Full textMarine sediments concentrate various pollutants and subsequent sedimentation of harbors and ports require periodic dredging to maintain satisfactory depth of waterways. Direct land deposition of contaminated marine dredged sediments pose risk to the environment due to possible leaching of trace elements. In this context, we aimed to study the feasibility of trace elements stabilization by mixing 5% and 20% of bauxite residues (bauxaline®, bauxsol and neutralized bauxaline®) with composted dredged marine sediment. The treatment efficiency was evaluated by monitoring the leached trace elements concentration and toxicity of sediment leachates. 20% amendment application successfully stabilized cationic pollutants (Cu, Cd, Zn) up to 40-80%, and decreased the toxicity of sediment leachates. Whereas, anionic pollutants (As, Mo) were less immobilized require further investigation

Full textAntropic activities lead to the metallic contamination of river sediments. Most of trace metals are sorbed on sediments but a part of them can be released into aquatic environment when environmental conditions are modified. This is often due by the autochthonous microbial activity. Microbial activites and their consequences on the mobility of metals have been widely studied in soils. Metals are released through direct or indirect microbial mechanisms. Such studies in the case of sediments are very seldom. However, it can be usefull to understand the microbial mechanisms of metal release in sediments, and particularly for a good management of dredged sediments. In this environmental framework, the aim of this research work was to understand and to evaluate the role of the microbial and chemical mechanisms in the release of metals from river sediments in anaerobic conditions. Firstly, sediments from the Marne and Seine rivers were incubated in anaerobic conditions. A high solubilisation of iron and manganese occurred associated to the solubilisation of trace metals (Co, Cu, Ni, Pb). Meanwhile, organic acids were produced and the medium was acidified. Thus fermentation was supposed to be the main process of microbial metabolism. Furthermore these observations led us to suppose the presence of iron-reducing bacteria. In a second step, the extent of the iron-reducing activity was studied. The main iron-reducing bacteria identified in the Marne sediments belonged to the species Clostridium butyricum and Paenibacillus polymyxa. The use of a geochemical model revealed that fermentation and reduction of iron(III) were the main metabolic pathways. Finally direct (enzymatic reduction) and indirect (complexation with organic acids, acidification) impacts of iron-reducing bacteria on the release of metals were compared. Acidification and organic acids had a weak impact on metal solubility in the range of studied pH (between 6,5 and 5). Enzymatic reduction is the main mechanisms of metal release in anaerobic conditions. Indeed the metallic concentrations can be 40 times higher in the presence of iron-reducing bacteria

Full textOver the last decade, we have seen a rise in popularity of mobile applications based on phone location. These applications collect mobility tracks which describe the movement of users overtime. In the DA3T regional project, we hypothesise that the analysis of tourists’ mobility tracks can help planners in the management and enhancement of tourist areas. The objective is to design methods and tools to help analyse these tracks. This thesis focuses on the processing of mobility tracks and proposes a modular platform for creating and executing processing chains on these data. Throughout the modules of a processing chain, the raw mobility track evolves into semantic trajectories. The contributions of this thesis are: (i) a multi-level and multi-aspect semantic trajectory model and (ii) two measures that compute the similarity between two semantic trajectories along spatial, temporal and thematic dimensions. Our model (i) is used as a transition model between modules of a processing chain. We tested it by instantiating semantic trajectories from different datasets of various domains. Our two measures (ii) are integrated in our platform as processing modules. These measures present originalities: one is the combination of sub-measures, each allowing to evaluate the similarity of trajectories on the three dimensions and according to three different levels of granularity, the other is the combination of two bidimensional sub-measures centred around a particular dimension. We evaluated our two measures by comparing them to other measures and to the opinion of geographers

Full textThis Ph.D. thesis tackles the places and circulations involved in the making of art in a southern metropolis. It is situated at the crossroads of an urban geography concerned with the social and spatial layout through which this “ordinary” activity is organized, and a geographical approach of art that places actors’ trajectories at the heart of the analysis. Capital city in a postcolonial State, East African metropolis and periphery of the “global archipelagic economy”, Nairobi is a case of the encounter between metropolization and globalization. In the trail of the theories on the worlding of material geography, this study aims at documenting and mapping the reconfigurations of art space triggered by these dynamics. The novelty of this thesis is to assemble the entire range of art scenes and products of a city, using the common thread that is the spatial dimension of their circulations. The material studied (artists’ discourse and curriculum vitae; art centres activity and archive) takes on both the measureable circulations of artists while confronting them to their horizon of accomplishment. These are made up of the persistence of strong rural ties and the connectivity of a globally connected city. The method deployed relies on the notion of traceability and is based on a qualitative survey through observation. An exhibition, a performance, a mobility grant, a visiting curator, collector or benefactor, the daily circulations and socializing of an artist: all these individual, material, ideal or financial movements constitute the raw material of this research. The notion of art mobility is here understood as the articulation between artists’ agency and spatial tactics on the on hand, and the material and institutional means of dealing with distance on the other hand. Art mobility questions the conditions, directions and meanings of these movements as much as the growth of the actors engaged

