Phytoremediation potential of wild plants in the territory of a gold mining enterprise
Relevance. Phytoremediation is the most relevant and popular method of soil purification from pollution. However, in addition to the ability of plants to accumulate metals, it is necessary to take into account their adaptability to growing conditions. Therefore, information on native plant species with wide adaptability is important. Screening of plants in metal-bearing areas will help identify plant species that are optimal for phytoremediation. Aim. To study the accumulation capacity of plants growing on the territory of the mining enterprise JSC Pokrovsky Rudnik (Pioner gold deposit, Amur Region) in relation to polluting elements. Methods. The elemental composition of soils, grounds, plants and the content of mobile forms of soils were determined using atomic emission and mass spectral methods. Results. The authors have identified the following pollutant elements: As, S, Mn, Cr, Co, Ni, Cu, Zn, Mo, Cd, Sb, Te, W, Pb, Bi, requiring closer attention in the territory of the mining enterprise of JSC Pokrovsky Rudnik. The predominant pollutant is As. The ability of native plant species to enrichment was studied using accumulation factors and the actual biogeochemical mobility of elements. As a result of the correlation analysis between the content of elements in plant samples and their mobile forms in soils, it was found that plants growing on technogenically transformed soils have barrier mechanisms for the absorption of As, Sb, Pb, Bi, Co, Cr, Ni and Cu. A number of plant species were identified as potential remediants of contaminated soils in the territory of the mining complex, due to their ability to accumulate toxic elements without damaging their normal physiological state, adaptation to the harsh climate of the region, and altered soil conditions.
