    TRACE ELEMENTS IN HIGH INCIDENCE AREAS OF MULTIPLE SCLEROSIS: A ROLE OF VOLCANOGENIC ASHES? (2023)
    Springer Nature
    Details
    Publikationsdatum: 2023-02-07
    Beschreibung: Objective: To study the blood levels of selected trace elements (TE) in Multiple Sclerosis (MS) patients living in high-incidence cluster areas in the Etna volcano region. Methods: MS patients living in the province of Catania have been retrospectively enrolled among those followed by the Neurologic Clinic of the AOU Policlinico “G. Rodolico-San Marco” who had the disease onset between 2005 and 2020.Aserumsample was used for the determination of TE levels (As,Cd, Cr, Cu, Fe, Mg, Mn, Ni, Se, Zn). All the analyses have been conducted with an ICPMS with the standard addition technique, previous digestion of the samples with nitric acid. MS patients living the high incidence clusters were frequency matched with MS patients living outside the clusters. Comparisons of TE across the groups were conducted using the Mann-Whitney test. Results: A total of 86 (48 women; 55.8%) MS patients was recruited, with a mean age of 41.6±13.1 years, a mean disease duration of 2.0±2.6 years and a mean Expanded Disability Status Scale of 2.3±1.7. Of these patients, 40 belonged to high incidence clusters and 46 were outside the clusters. No differences were found in demographic characteristics between the groups. Concerning TE, we found a significant higher concentration of Mn in incluster patients (6.7±16.6 μg/L vs 2.5±5.9 μg/L). Discussion: Several environmental factors may modulate the pathogenesis of the disease, and among them TE play an important role. Our findings suggest that Manganese, which has several toxic effects, might contribute to the higher incidence of MS previously observed in a cluster of communalities in the south-eastern flank of the Etna volcano, where volcanic ashes rich in TE usually fall due to the prevailing winds. Conclusions: Exposition to high levels of Mn could be a cofactor in the pathogenesis of MS.

    Energy threshold changes in volcanic activity at Mt. Etna (Italy) inferred from volcanic tremor (2022)
    Springer Nature
    Details
    Publikationsdatum: 2022-10-28
    Beschreibung: From the 2010s on, pattern classification has proven an effective method for flagging alerts of volcano unrest before eruptive activity at Mt. Etna, Italy. The analysis has been applied online to volcanic tremor data, and has supported the surveillance activity of the volcano that provides timely information to Civil Protection and other authorities. However, after declaring an alert, no one knows how long the volcano unrest will last and if a climactic eruptive activity will actually begin. These are critical aspects when considering the effects of a prolonged state of alert. An example of longstanding unrest is related to the Christmas Eve eruption in 2018, which was heralded by several months of almost continuous Strombolian activity. Here, we discuss the usage of thresholds to detect conditions leading to paroxysmal activity, and the challenges associated with defining such thresholds, leveraging a dataset of 52 episodes of lava fountains occurring in 2021. We were able to identify conservative settings regarding the thresholds, allowing for an early warning of impending paroxysm in almost all cases (circa 85% for the first 4 months in 2021, and over 90% for the whole year). The chosen thresholds also proved useful to predict that a paroxysmal activity was about to end. Such information provides reliable numbers for volcanologists for their assessments, based on visual information, which may not be available in bad weather or cloudy conditions.

    Applying the Values of Geoethics for Sustainable Speleotourism Development (2020)
    Springer Nature
    Details
    Publikationsdatum: 2020-09-01
    Beschreibung: Establishing sustainable and responsible speleotourism development is a major challenge and involves complex activities. Adequate theoretical starting point is the application of geoethical values related to the conservation and protection of the caves to be used for touristic purposes. Positive and negative cases of human behaviors towards speleological geoheritage are discussed, in order to highlight what should be done in cave management to avoid malpractices and on what elements could be founded adequate strategies aimed at promoting sustainable speleotourism. This is important to tourism management organizations involved in the promotion of caves and in creating economic opportunities for local populations, while respecting cave ecosystems. Modern cave management must be focused on the protection of the cave ecosystems, finding ways to achieve at the same time an economic development of local communities. But this approach needs the adoption of a geoethical framework of values to be shared by all stakeholders involved so that successful cooperation can be achieved despite differences in interests and expectations. The aim of this paper is to raise the awareness about the need to apply the values of geoethics to speleotourism, stimulating new fields of discussion within the scientific and technical communities involved in studies and activities related to geotourism and geoheritage. The possibilities of developing new ways to manage caves, in order to promote a sustainable socio-economic development of local communities, have to be balanced with the protection of natural environments as much as possible. The proposed theoretical frameworks have the goal to increase the discussion on the best ways of connecting speleotourism to sustainable and responsible cave management, presenting two case studies, and pointing out potential solutions.
