Elementos traza y nutrientes en plantas y suelos afectados por el vertido minero de Aznalcóllar

Abstract

El complejo minero de Aznalcóllar está situado en el extremo suroriental del cinturón pirítico ibérico, que constituye la más vasta e importante provincia vulcanogénica de sulfuros masivos (depósitos polimetálicos) del oeste de Europa, e incluye a Río Tinto, Aljustrel, Neves Corvo, Tharsis, Sotiel y Aznalcóllar. Se extiende a través de 200 km (unos 8000 km2 de superficie) desde el suroeste de Portugal hasta Sevilla (Alastuey et al., 1999; López-Pamo et al., 1999). La madrugada del 25 de abril de 1998, el dique de contención de la balsa de decantación de la mina de los Frailes en Aznalcóllar (Sevilla), situada en la margen derecha del río Agrio, a 2 km de su confluencia con el Guadiamar, se desplazó unos 60 m, dejando abierta una brecha de unos 50 m. Por ella salió una mezcla de lodos y aguas ácidas que inundaron las cuencas de los ríos Agrio y Guadiamar, a lo largo de 60 km, comprendidas entre la balsa y la zona denominada Entremuros, en el límite del Parque Nacional de Doñana. La construcción de muros de contención antes de que llegara la riada, en la zona de Entremuros, impidió que la contaminación se extendiese al Parque y llegara directamente al río Guadalquivir, contaminando su rico estuario (Cabrera, 2000).

El presente trabajo se ha realizado en el marco del CONVENIO ESPECÍFICO CONSEJERÍA DE MEDIO AMBIENTE (JUNTA DE ANDALUCÍA – CSIC) PARA EL SEGUIMIENTO DE SERES VIVOS EN EL ÁREA AFECTADA POR EL VERTIDO DE LAS MINAS DE BOLIDEN - APIRSA, S. L., dentro del PROGRAMA DE INVESTIGACIÓN DEL CORREDOR VERDE DEL GUADIAMAR (PICOVER) (Línea de Investigación 1: Seguimiento, Vigilancia, Control y Remediación de la Contaminación Generada por el Vertido Minero).

La presente Memoria de Investigación presentada para optar al grado de Doctor en Biología, ha sido realizada en el Departamento de Sostenibilidad del Sistema Suelo-Planta-Atmósfera.
