Study of heavy metals including Fe, Zn, Mn, Ni, Cr, Cd and Pb in Albizia lebbeck collected from different environmental sites i.e. industrial site, heavy traffic site, residential site and non residential site of Khyber Pakhtunkhwa, Pakistan was performed by Atomic Absorption Spectrometry. Dry digestion method was applied for the digestion of plant samples. Highest level of Fe (45.10 ppm), Zn (31.25 ppm) and Mn (23.89 ppm) were recorded in plant samples collected from non residential area while high concentration of Ni (5.08 ppm), Cr(1.10 ppm), and Cd (0.41 ppm) were found in plant samples collected from industrial area and lead content was high (12.19 ppm) in sample of heavy traffic site. The results shows that the accumulation of heavy metals in medicinal plants depends upon the climate of locality, air pollution, soil contamination and other environmental factors where the plants grow. The implication of the investigation was to make attentiveness among the community about the utilization of Albizia lebbeck containing high level of heavy metals and their adverse toxic effects.
