Abstract

Vanadium mining leads to increasing environmental release of vanadium, posing ecological and health risks. are a recognized source of microplastic pollution, making tailings ponds emerging hotspots for microplastic and vanadium coexistence. Vanadium adsorption alters the physicochemical properties of microplastic surfaces, affecting plastisphere microbiome composition and function. It remains unclear how the plastisphere microbiome responds to vanadium stress and the resulting ecological risks. This study aims to investigate the selective enrichment of microbial communities and functions within the plastisphere of tailings pond adjacent to a large-scale vanadium mine. The results reveal plastisphere assemblages with lower diversity but higher functional specialization than surrounding matrices, enriched in vanadium resistant and plastic degrading taxa (Streptomyces, Hydrogenophaga and Delftia). Deterministic processes dominated plastisphere community assembly, driven by environmental filtering from vanadium and co-occurring metals. Functional profiling indicated enhanced aromatic compound degradation and potential pathogenicity genes in the plastisphere, whereas the sediment plastisphere exhibited reduced nitrogen cycling functions, suggesting altered biogeochemical processes and ecological risks. Our findings underscore the scientific value of the plastisphere as a unique ecological niche that reshapes microbial functions, highlighting its critical role in assessing the ecological risks of mining pollution and informing targeted bioremediation strategies.

尾矿库生态系统钒压力下塑性圈微生物群落及其功能的选择性富集

钒开采导致钒的环境释放增加，造成生态和健康风险。是公认的微塑料污染源，使得尾矿库成为微塑料与钒共存的热点。钒的吸附改变了微塑料表面的物理化学性质，影响了塑料球微生物组的组成和功能。目前尚不清楚塑性球微生物组如何对钒胁迫和由此产生的生态风险作出反应。本研究旨在探讨某大型钒矿尾矿库塑性圈内微生物群落及其功能的选择性富集。结果表明，与周围基质相比，塑料球组合的多样性较低，但功能专门化程度较高，富含抗钒和塑料降解类群（链霉菌、食氢菌和Delftia）。确定性过程主导了塑料圈群落的组装，由钒和共生金属的环境过滤驱动。功能分析表明，在塑料圈中芳香族化合物降解和潜在的致病基因增强，而沉积物塑料圈表现出氮循环功能减弱，表明生物地球化学过程和生态风险发生了改变。我们的研究结果强调了塑料圈作为重塑微生物功能的独特生态位的科学价值，强调了其在评估采矿污染的生态风险和提供有针对性的生物修复策略方面的关键作用。

期刊介绍： Environmental Pollution is an international peer-reviewed journal that publishes high-quality research papers and review articles covering all aspects of environmental pollution and its impacts on ecosystems and human health. Subject areas include, but are not limited to: • Sources and occurrences of pollutants that are clearly defined and measured in environmental compartments, food and food-related items, and human bodies; • Interlinks between contaminant exposure and biological, ecological, and human health effects, including those of climate change; • Contaminants of emerging concerns (including but not limited to antibiotic resistant microorganisms or genes, microplastics/nanoplastics, electronic wastes, light, and noise) and/or their biological, ecological, or human health effects; • Laboratory and field studies on the remediation/mitigation of environmental pollution via new techniques and with clear links to biological, ecological, or human health effects; • Modeling of pollution processes, patterns, or trends that is of clear environmental and/or human health interest; • New techniques that measure and examine environmental occurrences, transport, behavior, and effects of pollutants within the environment or the laboratory, provided that they can be clearly used to address problems within regional or global environmental compartments.
