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 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},

abstract = {Chemical speciation of metals in soil/solution plays an important role in determining their biogeochemical behavior in soil-plant system. the current study evaluated the influence of applied form of pb (metal speciation) on its toxicity to metal sensitive vicia faba l. roots. lead was applied to young v. faba seedlings alone or chelated by organic ligands (citric acid and ethylenediaminetetraacetic acid). plants were exposed to all treatments for 1, 4, 8, 12, and 24 h in nutrient solution, and contents of h2o2 and thiobarbituric-acid-reactive substances (tbars) production were analyzed in v. faba roots. the results showed that pb toxicity to v. faba roots depended on its applied chemical form and duration of exposure. lead alone caused two burst of lipid peroxidation and h2o2 induction at 1 h and 12 h. addition of edta dose-dependently inhibited pb-induced h2o2 and tbars production, indicating a protective role of this chelator against pb toxicity during the first 24 h. in contrast, citric acid did not show significant effects on pb-induced h2o2 and tbars production, but delayed the induction of these effects. this study suggested that pb toxicity to v. faba roots varies with pb speciation in growth medium.},

	is a well-known genotoxic and mechanisms explaining its clastogenicity 

	are mainly indirect: inhibition of DNA repair mechanisms and/or induction 

	of Reactive Oxygen Species (ROS). Animal or vegetal cells use antioxidant 

	defense systems to protect themselves against ROS produced during 

	oxidative stress. Because tolerance of organisms depends, at least 

	partially, on their ability to cope with ROS, the mechanisms of production 

	and management of ROS were investigated a lot in Ecotoxicology as 

	markers of biotic and abiotic stress. This was mainly done through 

	the measurement of enzyme activities The present Review focuses on 

	3 test species living in close contact with soil that are often used 

	in soil ecotoxicology: the worm Eisenia fetida, and two plant species, 

	Trifolium repens (white clover) and Brassica oleracea (cabbage). 

	E. fetida is a soil-dwelling organism commonly used for biomonitoring. 

	T. repens is a symbiotic plant species which forms root nodule with 

	soil bacteria, while B. oleracea is a non-symbiotic plant. In literature, 

	some oxidative stress enzyme activities have already been measured 

	in those species but such analyses do not allow distinction between 

	individual enzyme involvements in oxidative stress. Gene expression 

	studies would allow this distinction at the transcriptomic level. 

 

	A literature review and a data search in molecular database were carried 

	out on the basis of keywords in Scopus, in PubMed and in Genbank™ 

	for each species. Molecular data regarding E. fetida were already 

	available in databases, but a lack of data regarding oxidative stress 

	related genes was observed for T. repens and B. oleracea. By exploiting 

	the conservation observed between species and using molecular biology

	the measurement of most genes involved and/or related to antioxidant

abstract = {Through their activities, humans contaminate their environment, by discharging intentionally or not organic or inorganic pollutants. the latter cause adverse effects on the ecosystems and this pollution contribute to the major causes of the global decline of biodiversity, including amphibians. indeed, the aquatic compartments are particularly affected by anthropogenic contaminations. the aim of this work was to highlight the effect of metallic environmental exposure on xenopus laevis oocytes. cadmium (cdcl2), an inorganic compound with natural and mainly anthropogenic sources, such as metallurgy, was chosen. we first focused on cell survival with phenotypical (morphology, pigmentation), physiological (maturation ability) and electrophysiological (resting potential) approaches. then, maturation was assessed in vitro, with morphological (migration and breakdown of the germinal vesicle – gvbd), biochemical (activation of mapk – mitogen activated protein kinase – and mpf – m-phase promoting factor – pathways) and histological (meiotic spindle formation, polar body extrusion) aspects. finally, fertilization and early stages of development (up to one week) were studied. in another work, we demonstrated that chloride metal exposure affects oocyte survival with both morphological and electrophysiological methods. here, oocytes survival was considered by a new physiological method: the ability to undergo maturation after hormonal (progesterone) stimulation i.e. the gain for the oocytes to be competent for fertilization. in a second set of experiments, after cadmium exposures, we demonstrated that mpf pathway (associated with oocyte maturation) is deregulated. fertilization was then assessed when male and female gametes were, together or separately, exposed to cadmium. our data showed that cadmium exposure was responsible for adverse effects in a dose dependent manner on in vitro fertilization rates, development and organogenesis. in addition, our results showed that cadmium preferentially targeted the female gamete rather than spermatozoon, and prevented them to be fertilized. taken together, our results demonstrated that early stages of amphibians could be critical windows of exposure to cadmium.},

