Reconocimiento de suelos y estudio de su contaminación por metales pesados en el Valle del Guadiamar

Abstract

[ES]: Se estudian suelos del valle del Guadiamar distribuidos entre la superficie aluvial (afectada por el vertido minero) y los primeros niveles de terrazas. Los suelos se representan en una cartografía a escala 1/20.000 y se muestrean los diferentes perfiles representativos de la diversidad edáfica existente. A partir de dichos perfiles se hace un estudio comparativo entre la contaminación que haya podido aportar tradicionalmente el Guadiamar en los suelos más antiguos (terrazas) y la producida más recientemenle en los suelos aluviales y, sobre todo, después del accidente ocurrido por la rotura de la balsa que contenían los residuos de la explotación minera de Aznalcóllar.

EN]: Soils of two areas in the Guadiamar ri ver valley- affected and unaffected by the Aznalcóllar mine tailing spill, happening in April 1998 -are studied. Soils were mapped at 1:20000 scale, and representative profiles of all soil map units were sampled. Levels of heavy metals are compared in the oldest soils of upper areas (considered as background levels) and in the younger soils located in the Guadiamar alluvial plain (affected by centuries of mining activity, and strongly affected by the toxic flood).
