ABSTRACT

Tras muestrear individuos de liebre en diversas zonas el Corredor Verde del Guadiamar, se procede a procesar muestras de tejidos de hígado y músculo para analizar sus contenidos en As, Cd, Pb, Cu y Zn, elementos químicos de especial significado ambiental, sobre todo en una zona de tradición minera, que además fue afectada por una catástrofe ambiental de gran magnitud por la rotura de una balsa de estériles (donde se acumulaban los restos del procesado del mineral) con altas concentraciones de metales pesados en forma de lodos y aguas contaminadas, en abril del año 1998. Los resultados muestran una situación de mejora ambiental y de normalidad si se comparan con los valores encontrados en bibliografía especializada y los animales empleados como control


After having collected samples of brown hares in several areas from the Guadiamar Green Corridor, the following step consisted of processing samples of both liver tissues and muscle so as to analyse their As, Cd, Pb, Cu and Zn constituents. These are chemical elements with a special environmental significance, especially in an area with mining tradition which was, in addition, affected by an important environmental disaster that took place in April 1998 as a result of the collapse of the retention wall of the talings dam, containing a high proportion of heavy metals in the form of sludge and contaminated water.The results indicate a situation of normality and even environmental improvement when compared with the results appearing in specialized reference literature and in the individuals used as control
