Abstract
This study was conducted in Mosul city to assess the level of atmospheric contamination by some of heavy metals (Mn , Zn , Cu , Pb , Fe), five plant species such as Pinusbrutia, Cupressussempervirens, Platanusoccidentalis, Populusnigra and Eucalyptus camaldulensis were selected to study their potential as biomonitor of trace elements, bark and leaves samples were taken through spring and autumn 2011 and from different regions (Ninevah plantation, roadsides, Hammam al Alil, and Cement factory), concentrations of heavy metals were determined by Atomic Absorption Spectrophotometer and the results showed that the concentrations of most of the heavy metals increased in the leaves and bark of roadside sample trees compared to the other locations, Also high concentrations of heavy metals found in spring's samples compared to the autumn samples also high correlation found among most of these heavy metals. These results are important for the development of proper management strategies to decrease atmospheric pollutant by using forest trees.
