“…Vulcano is an inhabited island with resident citizen and in summer is a destination for many tourists. Its active cone (La Fossa) erupted for the last time in 1888–1890 [ 1 ]. After this eruption, the volcano emitted, from the La Fossa crater, only fumaroles composed of water and acid gases (SO 2 , H 2 S, HCl, HF), traces of gaseous elements (He, Ne) and metallic trace elements [ 2 – 4 ].…”

The impact of volcanic airborne products on airway epithelium homeostasis is largely unknown. This study assessed the effects of volcanic Fumarole Condensates (FC) alone or combined with Cigarette Smoke Extracts (CSE) on airway epithelial cells (16HBE and A549). Chemical composition of FC was analyzed by gas chromatography and HPLC. Cells were exposed to FC and IL-33 and IL-8 were assessed. The effects of FC and CSE on cell injury were evaluated assessing cell metabolism/cell viability, mitochondrial stress, cell apoptosis/cell necrosis, and cell proliferation. FC contained: water vapor (70–97%), CO2 (3–30%), acid gases (H2S, SO2, HCl, HF) around 1%. FC increased the intracellular IL-33 but differently modulated IL-33 and IL-8 gene expression and IL-8 release in the tested cell lines. FC without/with CSE: (a) increased cell metabolism/cell viability in 16HBE, while decreased it in A549; (b) increased mitochondrial stress in both cell types. FC with CSE increased cell necrosis in A549 in comparison to CSE alone. CSE reduced cell proliferation in 16HB,E while increased it in A549 and FC counteracted these effects in both cell types. Overall, FC induce a pro-inflammatory profile associated to a metabolic reprogramming without a relevant toxicity also in presence of CSE in airway epithelial cells.

The intense explosive and effusive volcanic activity of the last 1000 years at La Fossa volcano (Vulcano Island, Italy) 13 was characterized by the eruption of magmas ranging in composition from latites to trachytes and rhyolites, as well as K-14 rich trachytes. Evidence of sin-eruptive mixing among these magmas are frequently observed in the form of magmatic 15 enclaves and bands in lava flows and pyroclastic products. The petrological and volcanological diversity of the erupted 16 materials suggests that complex differentiation processes occurred in the shallow part of the plumbing system. With the 17 aim to reconstruct the magmatic feeding system and to identify the differentiation processes behind such a petrologic 18 complexity, we analyzed lavas and pyroclastic products representative of the recent eruptive sequences at La Fossa and 19 combined the petro-chemical features with thermo-barometric calculations, geochemical modelling and temperature 20 gradient experiments. Thermo-barometric calculations indicate that the K-rich trachytic magma crystallized at lower 21 pressure (16054 MPa) compared to the latitic (30747 MPa) and trachytic (20830 MPa) magmas. Differentiation 22 modelling suggests that both trachytic and rhyolitic compositions can be obtained through differentiation of a common 23 latitic magma, essentially by varying the plagioclase/sanidine ratio. Temperature gradient experiments, performed at the 24 conditions inferred for the shallow plumbing system of La Fossa volcano (150 MPa and 1050-900 °C), indicate different 25 paths of melt differentiation that overall produce an increase of the SiO2/K2O ratio with the increasing H2O in the system 26(from 0 to 4 wt.%). This is consistent with the origin of K-rich trachytes at lower pressure and lower H2O content. In turn, 27 the formation of crystal-poor rhyolites is explained by segregation of the interstitial melt formed in a latitic-trachytic 28 crystal mush, favored by the second boiling of the melt and consequent exsolution of a fluid phase.
