Phytoremediation technology is an environmentally friendly purification method that uses plants to clean organic and inorganic contaminants from soil, water, and air. This study aimed to investigate the Evaluation of bioaccumulation indices bioconcentration factor (BCF), bioaccumulation factor (BAF), and translocation factor (TF) in native plants exposed to potentially toxic element contamination at Gamasiab Spring, Nahavand. For this purpose, in September 2025, in the studied area, sampling of aerial tissue (leaves and stems) and subterranean tissue (roots) plant species of Acantholimon olivieri (Jaub. & Spach) Boiss., Artemisia haussknechtii Boiss., Astragalus (Tragacantha) gossypinus Fisch.ex Hoh, Bromus tomentellus Boiss., Plantago lanceolata L., and Verbascum speciosum Schrad., in 4 sites was carried out in the statistical design of completely randomized blocks in three replications. The concentration of cadmium (Cd), chromium (Cr), lead (Pb), manganese (Mn), nickel (Ni), zinc (Zn), in each sample of plants was measured using the device Inductively Coupled Plasma Mass Spectrometry. At each station, the concentration of elements in soil samples was determined. In addition, the values of BCF, BAF, and TF were calculated. The results showed that there was a significant difference between the studied stations in terms of the content of toxic elements in soil samples at a 95% confidence level. The highest concentration of elements related to manganese metal was observed in the aerial tissue (leaves and stems) of Astragalus (Tragacantha) gossypinus with 93.97 mg/kg and the subterranean tissue (roots) of Bromus tomentellus with 30.75 mg/kg, at station 3. The BCF, BAF and TF indices showed that Astragalus (Tragacantha) gossypinus, Acantholimon olivieri and Verbascum speciosum for manganese, nickel, lead and zinc elements, and Artemisia haussknechtii for manganese, nickel and lead elements, with a TF coefficient greater than 1 and a BAF less than 1, had good performance in extracting and transferring elements from their roots to their aerial parts and they have shown good tolerance and adaptation to high metal concentrations. Based on the average content of elements in plant tissues as well as the average calculated values of BCF, BAF, and TF indices for elements, it can be concluded that the species of Astragalus (Tragacantha) gossypinus, Acantholimon olivieri, Verbascum speciosum and Artemisia haussknechtii are suitable for purifying soils contaminated with these elements and can be introduced in similar contaminated areas
