ABSTRACT The phytoremediation is a natural plant for the treatment of heavy metals in soil polluted, which is a few of its kind in the city of Baghdad, where the current study was carried out by collecting three types of plants (Eucalyptus camaldulensis, Dodonaea viscosa and Cynodon dactylon) with soil samples for each region (soil surrounding the plant and far soil). In addition to a control soil sample from the University of Baghdad College of Engineering to identify soil contaminants in public parks and roads with Mercury and choose ten regions (5 regions of Karkh - 5 regions of the Rusafa side) with control, and determine the physical properties pH and soil texture. Results showed that there was a positive correlation between plant type and Mercury absorption in the study areas depending on absorption capacity in three dominant plants respectively: C. dactylon> E. camaldulensis> D. viscosa, (0.44, 0.31 and 0.16) ppm respectively in positive correlation coefficients P values greater than 0.050 (P= 0.46). Soil pH was measured for all studied samples with alkaline ranges (7.35 - 7.8). High pH values in urban soil were due to the high percentage of carbonate, ash and waste from human activity. High pH in irrigation could contribute to alkaline soil increase which in turn leads to restrict the movement of heavy metals, which affect the solubility of soil and retention of minerals was also measured soil texture of the samples studied and showed that most of the soil was sandy loam. Bioconcentration Factor determines the movement of lead from the roots to the aerial parts of the plant. |
