20.500.12556/RUL-160123 Natural and anthropogenic impact on the microclimate and particulate matter in the UNESCO show cave Particulate matter concentrations (PM$_{10}$, PM$_{2.5}$, PM$_1$) and microclimatic parameters (air temperature, CO$_2$) were monitored in the Škocjan Caves (Slovenia). The effects of tourist visits on the PM concentrations and the cave’s microclimate are immediate and direct, but these values normalise relatively quickly. The results showed seasonal, diurnal, and spatial differences in all parameters studied. Due to the higher number of visitors, their influence on the cave’s microclimate and PM$_{10}$ and PM$_{2.5}$ concentrations is greater in summer than in winter. The measured PM$_1$ levels depend on the ventilation in the cave, as air transport plays an important role in their introduction into the cave. PM consists of minerals of natural origin resulting from the re-suspension of cave sediments due to strong air currents generated by the opening of the doors to tourists and their walks. The second most common influence is the anthropogenic phases originating from maintenance work in the cave, electronic devices, cave lighting and emissions from outside the cave (aerosols from the polluted Reka River, industry, traffic, gypsum waste disposal). In order to upgrade the sustainable use of the UNESCO-listed Škocjan Caves for tourism, we propose regular monitoring of PM and a detailed characterization of individual PMs and their sources, in addition to monitoring of the cave’s microclimate and biology. particle identification SEM/EDS source apportionment provenance time series analyses Škocjan Caves true false true Angleški jezik Ni določen Članek v reviji 2024-08-21 12:06:30 2024-08-21 12:06:31 2024-08-22 03:58:11 0000-00-00 00:00:00 2024 0 0 Str. 48313–48331 iss. 35 Vol. 31 2024 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 55 0944-1344 10.1007/s11356-024-34366-8 202313731 s11356-024-34366-8.pdf s11356-024-34366-8.pdf 1 D554F9BBDBD856A45F1672E982D27FDB ba3832a01f63063f73505a29a6bd6f6ff986c0d19ff9e091eeed39c7af78a814 0f741dfe-5fa5-11ef-8f74-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=188606 https://link.springer.com/article/10.1007/s11356-024-34366-8 0 074a1eb3-5fa5-11ef-8f74-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=188605 Naravoslovnotehniška fakulteta 0 0 0
