| 英文摘要 | The long-term effects of decades of open-pit mining at the Bayan Obo deposit, the world's largest light rare earth mine, on the concentrations of several elements in road dust over long distances are unknown. Here, bulk road dust (BRD) and resuspended road dust (RRD) were collected from different distances from the mine for subsequent analysis of mining impacts. As a result of mining activities, light rare earth elements (LREEs), especially La, Ce, Pr and Nd, show different statistical and spatial variations compared to other elements. These LREEs decrease with increasing distance from the mine, and the values found in RRD are higher than those in other particle sizes. Mining emissions and soil have the most significant influence on these LREEs compared to other factors. Spatially, these four LREEs changed significantly over a large area (up to 60 km from the mine) due to mining emissions. However, long-term mining activities affect these elements mainly through mining-contaminated soil as opposed to mining emissions. This study confirms the significant impact of mining activities on LREEs in road dust via a comprehensive data-driven framework, emphasizing the significant environmental effects of long-term open pit mining. |
