The mobility, bioavailability and toxicity of mercury in the environment strongly depend on chemical species which it is present soil, sediments, water or air. In mining districts, differences mobility mainly arise from different type mineralization ore processing. this work, synchrotron-based X-ray absorption near-edge spectroscopy (XANES) has been taken advantage to study speciation geological samples three largest European districts: Almadén (Spain), Idria (Slovenia) Asturias (Spain)....
The derelict Remance gold mine is a possible source of pollution with potentially toxic elements (PTEs). In the study area, diverse waste has been left behind and exposed to weather conditions, poses risks for soil, plants water bodies, also health local inhabitants. This sought perform an ecological risk assessment mining areas incomplete remediation, including: (i) characterizing geochemical distribution PTEs; (ii) assessing by estimating load index (PLI) potential (RI); (iii) soil...
The geochemical characterization of the mine deposits and soils in metal mining areas is essential order to develop an effective reclamation strategy. determination total potentially toxic element (PTE) content, together with application chemical extraction procedures, can give insight into behavior contaminants after different solutions, as well identify where urgent action needed. This work presents a practical evaluation pollution potential trace elements affected by activities, be used...
Mining affects the environment, particularly through persistence of accumulation tailings materials; this is aggravated under tropical climatic conditions, which favours release potentially toxic elements (PTEs) bioavailable to local flora and fauna supposing a risk human health. The Remance gold mine (Panamá), exploited intermittently for more than 100 years, has remained derelict over 20 years. Within area live farmers who carry out subsistence agriculture livestock activities. objective...
This work aims to establish Sb mobility, its transfer biota and effect on soil health in a semi-arid climate. The results show the presence of stibnite (Sb2S3) as main primary compound, bindhemite (Pb2Sb2O6(O,OH)), minor proportions stibiconite (Sb3+(Sb5+)2O6(OH)) oxidised species. research also observes very high total contents mining materials (max: 20,000 mg kg-1) soils (400-3000 kg-1), with physical dispersion around restricted 450 m. soil-to-plant is low, (bioaccumulation factor:...
Usagre (Badajoz, SW Spain) mercury mine was active for an undetermined time until its closure in 1971. The ore exploited this cinnabar (red HgS), and metallurgy also performed locally by means of primitive furnaces the Bustamante type. Since mine, reclamation measures have not been carried out at site, actual passives include a shaft, accessible descending gallery dump adjacent to gallery. In work described here, data from two soil geochemistry surveys were combined analysed. separated...
<p>Antimony (Sb) is a valuable element, exploited for diverse applications including flame retardants, munitions, batteries, glasses, and industry diodes. However Sb also toxic metalloid, often associated with other harmful elements (arsenic, lead, mercury…) in mining sites. The biogeochemical behavior of remains poorly documented, data must be acquired order to elaborate solid environmental studies related mining. Here, the mobility from phases present former...
