1. Significant fragmentation of disposable surgical masks—enormous source for problematic micro/nanoplastics pollution in the environmentAlen Erjavec, Olivija Plohl, Lidija Fras Zemljič, Julija Volmajer Valh, 2022, original scientific article Abstract: The pandemic of COVID-19 disease has brought many challenges in the field of personal
protective equipment. The amount of disposable surgical masks (DSMs) consumed increased dramatically, and much of it was improperly disposed of, i.e., it entered the environment. For this reason,
it is crucial to accurately analyze the waste and identify all the hazards it poses. Therefore, in the
present work, a DSM was disassembled, and gravimetric analysis of representative DSM waste was
performed, along with detailed infrared spectroscopy of the individual parts and in-depth analysis
of the waste. Due to the potential water contamination by micro/nanoplastics and also by other
harmful components of DSMs generated during the leaching and photodegradation process, the
xenon test and toxicity characteristic leaching procedure were used to analyze and evaluate the
leaching of micro/nanoplastics. Micro/nanoplastic particles were leached from all five components
of the mask in an aqueous medium. Exposed to natural conditions, a DSM loses up to 30% of its mass
in just 1 month, while micro/nanoplastic particles are formed by the process of photodegradation.
Improperly treated DSMs pose a potential hazardous risk to the environment due to the release of
micro/nanoparticles and chloride ion content.
Keywords: DSM, micro/nanoparticles, leaching, artificial weathering, environmental pollution

2. Analytical gas sensing in the terahertz spectral rangeAndreja Abina, Uroš Puc, Mojca Jazbinšek, Aleksander Zidanšek, 2023, original scientific article Abstract: Exploiting the terahertz (THz) part of the electromagnetic spectrum is attracting attention in various scientific and applied disciplines worldwide. THz technology has also revealed its potential as an effective tool for gas analysis in astronomy, biomedicine and chemical analysis. Recently, it has also become important in environmental applications for monitoring hazardous and toxic gases in the atmosphere. This paper gives an overview of THz gas detection analytical methods for environmental and biomedical applications, starting with a brief introduction to THz technology and an explanation of the interaction of THz radiation with gaseous species and the atmosphere. The review focuses on several gaseous species and groups of air pollutants that have been or can be analysed by THz spectrometry. The review concludes that different but complementary THz detection methods allow unique detection, identification and quantification of gaseous and particulate air pollutants with high selectivity, specificity and sensitivity. THz detection methods also allow further technological improvements and open new application possibilities.
Keywords: terahertz spectroscopy, gas sensing, air pollution, environmental monitoring

3. Reviewing the narrative concerning the impact of population growth in AfricaCocou Marius Mensah, 2019, original scientific article Abstract: This article discusses the topic of population growth in Africa, a recurring theme in the era of climate change and the fight against CO2 emissions. The African continent is full of essential raw materials and encompasses the youngest population in the world. There is no doubt concerning the significant role it will play in global affairs, at a time when the world population is ageing, according to the UN statistics. In recent years, many policymakers have highlighted the necessity to deal with overpopulation, provoking moral controversial and basic human rights abuses. This article, however, proposes an opposite argumentation based on fresh data and emphasises the opportunities and challenges to take on, as the author considers "overpopulation" as more of a challenge than a sentence to underdevelopment. Though the paper mentions different issues linked to overpopulation, such as migration crisis, ecological sustainability and the UN Sustainable Development Goals, it concludes with a reminder of the importance of international cooperation as a solution to global issues.
Keywords: global issues, impact of population growth, migration trends, international cooperation, pollution, African Union, European Union, UN sustainable development goals, environmental footprint

6. Environmental management & audit 4: Environmental assessment - featured articles : Tempus project Recoaud2016, scientific monograph Abstract: The present scientific monograph, entitled “Environmental management & audit“, is the result of three years’ work on an international project entitled “Environmental management in Russian companies – retraining courses for the sensibilization for and integration of Eco-Audit programs in corporate decision-making (RECOAUD)”. Within its more than 600 pages, the monograph features interesting texts written by 31 authors from the European Union and the Russian Federation, edited by dr. Borut Jereb, Darja Kukovič and dr. Daria Meyr.
The monograph “Environmental management & audit“ is composed of four books: “Scarcity and Introduction of Environmental Management”, “Management Systems”, “Controlling and Stakeholders”, and “Environmental Assessment” (Featured Articles). These four topics reflect the complexity, heterogeneity and multidisciplinary of the project Tempus RECOAUD.
The reader of the monograph gets a comprehensive overview of theoretical perspectives of environmental management and audit in the chosen areas. Furthermore, the monograph also highlights the results of research in the field of environmental management and audit as well as trends and challenges in the development of this field. Providing insight into theoretical and research findings, the monograph will prove useful to both practitioners and researchers in the field of environmental management and audit; it can also be used for study purposes.
Keywords: logistics, environment, climate change adaptation, sustainability, reverse logistics, life cycle assessment, environmental impact assessment, waste management, oil industry, gas industry, pollution
