In this study, the quantity of deposited particles on some trees leaves at Syrian coast has been determined; and the seasonal changes in the concentration of trace metals (Zn,Mn,Cd,Pb) at both sides corresponding to the land and sea have been identified. This study has been performed on Melia azedarach, Cupressus sempervirence, Eucalyptus camaldulensis dehnh, Acacia cyanophylla lindley, Nerium oleander, and Phoenix dactylifera trees to determine the most effective type in the detention of marine aerosols.
The results of this study showed that the particulate matter retained on the trees leaves and the concentrations of zinc and manganese inside it increase in the site corresponding to the sea more than it is in the site corresponding to the land, while the concentrations of lead and cadmium decrease in the site corresponding to the sea more than it is in the site corresponding to the land. On the ground that the zinc and manganese are present in abundance in marine water unlike lead and cadmium which are rarely present, this research confirmed the positive role of these trees in the detention of marine aerosols volatiles in the air.
This study demonstrated that the Nerium oleander trees retain the most quantity of particulate matter and then the trees: Melia azedarach, Acacia cyanophylla lindley, Cupressus sempervirence, Eucalyptus camaldulensis dehnh, and Phoenix dactylifera respectively. Moreover, the deposited particles on the trees leaves increase in the sites close to the industrial activities and traffic jam specially in summer and autumn, and then decrease in the sites which are relatively far from pollution sources.
