Assessing the ecotoxicological effects of long-term contaminated mine soils on plants and earthworms. Relevance of soil (total and available) and body concentrations

The final publication is available at Springer via http://dx.doi.org/10.1007/s10646-014-1262-2The interactions and relevance of the soil (total and available) concentrations, accumulation, and acute toxicity of several essential and non-essential trace elements were investigated to determine their importance in environmental soil assessment. Three plant species (T. aestivum, R. sativum, and V. sativa) and E. fetida were simultaneously exposed for 21 days to long-term contaminated soils collected from the surroundings of an abandoned pyrite mine. The soils presented different levels of As and metals, mainly Zn and Cu, and were tested at different soil concentrations [12.5, 25, 50, and 100 % of contaminated soil/soil (w/w)] to increase the range of total and available soil concentrations necessary for the study. The total concentrations in the soils (of both As and metals) were better predictors of earthworm uptake than were the available concentrations. In plants, the accumulation of metals was related to the available concentrations of Zn and Cu, which could indicate that plants and earthworms.accumulate elements from different pools of soil contaminants. Moreover, Zn and Cu, which are essential elements, showed controlled uptake at low concentrations. The external metal concentrations predicted earthworm mortality, whereas in plants, the effects on growth were correlated to the As and metal contents in the plants. In general, the bioaccumulation factors were lower at higher exposure levels, which implies the existence of auto-regulation in the uptake of both essential and non-essential elements by plants and earthwormsThis work was financed by the Community of Madrid through the EIADES Project (S-2009/AMB/1478) ) and by the Spanish Ministry of Education and Science project CTM2010-21922-C02-0

Recursos periodísticos en la construcción del relato sobre las consecuencias de la crisis económica en la población

The current research studies the use of some tools, in the discourse elaborated by the press, to report the effect of the first crisis of the 21st century in the Spanish population. This aim has been developed from the corpus created with the informative pieces published in the most influential newspapers in a Spanish city (Vigo), of strategic importance for the economy of its surroundings, whose model could be extrapolated to other cities with similar characteristics. The period under study (from September 2009 to July 2011) was determined by considering two events that had a significant effect on the economic crisis affecting the considered region. Within this period, the sample was created from the informative pieces published on the 23 weeks selected for the current research, which fulfilled the criteria established for the search.  With the resulting data, an exploratory analysis has been carried out to determine the use of the following resources: presence on the front page, journalistic genre and accompaniment of photographs or other graphic elements. The results of this study have also been used to inquire about the effects of the crisis itself on the media and their influence on the message transmitted.La presente investigación estudia el uso de algunas herramientas, en el discurso elaborado por la prensa, para narrar el efecto de la primera crisis del siglo XXI en la población española. Este objetivo se ha desarrollado a partir del corpus creado con las piezas informativas publicadas en los periódicos de mayor influencia en una ciudad española (Vigo), de importancia estratégica para la economía de su entorno, cuyo modelo sería extrapolable a otras urbes de similares características. Para delimitar el período de estudio (de septiembre de 2009 a julio de 2011), se tomaron como referencia dos hechos que tuvieron especial relevancia en la crisis económica que vivió la región considerada. Dentro de este marco temporal, se construyó la muestra a partir de las piezas informativas publicadas en las 23 semanas seleccionadas para esta investigación, que respondían a los criterios establecidos para la búsqueda.  Con los datos resultantes, se realizó un análisis exploratorio para determinar la utilización de los siguientes recursos: presencia en portada, género periodístico y acompañamiento de fotografías u otros elementos gráficos

Synthesis of borasiloxanes by oxidative hydrolysis of silanes and pinacolborane using Cu3(BTC)2 as a solid catalyst

[EN] A convenient method for the synthesis of borasiloxanes from silanes and pinacolboranes using Cu-3(BTC)(2) as a heterogeneous catalyst in acetonitrile at 70 degrees C is reported. This procedure is more convenient than Ru and Pd based homogeneous catalysts because it avoids the use of noble metals, easy handling of starting materials and the catalyst can be reused.AD thanks the University Grants Commission (UGC), New Delhi, for the award of an Assistant Professorship under its Faculty Recharge Programme.

The selective reduction of NOx with propene on Pt-beta catalyst: a transient study

