Heavy metal concentration along road sides of Quetta, Pakistan.

The concentrations of heavy metals (Mn, Cu, Zn, Ni, and Pb) were estimated from the tree leaves of Morus alba, Fraxinus rotundifolia and Pinus halepensis along the road sides of Quetta, Pakistan. The concentration of these metals started gradually increasing during spring, summer and reached to its maximum value during autumn season. The metal contents were significantly high as compare to control areas. Average Cu was 2.51mg/g-1, Mn 10.81, Ni 1.32, Pb 3.37 and Zn 8.82. Maximum concentrations of these metals were recorded from Jinnah Road and Sharah Iqbal being the main roads these have maximum traffic density. The concentration of metals was directly correlated to the number of vehicles ply on the roads. This indicates that vehicular emissions were found to be mainly responsible for the heavy metal concentrations in tree leaves. Severe drought and sewerage water supplied to these trees also played an important role.
