The migration of arsenic in groundwater is influenced by the heterogeneity of the medium, and the presence of iron minerals adds complexity and uncertainty to this effect. In this study, a stratified heterogeneous sand column with an embedded hematit

Sulfur (S2-) is closely related to the migration and enrichment of arsenic (As) in the water environment, but its mechanism of action in different aqueous medium is still unclear. To determine the adsorption characteristics of As by river sand, a com

The riparian zone is a typical groundwater-surface water interaction zone, and there are few research reports on the behavior of arsenic in this interaction zone under different hydrodynamic conditions. In this study, the river sand samples from the

Once a coal seam has been weathered and oxidized, the quality of the coal is lost and the coal resources are wasted. At the same time, new risks are introduced to the safe operation of the coal mine. Therefore, it is critical to determine the extent

AbstractIn mainland China, approximately 86% of M≥7 earthquakes have occurred in the block boundary zone, which has been well explained by active block theory. However, a few large earthquakes have occurred within the active block, which provides u
