Abstract The heavy metal concentration in plant tissues of Ranunculus ficaria, Plantago major, Taraxacum officinale, and Achillea millefolium, frequently consumed or used in traditional medicine, collected from one of radioactive area of Romania, not been previously reported by any research group. The content of Cr, Mn, Ni, Cu, Zn, Cd, Pb were determined by ICP-MS. To evaluate the level of pollution, the plants are examined to determine the EDI, HRI and TTHQ values, to reach a judgment about whether their consumption is risky or not in terms of human health. The high amounts of Cd, Mn and Pb, in tissues of Taraxacum officinale and Plantago major, lead to the fact that the ecosystem in which these species are growing should be evaluated by the authorities

in terms of environmental pollution. DIM and HRI data showed that A. millefiori and R. ficaria can be safely used by locals, while T. officinale and P. major are thought to pose a risk in terms of heavy metals. Accumulation of metals by both roots and leaves in T. officinale and P. major was proportional to the metal concentration in the tailings dumps, while Cr, Mn, Cd, and Pb content exceeded the maximum permissible daily levels.
