Depuration of eutrophic water in wetlands affected by mining wastes in the Mar Menor lagoon: consequences of the channalization of watercourses and effects of calcium carbonate and hydromorphic conditions on biogeochemical processes
The specific objectives were:
1. Establish if the capacity of the coastal wetlands of the Mar Menor to reduce the contents of nitrogen and phosphorus in the waters that flow along them decreases due to the construction of ponds and channels.
2.- To establish if liming in wetlands affected by mining wastes can be a suitable management option to improve chemical and physical soil properties and if these improvements could contribute to the growth of plants.
Use of native plant species to restore/stabilize mine tailings of the Sierra of Cartagena-La Unión (15296/PI/10)
Mine tailings are one of the main environmental problems associated to mine activity. The phytomanagement of abandoned mine tailings has been proposed as a suitable tool to effect their surface stabilisation and thus, decreases their environmental risks. The project consisted of determining the edaphic and ecophysiological factors which conditions the phytomanagement of mine tailings under semiarid climate.
Relations between biogeochemical cycles and the role of wetlands as green filters: effects of eutrophication, plant species and the season of the year for carbon sequestration.
Specific objectives are:
1. Determine to what extent the decomposition of the "litter" from different plant species is influenced by the presence of high nitrogen, phosphorus and dissolved organic carbon contents in eutrophicated waters and if this is related to the season of the year in which flooding-drying phases ocurr
Ecophysiological and ecotoxicological evaluation of the combined used of biochar and native tree species autóctonas for restoring mining wastes in the Cartagena-La Unión Mining District (19248/PI/14)
The project will provide scientific and technical solutions fo rrestoring mining wastes in the Sierra of Cartagena-La Unión. This semiarid area is epsecially sensistive to climate change. The project will include the evaluation of the ecotoxicological risks associated to metal(loid)s. The main goal of the project was to evaluate the effect of the biochar and/or organic municipal waste on the behaviour of native tree species.
The project contains a experimental part in the lab and in situ samplings.
Field part
Functionality and resilience of soils polluted by mining wastes under climate change conditons in mediterranean environments: ecotoxicological aspects and the use biochar for remediation ( CGL2016-80981-R-2)
The Intergovernmental Panel on Climate Change (IPCC) predicts increasing levels of atmospheric CO2 and air temperatures as well as decreasing soil moisture, the soils being among the most affected components of terrestrial ecosystems, especially in the Mediterranean area. Due to the importance of soil functions (organic matter/nutrient cycling, productivity, etc.), its response against such changes is crucial for assessing how terrestrial ecosystems might adapt and/or contribute to mitigate global warming.
Evaluation of the toxicity of mining wastes using bioassays with plants and soil invertebrates: remediation with biochar from municipal waste refuse and sludge of waste water treatment plants (CGL2013-49009-C3-1-R)
The risks of toxicity by metals/metalloids due to mining wastes pollution take place in the mine tailings, but also in lowland areas such as wetlands due to the erosion of the tailings and the transportation of wastes to these topographically depressed positions. In this Project, we work in field and experimental conditions, performing toxicity tests with seeds, seedings, young/adult plants and soil invertebrates.
