These materials are usually identified and characterized using bulk-scale analytical tools such as X-ray diffraction, Fourier transform infrared spectroscopy or nuclear magnetic resonance. However, there is a need for imaging techniques that provide information on the spatial distribution and chemical composition of the Ca-phosphate phases at the micrometer- and nanometer scales. Such analyses provide insightful indications on how the materials may have formed, e.g. through transient precursor phases that eventually remain spatially separated from the mature phase. Here, we present scanning transmission X-ray microscopy (STXM) analyses of Ca-phosphate reference compounds, showing the feasibility of fingerprinting Ca-phosphate-based materials.

These materials are usually identified and characterized using bulk-scale analytical tools such as X-ray diffraction, Fourier transform infrared spectroscopy or nuclear magnetic resonance. However, there is a need for imaging techniques that provide information on the spatial distribution and chemical composition of the Ca-phosphate phases at the micrometer- and nanometer scales. Such analyses provide insightful indications on how the materials may have formed, e.g. through transient precursor phases that eventually remain spatially separated from the mature phase. Here, we present scanning transmission X-ray microscopy (STXM) analyses of Ca-phosphate reference compounds, showing the feasibility of fingerprinting Ca-phosphate-based materials.

have been recognized as one of the mainly factor which has contributed to the contamination of soils by metals. less attention has been paid to volatile metalloids such as arsenic (as) which accompanies lead (pb) smelting activities. one of the objectives of this study was to determine the as concentrations in various extracting solutions using a collection of urban soils located no far away from two former pb and zinc plants in the north of france. the procedure for the determination of as, asiii, and asv with hydride vapor generator atomic absorption spectrometry was described in

Eventually, we will show on some examples of thermal buildings simulations the necessity to correctly represent the PCM behaviour if one wants to use them in the future so as to save energy and for a better comfort. |

on active foreland-basin margins, where tectonics is likely to strongly impact fluid–rock interactions. a petrographic, geochemical, and microthermometric study of several fractured dolomite concretions and enclosing prodelta marls provides insights into the evolution of burial diagenesis in the eocene sobrarbe deltaic complex (ainsa basin, spain), and more generally, on the paleohydrology of the south pyrenean foreland basin. shallow burial diagenesis was controlled by microbial activity in marine-derived porewaters. microbial sulfate reduction was first responsible for the formation of pyrite and early calcite, followed by the growth of dolomite concretions during methanogenesis. subsequent diagenesis was limited to temperatures and depth of less than approximately 75°c and 2 km, respectively. diagenesis was recorded in porous bioturbation traces and septarian fractures found inside dolomite concretions, as well as in tectonic shear fractures. neomorphic tabular barite, found only in the bioturbation traces, is interpreted to have formed early in marine-derived porewaters. septarian fractures were then filled by fe-rich calcite and centimeter-size celestine. stable isotopes indicate that calcite probably formed in meteoric-derived waters coming from the overlying fluvial delta plain. the sulfur isotope composition of celestine is compatible with precipitation in waters of mixed parentage, but the exact origin of dissolved sulfate remains poorly constrained. in tectonic fractures, celestine precipitated coevally with calcite displaying

focused on the burial diagenesis of deltas deposited on active foreland-basin margins, where tectonics is likely to strongly impact fluid–rock interactions. a petrographic, geochemical, and microthermometric study of several fractured dolomite concretions and enclosing prodelta marls provides insights into the evolution of burial diagenesis in the eocene sobrarbe deltaic complex (ainsa basin, spain), and more generally, on the paleohydrology of the south pyrenean foreland basin. shallow burial diagenesis was controlled by microbial activity in marine-derived porewaters. microbial sulfate reduction was first responsible for the formation of pyrite and early calcite, followed by the growth of dolomite concretions during methanogenesis. subsequent diagenesis was limited to temperatures and depth of less than approximately 75°c and 2 km, respectively. diagenesis was recorded in porous bioturbation traces and septarian fractures found inside dolomite concretions, as well as in tectonic shear fractures. neomorphic tabular barite, found only in the bioturbation traces, is interpreted to have formed early in marine-derived porewaters. septarian fractures were then filled by fe-rich calcite and centimeter-size celestine. stable isotopes indicate that calcite probably formed in meteoric-derived waters coming from the overlying fluvial delta plain. the sulfur isotope composition of celestine is compatible with precipitation in waters of mixed parentage, but the exact origin of dissolved sulfate remains poorly constrained. in tectonic fractures, celestine precipitated coevally with calcite displaying evidence of strong fluid–rock interaction. dissolved sulfate may have migrated to the fractures during active tectonics from the late eocene to the oligocene. the paragenesis and the proposed paleohydrologic model are similar to those previously described for other deltaic systems deposited in active foreland basins, including the south pyrenean foreland basin. these features point to common diagenetic processes in syntectonic foreland-basin deltas, involving both meteoric and marine fluid sources. similar to passive margin settings, early

