Abstract

It was investigated ability of Helichrysum arenarium plant, in phytoextraction, phytostabilization, and phytoremediation in this study. Soil and plant samples were collected from the Demirören alteration site which has the potential of gold mineralization and analyzed for gold and silver. When the results of the analysis were evaluated, it was determined that the gold and silver contents in the soil did not show compatibility with the gold and silver contents of the plants grown at the same point. It was concluded that the high gold and silver concentrations in the plants are related to the hydrothermal alteration and weathering at the point where the plants grow. For investigation of phytoremediation ability of the plant, translocation factor (TF), bio-concentration factor (BCF), and bioaccumulation factor (BAF) were calculated. The values of TF, BAF, and BCF for Ag are equal 0.33, 0.043, and 0.13 and for Au are equal 2.04, 0.59, and 0.29, respectively. So, obtained data show that Helichrysum arenarium is not appropriate for phytoextraction and phytostabilization of gold and silver in this case, but H. arenarium can be used in phyto-mining and for biogeochemical exploration of gold. Considering that the gold and silver concentrations in the developed soil in the study area are low concentrations, it is predicted that a similar study will yield satisfactory-interesting results when it is made in plants grown on the gold mineralization/enrichment areas.

蜡菊(helichryum arenarium)植物对金、银的修复能力:以土耳其Demirören村(g m hane)为例

摘要研究了蜡菊在植物提取、稳定和修复等方面的作用。在具有金矿化潜力的Demirören蚀变点采集土壤和植物样品，进行了金银分析。当对分析结果进行评价时，确定土壤中的金银含量与同一地点生长的植物的金银含量不表现出相容性。结果表明，植物中金、银的高含量与植物生长部位的热液蚀变和风化作用有关。为了研究植物修复能力，计算了植物转运因子(translocation factor, TF)、生物富集因子(bioconcentration factor, BCF)和生物积累因子(bioaccumulation factor, BAF)。Ag的TF、BAF和BCF分别为0.33、0.043和0.13,Au的TF、BAF和BCF分别为2.04、0.59和0.29。由此可见，在这种情况下，砂蜡菊不适合用于植物提取和植物稳定金银，但砂蜡菊可用于植物采矿和金的生物地球化学找矿。考虑到研究区发育土壤中金、银的浓度较低，预测在金矿化/富集区生长的植物上进行类似的研究将会得到令人满意的结果。

期刊介绍： Gold Bulletin is the premier international peer reviewed journal on the latest science, technology and applications of gold. It includes papers on the latest research advances, state-of-the-art reviews, conference reports, book reviews and highlights of patents and scientific literature. Gold Bulletin does not publish manuscripts covering the snthesis of Gold nanoparticles in the presence of plant extracts or other nature-derived extracts. Gold Bulletin has been published over 40 years as a multidisciplinary journal read by chemists, physicists, engineers, metallurgists, materials scientists, biotechnologists, surface scientists, and nanotechnologists amongst others, both within industry and academia. Gold Bulletin is published in Association with the World Gold Council.
