Phytoremediation of the polluted soils after the toxic spill of the Aznalcollar mine by using wild species collected in situ
The accident of the Aznalcollar mine on April 1998 in the proximity of the Donana National Park (southern Spain) led to the contamination of the Guadiamar river and the adjacent agricultural areas (5000 Ha). After physically removing the sediments the soils have remained polluted by heavy metals such as Pb, Cu, Zn, Cd, Tl, Sb and metalloids as As. Periodical field surveys have been made in the affected land in order to identify the metal tolerant species that are spontaneously growing in the polluted soils. From the ninety six different plant species collected, Amaranthux blitoides (accumulation of As, Pb and Cu), Erodium moschatum (accumulation of Zn) and Lavatera cretica (accumulation of Cd) highlight as the most promising species to be used with phytoremediation purposes.
