Influencia del material geológico y detección de anomalías en el contenido de metales pesados en horizontes superficiales de suelos de la Provincia de A Coruña

Abstract

[Resumen] Los contenidos totales de Cr, Ni, Cu, Zn, Pb, Co y Mn en horizontes superficiales de suelos desarrollados sobre diferentes materiales geológicos de la provincia de La Coruña, ponen de manifiesto la importancia del factor litológico respecto a los aportes de origen antrópico. Los suelos sobre rocas ultramáficas y máficas muestran contenidos de Cr, Ni YCu que superan en muchas ocasiones los umbrales considerados de fitotoxicidad por diferentes autores. Le siguen los esquistos ricos en biotita, mientras que sobre granitos y pizarras se obtienen los valores medios más bajos. Los resultados obtenidos permiten realizar una primera aproximación acerca de la «aptitud» de los suelos de cultivo como receptores de lodos residuales..

[Abstract] The total contents of Cr, Ni, Cu, Zn, Pb, Co and Mn in superficial horizons of soils that are developed on different geological materials of La Coruña region (Spain), reveal the importance of the lithologic factor with respect to the contribution of anthropic. origino The soils on ultramafic and mafic rocks show contents of Cr, Ni and Cu that are many times higher than threshold considered phytotoxic by different authors. These are followed by the schists, rich in biotite, while the lowest average values are obtained on granites and slates. The obtained results allow a first approach about the «attitude» of the cultivable soils as receptore of waste sludge.
