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.

Characterization and monitoring of the flora, vegetation and soils of the Agua Amarga salt marsh (Alicante, Spain)

Groundwater withdrawal by desalination plants might lead to a drop of the piezometric levels of aquifers,causing negative impacts, especially in water-dependent ecosystems. Management strategies are necessary to overcome these potential problems, particularly in abandoned solar saltworks, wetlands which are particularly prone to degradation by desiccation. This proyect aims to asses a pioneer programme of irrigation with seawater to correct the environmental impacts of two desalination plants in Agua Amarga salt marsh, SE Spain.

Evaluation of risks due to mine wastes in salt marshes of the coastal area of the Mar Menor (SE Spain): processes of metal mobilization in soils and bioaccumulation in plants and molluscs.

A detailed study of soil-plants-hydromorphy interactions is proposed which includes ecotoxicologycal aspects jointly with the identification of biomarkers of pollution in areas with high biodiversity. The research will be developed in two salt-marshes located in the coastal area of the Mar Menor (SE Spain). These sites are characterised by soils polluted by metal mine wastes, they have a high biodiversity and they suffer an intense human pressure.
