11. Sarajevo Canton Winter Field Campaign 2018 : particulate air pollution in a global hotspotKatja Džepina, Vaios Moschos, Anna Tobler, Francesco Canonaco, Deepika Bhattu, Roberto Casotto, Athanasia Vlachou, Jasna Huremović, Sabina Žero, Griša Močnik, 2020, published scientific conference contribution abstract Abstract: Nowadays, urban centres in countries of the Western Balkan region (including Bosnia and Herzegovina (B&H)) are experiencing some of the poorest European and global air quality due to the extensive use of solid fuels (e.g., wood, coal) and old vehicle fleet. Western Balkan countries lack state-of-the-art atmospheric sciences research despite high levels of ambient pollution, which makes the efforts to understand the mechanisms of their air pollution imperative. The city of Sarajevo, the capital of B&H, is situated in a basin surrounded by mountains. Particularly during the winter months, topography and meteorology cause significant pollution episodes.
The Sarajevo Canton Winter Field Campaign 2018 (SAFICA) took place from Dec 04, 2017 to Mar 15, 2018 with on-line aerosol measurements and collection of daily, continuous filter PM10 samples for off-line laboratory analyses. SAFICA aimed to give the first detailed characterization of the Western Balkans aerosol composition including organic aerosol (OA) to elucidate aerosol emission sources and atmospheric processing and to estimate the adverse health effects. PM10 samples (ntotal=180) were collected at four sites in the Sarajevo Canton: a) Bjelave and b) Pofalići (urban background); c) Otoka (urban); d) Ivan Sedlo (remote). The urban sites were distributed along the city basin to study the pollutants’ urban evolution and the remote site was chosen to compare urban to background air masses.
SAFICA PM10 samples underwent different off-line laboratory chemical analyses: 1) Bulk chemical composition of the total filter-collected water-soluble inorganic and OA by a high-resolution Aerodyne Aerosol Mass Spectrometer (AMS). The measured AMS OA spectra were further analysed by Positive Matrix Factorization (PMF) using the graphical user interface SoFi (Source Finder) to separate OA into subtypes characteristic for OA sources and atmospheric processes. 2) Organic and elemental carbon (OC/EC), water-soluble organic carbon, polycyclic aromatic hydrocarbons, levoglucosan, and 14C content of total carbon to evaluate OA chemical composition. 3) Major inorganic anions and cations to evaluate aerosol inorganic species. 4) Metal content in aerosol determined by two analytical techniques (AAS and ICP-MS). SAFICA on-line measurements of black carbon (Aethalometer) and the particle number concentration (Condensation Particle Counter and Optical Particle Sizer) enabled the insights into the daily evolution of primary pollutants and an assessment of aerosol size and number distribution.
The combined SAFICA results for on- and off-line measurements will be presented. Our results show that the carbon-containing species make ~2/3 of PM10 mass and the majority are oxygenated, water-soluble OA species with an average OM/OC = 1.9 (Fig.1). Urban air pollution crises in the Western Balkan will be put in the context of local, regional and global air quality. Finally, we will present the scientific questions opened by SAFICA, including the advantages and limitations of SAFICA data set, and give the recommendations for future studies.

18. The Circular Economy in Adaptive Reuse: Respecting Authenticity and IntegrityMarco Acri, Saša Dobričić, Jukka Jokilehto, 2019, published scientific conference contribution Abstract: One of the main topics of discussion and research at present in the building sector is related to the principles of circular economy in a new global scenario of resilience and sustainability. Given that most of European urban areas and landscapes are considered as cultural, it derives that the circular economy should be also applied to the actions and processes of conservation and valorisation, giving thus new emphasis on the concept of adaptive reuse. Thus, it is not merely an issue of retrofitting historic buildings to respond to energy efficiency parameters, or to adapt them for the climate change threats, but much more: it is about rethinking adaptive reuse of cultural heritage (adaptive in both directions) within and overall sustainable process which intakes reflections on materials, techniques, technologies, praxes, but also policies, businesses, management and governance. This is the effort of the CLIC project, Circular Models leveraging investments in Cultural heritage adaptive reuse, in the Horizon2020 research framework, where the University of Nova Gorica is a partner.
This new approach in a global market economy perspective is strongly looking backwards to the traditional building site mechanisms, techniques and procedures, as matured in logistic and technological constraints. In history though, prior of the enforcing of the conservation theory principles, the aspects of authenticity and integrity were not a reference for the builders as the materials and the technologies were usual, repetitive for centuries, while today they are essential criteria for conservation and reuse. But what does it mean today looking at circular models in adaptive reuse? Adaptive reuse refers to the need to adapt cultural heritage to new needs and uses, but circularity ask also to adapt to the cultural heritage peculiarities and fragilities. May this mean we have an additional ally for the preservation of the integrity and the authenticity, as well as for a new wave in preservation of objects, urban and cultural landscapes?