The mechanism of the NO/C3H6/O2 reaction has been studied on a Pt-beta catalyst using transient analysis techniques. This work has been designed to provide answers to the volcano-type activity behaviour of the catalytic system, for that reason, steady state transient switch (C3H6/NO/O2 → C3H6/Ar/O2, C3H6/Ar/O2 → C3H6/NO/O2, C3H6/NO/O2 → Ar/NO/O2, Ar/NO/O2 → C3H6/NO/O2, C3H6/NO/O2 → C3H6/NO/Ar and C3H6/NO/Ar → C3H6/NO/O2) and thermal programmed desorption (TPD) experiments were conducted below and above the temperature of the maximum activity (Tmax). Below Tmax, at 200 °C, a high proportion of adsorbed hydrocarbon exists on the catalyst surface. There exists a direct competition between NO and O2 for Pt free sites which is very much in favour of NO, and therefore, NO reduction selectively takes place over hydrocarbon combustion. NO and C3H6 are involved in the generation of partially oxidised hydrocarbon species. O2 is essential for the oxidation of these intermediates closing the catalytic cycle. NO2 is not observed in the gas phase. Above Tmax, at 230 °C, C3H6 ads coverage is negligible and the surface is mainly covered by Oads produced by the dissociative adsorption of O2. NO2 is observed in gas phase and carbon deposits are formed at the catalyst surface. From these results, the state of Pt-beta catalyst at Tmax is inferred. The reaction proceeds through the formation of partially oxidised active intermediates (CxHyOzNw) from C3H6 ads and NOads. The combustion of the intermediates with O2(g) frees the Pt active sites so the reaction can continue. Temperature has a positive effect on the surface reaction producing active intermediates. On the contrary, formation of NOads and C3H6 ads are not favoured by an increase in temperature. Temperature has also a positive effect on the dissociation of O2 to form Oads, consequently, the formation of NO2 is favoured by temperature through the oxygen dissociation. NO2 is very reactive and produces the propene combustion without NO reduction. These facts will determine the maximum concentration of active intermediates and consequently the maximum of activity.The authors thank the Spanish Ministry of Education and Science (project CTQ2005-01358) for the financial support

Risk assessment of an abandoned pyrite mine in Spain based on direct toxicity assays

This is the author’s version of a work that was accepted for publication in Science of the Total Environment. Changes resulting from the publishing process, such as peer review, editing, corrections, structural formatting, and other quality control mechanisms may not be reflected in this document. Changes may have been made to this work since it was submitted for publication. A definitive version was subsequently published in [SCIENCE OF THE TOTAL ENVIRONMENT 470-471 (2014)] http://dx.doi.org/10.1016/j.scitotenv.2013.09.101This research reports the risk assessment of an abandoned pyrite mine using direct toxicity assays of soil and groundwater samples taken at the site. The toxicity of As and heavy metals from mining soils to soil and aquatic organisms was studied using the Multispecies Soil System (MS-3) in soil columns. Ecotoxicological assessment was performed with soil samples diluted with a control soil at concentrations of 12.5, 25, 50 and 100% test soil/ soil (w/w). In this way, changes in the mobility and bioavailability of soil contaminants due to changes in geochemical soil properties via soil dilution were studied. The toxicity of water samples was tested on algae and Daphnia magna. The assessment of the mining area indicated that the current presence of As and heavy metals at the site may cause injuries to soil and aquatic organisms in the entire research area. Moreover, this investigation demonstrated that changes in geochemical conditions can increase the availability of arsenic and, consequently, the environmental risk of these soils. A good correlation was not found between toxicity parameters and the concentrations of soil contaminants based on total and extracted element concentrations. This finding reinforces the usefulness of direct toxicity assays for evaluating environmental riskThis work has been financed by the Community of Madrid through EIADES Project S-2009/AMB/1478 and by the Spanish Ministry of Education and Science, project CTM-2007-66401-CO2/ TECNO and CTM2010-21922-C02-0

Permission from IEEE must be obtained for all other users, including reprinting/ republishing this material for advertising or promotional purposes, creating new collective works for resale or redistribution to servers or lists, or reuse of any copyrighted components of this work in other works."With the spectrum liberation obtained by the deployment of digital terrestrial television and the analog TV switch-off, new bands are being assigned to IMT LTE. In the first cellular deployments in the digital dividend at the 800 MHz band, problems emerged due to the interference cellular networks can cause to DTT signals. Possible solutions imply either an inefficient use of the spectrum (increasing the guard band and reducing the number of DTT channels) or a high cost (using anti-LTE filters for DTT receivers). The new spectrum allocated to mobile communications is the 700 MHz band, also known as the second digital dividend. In this new IMT band, the LTE uplink is placed in the lower part of the band. Hence, the ITU-R invited several studies to be performed and reported the results to WRC-15. In this article, we analyze the coexistence problem in the 700 MHz band and evaluate the interference of LTE signals to DTT services. Several coexistence scenarios have been considered, and laboratory tests have been performed to measure interference protection ratios.Fuentes, M.; García Pardo, C.; Garro Crevillen, E.; Gómez Barquero, D.; Cardona Marcet, N.

MIL-101 promotes the efficient aerobic oxidative desulfurization of dibenzothiophenes

[EN] MIL-101 promotes aerobic oxidation in n-dodecane of dibenzothiophene (DBT) and its methyl-substituted derivatives to their corresponding sulfones with complete selectivity, without observation of the sulfoxide. DBT sulfones can be completely separated from n-dodecane by water extraction. MIL-101(Cr) without the need of pre-activation was found to be more convenient than the also-active MIL-101(Fe) analog. The reaction exhibits an induction period due to the diffusion inside the pore system of the solvent or oxygen and it is not observed if the MIL-101 sample is first in contact with the solvent at the reaction temperature for a sufficiently long time. MIL-101 is reusable for at least five times without any sign of deactivation according to the time-conversion plots. Evidence by electron paramagnetic resonance spectroscopy detecting the hydroperoxide radical adduct with a spin trapping agent and Raman spectroscopy detection of superoxide supports that the process is an auto-oxidation reaction initiated by MIL-101 following the expected radical chain mechanism inside the MIL-101 cages.Financial support by the Spanish Ministry of Economy and Competitiveness (Severo Ochoa and CTQ2012-32315) is gratefully acknowledged.
