Particulate matter air pollution in the Republic of Slovenia and its national spatial emissions release
Petra Dolšak Lavrič, Maja Ivanovski, Darko Goričanec, Danijela Urbancl, 2023, original scientific article

Abstract: In this work, an impact of particulate matter (PM) on air pollution and its emissions released is investigated. Concentration levels of PM10 and PM2.5 in the Republic of Slovenia (RS) were analyzed on daily, weekly, monthly, quartile, and annual data and then compared. The study was conducted from January 1, 2020 to December 31, 2020 at two monitoring stations, so-called urban traffic and urban industrial. Obtained results showed that the highest concentrations of PM in air were during the cold months of the year when the temperatures are lower (< 6%). Results from heating seasons (from October 1, 2019 and March 31, 2020 and from October 1, 2020 to March 31, 2021) showed the highest concentration levels of PM10 between 9:00 and 14:00 and between 18:00 and 22:00, with highest concentrations recorded during the winter months (January and February). Additionally, emission building inventory was built based on PM10 and PM2.5 emissions released. The study includes yearly spatial building emissions release model considering currently installed high PM emitted stoves. The building model for the Republic of Slovenia has been developed by using 500 x 500 m model grid. Obtained results showed that changing currently low efficient appliance with advanced appliance would result in significant lower PM emissions released from building sector

Analytical gas sensing in the terahertz spectral range
Andreja 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.

Assessment of Air Pollution in Different Areas (Urban, Suburban, and Rural) in Slovenia from 2017 to 2021
Maja Ivanovski, Kris Alatič, Danijela Urbancl, Marjana Simonič, Darko Goričanec, Rudi Vončina, 2023, original scientific article

Abstract: Air pollution can have a significant effect on human health. The present work is focused on the investigation of daily, monthly, and annual concentration levels of five typical air pollutants (SO2, NO2, NOX, PM10, and PM2.5) in the Republic of Slovenia (RS) from January 2017 to December 2021. The study was conducted at five different monitoring stations of the following kind: traffic (A), industrial (D), and background (B, C, E). The obtained results showed a decline in the average concentrations for all the studied air pollutants through the years, respectively. The daily average SO2 concentrations were the lowest in the year 2021 at location B, which is classified as background location, while the highest were detected in the year 2018 at location E, which is also classified as background location. The average daily concentrations of NO2 and NOX were the highest at location A in the year 2017, whereas the lowest were detected in the year 2010 and 2021. It is believed that those results are a consequence of measures set by the Slovenian government during the COVID-19 pandemic. The PM10 and PM2.5 daily average concentrations were the highest at location A in 2017, while the lowest were observed in the year 2019 at location C. Meteorological parameters (temperature, wind speed, and relative humidity) were studied in addition. In general, the high temperatures in ambient air are responsible for the intense concentrations of air pollutants. It was found in the study results for temperature, wind speed, and relative humidity that no significant difference was shown between studied years.

Reviewing the narrative concerning the impact of population growth in Africa
Cocou 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

Corrosion mechanisms for cemented soils in three different sulfate solutions
Pengju Han, Chao Ren, Xiaohong Bai, Frank Chen, 2015, original scientific article

Abstract: In order to simulate and study the corrosion effects on the compressive strength of cemented soils that could be exposed in a polluted environment, a series of tests were conducted on cemented soil blocks cured with different concentrations of H2SO4, MgSO4, and Na2SO4 solutions. The test results show that the corrosion degree generally increases with the corrosion time and the solution concentration, while the compressive strength decreases with the increasing corrosion degree. The corrosion degree is highest for the Na2SO4 solution, followed by the MgSO4 and H2SO4 solutions. Namely, when the SO4 2- ion exists in a solution, the corrosion degree for the positive ions follows this descending order: Na+, Mg2+, and H+. X-ray diffraction (XRD) phase analyses were performed for the cemented soil samples after corrosion and ionic concentrations. The results show that the compressive strength decreases with an increase of the Mg2+ concentration in the MgSO4 solution and the Na+ concentration in the Na2SO4 solution. At the same time, the strength increases with an increase of the pH value of the H2SO4 solution. Based on the chemical analysis results, the corrosion of H2SO4 or MgSO4 solutions on cemented soils is deemed as a composite action involving the combined resolving and crystallizing corrosion processes. Furthermore, the corrosion of the Na2SO4 solution of cemented soil is a composite action consisting of dissolving and crystallizing.

Management of soil as a natural resource in the Savinjska statistical region in Slovenia
Milena Petauer, 2010, review article

Abstract: Animals, plants and microorganisms could not exist without soil, because without it life on Earth would not be possible. Thus we should always be concerned with preserving the soil condition. This should be a personal, a municipal, as well as a national concern. Nevertheless, the role of soil is not sufficiently incorporated into the planning of sustainable development of the Savinjska statistical region, therefore more active approaches are needed in the field of soil management and protection (education, research, raising public awareness, soil protection programs, soil related educational excursions, etc.).
Keywords: pedogeography, natural resources, soil pollution, land use, Slovenia
