Phytoremediation potentials of some wild plants around the chromium mine

Abstract

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.

Investigation of Heavy Metal Concentrations and Accumulation Capacities of Naturally Growing Species in Old Garbage Area

“…It has been reported that some plant species such as Alyssum murale, Thlaspi vaerulescens, Nicotiana tabacum, Zea mays, Salix viminalis, Helianthus annuus and Viola baoshanensis are used for phytoremediation purposes (Kabata-Pendias, 2011). Similar to this study, in the study conducted by Celiktas (2020), Alyssum oxycarpum species accumulated iron in its roots, stems, and leaves at concentrations close to each other. Although there was no Pb pollution in the area, Alyssum simplex preferred to accumulate the available lead in its roots.…”

“…Although there was no Pb pollution in the area, Alyssum simplex preferred to accumulate the available lead in its roots. Similarly, in a study conducted around Adana Cr mine, Alyssum alyssoides preferred to accumulate lead mostly in its roots (root: 4.86, stem: 1.22, leaf: 3.01, mg kg -1 ) (Celiktas, 2020).…”
