Translocation and Bioaccumulation of Trace Metals in Desert Plants of Kuwait Governorates

Abdul H. Bu-Olayan and Bivin V. Thomas    

Abstract: Recent industrialization showed possible trace metals pollution impact in the Kuwait arid ecosystem. Desert plants that were distributed in the six Kuwait Governorate areas representing the residential, industrial and recreational sites (GI-VI) were assessed for trace metals. Observation showed high trace metal concentrations in the sequence of leaves> soil> shoot> root irrespective of the species and areas, respectively. Chrozophora tinctoria showed higher trace metals concentration than the other species. Samples in GII showed high trace metals levels among the six Governorates indicating the significance of pollution due to the recent urban development and rise in population. Metal-wise analysis revealed high metals levels in the sequence of Al (14.16 μg g-1) > Cu (10.71 μg g-1) > Ni (4.83 μg g-1)> Fe (4.60 μg g-1)>Pb (2.89 μg g-1)>V (2.52 μg g-1). Trace metals Translocation Factor (TF) and Bioaccumulation factor (BAF) in all the plants were >1 thus labeling these plants as trace metals accumulators. Pearson’s correlation coefficient on species-wise and metal-wise analysis revealed significance between TF and BAF, respectively. Thus, trace metals sequestration from the soil to these plants characterized them as trace metals pollution indicators.
