Abstract

This study focuses on the physiological response of lettuce grown on Technosols designed for the remediation of soils polluted by potentially harmful elements (PHEs: As, Cd, Cu, Fe, Pb, and Zn). Lettuce plants were grown in five treatments: recovered (RS) and polluted soil (PS) as controls, and three Technosols (TO, TS, and TV) consisting of 60% PS mixed with 2% iron sludge, 20% marble sludge, and 18% organic wastes (TO: composted olive waste, TS: composted sewage sludge, and TV: vermicompost of garden waste). The main soil properties and PHE solubility were measured, together with physiological parameters related to phytotoxicity in lettuce such as growth, photosynthetic capacity, oxidative stress, and antioxidant defence. All Technosols improved unfavourable conditions of PS (i.e., neutralised acidity and enhanced OC content), leading to a significant decrease in Cd, Cu, and Zn mobility. Nevertheless, TV was the most effective as the reduction in PHEs mobility was higher. Furthermore, lettuce grown on TV and TO showed higher growth (+90% and +41%) than PS, while no increase in TS. However, lower oxidative stress and impact on photosynthetic rate occurred in all Technosols compared to PS (+344% TV, +157% TO, and +194% TS). This physiological response of lettuce proves that PHE phytotoxicity is reduced by Technosols. Thus, this ecotechnology constitutes a potential solution for soil remediation, with effectiveness of Technosols depending largely on its components. [ABSTRACT FROM AUTHOR]

10. Recuperación del suelo y la vegetación en una zona afectada por contaminación residual tras la aplicación de medidas de remediación

Abstract

El presente estudio evalua la eficacia de diferentes tratamientos de remediación aplicados en suelos residualmente contaminados afectados por el vertido minero de Aznalcóllar, ocurrido en 1998 (SO de España). Se estudió la influencia de estos tratamientos sobre las principales propiedades del suelo y sobre la evolución de la vegetación. Los resultados mostraron que las enmiendas mejoraron las principales propiedades del suelo y redujeron su toxicidad, lo que condujo a una recuperación natural parcial de la cubierta vegetal y la riqueza de especies en los suelos enmendados. Spergularia rubra y Lamarckia aurea, dos de las principales especies vegetales presentes en la zona y más fuertemente asociadas a altas concentraciones de contaminantes, mostraron un elevado factor de bioacumulación (BAF) para los principales contaminantes en la zona (Pb y As) tanto en parte aérea como en raíz. Lamarckia aurea mostró una elevada acumulación de estos elementos en las raíces, lo que concuerda con su distribución, fuertemente asociada a zonas donde el crecimiento de la vegetación está más limitado. Spergularia rubra y Lamarckia aurea, por tanto, son especies clave en esta zona, ya que pueden favorecer la colonización posterior de estos suelos residualmente contaminados por parte de otras especies menos tolerantes a la contaminación., Revista de Ciências Agrárias, Vol. 45 N.º 4 (2022)

Abstract

Esta investigación ha sido financiada por el Proyecto de Investigación RTI 2018-094327-B-I00 (Ministerio de Ciencia, Innovación y Universidades) y por los Grupos de Investigación RNM-269 y RNM-101 (Junta de Andalucía, España)., El objetivo general de la presente tesis doctoral es evaluar la variación de la disponibilidad y de la toxicidad de metales pesados en suelos contaminados a través del tiempo, para lo cual se eligió el Corredor Verde del río Guadiamar (CVG) como área de estudio. La restauración de suelos debido a la contaminación del vertido de la mina de Aznalcóllar es la más importante que se ha hecho en España y una de las más importantes realizadas en Europa, primero por el grado de contaminación tan alto al que se vieron afectados los suelos y segundo por la gran superficie afectada., The general objective of this Ph.D. Thesis is to evaluate the variation of the availability and toxicity of heavy metals in contaminated soils over time, for which the Guadiamar Green Corridor (GGC) was chosen as the area of study. The soil restoration due to contamination from the Aznalcóllar mine spill is the most important that has been done in Spain and one of the most important carried out in Europe, first of all due to the high degree of contamination to which the soils were affected and second for the large area affected., Tesis Univ.
