Five dimensions allow to understand sustainable development from a multidisciplinary perspective: the geographic, the economic, the ecological, the social and the cultural ones. Different attitudes can be adopted by the gastronomic sector which contribute to a sustainability-focused management. In view of this, the aim of the present article is to discuss the perception of sustainability from the gastronomy industry perspective. For this, in addition to a literature review a quali-quantitative approach was taken through the compilation of a questionnaire which was electronically sent to establishments that form the Campos Gerais gastronomic network in Parana. The current pandemic scenario was taken into account in order to identify attitudes that allowed the establishments to remain operational in the face of the restrictions imposed by Covid-19. Twenty-two of twenty-five associated establishments responded to the survey, most of them showing to have adopted sustainable management actions and, especially regarding the pandemic scenario, adaptations that allowed them to remain in business.

The objective of the article was to examine the relationship of tobacco smoking with the risk of acquiring COVID-19. Gas exchange, lung function, and blood circulation, processes directly affected in COVID-19, improve quickly after smoking cessation. Quitting smoking and avoiding exposure to tobacco smoke and vapors can have a positive impact, reducing the risk involved in COVID-19 and smoking.

Introduction: The COVID-19 pandemic caused by the new coronavirus is a disease without specific treatment and has become one of the great challenges of the current century. One of the alternatives to minimize the direct transmission rate of the virus is the use of face masks. Currently, there is a diversity of masks on the market, both in the textile composition and in the presence or absence of the silver (Ag) element, in the form of ions or silver nanoparticles (AgNP), which have biocidal activity. Objective: To evaluate the presence of total Ag and AgNP in masks produced to protect the population from COVID-19 being sold in Brazil during the pandemic. Method: This is a cross-sectional descriptive observational study with convenience sampling. The samples were analyzed by ICP-MS in the standard mode and in the single particle mode. Results: The concentrations of total Ag in the studied samples varied from 14 to 72 mu gg(-1). It was observed that 50% of the evaluated samples that claim to have AgNP had a size distribution between 17 and 57 nm. When subjected to the washing cycles, there was a reduction in the concentration of Ag, which raises the question as to its real biocidal effectiveness over time. Conclusions: The data generated can provide the current scenario of the concentration of silver in the masks and thus assess the potential benefit or risk of use for human and environmental health. In addition, this knowledge can provide technical-scientific support for the sanitary inspection of quality control and implementation of regulatory standards in this field of activity.
