EVALUATION OF METAL AND METALLOID CONTENTS OF THE SOILS IN THE WADIS OF THE SIERRA MINERA DE CARTAGENA-LA UNIÓN, SLOPES TO THE MAR MENOR. T.T.M.M. OF CARTAGENA AND LA UNIÓN (MURCIA)
The work is structured in two tasks:
Task 1. Report including the interpretation and evaluation of the soil sampling and analysis campaign. A report must be drawn up interpreting the results obtained in the sampling and analytical campaign carried out by the Directorate General for Biodiversity, Forests and Desertification in order to then proceed to the evaluation of the soils present in the wadis from the point of view of their danger or risk to human health and the environment.
REPORT ON THE TREATMENT FOR DENITRIFICATION OF WATER FROM THE QUATERNARY AQUIFER OF CAMPO DE CARTAGENA USING A BIOREACTORS SYSTEM
PHASE 1. Initial proposal on the possible treatment lines (similar to a study of alternatives) including information on their feasibility and recommendations for the design of the lines (first conceptual or strategic advance).
SERVICE FOR THE ENVIRONMENTAL MONITORING AND SURVEILLANCE OF THE AGUA AMARGA SALT MARSH AND ITS SURROUNDINGS (AC/ALICANTE). CÓD.EXP. V-10/21-02
Application of phytomanagement techniques for environmental restoration of metalliferous mining waste deposits from semi-arid areas (FiAmbRes) PDC2021-121263-I00.
Mine tailings piles (left over from mining refining operations) store waste from ore processing and are considered the main responsible for the environmental problems in former metal mining areas. Due to the large number of abandoned piles, public authorities must prioritize actions in those that pose an unacceptable risk and where urgent action is necessary due to the collapsing risk and/or proximity to cities. These types of actions are much expensive, since they involve a high technical-engineering
Functional aspects and soil ecotoxicity of abandoned mine wastes colonized by vegetation vs restored in semiarid areas: response to climate change (WARMET) PID2020-118941RA-I00
Soil pollution is one of the major threats facing terrestrial ecosystems. Metal mine wastes from ore processing are among the most hazardous residues (high metal levels, extreme pH, high salinity, organic matter/nutrients deficiency, poor physical structure). These wastes are often deposited in open-air piles (mine tailings). Classic-restoration approaches (technical reclamation) usually involve topsoil capping aiming to create a new soil above wastes and then afforestation. These options have been questioned in (semi)arid regions due to ecosystem inability to be self-sustaining.
METAL CONTAMINATION IN A GLOBAL WARMING PERSPECTIVE Effects on soil properties and relation with toxicity changes
Global climate change might intensify the hazardous effects of anthropogenic metal contamination in terms of soil toxicity risks and thus effects of loss of soil functionality and sustainability. The scientific research performed in this field has been mostly focused on the effects of single climate factors, while less attention has been paid to the combination of multiple climate factors.
Sustainability for the phytomanagement of mining polluted soil: an ecophysiological and microbiological approach (CGL2017-82264-R)
The proposal includes field and experimental phases. The latter will be performed in mesocosms. The field part has as a main goal to evaluate the influence of edpahic gradients in the structure of the microbial populations in semiarid mine tailings. In addition, the effects of seasonal dynamics on ecology/ecophysiology of selected endemic plant species will be performed.
Evolution of soil and vegetation in semiarid Mediterranean salt marshes in relation to human activities: the role of soils in nutrient, metal and pesticide retention.
The project focus on the evolution of soil and vegetation in two mediterranean salt marshes of SE of Spain. In previous studies (1991-1993) we identified plant zonation and edaphic gradients in these salt marhes. Now, the objectives are as follow: 1.- to identify the evolution of soils (salinity, water regime and nutrients) and vegetation (cover and species diversity) in the last 10 years, and to relate these changes with human activities (agriculture practices and others) in nearby areas.
