A flooding event caused collapsing of the Stolice flotation tailing dam and spilling of large volumes of sludge into environment. Urgent remediation measures have not been applied due to the lack of financial resources. Remediation values for Sb, Zn, and Pb in the flotation tailing samples were exceeded 20.5, 4.2, and 1.15 times, respectively, emphasizing the need for remediation. Plants growing on mine spoils represent useful tools for environmental monitoring and soil remediation. The appearance of Equisetum ramosissimum as a dominant colonizer on the flotation tailings indicates that biological reclamation of the site is possible. Equisetum ramosissimum shows the ability to phytostabilize and immobilize available fractions of Fe, Mn, Zn, Pb, and Sb. Transfer rate of metals from roots to shoots reveals exclusion of elements from the shoots, preventing their further spreading through the food chain. The results of this study show that E. ramosissimum can be an additional tool for environmental monitoring and remediation of flotation tailings after hazardous events.
洪水事件导致 Stolice 浮选尾矿坝崩塌，大量污泥涌入环境。由于缺乏资金，尚未采取紧急补救措施。浮选尾矿样品中 Sb、Zn 和 Pb 的修复值分别超过 20.5、4.2 和 1.15 倍，强调需要进行修复。生长在矿山废石上的植物是环境监测和土壤修复的有用工具。水龙骨作为浮选尾矿的主要定殖者出现表明，该场地的生物开垦是可能的。水龙骨表现出固定和稳定可用铁、锰、锌、铅和锑的能力。金属从根部向茎部的转移率表明元素从茎部被排斥，防止它们通过食物链进一步扩散。本研究结果表明，在危险事件发生后，水龙骨可以作为浮选尾矿环境监测和修复的附加工具。
