11. Vzgoja in izobraževanje v slovenskem jeziku v ItalijiMaja Melinc Mlekuž, 2022, objavljeni strokovni prispevek na konferenci Opis: Prispevek predstavlja izhodišča za razpravo o jezikovnih smernicah in učnih ciljih v vrtcih in šolah s slovenskim učnim jezikom v Tržaški in Goriški pokrajini ter v večstopenjski šoli s slovensko-italijanskim dvojezičnim poukom v Špetru. Izhaja iz rezultatov kvantitativne raziskave o poteku pouka na daljavo med epidemijo covid-19, izvedene med pedagoškim kadrom, dijaki in
starši otrok, ki obiskujejo vrtce in šole s slovenskim učnim jezikom in dvojezičnim slovensko-italijanskim poukom v Italiji. Izsledke dopolnjuje analiza petnajstih polstrukturiranih globinskih intevjujev z učitelji o didaktično-metodičnih izzivih pri poučevanju učencev, katerih prvi ali primarni jezik ni slovenski, slovenščina pa tudi ni jezik okolja, v katerem živijo.

20. The impact of temperature inversions on black carbon and particle mass concentrations in a mountainous areaKristina Glojek, Griša Močnik, Honey Dawn C.

While there is a significant number of studies conducted in deep urbanized valleys and basins, little is known about the air pollution processes in rural shallow hollows, where around 30 % of the people in mountainous areas across Europe live. We aim to determine the influence of ground temperature inversions on wood combustion aerosol pollution in hilly, rural areas. The study uses Retje karst hollow (Loški Potok, Slovenia) as a representative site for mountainous and hilly rural areas in central and south-eastern Europe with residential wood combustion. Sampling with a mobile monitoring platform along the hollow was performed in December 2017 and January 2018. The backpack mobile monitoring platform was used for the determination of equivalent black carbon (eBC) and particulate matter (PM) mass concentrations along the hollow. To ensure high quality of mobile measurement data, intercomparisons of mobile instruments with reference instruments were performed at two air quality stations during every run. Our study showed that aerosol pollution events in the relief depression were associated with high local emission intensities originating almost entirely from residential wood burning and shallow temperature inversions (58 m on average). The eBC and PM mass concentrations showed stronger associations with the potential temperature gradient (R2=0.8) than with any other meteorological parameters taken into account (ambient temperature, relative humidity, wind speed, wind direction, and precipitation). The strong association between the potential temperature gradient and pollutant concentrations suggests that even a small number of emission sources (total 243 households in the studied hollow) in similar hilly and mountainous rural areas with frequent temperature inversions can significantly increase the levels of eBC and PM and deteriorate local air quality. During temperature inversions the measured mean eBC and PM2.5 mass concentrations in the whole hollow were as high as 4.5±2.6 and 48.0 ± 27.7 µg m−3, respectively, which is comparable to larger European urban centres.
