La contaminación de los suelos por metales pesados. Una nueva aproximación a la especiación desde el punto de vista cinético

Resumen

Nowadays the public opinion is very sensitive with the problem associated to the heavy metals soil contamination. Environmental catastrophes like the events happened in Aznalcollar and its future effects have shown the serious problem associated to this form of contamination. The study of the different existent species of the metals, as well as its possible biodisponibility, is a section that the diverse authors in a very different way have approached Often, when they are carried out chemical methods of especiación, one does not keep in mind the dependence with the time that you/they have the extraction phenomenon. However, this parameter is probably strongly linked with the mobility or biodisponibility of the metals appearance in the ·soil. The present work applies the kinetic especiación to the heavy metals present in a cultivation soil in which the agronomic sludge application of a wastewater treatment plant has been made. The results of the copper content of these soils in comparison with a reference parcel are presented.
