The Tinto river drains the Rio mining district, which comprises world’s largest known massive sulfide deposits; these orebodies have been mined from third millenium BC to present. is strongly acidic (pH, 1.5–2.5); during flood events, it transports a sandy material, including abundant detrital pyrite grains. A core drilled in Holocene sediments of estuary allows for investigation recent and historical pollution. Two anomalous horizons recognized (0–1.3 m; 3–4 m). Both are characterized by...
pH and chlorinity content of estuarine water behavior in the concentration some heavy metals characteristics acid mine drainage suspended matter dissolved phase have allowed identification two mixing process Odiel-Tinto rivers estuary: a salt-induced typical marine estuaries an neutralization as result mixture fluvial coming from basins, which are affected by (AMD). Thus, estuary is divided into three zones: (1) zone with precipitation sulphate phases during beginning absence mixing, (2)...
The concentration of rare earth elements together with Sc, Y, and U, as well fractionation patterns, in the water an affected acid mine drainage system were investigated. Significant dissolved concentrations studied observed fluvial sector this estuary (Sc ∼ 31 μg L−1, Y 187 U 41 Σ ∼621 L−1), pH values below 2.7. In mixing zone estuary, are lower 2.1 L−1; 16.7 4.8 ∼65.3 L−1) show a strong longitudinal gradient. largest removal occurs medium-chlorinity it becomes extreme for heavy elements,...
