摘要

采用电感耦合等离子体发射光谱法(ICP-OES)研究了保加利亚东Rodope前矿区(再生尾矿库)土壤和不同植物物种中的稀土元素。这个尾矿库是20年前开垦的。该研究工作旨在确定再生尾矿库中天然存在的植物开采稀土元素的潜力。在土壤样品中，铈(Ce)、镧(La)和钆(Gd)的含量超过了土壤中元素的平均含量。计算生物浓缩系数(BCF)。结果表明，轻稀土元素(lree)在植物样品中的含量高于重稀土元素(hree)。

Potential for Phytomining of Rare Earth Elements by Naturally Occurring Plants in Reclaimed Tailing Ponds

Rare earth elements (REEs) from the ex-mining area (reclaimed tailing ponds) in East Rodope, Bulgaria, were investigated in soil and different plant species using inductively coupled plasma-optical emission spectrometry (ICP-OES). The tailings pond was reclaimed 20 years ago. The research work aims to determine the potential for phytomining of rare earth elements by naturally occurring plants in reclaimed tailing ponds. In the soil samples, the concentrations of cerium (Ce), lanthanum (La), and gadolinium (Gd) exceeded the average content of the elements in soils. The bioconcentration factor (BCF) was calculated. It was found that light rare earth elements (LREEs) are in greater concentration in plant samples than heavy rare earth elements (HREEs).

期刊介绍： The International Journal of Conservation Science (IJCS) is a high quality peer-reviewed journal devoted to the publication of original research papers in applied conservation science and its broad range of applications. IJCS it is an open access journal. All content is freely available without charge to any user or his/her institution. Users are allowed to read, download, copy, distribute, print, search, or link to the full texts of the articles in this journal without asking prior permission from the publisher or the author. The topics cover all disciplines and branches of modern scientific conservation, including different aspects on general conservation theory, scientific investigation of works of art, authentication, determination of conservation state, compatibility studies for preservation and restoration procedures and monitoring of interventions effectiveness, etiopathology of historic and natural monuments, studies on the mechanisms of deterioration and degradation for different materials as structural and ornamental elements, impact of the environmental factors or agents on monuments and ecosystems, obtaining and characterization of new materials and procedures for preservation and restoration, new methodologies for scientific investigation, cross-related problems concerning research applied to conservation science, biodiversity conservation. Review articles in selected areas are published from time to time.