Full textThis study deals with the assessment of sediment contamination levels by trace metals in the Toulon bay, a semi-closed Mediterranean area submitted to heavy anthropogenic inputs. The sampling of interface cores in 52 points located in thewhole bay allowed establishing a precise mapping of the sedimentary characteristics and the metals/metalloids contents. The obtained results from the surface sediments revealed a significant contamination of the bay (especially for Cu, Hg, Pb and Zn), mainly in the most enclosed parts of the small bay. There, the levels may exceed by several orders of magnitude the limits concerning dredging operations defined by the French legislation. The observed contamination distribution clearly indicated an export from the small to the large bay (normally less exposed) probably governed by hydrodynamic processes, responsible for the contaminated sediment resuspension. The sedimentary profiles of interface cores sampled in contrasted contamination areas revealed the presence of systematic contamination peaks in the first 20 cm. Taking into account the calculated sedimentation rate, this would demonstrate that the Toulon bay was submitted to a strong multi-contamination, probably linked to the 2nd world war. The analysis of interstitial waters (physico-chemical parameters,major, trace metals, and diagenetic tracers) allowed studying trace metals mobility. The obtained profiles appeared mainly controlled by diagenetic mechanisms and showed the major role of the main carrier phases present in the sediments (oxyhydroxides of Fe and Mn, sulphides). The modeling of these profiles led to the determination of the diffusive fluxes at the sediment/water interface, and so, to the action of the sediment as a sink or a source of contamination for the water column.The calculated outgoing diffusive fluxes appeared relatively low in comparison to the total contents measured in the sediment, proving that the main part of the studied trace metals remains in the sediment. Finally, resuspension experiments in lab and on field were performed with the aim to simulate different possible scenarios (storm,nautical traffic, dredging). Under the studied conditions, the remobilization can be low for some trace metals (e.g. As, Hg), but it may contrariwise be quite important for others (e.g. Cd, Cu, Pb) leading to a non-negligible contamination of the water column

Full textTo determine the impact and risk of chemical fertilizers, from their manufacture to their amendment, on soil contamination by trace metals, the study of their mobility and transfer would be necessary. The objective of this work was to evaluate the source of soil contamination by trace elements around the industry of chemical fertilizers, and to follow the temporal evolution of mobility and transfer of these elements in the profile of agricultural soil amended by superphosphate (SSP) fertilizers or phosphogypsum. To achieve our objective, we used techniques allowing the determination of structural and mineralogical characterization of collected soil samples, such as X-ray diffraction and electron microscopy. Chemical characterization related to the total concentration of trace and major elements of collected soils was established. As mobility was unstable over time, depending on several physico-chemical parameters such as pH, redox potential, and organic matter content, a sequential extraction was adopted throughout the study over time in the amended soil profile to a depth of 55 cm. In addition, the absorption of trace elements by agricultural crops cultivated over land amended with fertilizer or phosphogypsum was analyzed over time to assess the risk of their transfer to the food chain, especially the human food chain, imposing health hazards. A comparison between the effects of the application of phosphogypsum and phosphate fertilizer was carried out in concluding this work

Full textThis thesis dealt with the determination and study of the ecodynamics of trace metals in technosols highly contaminated in metals and metalloids in the context of natural revegetalisation or phytoremediation. Two sequential extraction schemes were used jointly with selective extractions in parallel with the determination of the total metals concentration in soils, the total dissolved metals concentration in the soil pore water, the metals labile pool (DGT) and germination tests with dwarf beans to investigate the speciation, mobility and phytoavailability of (Zn, Pb, Cd, As and Sb) for technosols of two post-mining (La Petite Faye) and industrial (Mortagne du Nord) sites. Additionally, young plants of P. euramericana Dorskamp were cultivated in rhizobox on Mortagne du Nord technosols to investigate the rhizospheric effect on the mobility of metals. Moreover, the effect of nitrogen addition under nitrate and ammonium on the behavior of these metals has been investigated for P. euramericana Dorskamp for the same soils. Despite the high total metals and metalloids concentration in the La Petite Faye soils, the mobility of these potentially toxic elements is limited because of their association with the residual fraction. The phytoavailability is also limited and correlated with the labile pool of technosols. The culture of P. euramericana Dorskamp generated a rhizospheric effect characterized by an increase of the pH and concentration of dissolved organic carbon (DOC) in the soil pore water and a decrease in the total dissolved concentration of metals (Zn, Pb et Cd) in the soil pore water. The addition of nitrogen under nitrate or ammonium respectively increased and decreased the soil pore water pH and in the case of ammonium the DOC also increased and stabilized metals in the rhizosphere in comparison to control soils