Lille 1, 318pp, @phdthesis{Leclercq2015, title = {Evaluation de l'efficacité de méthodes d'ingénierie écologique visant à restaurer la fonctionnalité de sols fortement dégradés du Nord de la France}, author = {Julie Leclercq}, year = {2015}, date = {2015-01-01}, school = {Thèse de l’Université de Lille 1, 318pp}, abstract = {De nos jours, les milieux terrestres sont affectés à des degrés divers par les activités humaines. ceci se traduit par une transformation des paysages, une artificialisation des milieux, une fragmentation des unités paysagères, des contaminations organiques et/ou métalliques des sols… la région nord- pas de calais et plus spécifiquement l’ancien bassin minier ne font pas exception. l’ancienne fonderie de plomb metaleurop nord (noyelles-godault) a rejeté des quantités considérables de poussières métalliques dans l’atmosphère qui en retombant sur les sols les ont fortement contaminés en plomb, cadmium et zinc. ceci a engendré de profonds dysfonctionnements comme un ralentissement de la dégradation des matières organiques et perturbent les communautés faunistiques du sol. il a été fait l’hypothèse que la reconnexion des habitats fragmentés, via notamment des plantations arborées, pourrait favoriser la restauration d’une biodiversité fonctionnelle dans les milieux les plus dégradés, tant physiquement que chimiquement. l’objectif principal du travail de thèse a été de proposer et d’évaluer des aménagements en vue de favoriser une reconnexion et une restauration d’une fonctionnalité des sols agricoles les plus contaminés du site atelier metaleurop. ce travail a aussi pour objectif d’améliorer les connaissances sur le fonctionnement et les communautés d’organismes des sols fortement contaminés selon différents aménagements, de favoriser la connectivité écologique entre les éléments paysagers, de prédire l’évolution d’un agrosystème très contaminé dans le cadre d’un projet de phytomanagement et de proposer des préconisations pratiques aux aménageurs pour les parcelles agricoles destinées à être boisées. trois expérimentations ont été menées sur le terrain dans le but de s’intéresser à la fonctionnalité des sols. la première, dresse un état de la fonctionnalité des sols de neuf parcelles anciennement boisées et de trois parcelles de référence (un bois, une haie et un système agricole) à travers la caractérisation et la comparaison d’un panel de 55 indicateurs physico-chimiques et biologiques. les deux autres expérimentations s’intéressent à l’influence d’un aménagement : l’une en étudiant l’influence de la composition pariétale des essences et la pollution métallique des litières, l’autre tournée davantage sur le processus de dégradation d’une litière de feuilles de peuplier non contaminée et réalisée au moyen de la technique des sacs de litière. l’étude de la recolonisation des milieux dégradés, à l’aide d’une technique d’aménagement paysager simple, le mulching, a été réalisée avec la mise en place d’une expérimentation sur le terrain destinée à évaluer des mulchs de différentes natures et ceci durant deux années. les principales conclusions de ce travail en termes de préconisations sont de favoriser les plantations mixtes et les essences locales, prendre en compte les types de sol (teneurs en caco3 total, degré d’hydromorphie, concentrations en métaux…) et les exigences écologiques des essences envisagées, amender les sols avec des amendements minéraux ou organo-minéraux afin de limiter la mobilité des métaux, varier les densités de plantation afin de favoriser un maximum

