TL;DR: This study presents an estimation of the seasonal variation, and the dissolved contaminant load transported by both rivers from February 2002 to September 2004, showing a higher percentage of fractionation and bioaccumulation of these metals in the station influenced by the fresh water environment.
Journal ArticleDOI
Seasonal water quality variations in a river affected by acid mine drainage: the Odiel River (South West Spain)
TL;DR: Seasonal variations of the quality of the water of the Odiel River is analyzed, a region containing an abundance of massive sulphide deposits and the most abundant metals in the water are zinc (Zn), iron (Fe), manganese (Mn) and copper (Cu).
Journal ArticleDOI
Hydrogeochemical characteristics of the Tinto and Odiel Rivers (SW Spain). Factors controlling metal contents.
TL;DR: The Tinto and Odiel Rivers are strongly affected by acid mine drainage (AMD) due to the intense sulphide mining developed in their basins over the past 5000 years, and the results obtained from a weekly sampling in both rivers are analysed.
Journal ArticleDOI
Evaluation of the dissolved contaminant load transported by the Tinto and Odiel rivers (South West Spain)
TL;DR: The Tinto and Odiel rivers are heavily affected by acid mine drainage (AMD), and the exact quantities of contaminants transported into the Huelva estuary and the Gulf of Cadiz are unknown.
Journal ArticleDOI
Hydrochemical characteristics and seasonal influence on the pollution by acid mine drainage in the Odiel river Basin (SW Spain)
TL;DR: The Odiel river basin is heavily affected by acid mine drainage from the sulphide mining areas in the Iberian Pyrite Belt (IPB), and a thorough study has been conducted along this fluvial system, monitoring the seasonal influence on the pollution level and its hydrochemical characteristics as discussed by the authors.
