( Zn , Cr , Cd , Co , Mn , Fe , Pb , Cu ) in the Soil and Leafs where the study was conducted .
The Flame Atomic Absorption was used to measure the concentration , these measured concentrations
was compared with the National and World Standards to determined which places were polluted and to suggest the suitable solutions for ( 10 ) traffic stations in the city where the samples were taken under aspecific climate measurment .
