“…The food chain structure became smaller due to the elimination of bigger fish and disturbed relations among species. In the river bed system, organic waste accumulates due to decomposer agents' vanishing, and the energy and nutrient transfer cycle are critically low (Ferreira et al, 2021;Gray, 1998;Hogsden & Harding, 2012;Sun et al, 2022). The embryonic stage, growth performance, and reproduction of fish that live in AMD-contaminated water are seriously damaged (Taslima et al, 2022).…”

The coal mining industry is an industrial activity that impacts the environment. This activity will generate acid mine drainage due to the interaction of water, air and sulfide minerals. Acid mine drainage is wastewater with low pH and heavy metals content. These conditions will be given some negatives impact on the environment and human health. The low-cost, applicable and simple method to solve acid mine drainage in mining areas is constructed wetlands. Hence, this paper aims to describe the potential of wetlands as a low-cost and applicable method for acid mine drainage treatment. This paper also describes the holistic information about an overview of constructed wetlands, acid mine drainage (AMD) production and their negative impacts, recent trends in constructed wetlands, recommendation components of wetlands, potential application in rural areas and future considerations

“…Oxidation of reduced inorganic sulfur species and formation of actual acid sulfate soils has an enduring and complex effect on the soil and surrounding environment (Corfield, 2000). This also occurs with mining waste derived from the exploitation of sulfides where these are oxidized to sulfates generating an acid drainage that affects the soil and release large amounts of sulfates and heavy metals into the water (e.g., Costa & Duarte, 2005;Devasahayam, 2006;Ferreira et al, 2020;Jennings et al, 2000;Lin, 1997;Lin & Quvarfort, 1996;Nordstrom, 1982;Pons, 1973). The canals that surround the petrochemical center constitute small ecosystems within a strongly anthropized area.…”

“…Sulfated acid drainage constitutes an environmental problem which is frequently studied in mining waste derived from the exploitation of sulfides (Costa et al, 2008;Costa & Duarte, 2005;Delgado et al, 2019;Devasahayam, 2006;Idaszkin et al, 2017;Jennings et al, 2000;Lecomte et al, 2017;Lin, 1997;Ludwig et al, 2001;Nieto et al, 2013;Nieva et al, 2016Nieva et al, , 2018Nordstrom, 1982;Pons, 1973). In this type of environmental liabilities, sulfides are oxidized to sulfates generating an acid drainage that affects the soil and release large amounts of sulfates and heavy metals into the water (Bigham & Nordstrom, 2000;Ferreira et al, 2020;Konner, 1993;Lin, 1997;Lin & Quvarfort, 1996;Lövgren et al, 1990;Schwertmann & Fitzpatrick, 1993;Turner & Kramer, 1992;Yang et al, 2009). Industries that use sulfur compounds as inputs in production processes (e.g., sulfuric acid production, agriculture, tire or rubber production, animal feed or pyrotechnics, pigment production, steel treatment, batteries production, and insecticides, bleaching paper) can also generate contamination during their storage, as well as generate waste through the discarded material (Tugrul et al, 2003).…”

Environmental liabilities have become one of the most important problems at environmental level, especially those located in urban areas. Within the area of the Río de la Plata coastal plain, industrial waste abandoned by an ancient sulfuric acid industry in a sector of the petrochemical center constitutes an environmental liability composed mainly of fragments of native sulfur. The aim of this work is to evaluate, from laboratory tests, the generation of sulfate acid drainage in environmental liabilities associated with the ancient sulfuric acid industry in order to identify the waste spatial distribution and to determine the impacts that they impart on the quality of the soil and groundwater. The results obtained show that the native sulfur scattered in the environmental liability associated with the ancient sulfuric acid industry constitutes a potential source of sulfated acid drainage that locally affects the soil, groundwater, and underground structures of the industrial center, and also small adjacent ecosystems. The interaction between native sulfur and the rainwater causes the oxidation of the native sulfur releasing protons and sulfates, which reach the groundwater through the infiltration water process, generating the acidification of the environment. The results provide useful draft for the management of environmental liabilities, and also the monitoring data obtained could assist in prioritization of remediation options, which constitute a problem of relevance and whose regulations for management and mitigation are still a controversial issue.

“…AMD pollution leads to high concentrations of SO 4 2− and other sul des in lakes, rivers, and other surface waters, which pose risks to aquatic ecosystems (Jiao et al, 2023). Sulfate accumulation in the surrounding soil also leads to environmental challengers, such as soil hardening and acidi cation, which can in turn negatively affect vegetation growth and crops (Lear et al, 2009;Yuan et al, 2022) as well as the health of the environment and humans (Ferreira et al, 2021;Gao et al, 2019;Neamtiu et al, 2017).…”

The production of acid mine drainage (AMD) involves oxidation of FeS2 to SO42−, during which a variety of intermediate sulfur forms (S2O32−, S0, SnO62−, SO32−) are generated. This study aimed to characterize the spatiotemporal distributions of different forms of these intermediates and their relationships to environmental factors, focusing on an abandoned pyrite mine area. Samples were collected from different water stages and the physicochemical factors were determined on site. High performance liquid chromatography, ion chromatography, and Illumina high-throughput sequencing were used to determine the distributions of iron and sulfur forms and the microbial community structure at each site. Pearson and Spearman correlation were used to analyze the relationships between the distributions of different forms of sulfur and environmental factors during the formation and migration of AMD. The results suggested that SO42− mainly originated from gypsum dissolution and oxidation of the coal mine and FeS2. The dry season was associated with lower water pH and temperature and higher DO and ORP. The maximum correlation coefficient between TFe and SO42− decay was 0.9308, which could be attributed to the formation of sulfate secondary iron-containing minerals. SO42− pollution decreased with increasing migration distance of AMD and showed seasonal variation closely related to precipitation and groundwater flow. The abundance and diversity of microbial community decreased with the production of AMD, mainly acidophilus and sulfur/iron-oxidizing bacteria. Ferrovum occupied an absolute dominant position in weakly acidic samples, and Acidibacter and Sphingomonas were not polluted. Neutral samples include Lachnospiraceae NK4A136 group, Ralstonia, Sinomonas, etc. pH and SO42− showed negative correlations with DO, temperature, and ORP, whereas the dominant strain Acidithiobacillus was positively correlated with SO42−. Increases in water temperature and ORP promoted the transformation of sulfur. The regulation of sulfur conversion to acid is key for developing strategies for preventing and reversing AMD pollution.
