Every day, there is an increase in environmental damage on the planet regarding human action. One of the causes is food production. Edible insects are presented as an option to mitigate the environmental damage generated by the production of conventional food for humans and animals. The objective of this study was to investigate the main nutritional aspects of insects and how they can provide a nutritional and sustainable alternative to the planet. As the main results, the nine orders of insects that are most consumed on the planet are presented: Blattodea, Coleoptera, Diptera, Hemiptera, Hymenoptera, Isoptera, Lepidoptera, Odonata, and Orthoptera. Their main macro- and micronutrient aspects as well as their bioavailable and bioaccessibility proteins and essential amino acids, monounsaturated fatty acids, minerals, vitamins, and fiber (chitin) are also explored. Additionally, some of the species that are used for animal food processing and the possible risks that insects can present when used as food are discussed. With this, edible insects are established as a real option to mitigate climate change being an important nutritional source for the development of food for humans and animals.

Essential oils are highly appreciated by the cosmetics industry because they have antimicrobial and antioxidant properties, among others. Since essential oils are natural products, their inclusion in cosmetic formulations is a common practice. Currently, low-quality and/or adulterated essential oils can be found on the market; therefore, analytical methods for control are required. Raman spectroscopy is a versatile technique that can be used for quality control tasks; the portability of modern devices expand the analytical possibilities also to in situ measurements. Fifteen essential oils of interest for the cosmetics industry were measured using a handheld Raman spectrometer, and the assignment of the main bands observed in their average spectra was proposed. In most cases, it is possible to distinguish the essential oils by a simple visual inspection of their characteristic Raman bands. However, for essential oils extracted from closely-related vegetable species and containing the same main component in a very high proportion, the visual inspection of the spectra may be not enough, and the application of chemometric methods is suggested. Characteristic Raman bands for each essential oil can be used to both identify the essential oils and detect adulterations.

Plant diseases have a direct impact on the productivity of crops, and therefore the early detection of diseases is crucial. Abutilon mosaic virus (AbMV) (family Geminiviridae; genus Begomovirus) is an important virus infecting ornamental crops throughout the world. Abutilon hybridum showing bright yellow mosaic symptoms were observed in gardens in Tumbaco, Ecuador. The infection was confirmed by Polymerase Chain Reaction (PCR) using degenerate begomovirus primers. The amplicon (∼500 bp) was sequenced, submitted to NCBI (KP877621) and showed 68.7–100% and 72.7–100% sequence identity with other begomoviruses at nucleotide and amino acid levels, respectively. In order to evaluate Raman spectroscopy as a diagnostic tool for AbMV infection, spectra of leaves from healthy and infected plants were recorded. Raman signals of carotenoids are the most important features and there is a significant decrease in the intensity of these bands when the plant is infected. The difference in the intensity of the bands, particularly the one at 1526 cm−1, is proposed as a basis for the early detection of viral infection in plants.

Airborne micro and nanoplastics (MPs/NPs) are a growing issue due to their possible health hazards. Since the current bibliography lacks a thorough evaluation, this review examines the sources, environmental dynamics, and health impacts of airborne MPs/NPs. Through atmospheric transport processes, these neo-pollutants spread around the world after being released, potentially settling in urban and remote areas. This review is the first to compare active and passive aerosol sampling methods, and microscopy, thermochemical, and spectroscopy analytical techniques, with a focus on their limitations in precisely quantifying micro-nanoscale plastic particles. It also draws attention to the potential toxicological effects of inhaled MPs/NPs, which can lead to oxidative stress, respiratory inflammation, and other negative health consequences. This review concludes by examining how airborne MPs/NPs may worsen their ecological impact by serving as carriers of hazardous chemicals and microbial pollutants. Despite growing awareness, there still are many unanswered questions, especially about the impact of long-term exposure and how atmospheric conditions affect the spread of MPs/NPs. The aim of this review was to bring attention to the issue of airborne MP/NP effects and to promote the development of advanced monitoring systems, a new multidisciplinary scientific field for the study of these novel pollutants, and global regulatory frameworks.
