The presence of microplastics and synthetic microfibers in the environment is increasing, causing an accumulation food chain because their ingestion by different organisms ecological community.This paper deals with importance wastewater treatment plants (WWTPs) as a source from sludge to environment.These micropollutants have been monitored urban WWTP during 2015, after being separated sludge.Micropollutants were extracted flotation, using concentrated solution sodium chloride several...
The presence of primary microplastics in the environment isconsidered a major concern because three main reasons: physical damage to organisms that ingest them, leaching constituent contaminants such as monomers or additives, and sorption inorganic organic chemicals. Microbeads collected from four facial cleansers, personal care product commonly used by European consumers, have been analyzed this paper. variability size distribution, specific surface area, oxidation state polymer whitening...
Abstract Based on research carried out at 67 tailings dams in Spain: (1) contain alternating sedimentary layers with contractive and dilative geomechanical behaviours; (2) saturate quickly but drain more than 10 times slower due to the high-suction capacity of porous sediments (2–300 MPa); (3) over long-term, a stationary flow regime is attained within basin. Four temporal spatial conditions must all be present for tailing failure occur: experience behaviour; fully saturated; effective...
Mine waste constitutes one of the biggest environmental and management problems, both due to its quantity danger when they are rich in toxic elements. There is a wide variety from oxidation ores metal mining areas, sulphide other minerals. These residues may be enriched potentially elements that can spread contaminate ecosystems, farmland villages. This study has focused on characterization evaluation derived metal-bearing abandoned areas. Mineralogy geochemical characteristics were...
The aim of this work is to investigate the causes El Descargador tailings dam failure, at mine district Cartagena–La Unión (SE Spain), in October 1963. Dam stability back analyses have been carried out by applying a geotechnical and geophysical approach. failure occurred form several landslides five different points along structure. rise pore pressure steeped slopes tails, scaling up 40° some sectors, were main causal preparatory factors. Here we propose that static liquefaction most...
The residue of heating to 900 °C in dynamic air atmosphere palladium coordination/organometallic complexes that do not contain P-donor ligands is Pd purity close 95%. This a suitable method for recovering from excess samples produced research laboratories. When P-containing ligands, free or coordinated palladium, are included the blend subjected this oxidant thermal treatment, unexpected inhibition PdO formation takes place. A thorough study decomposition described date supports general...
Salt efflorescences from metal sulphides and their waste are important drivers of pollution both in around mining areas. However, little is known about these supergene minerals, particularly the areas Mediterranean. This study aims to characterise saline leachates a Mediterranean area located Southeast Spain. The physicochemical characteristics were determined using stereomicroscopy compositional analysis, with following techniques: XRD, WDXRF TG-MS. Additionally, assess risk potential...
Abstract Solid state transformations of PdCl 2 , [PdCl (PPh 3 ) ], [Pd(PPh 4 RuCl ⋅H O, [RuCl (p‐cymene)] and ] in three different atmospheres (N air O have been studied by heating to 1000 °C/1400 °C these palladium/ruthenium compounds. The products obtained this way characterized X‐ray diffraction its specific formulation has shown a strong dependence on the precursor complex, atmosphere used temperature. Thus it is possible obtain materials x Pd(1‐ )PdO Ru(1‐ )RuO with variable value...
