“…(Ochieng et al 2008). It has been detected that in the contaminated areas, water may contain dissolved metal concentrations as high as 9x10 -7 mol L -1 Cd (Sainz et al 2004) and 2x10 -6 mol L -1 Cr (Bobrowski et al 2004). In the present study, the concentration of Cd and Cr to which the microorganisms were exposed were similar to the values observed in impacted aquatic systems.…”

“…In the south of Europe, Rio Tinto in Spain is one of the greatest ore smelting centers, where over the centuries copper has been produced from polymetallic ores. The main environmental concern in Rio Tinto is contamination of water, sediments, and soils with arsenic rather than with copper (Sáinz et al 2004 ).…”

“…Nevertheless, the peculiarity of this system rests in the character of the fluvial contributions received by both rivers from the drainage basins. The rivers are affected by acid mine drainage (AMD) and transmit to the system all the characteristics of these types of processes, e.g., acid waters (pH<3) with high heavy metal concentrations (Nelson and Lamothe, 1993;Sáinz et al, 2004;España et al, 2005).…”

Impacto del drenaje ácido de mina en las características hidrogeoquímicas del estuario de los ríos Tinto y Odiel (SO España) Abstract pH and chlorinity content of estuarine water and behavior in the concentration of some heavy metals characteristics of acid mine drainage in the suspended matter and dissolved phase have allowed the identification of two mixing process in the Odiel-Tinto rivers estuary: a salt-induced mixing typical of marine estuaries and an acid neutralization process as a result of the mixture of acid fluvial water coming from the drainage basins, which are affected by acid mine drainage (AMD). Thus, the estuary is divided into three zones: (1) zone with acid water and with precipitation of sulphate phases during the beginning of the process of neutralization in the absence of salt-induced mixing, (2) zone with pH values between 4.5 and 7 where a removal of heavy metals in their dissolved phase is produced by coexistence of both mixture processes, and (3) zone where water is slightly basic and the salt-induced mixing produces a redissolution of some elements. Spatial location and extent of these zones within the estuarine system have seasonal variations depending on the volume of fluvial discharge.Keywords: Acid mine drainage, Acid and saline mixing, Tinto-Odiel estuary, hydrogeochemistry ResumenEl contenido de pH y clorinidad de las aguas de estuario y el comportamiento en la concentración de algunos metales pesados característicos del drenaje ácido de mina en la materia suspendida y en la fase disuelta ha permitido la identificación de dos procesos de mezcla en el estuario de los ríos Tinto y Odiel: una mezcla sal inducida típica de estuarios marinos y procesos de neutralización ISSN (print): 1698-6180.
