Abstract
Heavy metals such as Cr, Fe, Zn, Mn, Ni, Pb, Cu and Cd, and inorganic ions like HCO3(-), CO32-, Ca2+, Mg2+, Cl-, Na+, SO42-, NO3-, Fe2+ and F- were investigated in medicinally important plants: Taraxacam officinale, Cichorium intybus and Figonia critica, applying atomic absorption spectrophotometer techniques. In the studied herbs, there were variable amounts of heavy metals and inorganic ions. The purpose of this study was to standardize heavy metals contamination in various indigenous medicinal plants and to create awareness among the public regarding its safe use at collection areas (containing high level of heavy metals) and their adverse health effects.
