尾矿库影响了附近地下水和土壤中稀土元素的分布和微生物群落。据此，本研究考察了稀土元素在尾矿库周围地下水和土壤中的行为，以及微生物群落的变化。结果表明：尾矿库周围地下水和土壤中稀土元素的富集表现为轻稀土元素富集；通过稀土元素的归一化，地下水中稀土元素的分布模式中Ce和Eu呈现不同程度的由负向正异常，而土壤中Ce和Eu呈现负异常。相关性分析表明，Mn2+、SO42-、Cl-、氨氮和Ca2+与稀土元素的分布呈显著相关。同时，在门水平上，地下水和土壤中的优势菌均为放线菌门、变形菌门和酸杆菌门。这种微生物群落组成与世界各地干旱地区的报道相似。另一方面，芽孢杆菌和芽球菌在属水平上与稀土元素有显著的相关性。本研究可为环境中稀土元素的风险评价提供重要依据。
The distribution of rare earth elements and the microbial community in nearby ground water and soil were influenced by tailings ponds. Accordingly, the behaviors of rare earth elements in ground water and soil around the tailings pond, and the changes of microbial communities were both investigated in this study. The results showed that rare earth elements accumulated in ground water and soil around the tailings pond appeared as light rare earth elements enrichment. Through the normalization of rare earth elements, different extents of anomaly (from negative to positive) were observed for Ce and Eu in the distribution patterns of REEs in groundwater, however, Ce and Eu were negatively anomaly in soil. According to the correlation analysis, Mn2+, SO42-, Cl-, ammonia nitrogen and Ca2+ are significantly correlated with the distribution of rare earth elements. Meanwhile, there were the same dominant bacteria in ground water and soil including Actinobateria, Proteobacteria and Acidobacteria at the phylum level. This microbial community composition is similar to that reported in arid lands around the world. On the other hand, Bacillus and Blastococcus showed significant correlation with rare earth elements at the genus level. This study might provide an important basis for the risk assessment of REEs in the environment.
