The capability of plant species to accumulate heavy metals in their organs is a factor to alleviate the pollution in the environment. Plants can alleviate environmental pollution using accumulation, uptake and transformation methods, which can change their antioxidant activities. The present study was conducted to investigate Fe and Cu accumulation in root and shoot of Alyssum linifolium, Salvia multicaulis, Muscari neglactum, and Verbascum Thapsus and their antioxidant responses in a Copper mine located in East Azarbaijan. The results showed that the maximum and minimum accumulation of Fe was respectively recorded in the roots of M. neglactum and V. thapsus). In addition, the highest and lowest Cu accumulation was also found in the roots of M. neglactum and V. Thapsus, while there was no significant difference among plant shoots for Fe and Cu. The maximum and minimum SOD and APX activities were observed in M. neglactum and V. Thapsus, respectively, whereas there was no significant difference for MAD among all plant species.
