“…Notably, the retention efficiency for H + ions in the soil 0 –10cm samples reached 2270.41 times more than in the soil 10 –20cm samples in treatment 3 (66 mL AMD/application). Yang et al [5] studied the variation of pH in paddy red soil profiles along the Hengshi River that have been polluted by AMD from the Dabaoshan mining area in South China and found that the pH slightly increased from 4.75 in the soil at a 0–10 cm depth, and to 5.00 in the soil at a 10–20 cm depth. Thus, compared to that in the red soil, the interception of H + in calcareous soil exhibits more distinct “layering”.…”

“…When CaCO 3 dissolves under the influence of H + ions, Ca 2+ migrates downward and combines with SO 4 2− during the migration process, which causes elemental S to move further downward than Fe in calcareous soil that has been contaminated by AMD. Yang et al [5] found that SO 4 2− can react with Fe oxides/hydroxides under acidic conditions in red paddy soil. In the current study of calcareous soil, the SO 4 2− that was retained by Fe oxides/hydroxides was not significant because the elemental S and elemental Fe migration rates were not similar.…”

“…On the one hand, the industry produces economic benefits, however on the other hand, it causes serious contamination to the environment [4]. The environmental issues around mining areas are primarily related to mining-related surface disturbance [5], tailings waste pile production [6], dust pollution [7], and acid mine drainage (AMD) [8]. …”

“…Inadequately treated AMD is a very widespread environmental problem that directly affects the healthy development of the mining industry [13]. Many researchers have studied environmental problems in soil and aquatic ecosystems that have arisen from acid mine drainage in China and elsewhere [5,14,15,16,17,18]. In fact, soil that has been polluted by iron and sulfate has attracted extensive attention around the world.…”

“…Therefore, the issue of cultivated land quality has always been very topical in China [23]. Unfortunately, in China, some farmland that is surrounded by mining areas has been severely polluted by AMD [3,5,14,24]. Therefore, it is important to accurately identify the migration behavior of AMD pollutants in Chinese soils.…”

As a major province of mineral resources in China, Shanxi currently has 6000 mines of various types, and acid mine drainage (AMD) is a major pollutant from the mining industry. Calcareous soil is dominant in western North China (including the Shanxi Province), therefore, clarifying the migration behavior of the main AMD pollutants (H+, S, Fe, heavy metals) in calcareous soil is essential for remediating AMD-contaminated soil in North China. In this study, the migration behavior of the main pollutants from AMD in calcareous soil was investigated using soil columns containing 20 cm of surficial soil to which different volumes of simulated AMD were added in 20 applications. Filtrate that was discharged from the soil columns and the soil samples from the columns were analyzed. Almost all of the Fe ions (>99%) from the AMD were intercepted in the 0–20 cm depth of the soil. Although >80% of SO42− was retained, the retention efficiency of the soil for SO42− was lower than it was for Fe. Cu, as a representative of heavy metals that are contained in AMD, was nearly totally retained by the calcareous soil. However, Cu had a tendency to migrate downward with the gradual acidification of the upper soil. In addition, CaCO3 was transformed into CaSO4 in AMD-contaminated soil. The outcomes of this study are valuable for understanding the pollution of calcareous soil by AMD and can provide key parameters for remediating AMD-contaminated soil.

Land subsidence is a serious geological event, and can trigger severe environmental and ecological issues. In this study, the influences of coalmining subsidence on distribution of farmland microbiomes and their functional genes were investigated by 16 S ribosomal RNA (rRNA) gene and metagenome sequencing. The results showed the existence of a core microbiome, which determined the community compositions across the subsidence farmland. Subsidence decreased the relative abundances of dominant Streptomyces, Nocardioides, and Rhizophagus, but increased the relative abundances of dominant Bradyrhizobium, Rhizobium, and Trichoderma. Subsidence also decreased the relative abundances of genes related to carbon metabolism, Quorum sensing, aminoacyl-transfer RNA (tRNA) biosynthesis, and oxidative phosphorylation, and increased the relative abundances of genes related to two-component system and bacterial chemotaxis. Furthermore, subsidence weakened the biosynthesis of organic carbons by decreasing the relative abundances of genes encoding glycosyl transferases, and strengthened decomposition of degradable organic carbons of the microbiomes and auxiliary activities by increasing the relative abundances of genes encoding glycoside hydrolases and polysaccharide lyases.The concentrations of total phosphorus, Mg 2+ , and Ca 2+ at the lower areas were significantly higher than those at the upper areas, indicating an associated loss of soil nutrients. Canonical correspondence analysis showed that soil moisture, pH, and the concentrations of NH 4 + and Ca 2+ were the main factors affecting the distribution of the microbiomes and their functional genes. Collectively, this study shows that coal-mining subsidence alters soil