terrestres sont affectés à des degrés divers par les activités humaines. ceci se traduit par une transformation des paysages, une artificialisation des milieux, une fragmentation des unités paysagères, des contaminations organiques et/ou métalliques des sols… la région nord- pas de calais et plus spécifiquement l’ancien bassin minier ne font pas exception. l’ancienne fonderie de plomb metaleurop nord (noyelles-godault) a rejeté des quantités considérables de poussières métalliques dans l’atmosphère qui en retombant sur les sols les ont fortement contaminés en plomb, cadmium et zinc. ceci a engendré de profonds dysfonctionnements comme un ralentissement de la dégradation des matières organiques et perturbent les communautés faunistiques du sol. il a été fait l’hypothèse que la reconnexion des habitats fragmentés, via notamment des plantations arborées, pourrait favoriser la restauration d’une biodiversité fonctionnelle dans les milieux les plus dégradés, tant physiquement que chimiquement. l’objectif principal du travail de thèse a été de proposer et d’évaluer des aménagements en vue de favoriser une reconnexion et une restauration d’une fonctionnalité des sols agricoles les plus contaminés du site atelier metaleurop. ce travail a aussi pour objectif d’améliorer les connaissances sur le fonctionnement et les communautés d’organismes des sols fortement contaminés selon différents aménagements, de favoriser la connectivité écologique entre les éléments paysagers, de prédire l’évolution d’un agrosystème très contaminé dans le cadre d’un projet de phytomanagement et de proposer des préconisations pratiques aux aménageurs pour les parcelles agricoles destinées à être boisées. trois expérimentations ont été menées sur le terrain dans le but de s’intéresser à la fonctionnalité des sols. la première, dresse un état de la fonctionnalité des sols de neuf parcelles anciennement boisées et de trois parcelles de référence (un bois, une haie et un système agricole) à travers la caractérisation et la comparaison d’un panel de 55 indicateurs physico-chimiques et biologiques. les deux autres expérimentations s’intéressent à l’influence d’un aménagement : l’une en étudiant l’influence de la composition pariétale des essences et la pollution métallique des litières, l’autre tournée davantage sur le processus de dégradation d’une litière de feuilles de peuplier non contaminée et réalisée au moyen de la technique des sacs de litière. l’étude de la recolonisation des milieux dégradés, à l’aide d’une technique d’aménagement paysager simple, le mulching, a été réalisée avec la mise en place d’une expérimentation sur le terrain destinée à évaluer des mulchs de différentes natures et ceci durant deux années. les principales conclusions de ce travail en termes de préconisations sont de favoriser les plantations mixtes et les essences locales, prendre en compte les types de sol (teneurs en caco3 total, degré d’hydromorphie, concentrations en métaux…) et les exigences écologiques des essences envisagées, amender les sols avec des amendements minéraux ou organo-minéraux afin de limiter la mobilité des métaux, varier les densités de plantation afin de favoriser un maximum d’espèces, développer des zones de transition entre les milieux et accélérer le processus de colonisation via la technique du mulching. il serait intéressant de mettre en place de nouvelles plantations mixtes, trop rares sur le secteur et tester différents assemblages avec des densités de plantations variables et différents amendements. de nouvelles études pourraient confirmer les choix des essences et préciser la viabilité écologique des modes de gestion mis en place. l’utilisation de mulchs au pied des jeunes haies / plantations devrait permettre d’accélérer la colonisation de ces nouveaux milieux et pourrait contribuer à renaturer les espaces les plus dégradés |

chemical analyses have to be taken into account to monitor anthropic contamination of soils. biological responses of exposed organisms should be considered too and particularly for environmental genotoxicants as pahs or metals. it is well-known that studies of soil contaminations are complex. for example, the environmental availability, environmental and toxicological bioavailabilities of present metal contaminants, influenced by soil factors, ageing phenomena, organic matter..., their concomitant presences, and often at low concentrations and then their potential toxic interactions have to be considered. that’s why methods of classical genetic toxicology (indirect testing, unrealistic exposure...) did not seem fully satisfactory. several years ago, we developed an environmental genotoxicity marker with eisenia fetida,the comet assay. it is a technique allowing the evaluation of dna damage (single and double strand breaks, alkali-labile sites) in a cellular population and it was developed on cœlomocytes of this biological model largely used in soil ecotoxicology. in this poster presentation, we will present obtained results in different contexts with this environmental genotoxicty marker: exposures to field-contaminated soils (1), to spiked soils with a mixture of metals (2) and to soils after a remediation treatment (3). in the first work (1), in vivo short-term exposures of e. fetida were conducted using soils sampled in two different areas in the north of france: from the vicinity of a former smelter and from a suburb zone close to a battery plant still in

have to be taken into account to monitor anthropic contamination of soils. biological responses of exposed organisms should be considered too and particularly for environmental genotoxicants as pahs or metals. it is well-known that studies of soil contaminations are complex. for example, the environmental availability, environmental and toxicological bioavailabilities of present metal contaminants, influenced by soil factors, ageing phenomena, organic matter..., their concomitant presences, and often at low concentrations and then their potential toxic interactions have to be considered. that’s why methods of classical genetic toxicology (indirect testing, unrealistic exposure...) did not seem fully satisfactory. several years ago, we developed an environmental genotoxicity marker with eisenia fetida,the comet assay. it is a technique allowing the evaluation of dna damage (single and double strand breaks, alkali-labile sites) in a cellular population and it was developed on cœlomocytes of this biological model largely used in soil ecotoxicology. in this poster presentation, we will present obtained results in different contexts with this environmental genotoxicty marker: exposures to field-contaminated soils (1), to spiked soils with a mixture of metals (2) and to soils after a remediation treatment (3). in the first work (1), in vivo short-term exposures of e. fetida were conducted using soils sampled in two different areas in the north of france: from the vicinity of a former smelter and from a suburb zone close to a battery plant still in activity. in the second (2), in order to better understand metal interactions, in vivo short to mid-term exposures (3, 10 and 56 days) were performed using an urban-surrounding soil spiked with cadmium or/and lead at concentrations found in french contaminated soils. in the last work (3), in vivo short-term exposures of e. fetida were conducted using a contaminated soil sampled in the field and a reference soil contaminated or not by a mixture of lead, zinc and cadmium. in both soils were added (or not) remediation agents (biochars from two origins) at two concentrations. in all cases,
