Since 30 years ago, the growing use of Lanthanides in new technologies has contributed to important releases of these metals into aquatic ecosystems. In a global sustainable development policy aimed at preserving the quality of ecosystems, the impact of Lanthanides on aquatic organisms has naturally been questioned. However, studies on the aquatic ecotoxicology of Lanthanides are incomplete, and no consensus is established yet. In this context, we studied the cellular toxicity of Lanthanides individually and in mixtures. To determine these toxic effects, cell viability was measured on Danio rerio fibroblast-like cells (ZF4; ATCC®, CRL-2050™), Danio rerio hepatic cells (ZFL; ATCC®, CRL-2643™), Oncorhynchus mykiss epithelial cells (RTgill-W1; ATCC®, CRL-2523™), and primary culture of Corbicula fluminea digestive glands exposed to Lanthanides. Direct toxicity of Lanthanides has been observed on all cellular models. Concerning the toxicity of Lanthanides in mixtures, synergistic effects have been underlined on the three fish cell lines. In this research, we focused on the mechanisms of the detoxification of Lanthanides in the case of ZF4 cells from Danio rerio. The effects of Lanthanides were assessed in the presence of specific inhibitors of glutathione-S-transferases (ethacrynic acid) and MRP-like (MK571 and probenecid), by cell viability measurements. We decided to study these actors of the cellular detoxification due to their respective roles in phases II and III of the cellular detoxification of metals in fishes and bivalves. Regarding the results, MRP-like proteins are effectively involved in the detoxification of Lanthanides in ZF4 cells. Overall, our results highlighted the relevance of the toxic effects of Lanthanides at the cellular level for the risk assessment of these metals

This PhD was focused on the development of the use of rare earths in catalysis and in particular for aminolysis of functionalized meso epoxides and aziridines by aromatic amines. The samarium diiodide is used as a catalyst of Lewis acid type and we have shown that samarium diiodide catalyzes the aminolysis of functionalized epoxides in mild conditions and allowes to isolate various new aminoalcohols despite the presence of an additional heteroatom. Samarium iodo binaphtholate is an efficient catalyst for asymmetric ring opening of epoxides containing different heteroatoms by aromatic amines such as aniline, ortho- or para-anisidine. Many β-aminoalcohols containing heterocycle, not described in the literature before our study, have been isolated with enantiomeric excesses up to 71%. These catalysts were also tested in the aminolysis of activated or no activated aziridines reaction. Various 1,2-diamines have been isolated under mild conditions but with samarium iodo binaphtholate diamines were isolated with low ee in all cases. In order to increase enantiomeric excesses, we have described a synthesis for new complexes of rare earths prepared by a very simple procedure from rare earth chloride, lithium trimethylsilyl and binaphthol. These new complexes are heterobimetallic compounds and complexes of samarium, yttrium, neodymium, scandium and lanthanum were successfully isolated. The complexes of samarium and yttrium catalyzed under mild conditions the aminolysis reaction of functionalized epoxyde. The β-aminoalcohols were prepared with enantiomeric excesses up to 84% in the case of the reaction between the epoxide of 2,5-dihydrofuran and para-anisidine

Highly organized polymetallic architecture creation is crucial for development of new molecular materials that employing magnetic, optical and catalytic properties of lanthanides. Our work consisted in preparing, by a control of rare earth ion hydrolysis, polynuclear lanthanide complexes. The two first are devoted respectively to a bibliographical review of the various polynuclear rare earth systems synthesized to this day ; with the chemical ans physical properties of the lanthanide ions. The following chapters relate to the experimental parts of this work. The synthesis route is based on a hydrolysis control of lanthanide ions in solution. According to the hydrolysis rate, we obtained either non-hydroxylated coumpounds containing lanthanide ions, or rare earth hydroxysels, or finally of lanthanide hexanuclears under controlled hydrolysis conditions. The last part of this work is devoted to utilization of lanthanide hexanuclears like new molecular precursors

Control of urban pollutants is a major issue, especially in coastal areas, in a context of rapidly growing urbanization and the emission of emerging potentially highly toxic contaminants, such as Rare Earth Elements (REEs). This study is a part of the REGARD project and aims at understanding the dynamics of “conventional” trace metals (Tms) and REEs in the Jalle River, the main urban hydrosystem draining the Bordeaux Metropole and to assess its influence on the Garonne section of the Gironde estuary after having characterized two major urban sources: domestic wastewater and stormwater runoff draining the Bordeaux Highway. Due to its use as a contrast agent for MRIs and its low removal in WWTPs, gadolinium (Gd) is an excellent tracer of the domestic/hospital urban source in the Jalle River. With an annual flux estimated at 27 kg.yr-1 (23 mg.hab-1.yr-1) of dissolved Gdantrh in the Garonne River, the Bordeaux Metropole contributes nearly 25% of the Gd in the main branch of the Gironde Estuary. This flux have probably evolved like those of the Garonne at its outlet (before Bordeaux Metropole) which have doubled over the past two decades (2003: 32 kg.yr-1; 2017: 75 kg.yr-1) due to the increase in MRIs on the Garonne watershed. The high temporal analysis of a major summer rainstorm showed that the relative contributions of the daily TM fluxes of the Jalle River ranged from: 5 %(Sr) - 40%(Cu) for dissolved phases and 30% (As) – 88% (Cu) for particulate phases. The first forty minutes of the event (<17% of time) accounted for 65% of the SPM flux (and associated particulate TMs) exported by the stormwater runoff because of the first-flush of road dust. If Cu and Zn fluxes had significant contribution for the Jalle River, they are not good tracers of traffic-related source because of their ubiquitous uses. Although cerium anomalies are still weak, it should be a future good tracer with higher traffic density and technological development in catalytic converters. Using a 2-year monitoring along the Jalle continuum, this study demonstrated the upstream watershed strongly influences the geochemical composition of the Jalle River for many majors and TMs (e.g. Al, Fe, REEs) and that it contributes the bulk of dissolved TM fluxes (Al: 96%; REEs: 96 - 99%). The domestic source, via the WWTP loads, continuously affects the quality of the Jalle waters by significantly increasing dissolved Ni, Sn, Cu, Ag and Gd concentrations, mainly during low water conditions due to lower dilution by the upstream Jalle River. Conversely, the traffic-related (highway) source influences the Jalle River only more intermittently with regard to dissolved and particulate Cu, Zn, Sb during major summer rainstorm. Finally, further works on geochemical cycles of TMs at the urban-estuarine interfaces will be essential to reduce dispersion of TMs in urban systems, in order to limit impacts on natural environmental systems and to develop methods for the recovery and recycling of technology-critical elements
