Each newly-created pond which is supplied with mine water gives the opportunity to study a unique ecosystem in context of possible conditions for biotic live. Therefore, this research aimed to assess a phytoplankton-based ecological potential against the trophic conditions and the risk of contamination with trace elements, and demonstrate the possibility to stabilize at least good water quality of a clarification pond. The gradual decrease in turbidity-related variables (including suspended solids and iron) and nutrients, on the one hand, and an increase in phytoplankton-related indicators, on the other hand, were the most evident. Besides, relative stability in trace elements (the best water quality class), trophic level (slightly eutrophic level) and ecological potential (maximum potential), and relative instability in sulfates and calcium were also recorded. The final stabilization of water habitat resulted in abundant growth of charophyte Nitella mucronata. This all suggested a new ecological opportunity for settlement of a rare species and important for biodiversity enhancement. Furthermore, the study revealed that a clarification pond did not pose any toxic risk from the elevated content of trace elements or the growth of toxic or potentially toxic cyanobacteria which is essential for proper functioning and management of water ecosystems.
每个新创建的矿水池塘都为研究生物生存的可能条件下的独特生态系统提供了机会。因此，本研究旨在评估浮游植物的生态潜力，以及池塘富营养化和微量元素污染的风险，并证明稳定澄清池至少良好水质的可能性。最明显的是浊度相关变量（包括悬浮物和铁）和营养物质的逐渐减少，另一方面是浮游植物相关指标的增加。此外，微量元素（最佳水质类别）、营养水平（轻度富营养化水平）和生态潜力（最大潜力）相对稳定，硫酸盐和钙相对不稳定。水栖息地的最终稳定导致了 charophyte Nitella mucronata 的大量生长。这一切都为稀有物种的定居和生物多样性的增强提供了新的生态机会。此外，该研究还表明，澄清池不会因微量元素含量升高或有毒或潜在有毒蓝藻的生长而产生任何毒性风险，这对水生态系统的正常运行和管理至关重要。
