Pautas de consumo y efectos del alcohol en Instagram en tiempos de COVID-19

Introducción: Compartir “eventos de la bebida” se ha convertido en una práctica habitual entre las personas jóvenes en redes como Instagram. La pandemia por el Covid-19 ha reestructurado tanto sus pautas de consumo de alcohol, como los usos que hacen de las redes sociales. Objetivos y Métodos: Describir en profundidad las pautas de consu- mo de alcohol y los efectos de este consumo que se muestran en Instagram en una muestra de 118 jóvenes y ado- lescentes en España a través de la etnografía digital. Resultados y Conclusiones: Instagram es parte de la fiesta, parte imbricada en la vida cotidiana de las personas jóvenes, en la que se comparten regularmente imágenes deseables de las pautas de consumo de alcohol y sus efectos. Adolescentes y jóvenes construyen un modelo online idealizado de pautas de consumo de alcohol en el que sólo son visibles los efectos de la fase de desinhibición tras el consumo y se obvian el resto de las fases de los efectos del alcohol en el organismo. Es fundamental incluir estas nuevas formas de transmisión de las pautas de consumo de alcohol en la normativa española que regula la venta y uso de alcohol.Introduction: Sharing “drinking events” has become a common practice among young people on Instagram. The Covid-19 pandemic has restructured both their alcohol consumption patterns and their use of social networks. Ob- jective and Methods: To describe in depth the patterns of alcohol consumption and the effects of this consumption shown on Instagram in a sample of 118 young people and adolescents in Spain through digital ethnography. Results and Conclusions: Instagram is part of the party, part embedded in the daily lives of young people, in which desirable images of drinking patterns and their effects are regularly shared. Adolescents and young people build an idealized online model of alcohol consumption patterns in which only the effects of the disinhibition phase after consumption are visible and the rest of the phases of the effects of alcohol on the body are ignored. It is essential to include these new forms of transmission of alcohol consumption patterns in the Spanish regulations that regulate the sale and use of alcohol.Esta investigación está financiada por el Ministerio de Ciencia e Innovación.

Luminescent complexes of iridium(iii) with aliphatic amines and detection of biogenic amines

The straightforward reaction of [Ir2(ppy)4(µ-Cl)2] with an excess of aliphatic amines yields luminescent iridium complexes of general formula [IrCl(ppy)2(amine)] [amine = n-octylamine (1), t-butylamine (2), piperidine (3)]. The higher sterical hindrance of the amine in complex 2 was the responsible of its equilibrium with the starting materials. The luminescence of 1 and 3 has been studied showing emission at 508 and 509 nm respectively. As the aliphatic amines can be considered models of biogenic amines, this luminescence has been used to explore the viability of this reaction in the detection of biogenic amines. The exposition to vapors of biogenic amines of a solution of [Ir2(ppy)4(µ-Cl)2] in CH2Cl2 or in different solid supports, showed that it was possible to detect the amines in a quick and easy way, with limits of detection value (in solution of methylene chloride) of 4.8 µM for cadaverine.Ministerio de Economía y Competitividad, Spain (Project CTQ2015-71353-R), Junta de Castilla y León, Consejería de Educación y Cultura y Fondo Social Europeo (Project BU263P18) and Junta de Castilla y León, Consejería de Educación (Project BU087G19

Protecting effect of recycled urban wastes (sewage sludge and wastewater) on ryegrass against the toxicity of pesticides at high concentrations

Degraded landscapes, like those from abandoned mine areas, could be restored by revegetating them with appropriate plant species, after correction for acidity and improvement by adding exogenous organic material. Application of urban wastes to large areas of derelict land helps in the sustainable development of this landscape. However, the development of plant species in these soils could require in the future the management of possible pests or diseases by pesticide applications which could also affect plant yield. Therefore, ryegrass (Lolium perenne L.) was planted in a limed soil from the mining area of Riotinto (SW Spain), using an indoor pot experiment and the effects of amendment with sewage sludge, as well as irrigation with urban wastewater on plant uptake of the insecticide thiacloprid and the fungicide fenarimol were examined. Ryegrass biomass was reduced up to 3-fold by pesticide application. Fenarimol residues were the highest in soil, while those of thiacloprid were lower in soil and higher in ryegrass. Addition of sewage sludge and irrigation with wastewater led to a reduction of pesticide translocation to the aerial plant parts, representing a lower hazard to ryegrass quality grown in this mine soil.Junta de Andalucía P10-RNM581

Improving the mining soil quality for a vegetation cover after addition of sewage sludges: Inorganic ions and low-molecular-weight organic acids in the soil solution

We assessed the effects of applying stabilized sewage sludge (SSL) and composted sewage sludge (CLV), at 5 and 10% to an acid mining soil. Limed soil (NCL) amended or not with SSL and CLV was incubated for 47 days. We studied the cations and organic and inorganic anions in the soil solution by means of ion chromatography. Liming led to big increases in Ca2+ and SO42- and to significant decreases in K+, Mg2+, NH4+ and NO3-. Addition of both organic amendments increased some cations (NH4+, K+, Mg2+, Na+) and anions (Cl-, NO3- only with CLV and PO43- only with SSL) and provided a greater amount of low-molecular-weight organic acids (LMWOAs) (SSL more than CLV). Incubation led to decreases in all cations, particularly remarkable for Ca2+ and Mg2+ in SSL-10. A decrease in NH4+ was associated with variations in NO2- and NO3- resulting from nitrification reactions. During incubation the LMWOAs content tended to decrease similarly to the cations, especially in SSL-10. Chemometric tools revealed a clear discrimination between SSL, CLV and NCL. Furthermore, treatment effects depended upon dose, mainly in SSL. Amendment nature and dose affect the quality of a mining soil and improve conditions for plant establishment.Junta de Andalucía P10-RNM- 581
