4. Particulate air pollution in the heart of the European Union : lessons learned from SAFICA 2017-2018 and SAAERO 2022-2023 projects in Central and Southeast EuropeKatja Džepina, Kristina Glojek, Martin Rigler, Asta Gregorič, Matic Ivančič, Irena Ježek, Griša Močnik, 2024, published scientific conference contribution abstract Abstract: Particularly during the cold weather season, countries of the Southeast Europe are experiencing some of the poorest air quality in the world due to the extensive use of solid fuels and old vehicle fleets. The city of Sarajevo is the capital of Bosnia and Herzegovina (BiH) situated within a basin surrounded by mountains. In the winter months (domestic heating season), topography and meteorology cause the pollutants to be trapped within the city basin. Countries of the Southeast Europe lack state-of-the-art atmospheric sciences research and access to sophisticated instrumentation and methodology, despite high levels of ambient pollution and position within the European Union (EU) borders, making it imperative to understand the emission sources, processing and the adverse health effects of atmospheric aerosol pollution.
This presentation will highlight the field measurements in Central and Southeast Europe during the Sarajevo Canton Winter Field Campaign 2017-2018 (SAFICA) and Sarajevo Aerosol Experiment 2022-2023 (SAAERO) projects, centered at the Sarajevo Bjelave supersite. Both projects were envisioned to produce crucial, not previously available information about aerosol emission sources and atmospheric transformations through a combination of online field and offline laboratory measurements. Online measurements during a) SAFICA and b) SAAERO included, a) black carbon, particle number and size distribution, and b) carbonaceous species, elemental composition and bulk chemical composition. SAAERO online measurements also included stationary and mobile measurements of gas- and particle-phase species on board the mobile laboratory in Sarajevo and Zenica, BiH, as well as in Ljubljana, Slovenia and Zagreb, Croatia. Finally, extended SAAERO project included measurements of black carbon at three additional urban centers: Ljubljana, Zagreb, and Belgrade, Serbia, enabling the first comparison of urban air quality in Central and Southeast Europe between two EU and two non-EU capitals.
During both projects, laboratory aerosol analyses determined aerosol bulk chemical composition, selected elements (Huremović et al., 2020; Žero et al., 2022) and molecular species (Pehnec et al., 2020). Aerosol chemical composition determined by aerosol mass spectrometry was further analyzed by Positive Matrix Factorization to separate organic aerosol into subtypes characteristic of specific sources and atmospheric processes. Aerosol oxidative potential was also determined to evaluate aerosol ability to generate reactive oxygen species. Sarajevo and Belgrade have high ambient loadings of aerosol and black carbon, indicative of strong and diverse combustion sources and a major public health hazard. Finally, aerosol surface concentrations will be discussed in the context of European air quality.

5. The representations of female sexual desire in the works of Zofka Kveder (1878-1926)Katja Mihurko, 2023, published scientific conference contribution abstract Abstract: The paper examines Zofka Kveder's letters to discover the ways in which she depicts her own sexual experiences, including orgasm. Mihurko Poniž will also look for representations of sexual desire in Kveder's literary texts written in Slovenian, German, Czech and Croatian language. The latter show that Kveder was obviously not as open and direct when writing literature. Through the analysis of letters to her friends and journal editors, Kveder's struggles against the censorship of her texts by editors will be presented. These findings will be embedded in the broader historical context of bourgeois double standards and their consequences not only for women in general but for women writers in particular. The issue of (self-)censorship will be touched upon and discussed in the context of Kveder's work. Being in a special position of an author between cultures, Kveder was allowed a certain freedom in the representation of female sexual desire, which would probably not have been possible if she had been perceived only as a Slovenian writer. Therefore, the paper will explore the intersection of nationality, literature, and sexuality in the case of Zofka Kveder’s works and ego-documents.

7. Čustvena pokrajina materinstva in materinjenja v elektronski zbirki PismaKatja Mihurko, 2023, published scientific conference contribution abstract Abstract: Raziskovanje dojemanja materinstva in čustev, ki so se porajala ob materinjenju, je v preteklosti omejeno na pisne vire: sodne zapisnike, publicistične
zapise, literarna dela in ego dokumente. V pismih in dnevnikih so izkušnja
materinjenja in premisleki o njej največkrat izraženi bolj neposredno kot v publicističnih ali literarnih delih. Vendar so ego dokumenti, še posebno t. i. navadnih ljudi, težje dosegljivi, saj se niso tako sistematično ohranjali kot tiskana
besedila in sodni zapisniki. Zato so pisma, ki so objavljena v elektronski zbirki
Pisma, dragocena pričevanja o materinstvu in materinjenju ter z njima povezanimi čustvi ljubezni, veselja, žalosti, jeze in strahu. V prispevku bom predstavila možnosti iskanja vsebin, ki so povezane z materinstvom in materinjenjem
v omenjeni elektronski zbirki. Na osnovi vizualizacij zbirke bom najprej pokazala, s katerimi tematikami se povezuje tematika materinstva in materinjenja v
dopisovanjih avtoric slovenske moderne ter družine Kremenšek Boršnik, nato
pa še kako o tem pišeta meščanka (Ivanka Kremenšek, poročena Boršnik) in
slovenska pisateljica (Zofka Kveder) konec 19. in v začetku 20. stoletja. Keywords: intimnost, materinstvo, spolna želja, korespondence, digitalna humanistika, slovenska moderna Published in RUNG: 11.03.2024; Views: 293; Downloads: 1 Link to file This document has many files! More... |

10. Identification and detailed characterization of ▫$PM_10$▫ sources in an Alpine valley influenced by a cement plantKristina Glojek, Katja Džepina, Griša Močnik, 2023, published scientific conference contribution abstract Abstract: The contribution of traffic and wood burning to particulate matter (PM) across the Alps is widely recognized and studied (Herich et al., 2014 and references therein; Glojek et al., 2020). However, studies on valleys with cement production are scarce (Kim et al., 2003; Rovira et al., 2018) despite its large PM emissions and potential toxic properties (Erik et al., 2022; Weinbruch et al., 2023). We aim to identify and characterize sources’ contribution to the complex mixture of carbonaceous and mineral PM10 in a representative Alpine valley.
Quartz filter samples of PM10 were collected daily from December 2020 to December 2021 and analyzed using different chemical techniques. In the same period equivalent black carbon (eBC) measurements were taken with the Aethalometer AE43. The measured species were analyzed using Positive Matrix Factorization (PMF) model (EPA PMF 5.0) with newly added tracers, i. e. source-specific eBC (Sandradewi et al., 2008) and organic species (2-MT, 3-MBTCA, phtalic acid, MSA and oxalate). The final PMF results were compared to online PMF-factors (SoFi Pro) derived from PM10 and PM2.5 elemental measurements (Cooper Xact 625i).
Ten factors were identified at the site, including commonly detected biomass burning, traffic, nitrate- and sulfate-rich, aged sea salt and mineral dust. With the added additional organic traces, primary biogenic and secondary oxidation were recognized as well. In addition, two unusual factors were disclosed, contributing 10% to annual PM10. Namely, Cl-rich and a mineral dust-rich factor, which we name the cement kiln factor. We associate these two factors to different processes in the cement plant.
The outputs of the study provide vital information about the influence of cement production on PM10 concentrations in complex environments and are useful for PM control strategies and actions.
