Dianthus sylvestris subsp. sylvestris as a promising candidate for phytostabilization of copper-contaminated post-mining sites in Alpine ecosystems

The lack of remediation of inactive mine sites is a serious global concern, as they pose risks to the environment, human health, and safety. The potential of Dianthus sylvestris subsp. sylvestris to remediate post-mining sites contaminated with copper (Cu) at high altitudes, which is a challenging task for most management strategies, was explored in this study. More than 1300 mg Cu kg-1 in shoots were found in plants collected at the Monte Avanza legacy mine site (Alps). However, it is unclear whether this is due to hyperaccumulation or foliar contamination. To address this gap, field samples were washed with two different protocols, and a controlled Cu-tolerance test was conducted. While very high Cu concentrations, exceeding the Cu hyperaccumulation threshold of 300 mg kg-1, were found in samples washed with water, results for the plants cleaned with a more rigorous approach with EDTA suggested Cu exclusion strategy. Under controlled conditions, the plant showed Cu hypertolerance but ..., Plant specimens of Dianthus sylvestris subsp. sylvestris (roots, shoots, flowers, and seeds) and respective soil samples collected on the site (Monte Avanza, IT).

The study investigates the necessity of cleaning the field samples with a stringent solution instead of simple water prior to metal analysis. The study also investigates the potential of *D. sylvestris* subsp. *sylvestris* for remediating copper-contaminated post-mining sites at high altitudes, finding that the plant exhibits a copper exclusion strategy rather than hyperaccumulation. Consequently, *D. sylvestris* subsp. *sylvestris* presents as a promising candidate for copper phytostabilization at high-altitude legacy mine sites, emphasizing the importance of controlled experiments when evaluating phytoremediation potential. ## Description of the data and file structure The data are soil and plant copper (Cu) conc...废弃矿山场地未得到有效修复是一项严峻的全球性议题，因其对生态环境、人类健康及公共安全均构成潜在威胁。本研究聚焦高海拔铜（Cu）污染采矿后遗迹场地的修复潜力，这类场地的治理对多数现有管理策略而言均极具挑战性，研究对象为林石竹原亚种（Dianthus sylvestris subsp. sylvestris）。 研究团队在阿尔卑斯山脉蒙特阿万扎遗留矿山场地采集的植株地上部分中，检测到铜含量超过1300 mg·kg⁻¹。然而目前尚不清楚该高铜含量源于铜超富集作用还是叶片表面的铜污染。为填补这一研究空白，本研究采用两种不同清洗方案对野外采集样品进行处理，并开展了受控铜耐受性试验。经清水清洗的样品中检测到极高铜浓度，远超300 mg·kg⁻¹的铜超富集阈值；而采用更严苛的乙二胺四乙酸（EDTA）清洗方案处理的植株样品结果则表明，该植物采取铜排阻策略。在受控培养条件下，该植物表现出铜超耐受性，但…… 本研究采集了蒙特阿万扎（意大利）场地的林石竹原亚种植株样品（根、地上部分、花及种子）及其对应的土壤样品。 林石竹原亚种被置于受控条件下进行水培培养。 样品数据通过电感耦合等离子体光发射光谱仪（Inductively Coupled Plasma Optical Emission Spectrometer，简称ICP-OES）与直尺完成测定，数据可通过Microsoft Excel或其他电子表格编辑器（例如免费开源的Apache OpenOffice Calc）进行整理分析。 # 铜植物稳定化：林石竹原亚种（Dianthus sylvestris subsp. sylvestris）的铜浓度与根系生长 *** 本数据集对应研究论文《林石竹原亚种（Dianthus sylvestris subsp. sylvestris）：阿尔卑斯生态系统铜污染采矿后遗迹场地植物稳定修复的潜在候选物种》。本研究旨在探究两大核心问题：一是在金属元素分析前，采用严苛清洗液而非清水处理野外采集样品的必要性；二是验证林石竹原亚种对高海拔铜污染采矿后遗迹场地的修复潜力。研究结果表明，该植物采取铜排阻策略而非铜超富集策略。因此，林石竹原亚种可作为高海拔遗留矿山场地铜污染植物稳定修复的潜在候选物种，本研究同时强调了在评估植物修复潜力时开展受控试验的重要性。 ## 数据与文件结构说明 本数据集包含土壤与植物的铜（Cu）浓度……
