Martínez Sánchez, María José ; Navarro, M. C. ; Pérez Sirvent, Carmen ; Marimón, J. ; Vidal, JU. ; García Lorenzo, Mari Luz ; Bech, Jaume | Elsevier | 2008A study on metal mobilisation (Zn, Pb and As) from contaminated sediments in Portman Bay (SE Spain) was carried out. Thisarea has suffered a major impact from mining activity, as millions of tons of mine tailings have been dumped into the bay ov[...]texto impreso
García Lorenzo, Mari Luz ; Herrero, María José ; Martínez Sánchez, María José ; Molina Ruiz, José ; Hernández Nicolás, Carmen María ; Bech, Jaume ; Pérez Sirvent, Carmen | EGU General Assembly | 2017In freshly deposited sulphidic mine tailings, the pH is neutral or slightly alkaline. Due to pyrite oxidation, the pH decreases to values lower than 3 at which acidophilic iron- and sulphur-oxidizing prokaryotes prevail and accelerate the oxidat[...]texto impreso
Pérez Sirvent, Carmen ; Hernández Pérez, Carmen ; Martínez Sánchez, María José ; García Lorenzo, Mari Luz ; Bech, Jaume | Springer | 2016-04Purpose Mining activities generate large amounts of wastes that may contain potentially toxic elements (PTE), which, if released into the environment, may cause air, water and soil pollution long after mining operations have ceased. This paper d[...]texto impreso
Pérez-Sirvent, Carmen ; Martínez Sánchez, María José ; Veiga, José Manuel ; Bech, Jaume ; García Lorenzo, Mari Luz | Elsevier | 2019-12Mining-contaminated surface waters and acid mine drainage frequently contain high levels of potentially harmful metal(oid)s, some of which are especially relevant because of their toxicity- As, Pb, Cd and, to a lesser extent, Cu and Zn. Limeston[...]texto impreso
Pérez Sirvent, Carmen ; Hernández Pérez, Carmen ; Martínez Sánchez, María José ; García Lorenzo, Mari Luz ; Bech, Jaume | Springer | 2017Purpose This study was undertaken to determine the feasibility of using three aquatic macrophytes, Phragmites australis, Juncus effusus and Iris pseudacorus, to phytoextract potentially toxic elements (PTEs) from a contaminated area by mining ac[...]texto impreso
García Lorenzo, Mari Luz ; Pérez-Sirvent, Carmen ; Martínez Sánchez, María José ; Molina Ruiz, José ; Martínez, Salvadora ; Arroyo, Xabier ; Martínez Martínez, Lucía Belén ; Bech, Jaume | Geological Society | 2018A total of 120 sediments from 12 cores of Portman Bay (SE Spain) were studied to assess the degree of contamination and ecological risk related to potentially toxic elements (PTEs) by combining a geochemical and mineralogical characterization wi[...]texto impreso
Martínez Sánchez, María José ; García Lorenzo, Mari Luz ; Pérez Sirvent, Carmen ; Bech, Jaume | Elsevier | 2012Trace element contamination has been a serious problem in the vicinity of abandoned mine sites. In the studied area, mining activities have produced great amounts of wastes, characterized by high trace elements content, acidic pH and minerals fr[...]
