Usage of Some Woody Tree species to Remediate Contaminants in Agricultural Drainage Water 2- Effect of Tree Species and Agricultural Drain Locations on Chemical Composition of Some Woody Tree Species

This  study  was  carried out  at  the Kalyobia  Governorate,  for  three  years to study the ability of  four  trees species (Eucalyptus camaldulensis, Salix vemenalis, Morus alba and  Ficus nitida) growing at one side of  the three agricultural  drains (Toukh, Shebine and  Batanda) in addition to Shebine irrigation canal which used as a control treatment for absorption and accumulation of some heavy metals in different trees parts to decrease the pollution rates in agricultural drains. The following data were recorded; Zn, Ni, B, Cr, Cu, Mn and Fe in leaves, branches and roots in all tested tree species at the beginning and ending of study. Results showed that, leaves, branches and roots of Ficus nitida showed significantly increased in Zn content in comparison with the other tree species. Moreover, Morus alba contain the highest values of Cu, Cr and B in leaves, branches and roots as compared to the other tree species. In addtion, Eucalyptus camaldulensis trees contained the highest concentration of Ni during study period. In addition, Salix vemenalis trees significantly augmented of Fe and Mn content in different tested parts in comparison with the other tree species. On other hand, Toukh drain showed the highest concentration of Ni and B during the study period, while Batanda drain contains the highest values of Fe and Ni as compared to the other locations. Also, Shebine drain contains the highest concentration of Mn, Cu and Cr as compared the other treatments.
