Texto completoThe accumulation of persistent compounds in biota creates environmental, health and regulatory concerns. Among these substances, the poly-fluorinated compounds (PFASs) represents a case of interest due to their specific physicochemical properties. So the PFAs behavior in the environment is difficult to predict as the existing tools are not suitable. Athough it is recognized that these compounds are persistent and accumulate in biota, many knowledge gaps remain, including the mechanisms of sediment-biota transfer and the factors that control them. This thesis examines the role of sediment in the accumulation process, especially (a) exposure routes of biota, (b) role of biodiversity in the accumulation, by exposing two benthic invertebrates (Chironomus riparius and Gammarus sp.) to natural sediment. The description of PFASs kinetics of accumulation and elimination have showed the biodisponibility of the compounds to organisms. Thus, a bioaccumulation model including the organisms growth and the specificity of the compounds was used to estimate the accumulation and depuration rate constants (ku and ke). A conceptual representation of compounds transfer allowed us to understand the major routes for organisms contamination. Moreover, the interspecific variability has been assessed by comparing the PFASs bioaccumulation and transfer pathways for both invertebrates. This thesis have helped to open up many issues, and especially the influence of both biofilm and organism bioturbation onPFASs bioaccumulation. Moreover some new perspectives on the study of biomagnification were opened

Texto completoThis thesis aims at studying the behaviour of pharmaceuticals in the environment at sediment/soil-water interfaces in order to better understand the involved processes following their release, their fate and their impact. Thus, the retention of four pharmaceuticals was investigated on different solids (soil/sediment). The cation exchange capacity has been identified as the parameter governing the propranolol retention and the pH value governing sotalol adsorption. In the case of contaminant mixtures, a competition for the surface sites was evidenced with in particular a decrease of sotalol and furosemide adsorption.The influence of copper, a ubiquitous metal in the environment, on pharmaceutical retention was also studied. Although copper did not influence the retention of propranolol, sotalol and furosemide, its presence increased the mobility of sulfamethoxazole in the environment by decreasing its adsorption. Finally, it has been shown that the presence of these pollutants in the environment induced toxic effects on aquatic organisms

Texto completoSignificant quantities of radionuclides (mainly radiocesium) were deposited on the soils of Northeastern Japan after the accident of the Fukushima Daiichi Power Plant in March 2011. Starting from late 2013, the Japanese authorities initiated an unprecedented large-scale decontamination programme in cultivated and residential areas affected by the main radioactive plume (8953 km2). The main objective was not to expose local inhabitants to radioactive doses exceeding 1 mSv yr−1 in addition to the natural levels, in order to allow a rapid return of the local inhabitants and the resumption of agricultural activities. In these areas, decontamination consisted of removing the uppermost 5-cm layer of soil that concentrated radiocesium (90-99%) and then replacing it with saprolite sand extracted from local quarries opened for this purpose. Decontamination targeted a minor proportion of the landscape, as farmland covers less than 10% of this region. Furthermore, as agricultural land started to be re-cultivated, many questions were raised regarding the impact of this decontamination work on the transfer of radiocesium into rivers and across landscapes. A multi-proxy sediment tracing approach was designed to quantify the evolution of sources of sediment and particle-bound radiocesium transiting river systems draining the main contamination plume since the accident, through the combined analysis of sediment cores and river flood deposits collected across the region. In 2021, Japanese authorities announced the potential reopening of parts of the Difficult-to-Return zone without obligatory decontamination from Spring 2023 onwards. The current research reconstructed and compared the sources and transfers of sediment and radiocesium in three contrasted catchments (i.e., Mano Dam, Yokokama Dam and Ogaki Dam) where different management modes (and schedules) were implemented. This will shed light into the impact of different management decisions and their timing (early-decontamination or late-decontamination) on sediment and radiocesium transfers in these unique post-accidental conditions

Texto completoIn the framework of Port-Camargue dredge (ECODREDGE-MED project), the main objective was to study the dredged sediment re-sedimentation and matter transfers (particular and molecular matter). An experimental characterization approach was realized in order to study these phenomena working at different scales : macroscopic (sedimentation mechanisms), mesoscopic (particular matter mobilization) and molecular (sorption phenomena). These research works focused on study of five sediments and their granular fractions. A dispersion granular method was developed and highlighted the importance to verify dispersion quality of processes concerning study of granular fractions. Morpho-granular approach used in theses works permitted to highlight cohesive aspect of sediments and to identify different agglomerate types. This approach was also used to propose a classification method of sediments, based on limon/sand ratio determination by laser granulometry.Secondly, re-sedimentation behavior was investigated studying physico-chemical stability of particles in the water column with a suspension analyszer (Turbiscan MA2000). The results contributed knowledge on sedimentation mechanisms and parameter (limon/sand ratio, salinity and volume fraction) influence. With the use of TOC analyze (Total Organic Carbone), matter transfers were identified in water column, via interparticular phenomena (agglomeration/dispersion) and sorption phenomena (adsorption/désorption)

Texto completoSoil erosion is identified as one of the main factors influencing the physico-chemical degradation of the aquatic environments. This phenomenon has been largely described on contrasted topographic areas but there is a gap of knowledge about sediment mobilization/transfer in lowland areas despite the high connectivity level between the potential sources of sediment and the water bodies. In this context we have implemented an integrated multi-parameter approach allowing to track the sediment dynamics in a drained lowland area (the Louroux pond catchment: 47.16°N – 0.78°E) by starting from the sources of sediment to their accumulation in a sedimentary receptacle: the middle-age Louroux pond. The aims of this study are (i) to quantify at long (approx. 60 years) and short time scales (<10 years) the evolution of the erosion rate in the hillslope in link with the increase of the anthropogenic pressures (land consolidation, implementation of the drain network, ditches design), (ii) to track the origin of sediment reaching the pond, (iii) to identify and quantify the parameters influencing bank erosion, that is one of the main source of sediment transfers
