Informing people about the toxicity risks by soil contamination

Pollution is the largest environmental cause of disease and premature death in the world today however it has been neglected, according to the Lancet Commission on pollution and health. In particular, polluted soils threaten the environment and human health. The persistent substances such as metals are contaminants posing the greatest threats to health.

Soil contamination and colonization by ectomycorrhizal fungi associated with holm oak

The environmental disaster caused by the breakdown of the decanting basin of the Aznalcóllar mine, Seville (in 1998), left behind hectares of contaminated land. The tasks of decontamination and restoration of the ecosystem led to the establishment of a green and environmentally protected area, the Guadiamar Green Corridor. The restoration was carried out […]

Measures to remediate contaminated soils: the Guadiamar case study

Soil pollution is one of the main environmental problems at a global scale. Within the European RECARE project, several threats of soil degradation are investigated, and measures and solutions to remediate degraded soils are proposed.

A research team from the IRNAS, CSIC participating in the RECARE project has contributed with the […]

Twenty years of environmental studies in the Guadiamar

The Aznalcóllar mine accident (April 1998) was a large-scale ecological and socio-economic catastrophe in the South of Spain. Since then, the Research Group SOIL-PLANT in the IRNAS, CSIC has been working on the area affected by the mine spill, currently known as Guadiamar Green Corridor.

RECARE workshop on ecosystem services

Ecosystem services are the direct and indirect contributions of ecosystems to the human wellbeing. The remediation of contaminated soils after the Aznalcóllar mine spill, and the restoration of the Guadiamar Green Corridor (Sevilla, Spain) provide with multiple ecosystem services to local and regional societies.

Potential of eucalypt trees for remediation of contaminated soils

The use of trees to immobilize contaminants (phytostabilization) is a low-cost and effective method of soil remediation.

Researchers of IRNAS, CSIC and New Zealand have evaluated the potential of red gum (Eucalyptus camaldulensis) to phytostabilize soils contaminated by trace elements (TE). Within the research projects RECARE and RESTECO, the ET concentration in soils and in […]

European meeting about prevention and remediation of degraded soils

Researchers of the Group SOIL-PLANT, from the IRNAS, CSIC, participated in the RECARE project Plenary Meeting, devoted to prevention and remediation of degraded soils, which has been held at Hella (Iceland), from May 29th to June 2nd 2017.

The role of soil in the facilitation effect by the retama shrub

Shrubs are considered to be hotspots of soil fertility and biological activity in dry ecosystems. The use of shrubs, like “retama” (Retama sphaerocarpa (L.) Boiss.), as nurse plants to facilitate woody plant recruitment has been proved to be particularly useful for the revegetation of highly disturbed environments, such as contaminated lands.

New framework for soil-related ecosystem services

Ecosystem services are the direct and indirect contributions of the ecosystems to the human well-being.

Changes in the natural capital’s properties influence soil processes, which support the provision of ecosystem services. The benefits produced by these ecosystem services are explicitly or implicitly valued by individuals and society. This can influence decision- […]

Participative evaluation of the best measures for remediating contaminated soils: Guadiamar Green Corridor

The Guadiamar Green Corridor (in Sevilla province, Spain) is one of the 17 case studies within the European project RECARE (2014-2018), which main aim is to find ways of assessing the current threats to soils and finding innovative solutions to prevent further soil degradation across Europe.

On February 17th 2016 we had a Participative Workshop […]
