DETERMINATION OF HEAVY METALS CONTENTS IN SOME IMPORTANT MEDICINAL PLANTS COLLECTED FROM DISTRICT KARAK, KHYBER PAKHTUNKHWA, PAKISTAN

摘要: Profile of essential metals (Zn, Fe, Mn, Cu) and non (Cr, Ni, Cd, Pb) in eight medicinally important plants collected from plain area District Karak, Khyber Pakhtunkhwa, Pakistan, was explored through Atomic Absorption Spectrometry. This study aimed to evaluate the concentration heavy medicinal plants. Different showed different concentrations range: 21.42- 75.44 mg/kg for 14.12-41.37 Zn, 15.19-76.89 0.29-6.19 11.11-25.90 Cu, 0.03-0.29 Cr, 0.03-1.31 Cd 1.01-15.30 Pb. High contents Mn Fe were found all Other present low quantity. Accumulation depends upon soil contamination climate locality.
