Phytoremediation potentials of some wild plants around the chromium mine


 Phytoremediation is the general name of techniques that uses plants to remediate polluted environments. Heavy metals are one of the pollution resources caused by anthropogenic or natural ways. In this study, it was aimed to find new plant species for phytoremediation of heavy metals. For this purpose, field researches were done in chromium mining sites. After that, plants were selected, which were relatively abundant in the mining sites. Aethionema spicatum, Alyssum alyssoides, Alyssum floribundum, Alyssum oxycarpum, Thlaspi oxyceras, Convolvulus compactus, Onosma cappadocica and Salvia multicaulis were researched. For understanding phytoremediation potentials of plants, heavy metal analyses (Cr, Ni, Co, Pb, Zn, Mn, Cu and Fe) were done in rhizosphere soils and different parts of plants. Then plants were evaluated for accumulation and translocation of heavy metals by using BCF and TF calculations. Aethionema spicatum, Alyssum floribundum, Alyssum oxycarpum and Thlaspi oxyceras were found as hyperaccumulators for Ni because of their metal accumulation abilities.
