Texte intégralPer potenza, varietà , quantità e novità dei mezzi utilizzati, la Prima Guerra Mondiale è stata a tutti gli effetti la prima guerra di epoca moderna. Le innovazioni tecnologiche nel settore militare, lo sviluppo degli armamenti e la dimensione "totale" degli scontri tra le nazioni resero questo conflitto molto diverso da quelli dei secoli precedenti. In Italia, la Prima Guerra Mondiale fu combattuta anche in territorio montuoso, glaciale e periglaciale. Il fronte di guerra montano, lungo circa 100 km, si sviluppava sull'arco alpino a quote spesso superiore ai 3000 m sopra le creste di ghiaccio dell'Ortles - Cevedale, sui ghiacciai e sulle montagne del gruppo dell'Adamello-Presanella e della Marmolada. Con il conflitto italo-austriaco nasce quindi la Guerra Bianca, termine che contestualizza la guerra di posizione portata alle quote più elevate, inserita nello scenario globale degli scontri della Prima Guerra Mondiale. Alternativamente creste strategiche, passi e larghe superfici glaciali, furono militarmente occupate dai due eserciti in guerra, difese con medi e grossi calibri, protette da trincee, muniti di ripari in gallerie scavate nella roccia e nei ghiacciai e contese con accanimento dalle truppe di montagna e di fanteria dei due eserciti in lotta. Durante la Guerra Bianca, grandi quantitativi di metalli pesanti (Pb, Cu, Zn, Sb, As, Fe, Sn) sono stati utilizzati per la produzione di esplosivi e munizioni per armi di diverso calibro. Ben nota è la ricaduta ambientale dei metalli pesanti, molti dei quali conosciuti per la loro tossicità, persistenza nell' ambiente, poichè non biodegradabili, e per la tendenza al bioaccumulo e biodisponibilità (Adriano, 2001). Le attività belliche, la persistenza a lungo termine di materiale bellico o la corrosione di frammenti metallici possono, direttamente o indirettamente, rappresentare una fonte di inquinamento da metalli pesanti nelle località alpine interessate dal conflitto andando quindi a incidere su elementi importanti dell'ecosistema globale quale è l'ambiente glaciale. Il progetto di ricerca ha lo scopo di indagare attraverso ricostruzioni storico-geografiche e analisi chimiche il possibile impatto ambientale da metalli pesanti legato al primo conflitto mondiale, combattuto in alcuni siti localizzati sull'ambiente glaciale alpino del gruppo montuoso della Marmolada, dell'Adamello-Presanella e dell'Ortles-Cevedale. Gli obiettivi del lavoro sono stati sviluppati attraverso differenti metodologie di indagine. La rappresentazione cartografica in ambiente GIS, delle aree glacializzate del fronte alpino ha fornito un quadro storico-geografico complessivo della presenza bellica nelle aree indagate e ha portato alla produzione di tre carte tematiche che hanno consentito di localizzare e contestualizzare gli insediamenti militari della Prima Guerra Mondiale sui tre gruppi montuosi interessati dal conflitto. Questa parte del lavoro ha inoltre consentito di definire le aree di influenza di tale presenza, fornendo indicazioni relative ai siti più sfruttati durante il primo conflitto. Il lavoro ha portato inoltre a sviluppare un sistema di gestione delle informazioni in ambiente GIS che, opportunamente implementato e ottimizzato, potrebbe contribuire ad una più efficace archiviazione di documenti cartografici e fotografici relativi alla Prima Guerra Mondiale, attraverso sistemi informativi territoriali. Per valutare gli arricchimenti di metalli pesanti (Pb, Zn, Cu, Sn e Sb) da sorgente bellica nei siti indagati sono state sfruttate le potenzialità combinata di due tecniche analitiche, quali la caratterizzazione chimica multielementare e l'analisi dei rapporti isotopici del Pb, effettuata su diverse matrici ambientali

Texte intégralAmong the multiple stressors that affect aquatic ecosystems, plastic pollution is deemed a widespread and pervasive environmental issue. The majority of the research has been conducted in marine environments and information about the occurrence and effects of these pollutants in freshwater systems is scattered. Moreover, there is a lack of consensus on sampling and analytical procedures for their characterization and quantification, which makes comparison among studies difficult. Besides, more research is needed to assess the influences of plastics and microplastics on ecosystem functions and aquatic organisms, especially focusing on lower trophic levels. Given these gaps, the present project describes four pieces of work that contribute to enhancing our knowledge about plastics and microplastics in freshwater ecosystems. Firstly, since polymer identification constitutes a fundamental step in plastic analysis, the suitability of Raman spectroscopy for polymeric characterization was examined, and a free database with Raman spectra of plastics complemented by a new R package with tools for their processing were developed and described. Advantages and drawbacks of this technique were discussed, with a particular emphasis on plastic additives, which are contained in the majority of polymers but are still poorly investigated, and a catalog with detailed information about peaks of most common plastic polymers was reported to provide guidance for further studies. Secondly, microplastic occurrence in surface water of different freshwater systems was assessed. Indeed, water samples of 38 lakes from 28 different countries covering an assortment of limnologically diverse freshwater ecosystems under varying levels of anthropogenic stress were collected, following a common protocol. This global investigation allowed obtaining comparable data about plastic concentration and features. Moreover, the results suggested the existence of a relationship between urban-related attributes of lakes/watersheds and the plastic concentration but also highlighted as large and deep lakes with high retention times accumulated plastic debris at higher concentrations. Lastly, the relationship between microplastics and microalgae was investigated. This was pursued by combining a critical review of the literature with an experimental approach aimed at analyzing the phytobenthos establishment on two different plastic polymers using a multi-site mesocosm system. This experiment highlighted that microplastics supported the growth of a rich and diversified community of microalgae, showing that many species could coexist on the surface of relatively small plastic items. Species-specificity in the colonization of the different plastic polymers was not observed. Indeed, local species pool and nutrient concentration rather than polymeric composition seemed to be the determinant factors defying the community diversity.

