Proximate and fatty acid profile analysis of Tenebrio molitor and Zophobas morio using different killing methods.

The present work aimed to quantify the macronutrients and the fatty acid (FA) profile in different killing methods, blanching (BC) and freezing (FR), on edible insects of the speciesTenebrio molitor(TM) andZophobas morio(ZM). Concerning macronutrients TM-BC and TM-FR presented 51.2% and 50.6% of protein, 28% and 29.4% of lipids, and 12.4% and 11.4%. Meanwhile, ZM-BC and ZM-FR expressed 42.8% and 43.7% of protein, 39.1% and 40.1% of lipids, and 10.7% and 8.9% of carbohydrates. The FA of TM and ZM shows respectively values of Saturated Fatty Acids (∑SFA) 30% - 45%, Monounsaturated (MUFA) 47% - 32%, Polyunsaturated (∑PUFA) 23% - 22%, Atherogenicity Index (AI) 0.64 - 0.75, Thrombogenicity Index (TI) 0.77 - 1.44 and hypocholesterolemic/hypercholesterolemic index (h/H) of 2.50-1.51. Based on the results obtained, the slaughter methods showed statistically differences in relation to MUFA's in TM, and ZM larvae only in the minority fraction of FA.

Scientometric analysis of the development of plastic packaging considering the circular economy and clean technologies: A review.

Plastics are alternatives to enable the distribution of industrialized products, especially food. Packaging is versatile and of great importance for the conservation of products. However, plastic packaging impacts the environment and calls for a clean technology and circular economy approach to mitigate the damage. A scientometric analysis of the relationship between plastic packaging production and the circular economy was reviewed based on the premise that research is intrinsically linked to clean technologies. VosViewer software was used to conduct the analysis, and the revision was conducted for discussion and relationship building. We concluded that there is a gap regarding the connection between the circular economy and clean technologies with plastic packaging. The development of technologies that adapt plastic packaging to the circular economy is rarely discussed. To make plastic packaging more environmentally attractive, technologies based on eco-design are necessary to achieve an alternative scenario associated with a more sustainable circular economy.

Potential for bifenthrin removal using microalgae from a natural source.

The accumulation of environmental pesticides can cause problems in aquatic ecosystems and adverse effects in humans. These compounds can be found in water due to runoff from agricultural, industrial and domestic applications. In Southern Brazil, tobacco cultivation is one of the most important economic agricultural activities. The bifenthrin pesticide, classified as having moderate toxicity (class II), is commonly used as an insecticide in this culture. In this context, the present research aimed to study the performance of microalgae-induced bioremediation processes. Microalgae were isolated from a natural water source in the city of Santa Cruz do Sul, RS, Brazil, which is an artificial reservoir used for public water supply. For this purpose, biodegradation, biosorption, influence of pH, percentage of inoculum and photoperiod were evaluated in batch experiments for 20 cultivation days. After the phycoremediation process, the bifenthrin pesticide (m/z = 181) was quantified by gas chromatography with mass spectrometry (GC-MS). The results indicated that microalgae isolated from the water of the lake were able to contribute to the removal of approximately 99% of bifenthrin through biodegradation and biosorption processes. Photodegradation was identified (>77%) and the best condition for the phycoremediation was 20% inoculum with a photoperiod of 18:6 h.

Avaliação da qualidade do ar de um centro cirúrgico de um hospital do sul do Brazil / Evaluation of the quality of air in a surgical center of a hospital in the south of Brazil / Evaluación de la calidad del aire de un centro quirúrgico de un hospital del sur de Brasil

Objetivo Avaliar a qualidade do ar das salas do centro cirúrgico de um hospital no Sul do Brasil. Métodos Foi realizada uma avaliação dos parâmetros de confortabilidade (temperatura, luminosidade, concentração de dióxido de carbono e umidade relativa do ar), análise microbiológica e cromatográfica do material particulado presente nos filtros dos aparelhos de ar condicionados. Resultados Em relação aos aspectos de confortabilidade, três salas cirúrgicas não apresentaram temperatura de acordo com a legislação vigente, mas encontram-se dentro do padrão ideal nos demais fatores ambientais. Na análise do material particulado, obteve-se um maior número de bioaerossóis fúngicos de colônias viscosas do que as filamentosas. Conclusões Constatou-se que os principais aspectos da qualidade do ar no hospital são atendidos, no entanto há a necessidade de modificação de aspectos construtivos nas salas de cirurgia para que se reduza a possibilidade de contaminações por via atmosférica e possa reduzir a concentração de dióxido de carbono no ambiente.(AU)

Objective The aim of this study was to evaluate the quality of air in surgical centre rooms of a hospital in the South of Brazil. Methods An evaluation of the parameters of comfortability (temperature, luminosity, concentration of carbon dioxide and relative humidity), microbiological analysis and chromatographic of the particulate material present in the filters of air conditioners was carried out. Results Regarding the aspects of comfortability, three surgical rooms did not present temperature in accordance to the current legislation, but were found within the ideal patterns in other environmental factors. In the analysis of particulate material, a larger number of fungal bio-aerosols of viscous colonies was obtained than filamentous. Conclusion It was found that the main aspects related to the quality of air in the hospital being studied are being accomplished; however there is a need of modifying building aspects in the surgical rooms in order to reduce the possibility of contamination by air and decrease the concentration of carbon dioxide in the environment.(AU)

Objetivo Evaluar la calidad del aire de las salas del centro quirúrgico de un hospital en el "Vale do Rio Pardo", en el sur de Brasil. Métodos Fue realizada una evaluación de los parámetros de confortabilidad (temperatura, luminosidad, concentración de dióxido de carbono y humedad relativa del aire), análisis microbiológico y cromatográfico del material particulado presente en los filtros de los aparatos de aire acondicionados. Resultados En relación a los aspectos de confortabilidad, tres salas quirúrgicas no presentaron temperatura de acuerdo con la legislación vigente, pero se encuentran dentro del padrón ideal en los demás factores ambientales. En el análisis del material particulado, se obtuvo un número más grande de bioaerosoles fúngicos de colonias viscosas de que las filamentosas. Conclusión Se constató que los principales aspectos relacionados a la calidad del aire en el hospital en estudio, son atendidos, sin embargo, ahí la necesidad de cambio de aspectos constructivos en las salas de cirugía para que se reduzca la posibilidad de contaminaciones por vía atmosférica y pueda reducir la concentración de dióxido de carbono en el ambiente.(AU)
