Data from: Trace element accumulation in woody plants of the Guadiamar Valley, SW Spain: a large-scale phytomanagement case study

Phytomanagement employs vegetation and soil amendments to reduce the environmental risk posed by contaminated sites. We investigated the distribution of trace elements in soils and woody plants from a large phytomanaged site, the Guadiamar Valley (SW Spain), 7 years after a mine spill, which contaminated the area in 1998. At spill-affected sites, topsoils (0-25 cm) had elevated concentrations of As (129 mg kg(-1)), Bi (1.64 mg kg(-1)), Cd (1.44 mg kg(-1)), Cu (115 mg kg(-1)), Pb (210 mg kg(-1)), Sb (13.8 mg kg(-1)), Tl (1.17 mg kg(-1)) and Zn (457 mg kg(-1)). Trace element concentrations in the studied species were, on average, within the normal ranges for higher plants. An exception was white poplar (Populus alba), which accumulated Cd and Zn in leaves up to 3 and 410 mg kg(-1) respectively. We discuss the results with regard to the phytomanagement of trace element contaminated sites.Trace elements in soils and plants from Guadiamar River Valley (SW Spain)This data set contains information on chemical composition of soils and woody plant biomass from the Guadiamar River Valley (SW Spain). The data set corresponds to a series of environmental surveys conducted in the Guadiamar River Valley (SW Spain), to monitor de fate of contaminating trace-elements in soils and aboveground plant biomass (main tree species), after a huge mine accident that released acid waters and trace-element contaminated sludge into the Guadiamar River basin. Data included in this set were gathered in Autumn 2005, six years after the mining accident (occurred in April 1998) and subsequent remediation programme.GUADIAMAR_TE2005.cs
