“…There is evidence of environmental pollution due to AMD characterized by low pH, high conductivity, and high concentration of metals from the Pan de Azúcar abandoned mine (lead, silver, zinc) in the Pozuelos basin of Jujuy province, Argentina (Kirschbaum et al, 2012;Murray et al, 2021). This AMD constitutes a severe environmental impact on the nearby areas that are hydrologically connected to the Pan de Azúcar mine (Plaza Caz on et al, 2013;Plaza-Caz on et al, 2021), constituting an anthropogenic source of metals in the Pozuelos basin (Murray et al, 2021). In the last decade, there was also a significant increase in lithium mining activities.…”

The aquatic Andean frogs of genus Telmatobius are one of the most threatened amphibian taxa, with many species having suffered drastic declines and even possible extinction. The Laguna de los Pozuelos' rusted frog Telmatobius rubigo is a fully aquatic species that inhabits lotic systems in the Argentinean vertex of the Lithium Triangle of South America. This study estimated the environmental suitability of an area and geographical distribution of T. rubigo through an ecological niche model. This study also aimed to assess the possible extent of impacts related to mining operations on this threatened species. The ecological niche model of T. rubigo was obtained using specific freshwater habitat variables and the MaxEnt algorithm. The possible extent of impacts related to mining operations was evaluated by overlaying the mining tenure and the estimated distribution of T. rubigo resulting from the model. According to the ecological niche models, T. rubigo could occupy 2,001 km2 in four Argentine basins and three hydrographical units of southern Bolivia and is unlikely to occur in northern Chile. Five environmental variables had the highest contribution to the best selected model: shrub coverture, soil pH, soil organic carbon, and two variables related to the upstream air temperature. The suitable area for T. rubigo overlaps with mining operations by 61.8%. We advise the local communities, governmental environmental agencies, mining companies, and environmental assessors to consider the presence of threatened Telmatobius species in areas subject to mining to protect them and their environment. We encourage incorporating the aquatic Andean frogs as key species into management, environmental monitoring, and remediation plans.

Acid Mine Drainage (AMD) occured after mining activity exposes metal sulphides to oxidizing conditions that impact acidic condition with low pH value in the waters and heavy metals contamination. These conditions are also occurred in abandoned tin mining pits, one of placed in Bangka Belitung Archipelago Province. This mini review aimed to elaborate information of micro- and macro-organism’ life in acid mine drainage to be associated with the possibility of life in abandoned tin mining pits. Acidophilic and acidotolerant organisms such as bacterial, phyto- and zooplankton, and some macroorganism included invertebrate or vertebrate like fishes and also water plants were found in these waters. Their presence developed a symbiosis interaction in aquatic environment. Phytoplankton is an autotroph organism, despite being considered autotroph organism, many phytoplankton require exogenous organic cofactors and nutrients for their life. These cofactors were often served by heterotroph bacterial to sustain the growth of phytoplankton. Instead, bacterial obtained dissolved organic matter derived from phytoplankton to survive in the aquatic environment. Furthermore, phytoplankton was consumed by zooplankton; zooplankton was consumed by small fish to big fish in the waters. In addition, water plants also support the interaction of organisms in the water by supplying dissolved oxygen, also anorganic and organic material for their life. The symbiosis and quorum sensing plays an important role in structuring the aquatic food web and creating a life in the acidic water-polluted heavy metal.

“…The IGCP-707 project had an important role because it enhanced the scientific collaborations among the participants. These publications filled scientific gaps on the topic, bringing important knowledge needed for a comprehensive understanding of the origin, distribution, and biogeochemistry of As in the Altiplano-Puna plateau (Escalera et al, 2020;Murray et al, 2021;Plaza-Cazón et al, 2021;Quino-Lima et al, 2020 a, b;Tapia et al, 2021;2022 a, b, c;Murray et al, 2023). These publications cover a wide range of subjects including geology, geochemistry, environmental sciences, hydrogeology, remediation methods, and human health.…”

Arsenic (As) is one of the most prevalent geogenic trace elements in the groundwater environment that presents a worldwide health concern. In South America, the "Altiplano-Puna" plateau exhibits high As concentrations in water that could be affecting 3 million inhabitants from Argentina, Bolivia, Chile, and Perú. In this As-rich environment with limited water resources, there exists a lack of knowledge regarding the basic geochemistry of As, water quality characterization, and affected population and biodiversity. Between 2020-2022 we performed interdisciplinary research to understand (i) the origin of As, (ii) its geochemistry and mobility, (iii) its distribution in the environment, and (iv) its effects in the local community and unique biodiversity. Our research provides new scientific insights into the biogeochemical cycle of As in the environment and its effect on human health and biodiversity. Our dissemination activities increased the visibility of the As issue for the region that had historically received little attention from the scientific community and local authorities. This project led to additional funding and the creation of a solid research network between the South and North hemispheres, fostering the participation of young researchers, students, and women. An extension of the project was obtained to continue our work during 2023.
