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 high trace metals concentration than other species. Samples in G-II showed high trace metals levels among the six Governorates indicating the significance of pollution due to the recent urban development. Metal-wise analysis revealed high metals levels in the sequence of Al (14.16 mu g g(-1)) > Cu (10.71 mu g(-1)) > Ni (4.83 mu g g(-1))> Fe (4.60 mu g g(-1))>Pb (2.89 mu g g(-1))>V (2.52 mu g 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.