Texte intégralAs a floodplain in which complex human–water systems with dynamic behaviors were established, the Po Plain is considered a key area for the interpretation of long-term relationship between human populations and the environment because of the strategic location between the Mediterranean and continental Europe. This research focuses on the ambitious aim of investigating local and regional environmental changes that occurred in the Po River floodplain as a twofold result of climate changes and human actions during the Holocene. To reach the goal, three terrestrial cores were drilled in the Central Po Plain at different distances from the Terramara S. Rosa di Poviglio, which has been investigated for more than 35 years thanks to the archaeological excavation directed by Maria Bernabò Brea, Mauro Cremaschi and, and in recent years, Andrea Zerboni. All authorizations to carry out the excavation and sampling has been released by the SABAP-BO (MiC) to the Dipartimento di Scienze della Terra “A. Desio” of the Università degli Studi di Milano. The cores were included in the SUCCESSO-TERRA Project (PRIN-20158KBLNB; P.I. M. Cremaschi, A. Zerboni – Università degli Studi di Milano). Concerning the different distances from the archaeological site at which the cores were drilled, it has been decided to name the sequences PVG N-S3 (Near-S3), PVG C-S1 (Central-S1) and PVG F-S2 (Far-S2). Pollen samples were taken throughout the depth of the cores but only the N-S3 core was analysed entirely (77 samples), while palynological analysis of the other cores was carried out for more recent levels according to the focus of the detection of vegetation changes during the Holocene (90 and 28 samples were analysed for the C-S1 and the F-S2 core, respectively). Problems with the reliability of radiocarbon dates influenced by the reservoir effect was attested. Chronology is still in a preliminary stage and will be updated soon with Optically Stimulated Luminescence and possible correlations with other cores in the study area. Four main pollen zones describing events and flora and vegetation transformations were identified according to the cluster analysis and visual examination. Pollen spectra show consistent trends and possible correlations throughout the three cores with a long-term picture of large-scale vegetation changes. At the same time, the collection of the three cores at short distances from each other offers the great opportunity to investigate different features and local variations, among which the main evidence is the decrease in anthropogenic pressure at a greater distance from the settlement. Different statistical elaborations (Principal Component Analysis and Multivariate Curve Resolution-Alternating Least Squares) have provided consistent results which contributed positively to the discussion of the detailed information from pollen data. MCR-ALS has never been applied in Palynology and the results obtained reveal the potential of this method for palynological investigations. The application of statistical methods for quantitative reconstruction of vegetation from pollen data have been deepened at the University of Bergen (Norway). According to the stratigraphy and the possible comparison with the main reference pollen records for the study area, the bottom of the cores could be probably intercepted most of the Lateglacial. Climatic events and the human footprint are certainly reflected in the pollen spectra as part of a single complex dynamic system, from times when climate and ecosystem dynamics were the main factors of vegetation changes to others in which human populations play an increasingly important role with a permanent and extensive impact on the environment up to the current condition.

