“…Besides active mines, abandoned mines are also a significant threat to health as direct exposure to acid mine drainage discharged from abandoned metal mines can affect aquatic biota and human health (Tomiyama & Igarashi, 2022). Since minerals play a vital role in many areas, they cannot be entirely avoided.…”

“…Mining activities are among the most significant sources of heavy metal pollution (MEP of China, 2014), with mine tailings a critical contamination factor of heavy metals (Ganhurrel et al, 2020;Mezned et al, 2022). Heavy metals derived from mined areas may cause adverse effects on the ecological environment and the health of residents because they enter and accumulate in the soil and are then transported downward to diffuse into groundwater (Lee et al, 2005;Doya et al, 2020;Zhu et al, 2021;Tomiyama and Igarashi, 2022). China is one of the largest global producers and consumers of metals/metalloids such as antimony (Sb), iron (Fe), lead (Pb), manganese (Mn), and zinc (Zn) (Gunson and Jian, 2001).…”

China holds large-scale lead–zinc mineral resources; however, mining activities often cause severe contamination by heavy metals. This study systemically assessed contamination by eight heavy metals (Cu, Zn, Cd, Pb, Cr, Hg, Ni, and As) in mine tailings, soil, and groundwater from 27 contaminated sites across China. Regarding mine tailings, 1% of the mine tailing samples were hazardous waste and 20% were class II non-hazardous waste. Regarding soil, Zn and Pb showed the highest mean concentrations, at 5574.67 mg/kg and 2034.88 mg/kg, respectively. The indexes of geo-accumulation (Igeo) of eight heavy metals ranged from −3.62 to 7.67, while Zn, Pb, and Cd showed the highest environmental risk levels as the priority pollutants. The contamination levels of these heavy metals in groundwater were generally in the order of Zn>As>Pb>Ni>Cd>Cu>Hg>Cr. In this study, 20% of the soil and 10% of the groundwater samples exceeded the corresponding quality limits. The content of heavy metals in soil, groundwater, and mine tailing were positively correlated, demonstrating the main pollution source and transport paths. The pollution levels of heavy metals in soil and groundwater were listed in the foremost and moderate positions compared with similar sites from other countries, respectively. These results may help determine the pollution levels of lead–zinc mining regions and direct the remediation activities of target sites to support the environmental management of abandoned mining and tailing waste in China.

“…The pollution of groundwater by human activities has been paid more and more attention [1]. Mine production activities disturb groundwater and cause groundwater pollution [2][3][4][5][6][7][8]. The oxidation of sulfide minerals in waste-rock storage facilities, tailings storage facilities, and abandoned or active mine structures leads to the generation of acid mine drainage (AMD).…”

The waste rock produced by mining in Copper mine has high sulfur content, which leads to the risk of acidic water pollution to the downstream groundwater and soil environment. Based on the pollution prevention and control ideas of source control and process control, the groundwater barrier project of vertical and horizontal seepage prevention is implemented for acid reservoirs. Through the comparison of groundwater monitoring data from upstream and downstream of the vertical barrier, it is found that the acid pollution of the water in the downstream of the barrier is significantly improved compared with upstream of the barrier, and the concentration of heavy metals and other characteristic pollutants is significantly reduced.
