The urgent need to minimize the potential harm deriving from global climate change and ocean acidification has led governmental decision-makers scientists explore study new strategies for reducing levels of anthropogenic CO2. One mitigation measures proposed concentration atmospheric CO2 is capture storage this gas in subseabed geological formations; proposal generating considerable international interest. main risk associated with option leakage retained CO2, which could cause serious...
Rare earth elements (REEs) or lanthanides are often found together in nature, and they used multiple anthropogenic activities from green energy medical technologies to telecommunications defense systems. However, the current understanding on concentration behavior of REEs oceans marine organisms is limited, no regulatory information limits have been settled. Here, we present a review concentrations waters biota. reach aquatic ecosystems mainly by continental contributions, maximum reported...
Carbon capture and storage is increasingly being considered one of the most efficient approaches to mitigate increase CO2 in atmosphere associated with anthropogenic emissions. However, environmental effects potential leaks remain largely unknown. The amphipod Ampelisca brevicornis was exposed sediments collected different areas Gulf Cádiz subjected several pH treatments study CO2-induced acidification on sediment toxicity. After 10 days exposure, results obtained indicated that high lethal...
It has been estimated that the acid mine drainage (AMD) impacted Odiel river basin in southern Spain supplies 0.37% and 15% of global riverine fluxes Cd Zn to oceans, respectively (Sarmiento et al., 2009). However, behaviour Ria Huelva estuary, which connects Tinto watersheds with Gulf Cadiz, yet be fully investigated. Furthermore, very few studies have investigated isotope estuaries worldwide. This study presents concentrations isotopic compositions for estuary surrounding watersheds,...
Abstract The Doñana Natural Space (SW Spain) is considered one of the most important European wetlands, with many ecosystems depending on groundwater. As a consequence intense groundwater withdrawals for urban use and, above all, irrigation, serious impacts have been observed in eastern part this aquifer, where National Park located. There also exploitation western divide exists. main goal work to analyze impact area. For this, evolution levels since 1968 piezometers and pumping wells has...
Unlike acidic sulfide mine wastes, where metal/loid mobility and bioaccessibility has been widely studied, less attention paid to alkaline cyanide heap leaching wastes. Thus, the main goal of this study is evaluate metal/loids in Fe-rich (up 55%) wastes resulting from historical activities. Wastes are mainly composed oxides/oxyhydroxides (i.e. goethite hematite), oxyhydroxisulfates jarosite), sulfates (i.e., gypsum, evaporitic sulfate salts), carbonates calcite, siderite) quartz, with...
The estuary of Huelva is constituted by the common mouth Odiel and Tinto rivers, which are extreme cases acid mine drainage contamination due to Iberian Pyrite Belt, world's largest sulfide mineral province. drained acidic waters subjected seawater mixing thus, dilution precipitation processes that drive load contaminants entering oceanic environment. This research reports distribution major metal(loid)s present in highly across entire estuarine systems as they neutralization, until reaching...
Uncrewed Aerial Systems (UAS) and satellites are used for monitoring assessing the quality of surface waters. Combining both sensors in a joint tool may scale local water retrieval models to regional global scales by translating UAS-based satellite imagery. The main objective this study is examine whether Sentinel-2 (S2) data can complement UAS data, specifically from MicaSense RedEdge MX-Dual sensor, inland mining environments affected acid mine drainage (AMD). For purpose, comparison...
The Río Tinto, located in the Iberian Pyrite Belt (SW Spain), constitutes an extreme case of pollution by acid mine drainage. Mining area dates back to Copper Age, although large-scale mining massive sulfide deposits did not start until second half 19th century. Due acidic discharges, Tinto usually maintains a pH close 2.5 and high concentrations pollutants along its course. From detailed sampling during hydrological year 2017/18, it was observed that most followed similar seasonal pattern,...
