Abstract
The present study was conducted to determine the concentration of heavy metals in some selected medicinal plants in the Shiraz. Heavy metals such as Cd, Pb, Cu, Zn and Fe were investigated in Solanum alatum, Peganum harmala, Achillea, Eryngium, Fumaria officinalis, Artemisia by using Atomic Absorption Spectrometry. Plants showed different metal concentration in the range of: 0.0116-0.079 mg/kg for Cd, 0.024- 0.306 mg/kg for Pb, 3.8- 9.87 mg/kg for Cu, 11.55- 34.19 mg/kg for Zn and 17.94- 187.24 mg/kg for Fe. Health risk assessment showed that consumers are not in danger as far as these metals are concerned. The findings of this study indicated that although most of the sampling plants were contaminated, the estimated daily intake of each metal (EDI) showed that except, Cu in Achillea, Artemisia in children, other samples have EDI below the Acceptable Daily Intakes )ADI) recommended by the Institute of Standards and Industrial Research of Iran and FAO/WHO.
