Author(s): Elham Shirazi-Tehrani* and Amir Peikara
Excessive accumulation of heavy metals in soils, not only leads to environmental pollution but also increases the absorption of heavy metals by plants. The main pathway of human exposure is food consumption. The purpose of this study was to determine the concentration of some heavy metals in Teucrium polium, a native medical plant of the kohgiluyeh region. Samples were prepared by dry digestion method and Cadmium (Cd), Lead (Pb) and Copper (Cu) concentrations were determined using Atomic Absorption Spectrometry (AAS). Our results showed a lower average concentration of Cd than other elements (0.17 ppb). About Cu, the maximum, the minimum, and the mean values were 5 ppm, 1.02 ppb, and 2.75 ppb, respectively. Furthermore, analysis of Pb in T. polium showed the results were appropriate in the range (4.63 ppb). Consequently, it is suggested these tolerant and native plan.. View More»
