Existe a ideia generalizada de que em Évora (Sul de Portugal) as pessoas não gostam da água da torneira, embora a análise da água cumpra os limites estipulados pela legislação. Neste trabalho, através da análise sensorial da água destinada ao consumo humano, pela população de Évora, é possível confirmar esta ideia, perceber motivos, detetar problemas e sugerir melhorias. Para isso, foi realizado um teste cego, em que a população foi convidada a provar diferentes águas, engarrafadas e da torneira, e a responder a um questionário. Este teste foi feito numa atividade apresentada na Feira de São João, a 28 de junho de 2017, e a participação e entusiasmo da população de Évora levou-nos a aprofundar este assunto. Para aumentar o número de respostas e clarificar a perceção das características da água da torneira, foram também envolvidos estudantes universitários e crianças em idade escolar de Évora. Constatou-se que a maioria dos participantes (90%) preferiam e consumiam água engarrafada, apesar de nas crianças da escola básica esta percentagem ser menor (60%). Por último, A análise sensorial permitiu detetar características na água que precisam de ser corrigidas, como a presença do sabor a mofo na água da torneira, em especial no centro histórico de Évora, que indica a presença de geosmina. A presença de cloro residual na água da torneira, e respetivo cheiro, também se revelaram um problema, mascarando o sabor e causando a rejeição do consumo da água para beber.

A crioconcentração é uma técnica verde de conservação de alimentos. O criodiluído do suco de uva é uma alternativa alimentar saudável constituído de água, minerais, açúcares e compostos bioativos naturalmente elaborados pela videira. Assim, objetivou-se avaliar o uso do criodiluído do suco de uva como bebida.

Abstract: The accelerated and disorganized deforestation in Central Brazil and the transformation of these natural ecosystems into crop land or pastures, without adequate technologies, resulted in irrecoverable damages to the environment, especially with respect to water and soil conservation, with particular mention to compactation. As a consequence, the soil intake rate decreased and surface runoff increased, thus causing laminar erosion, low soil quality, silting up of rivers, floods and decreased sustainability of family properties. With the objective of reverting this scenario, a demonstrative unit was implemented in Sete Lagoas MG, in 1995, in a property of 70 ha, where 30 micro-cachments ("barraginhas") were built to contain surface runoff damages.These micro-cachtments also retain pollution sources carried by the waters and favor the recharge of good quality water tables, by means of improving soil intake rate, recovering water sources and alleviating droughts. Due to the success of this demonstration unit, by means of field visits by farmers, NGO´s and publication of articles in journals and national/international congresses, a decision was taken to extend the experience and build 960 low-cost micro-catchments, in 1998, in 60 small properties covering all the micro-basin of the Paiol stream, in the village/community of Estiva, Sete Lagoas county. That was only possible because of the active participation of small farmers in the indication of existing degraded sites and the support provided in terms of food and lodging for the working teams As a result, it is now possible to hear the farmers testimonials on the effects observed in elevation of water tables observed in their domestic reservoirs ("cisternas"), better utilization of the water and drought alleviation, that have increased their yields.

Modern agriculture relies on the use of pesticides to increase food production and meet the needs of a growing population. However, inappropriate use of pesticides can have a significant impact on aquatic ecosystems, as they can enter surface waters or leach into groundwater. This poses a risk to public health since these compounds are persistent and mobile in water sources used for drinking water production. In this context, an investigation was carried out in the Azuero peninsula, to analyze samples of drinking water and groundwater used for consumption. Samples were collected during the rainy season in September 2022 and the dry season in April 2023. EPA Method 525.2 was carried out to detect 17 pesticides using solid phase extraction (SPE) and gas chromatography coupled with mass spectrometry (GC-MS). The results indicated the presence of pendimethalin, atrazine, and its metabolite atrazine-desethyl at low concentrations in drinking water samples in the districts of La Villa de Los Santos and Parita, as well as in groundwater in Santa María. However, the concentrations detected were below the permissible limits according to Panamanian regulations (Technical Regulation DGNTI - COPANIT 21-2019) for drinking water. | La agricultura moderna se apoya en el uso de plaguicidas para incrementar la producción de alimentos y satisfacer las necesidades de una población en constante crecimiento. Sin embargo, el uso inadecuado de plaguicidas puede tener un impacto significativo en los ecosistemas acuáticos, ya que pueden ingresar a las aguas superficiales o filtrarse en las aguas subterráneas. Esto plantea un riesgo para la salud pública, puesto que estos compuestos son persistentes y móviles en las fuentes de agua utilizadas para la producción de agua potable. En este contexto, se realizó una investigación en la península de Azuero, con el objetivo de analizar muestras de agua potable y subterráneas que son utilizadas para consumo. Las muestras se recolectaron durante la temporada de lluvias en septiembre de 2022 y la temporada seca en abril de 2023. Se aplicó el Método EPA 525.2 para detectar 17 plaguicidas utilizando extracción en fase sólida (SPE) y cromatografía de gas acoplada a espectrometría de masas (GC-MS). Los resultados indicaron la presencia de pendimentalina, atrazina y su metabolito atrazina-desetil en concentraciones bajas en muestras de agua potable en los distritos de La Villa de Los Santos y Parita, así como en aguas subterráneas en Santa María. Sin embargo, las concentraciones detectadas estuvieron por debajo de los límites permitidos según la normativa panameña (Reglamento Técnico DGNTI – COPANIT 21-2019) para el agua potable.

Aquatic insect fauna remains an important tool for bio indication of environmental disturbance, while maintaining a healthy aquatic system. The purpose of the study was to document and to identify the diversity and distribution patterns of aquatic insect, a highly ignored aspect from the Qatar. Following the standard procedures, the samples were collected from aquatic habitats during the period October 2015 to May 2017 on monthly basis. A total of 11,287 individuals, belonging to 6 orders were captured. Dipterans were the abundant with the percentages of 71.01 (n=8,015), while the lowest percentage was observed for Coleoptera 0.04 (n=05). Twelve insects families were identified, among these five were reported under Diptera, followed by Hemiptera (03), while Coleoptera, Tricoptera, Odonata, and Ephemeroptera were represented by single families. Among the selected localities, Dipterans were collected from 10 stations, followed by Hemiptera (9), Coleoptera (4), Odonota (4), Ephemeroptera (3) and Trichoptera (1) respectively. Among the water bodies samples, streams were the most preferred habitats (n=2,767), while drinking water pools were the least (27). Moreover, the highest Simpson diversity index of 1.48 and lowest of 0.47 was recorded for flooded sewage pool and plastic containers respectively, while the low evenness values were observed for ponds, and less than 1 Margalef's diversity values were seen for all habitats. This study documents the patterns of the diversity and distribution of aquatic insects, and provides a baseline for the future studies from Qatar. 2024, Instituto Internacional de Ecologia.