Texte intégralMultiple stressors affect coastal marine ecosystems, whose effects are often largely unknown. This represents a crucial point, since the knowledge about the impacts caused by human activities are essential to apply adequate monitoring plans and mitigation strategy. Consequently, in this thesis four different human pressures were selected and investigated, in order to increase the available information. The first impact source selected is represented by desalination plants, for which the impact on macrobenthic assemblage was investigated. The results suggest that they do not cause alterations superimposed to the natural spatial variability of the macrofauna assemblage. This has been related to the small sizes of the plants. Similar results were obtained for the second stressor investigated (i.e., beach nourishment and beach re-profiling), which did not alter the spatial-temporal trend of the macro-meiofauna assemblage. Again, the lack of a significant impact was associated to the small size of the interventions. The third case study investigated the long term (40 years) changes (in m2) of seagrass meadow extension in the North Adriatic Sea. The results indicated that the two declines recorded were mainly correlated with two different drivers: urbanization and positive thermal anomalies respectively, which affected not only the meadow extension but also the species composition. Finally, the last pressure analyzed is the fishing with hydraulic dredging, which is extremely intensive in the Adriatic Sea. Specifically, here the effects of the decrease of fishing effort (of about 50%) imposed by the SARS-CoV-2 sanitary emergency was studied. From the results, it is evident a significant increase of bivalves, making the entire macrofauna assemblage significantly different from that present before the 2020. Overall, from these case studies, it is clear as a crucial role is played by the “size” of the human pressure. In addition, it is clear that in different ecosystems, when there is a noticeably decrease of human pressures, an appreciable partial recovery is possible.

Resumo: A caracterização ambiental da microbacia do córrego da fazenda Santa Cândida, manancial periurbano de Campinas (SP), foi realizada a partir da classificação de solos e geoquímica multi-elementar (Ag, AI, As, Sa, Se, Si, Ca, Cd, Ce, Co, Cr, Cs, Cu, Fe, Ga, Ge, Hf, Hg, In, K, La, Li, Mg, Mn, Mo, Na, Nb, Ni, P, Pb, Rb, Sb, Sn, Se, Sr, Ta, Te, Th, Ti, Ta, U, V, W, Y, Zn e Zr) de sedimentos e solos. Amostras superficiais de solo (n = 43) e de sedimentos de corrente (n = 10) foram analisadas por ICPAES, ICPMS ou AAS. Os solos da área, subdivididos em 8 tipos geomorfológicos, foram agrupados estatisticamente em dois grandes domínios geoquímicos, controlados pela natureza da rocha parental: grupo I (solos derivados de diabásios) e grupo 11(solos derivados de granitos e subdivididos em IIa, IIb, IIc e IIe). A geoquímica de sedimentos (fração silte-argila) revelou concentrações anômalas para vários elementos, incluindo Mg, Cr, Sn, Ca, K, Zn, Ag, Mo, Cs, Ni, Rb, Cd, P, Hg e Si, por ordem decrescente de coeficiente de variação nas concentrações. Nos solos, valores anômalos foram computados para K, TI, Sa, Ca, P, Rb, Zn, Cd, Sr, Ag, Pb, Hg, Cu, Ni, Na, Y, Si, Cr, Hf, La e Se, por ordem decrescente de fatores de enriquecimento (entre 13 e 3,1), balizados por amostras de referência da própria área de estudo. As maiores anomalias geoquímicas foram verificadas nos solos dos grupos IIa e IIb, em setores com intensa ocupação residencial e industrial. Uma aparente relação com a ação antrópica também foi identificada na maioria das anomalias em sedimentos. Entretanto, essa relação não pode ser aplicada para todas as anomalias identificadas nos solos, nas quais, e em alguns casos, a contribuição geogênica parece ser mais provável. Apesar das anomalias, apenas em poucos locais os níveis de concentração de Cr, Ni e Zn ultrapassaram valores orientadores para solos do Estado de São Paulo. Valores de referência regional em sedimentos, baseados em poucos estudos anteriores, foram superados pelo Cd, Cr, Cu, Hg, Ni e Zn, com destaque para o Hg que superou em até 16 fatores às áreas comparadas. No caso dos solos, valores máximos de outros estudos da região foram superados pelo Co, Cr, Cu, Mn, Pb, Rb, Ta e Zn, com destaque para o Mncuja concentração foi superior em até 20 fatores
Abstract: The environmental characterization of the fazenda Santa Cândida stream sub-basin, Campinas (SP), was carried out by soil classification and multi-elementary geochemistry (Ag, AI, As, Ba, Be, Bi, Ca, Cd, Ce, Co, Cr, Cs, Cu, Fe, Ga, Ge, Hf, Hg, In, K, La, Li, Mg, Mn, Mo, Na, Nb, Ni, P, Pb, Rb, Sb, Sn, Se, Sr, Ta, Te, Th, Ti, Ta, U,V,W, Y, Zn and Zr). Forty three surface samples of soils and ten surface samples of stream sediments were analyzed by ICPAES, ICPMS or AAS. The soils were subdivided in eight geomorphologic groups, which were classified into two soil geochemistry groups based in their rock affiliation: group I (originated from diabases) and group II (originated from granites), which was subdivided in IIa, IIb, IIc and IId. The sediment geochemistry (silt-clay fraction) revealed anomalous concentration of several elements, which include Mg, Cr, Sn, Ca, K, Zn, Ag, Mo, Cs, Ni, Rb, Cd, P, Hg and Bi, in decreasing order of concentration variability. The anomalous elements in the soils were K, TI, Ba, Ca, P, Rb, Zn, Cd, Sr, Ag, Pb, Hg, Cu, Ni, Na, Y, Bi, Cr, Hf, La and Be, in decreasing order of enrichment factors (between 13 and 3.1), based on local reference standards. The more anomalous concentrations were verified in soils of groups lIa and IIb, within residential and industrial occupation areas. The anthropogenic influences in the anomalous elements concentration was observed in most samples. However, this relation can not be applied for ali anomalies identified in the soils, particularly where the geogenic source appear to be more probable. Nevertheless, locally the concentration levels of Cr, Ni and Zn are high, if compared with oriented values established for São Paulo State. Regional reference values for sediments were exceeded by Cd, Cr Cu, Hg, Niand Zn. Mercury concentration values, for instance, were 16 factors greater. Maximum values from regional studies on soils were exceeded by Co, Cr, Cu, Mn, Pb, Rb, Ta and Zn. Manganese concentration values were 20 factors greater

Texte intégralThe present research aims to define the timing and the extent of the morphological changes occurred in a large gravel bed river, the Piave River in the “Vallone Bellunese” (Eastern Italian Alps) that was heavily impacted by human activities (training structures, hydropower schemes, and gravel mining) and to develop innovative strategies and tools for river management. The Piave River basin (drainage area 3899 km2) lies in the eastern Italian Alps, and the main channel flows south for 220 km from its headwaters (at ~2000 m asl near the Italy–Austria border) to the outlet in the Adriatic Sea NE of Venice. The study rich is 13,5 km long and is located between Soverzene and Belluno in the intermediate course of river within the mountain district. The morphology of the river in the study reach is dominated by braided and wandering channel patterns, but narrower reaches display an alternate bars channel pattern. To achieve the aims of the research the analysis was divided into two phases, in the first phase we collected data about recent and historical morphological evolution (historical maps, aerial photos, topographic surveys and historical photos) and produced thematic maps, in the second phase we produced maps and guidelines useful for river and fluvial corridor management. In the first phase planform changes of river features and bed planform were analyzed on six aerial photos (1960, 1970, 1991, 2000, 2003 and 2006). Aerial photos of 2006, produced by flight specially commissioned by TESAF department, were rectified and coregistered to a common mapping base at 1:5000 by GIS software (Esri ArcGIS 9.1). Significant planform features were digitized on rectified photos in order to derive planform characteristics for each image. Aerial photos of six years analized allowed the identification of these classes: unvegetated active channel, islands with arboreal vegetation, islands with shrubby vegetation, arboreal marginal vegetation, shrubby marginal vegetation, and herbaceous marginal vegetation. Furthermore, three additional classes related to human use of the river corridor were adopted: urban areas, cultivated areas, and gravel mines. The aerial photos of 2006 were also used to distinguish morphological units of the active channel: main channel, secondary channel, lateral low bar, longitudinal low bar, lateral high bar, longitudinal high bar, backwater channel, islands with arboreal vegetation and islands with shrubby vegetation, The objectives of this first phase are to quantify morphological changes in bed planform, to quantify the variation of vegetation cover, with particular emphasis on islands dynamics and to identify the driving factors of channel evolution and vegetation cover changes and thus to envisage the most likely future trends. In the second phase of analysis we produced maps and guidelines useful for river and fluvial corridor management. We analyzed the changes in bed planform due to the occurance of two flood events in 1966 and 2002. The flood event occurred in 1966, with an estimated peak discharge of ~ 3300 m3/s-1 and a RI = ~200 years, is the largest flood event of the twentieth century. The flood event occurred in 2002 with a RI = ~12 years is a more frequent flood event but that had a relevant impact on river morphology. Then we produced a series of maps, starting from the concepts of river corridor and streamway, wich aim to describe and quantify natural processes occurring within the fluvial corridor, such as bank erosion and wood input. The analysis of the historical maps and aerial photographs shows that substantial changes took place in the Piave River within the investigated time interval. The results indicates a marked tendency to the reduction in the active channel, but associated to the main flood events (RI > about 10-15 yr) an increase in the active corridor extensions is apparent. As to the morphological pattern of the entire study reach, this shifted from braided (still dominant until the 1960s) to single thread/wandering in the 1990s. The expansion phase of the last decade is associated with a general recovery of at least a wandering style, with occasional braiding morphology. Reduction of active channel has led a subsequent expansion of the portion of river corridor covered by vegetation. Similarly, the increase in active channel area that took place between 1991 and 2003 occurred mostly at the expense of vegetated areas located at the channel margins. The island dynamics were found to be strictly associated to the occurrence of major floods (RI >10–15 years), which are the only ones able to determine substantial island erosion.
