the town of the selected sites. The concentrations of Cu, Zn, Cd and Pb were analyzed with the help of flame atomic absorption spectrometry (FAAS). The levels of Cu, Zn, Cd and Pb in all the studied roadside soils were ranged from 12.02 to 79.24, 6.76 to 78.10, 0.08 to 0.64 and 0.16 to 0.89 mg kg -1 respectively. These concentrations were below the critical maximum levels above which toxicity is possible. This shows that the levels of Cu, Zn, Cd and Pb in the study areas were low. In addition to this, the levels of all four heavy metals in both sides of the roadside soils exhibited a decrease with the increasing distance from the main road andthe concentrations in two sides of road at the same distance were not found close to each other because of differences in directions and strength of winds in these regions." @default.
