Comparison of UAS and Sentinel-2 Multispectral Imagery for Water Quality Monitoring: A Case Study for Acid Mine Drainage Affected Areas (SW Spain)
Isgró, Melisa A.; Basallote Sánchez, María Dolores
; Caballero, Isabel; Barbero, Luis (MDPI, 2022-08)
Uncrewed Aerial Systems (UAS) and satellites are used for monitoring and assessing the quality of surface waters. Combining both sensors in a joint tool may scale local water quality retrieval models to regional and global ... -
Distribution and availability of rare earth elements and trace elements in the estuarine waters of the Ría of Huelva (SW Spain)
Ruiz Cánovas, Carlos; Basallote Sánchez, María Dolores; Macías Suárez, Francisco (Elsevier, 2020-08)
Metal pollution in estuaries represents a serious environmental challenge, especially in areas affected by industrial and mining activities. This study investigates the metal partitioning and availability of rare earth ... -
Effects of estuarine water mixing on the mobility of trace elements in acid mine drainage leachates
Pérez López, Rafael; Millán Becerro, Ricardo; Basallote Sánchez, María Dolores; Carrero Romero, Sergio; Parviainen, Annika; Freydier, Rémi; Macías Suárez, Francisco; Ruiz Cánovas, Carlos (Elsevier, 2023)
This research reports the effects of pH increase on contaminant mobility in acid mine drainage from the Iberian Pyrite Belt by seawater mixing in the laboratory, simulating the processes occurring in the Estuary of Huelva ... -
Geochemical behaviour and transport of technology critical metals (TCMs) by the Tinto River (SW Spain) to the Atlantic Ocean
Ruiz Cánovas, Carlos; Basallote Sánchez, María Dolores; Macías Suárez, Francisco; Olías Álvarez, Manuel; Pérez López, Rafael; Ayora, Carlos; Nieto Liñán, José Miguel (Elsevier, 2021-04)
This paper addresses the behaviour of several technology critical metals (TCMs), i.e., rare earth elements (REEs), Y, Sc, Ga and Tl, in the Tinto River (SW Spain), quantifying their fluxes to the Atlantic Ocean and unravelling ... -
Metal mobility and bioaccessibility from cyanide leaching heaps in a historical mine site
Ruiz Cánovas, Carlos; Moreno González, Raúl; Vieira, Bruno J. C.; Waerenborgh, João Carlos; Marques, Rosa; Macías Suárez, Francisco; Basallote Sánchez, María Dolores; Olías Álvarez, Manuel; Prudencio, María Isabel (Elsevier, 2023-02)
Unlike acidic sulfide mine wastes, where metal/loid mobility and bioaccessibility has been widely studied, less attention has been paid to alkaline cyanide heap leaching wastes. Thus, the main goal of this study is to ... -
Metal(loid) release from sulfide-rich wastes to the environment: The case of the Iberian Pyrite Belt (SW Spain)
Ruiz Cánovas, Carlos; Macías Suárez, Francisco; Basallote Sánchez, María Dolores; Olías Álvarez, Manuel; Nieto Liñán, José Miguel; Pérez López, Rafael (Elsevier, 2021)
Sulfide-mining wastes may lead to severe environmental and human health risks, especially challenging in abandoned mines without environmental regulation. This work is aimed at discussing the environmental problems associated ... -
Mineral reactivity in sulphide mine wastes: influence of mineralogy and grain size on metal release
Ruiz Cánovas, Carlos; González de la Aleja Pérez, Carolina; Macías Suárez, Francisco; Pérez López, Rafael; Basallote Sánchez, María Dolores; Olías Álvarez, Manuel; Nieto Liñán, José Miguel (Copernicus Publications, 2019)
The aqueous oxidation of sulphide minerals leads to the generation of acid mine drainage (AMD), one of the main causes of water pollution worldwide. Mineral reactivity is greatly enhanced as a result of extraction and ... -
Review of the concentration, bioaccumulation, and effects of lanthanides in marine systems
Neira, Patricia; Romero Freire, Ana; Basallote Sánchez, María Dolores; Qiu, Hao; Cobelo García, Antonio; Ruiz Cánovas, Carlos (Frontiers Media SA, 2022-07-28)
Rare earth elements (REEs) or lanthanides are often found together in nature, and they are used in multiple anthropogenic activities from green energy and medical technologies to telecommunications and defense systems. ... -
Stream-pit lake interactions in an abandoned mining area affected by acid drainage
Fuentes López, José María; Olías Álvarez, Manuel; León, Rafael; Basallote Sánchez, María Dolores; Macías Suárez, Francisco; Moreno González, Raúl; Ruiz Cánovas, Carlos (2022)
Opencast mining of sulfide ore deposits may lead to the formation of anthropogenic acidic lakes with highly polluted waters. In these systems, it is crucial to understand the hydrological connections between surface and ... -
Surface and Groundwater Quality Evolution in the Agrio and Guadiamar Rivers After the Aznalcóllar Mine Spill (SW Spain): Lessons Learned
Olías Álvarez, Manuel; Ruiz Cánovas, Carlos; Basallote Sánchez, María Dolores (Springer, 2020-09)
The failure of the tailing dam at the Aznalcóllar mine (SW Spain) in 1998 released ≈ 6 million m3 of pyrite sludge and acidic waters, and caused an enormous environmental disaster in the Agrio and Guadiamar rivers. A small ... -
Thallium distribution in an estuary affected by acid mine drainage (AMD): The Ría de Huelva estuary (SW Spain)
Ruiz Cánovas, Carlos; Basallote Sánchez, María Dolores; Macías Suárez, Francisco; Freydier, Rèmi; Parviainen, Annika; Pérez López, Rafael (Elsevier, 2022)
This study investigates the behavior of Tl in the Ría de Huelva (SW Spain), one of the most metal polluted estuaries in the world. Dissolved Tl concentration displayed a general decrease across the estuary during the dry ... -
Thallium in environmental compartments affected by acid mine drainage (AMD) from the Iberian Pyrite Belt (IPB): From rocks to the ocean
Ruiz Cánovas, Carlos; Basallote Sánchez, María Dolores; Macías Suárez, Francisco; Olías Álvarez, Manuel; Pérez López, Rafael; Nieto Liñán, José Miguel (Elsevier, 2022)
This works investigates the origin, behavior and fate of Tl in acid mine drainage (AMD) affected areas at catchment scale, following the path from rocks to the ocean. To address this issue, comprehensive data set of Tl in ... -
The Evolution of Pollutant Concentrations in a River Severely Affected by Acid Mine Drainage: Río Tinto (SW Spain)
Olías Álvarez, Manuel; Ruiz Cánovas, Carlos; Macías Suárez, Francisco; Basallote Sánchez, María Dolores; Nieto Liñán, José Miguel (MDPI, 2020-06)
The Río Tinto, located in the Iberian Pyrite Belt (SW Spain), constitutes an extreme case of pollution by acid mine drainage. Mining in the area dates back to the Copper Age, although large-scale mining of massive sulfide ... -
