- Pharmaceuticals in the Environment: Focus on Drinking-WaterPublication . Teixeira-Lemos, Edite; Teixeira De Lemos, Luís Pedro; Oliveira, Jorge; Pais do Amaral, JoséAbstract The presence of pharmacological compounds in drinking water has been a cause for concern in recent years and are believed to have serious impacts on human and environmental health. Current research has shown that they can pose an ecotoxicological risk due to their potential long-term negative effects on living organisms, even though they exist in relatively low concentrations in drinking water (ng L− 1). This article is a review of the most important available literature on pharmaceutical residues in water cycle, focusing mostly on drinking water. The authors start by approaching the occurrence and fate of pharmacological compounds in drinking waters, with a particular emphasis on the pharmacological classes which are more frequently detected. Then, existing processes to remove these xenobiotics from drinking waters and analytical detection methods are also explored, followed by an analysis of the ecotoxicity and potential risks for human health of exposure to trace amounts of pharmaceuticals in drinking water. Finally, after examining existing legislation regarding pharmaceuticals in drinking water, namely the European Union regulatory frameworks, the authors discuss future perspectives in research, social, and legislative measures on this matter are discussed in light of the currently identified gaps in both scientific knowledge and legislation.
- Is Better Knowledge about Health Benefits of Dietary Fiber Related to Food Labels Reading Habits? A Croatian OverviewPublication . Ljubičić, M.; Sarić, M. M.; Rumbak, I.; Barić, I. C.; Sarić, A.; Komes, D.; Šatalić, Z.; Dželalija, B.; Guiné, Raquel P. F.The aim of this cross-sectional study was to determine the associations between health dietary patterns, knowledge, and consumption of dietary fiber (DF) with frequency of food label reading on food products with special reference to DF. The study was conducted in 2536 Croatian adults using an original questionnaire. Multiple linear regression models were used to assess associations between food label reading habits and predictor variables. Our study confirms the association between habits regarding the reading of labels on food products, especially in relation to information about DF with the sociodemographic factors of respondents, dietary food patterns and DF consumption, as well as knowledge and sources of information about DF. Women, individuals with a university-level education, and those living in an urban environment had more frequent labels used. Food habits as well as eating outside of the home were positive predictors while eating fast food was a negative predictor of food label reading. Knowledge about DF, especially about its health benefits, was also associated with food label reading. The interpretation of associations could help with the design of effective public health programs. Targeted education campaigns to educate and sensitize the population about food labeling and monitoring may improve general knowledge about healthy food and its benefits, which include indirect effects on the prevention of non-communicable chronic diseases.

- Investigation of the Level of Knowledge in Different Countries about Edible Insects: Cluster SegmentationPublication . Guiné, Raquel P. F.; Florença, S. G.; Costa, Cristina Amaro Da; Correia, Paula; Ferreira, Manuela; Cardoso, Ana Paula; Campos, Sofia; Anjos, Ofélia; Chuck-Hernández, C.; Sarić, M. M.; Djekic, I.; Papageorgiou, M.; Baro, J. M. F.; Korzeniowska, M.; Černelič-Bizjak, M.; Bartkiene, E.; Tarcea, M.; Boustani, N. M.; Klava, D.; Damarli, E.This study aimed to investigate the level of knowledge about edible insects (EIs) in a sample of people from thirteen countries (Croatia, Greece, Latvia, Lebanon, Lithuania, Mexico, Poland, Portugal, Romania, Serbia, Slovenia, Spain, and Turkey). Data collection was based on a questionnaire survey applied through online tools between July and November 2021. For data analysis, techniques such as factor analysis, cluster analysis, and chi-square tests were used, with a significance level of 5%. A total of 27 items were used to measure knowledge on a five-point Likert scale. Applying factor analysis with principal components and Varimax rotation, a solution that explains about 55% of variance was obtained. This accounts for four factors that retained 22 of the 27 initial items: F1 = Sustainability (8 items), F2 = Nutrition (8 items), F3 = Production Factors (2 items), and F4 = Health Concerns (4 items). Internal consistency was evaluated through Cronbach’s alpha. The cluster analysis consisted of the application of hierarchical methods followed by k-means and produced three clusters (1—‘fearful’, 2—‘farming,’ and 3—‘ecological’ individuals). The characterisation of the clusters revealed that age did not influence cluster membership, while sex, education, country, living environment, professional area, and income all influenced the composition of the clusters. While participants from Mexico and Spain were fewer in the ‘fearful’ cluster, in those from Greece, Latvia, Lebanon, and Turkey, the situation was opposed. Participants from rural areas were mostly in cluster 2, which also included a higher percentage of participants with lower income. Participants from professional areas linked with biology, food, and nutrition were mostly in cluster 3. In this way, we concluded that the level of knowledge about EIs is highly variable according to the individual characteristics, namely that the social and cultural influences of the different countries lead to distinct levels of knowledge and interpretation of information, thus producing divergent approaches to the consumption of insects—some more reluctant and measuring possible risks. In contrast, others consider EIs a good and sustainable protein-food alternative.
- Professional Training in Beekeeping: A Cross-Country Survey to Identify Learning OpportunitiesPublication . Guiné, Raquel P. F.; Oliveira, Jorge; Coelho, Catarina; Costa, Daniela; Correia, Paula; Esteves Correia, Helena; Dahle, B.; Oddie, M.; Raimets, R.; Karise, R.; Tourino, L.; Basile, S.; Buonomo, E.; Stefanic, I.; Costa, Cristina Amaro DaHabitat loss, climate change, and other environmental degradations pose severe challenges to beekeepers. Therefore, this sector needs to rely on updated information so that the intervening actors can deal with the problems. In this context, and assuming that professional training can greatly help those acting in the beekeeping sector, this work intended to investigate the gaps in the updated knowledge of beekeepers and how these can be filled through lifelong learning. The research was conducted in seven European countries (Croatia, Estonia, Finland, Italy, Norway, Portugal, and Spain). The data were collected through a questionnaire survey translated into the native languages of all participating countries. The results revealed that the topics of highest interest are apiary health and pest control and the management of the colonies throughout the year. The beekeepers update their knowledge through family, complemented by professional training, with participants preferring in-person courses as well as, in the workplace or in internships. The learning methodologies they consider most useful are project-based learning and learning through gamification. The videos and paper books or manuals are particularly valued as learning materials, and practical exercises are considered the most helpful assessment format. Finally, considering the effect of sociodemographic variables on the learning experiences and preferences of beekeeping actors, it was observed that the country was the most influential of the variables under study. In conclusion, this work revealed valuable information that should be used to design professional training actions to help the professionals in the beekeeping sector enhance their competencies and be better prepared to manage their activities successfully.

- Drying of Aromatic Plants: Processes and EffectsPublication . Silva, Aida; Barroca, Maria João; Florença, Sofia De Guiné E; Bartkiene, Elena; Castelão, David; Guiné, RaquelAromatic plants have been used since ancient times, and traditionally they have been preserved through drying in order to extend their shelf life. The oldest way to dry foods, also applied to aromatic plants and medicinal herbs, was sun drying in open air. However, due to the development of industrial processing technologies, the drying methods evolved and in the present, modern technologies are used as a way to efficiently obtain the products while at the same time looking for the highest possible quality, i.e., preserving the aroma compounds (mostly highly volatile molecules) and also the possible bioactive molecules which provide additional value to the aromatic plants. In fact, there is a thin line between the aromatic plants and the medicinal herbs, which in many cases refer to the same plant. In view of this, the present chapter aims to address the drying procedures and corresponding operational conditions and their effects on the quality of dried aromatic plants.
