SOIL-PLANT RELATIONSHIPS AND CONTAMINATION BY TRACE ELEMENTS: A REVIEW OF TWENTY YEARS OF EXPERIMENTATION AND MONITORING AFTER THE AZNALCOLLAR (SW SPAIN) MINE ACCIDENT
Madejon, P., M.T. Dominguez, E. Madejon, F. Cabrera, T. Maranon, and J.M. Murillo.
Science of the Total Environment 625:50-63(2018)
A literature review was conducted to summarize key research findings focused on soil-plant systems at the Aznalcollar mine since the occurrence of a large-scale mine accident in April 1998. The review includes information on mine slurry and contaminated soil characterization and on trace element (TE) monitoring performed over the past 20 years. Lab results on the soil amendments used as a reclamation technique at the site are discussed, focusing on the effects of different types of amendments at different spatial scales and their effectiveness with time. Other lab results discussed include monitoring TEs in soil and their transfer to plants to assess potential toxicity effects in the food web and using plants to biomonitor TEs in the environment. The experience acquired in making the Guadiamar Green Corridor a large-scale soil reclamation and phytoremediation case study is also evaluated