abstract = {As well as for air and waters, not only 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 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, obtained genotoxicity results after these exposures will be detailed. we will try to discuss the interests and limits of our environmental genotoxicity marker and to conclude if it is useful and relevant to monitor anthropic contaminated soils.},

	Accordingly, many geothermometers based on their composition, either 

	empirically or thermodynamically, have been proposed during the last 

	30 years, especially in low-temperature contexts (T < 350°C). This 

	paper presents a graphical tool that considerably facilitates the 

	use of two of the most recent chlorite thermometers for low- and 

	very-low-T chlorites. The temperature–composition relationships for 

	low-T chlorites are represented in T–Si– R2+ diagrams, allowing chlorite 

	compositions to be predicted as a function of temperature or, conversely, 

	temperature to be estimated from compositional fields of natural 

	chlorites. This graphical projection is based on a comparison of 

	the parameters (ideal chlorite compositions and calculated T) predicted 

	by geothermometers with analyses of natural chlorites for which independent 

	T estimates are available over a range of geological environments. 

	The new T–Si– R2+ diagram provides a practical tool for thermometric 

	purposes in the applicability range of the considered models, in 

	particular for diagenesis and low-grade metamorphism.},

abstract = {Soil microbial composition may vary in response to changes in organic matter inputs or stand compositions. boreal soils from alberta, canada, support a canopy cover of aspen (populus tremoloides michx.), white spruce (picea glauca (moench) voss) or a mixing of these two species. these soils also reflect different biogeochemical processing of organic matter degradation. this study sets out to determine if a simple labelled compound (13c glucose) and more complex labelled litter (13c leaves, or roots) are processed differently by forest floors from these two dominant stand types (aspen and spruce). to examine these effects, we put in place a lab incubation experiment, and added labelled substrates (glucose, roots or leaves) to a small quantity of moistened aspen or spruce forest floor. we measured soil respiration throughout the 67-day incubation, and used phospholipid fatty acids (plfa) analysis to identify the soil microbial structure. by quantifying the incorporation of 13c into different plfas, we were also able to identify functional groups responsible for the metabolism of labelled compounds. the measure of 13c-co2 gave some information about the percent of co2 coming from each added substrate. preliminary results indicate that daily respired co2 fluxes were more important from spruce than from aspen forest floor; this was true for all added substrates. for the spruce samples, co2 fluxes decreased very rapidly during the first four days, and stayed relatively constant during the remainder of the incubation. for the aspen samples, fluxes also decreased very rapidly during the first four days, and decreased more gradually for the rest of the incubation. results also show that both soils rapidly incorporated and respired the simple labelled carbon; indeed, after two days between 40 and 60 % of the added glucose had been respired against only 20 to 30 % for the more complex substrates (roots and leaves). the two soils maintained a distinct microbial community structure throughout the 67-day incubation. while the microbial structure changed during incubation, there was no measurable shift in response to substrate addition (labelled glucose, leaves or roots). finally, results show that the percent of substrate incorporated into microbial plfas was more important for the labelled roots than for the other two labelled substrates (glucose or leaves).},

	process. That means that the groundwater storage exhibits a memory

	storage. The Bayesian approach presented in this paper makes it possible 

	to give a probabilistic meaning to recession flow equations derived 

	according to a physical approach and can be an alternative to the 

	study of complex reservoir for which the physical processes governing 

	recession flow are unclear. Twelve spring recession flow series are

abstract = {Few studies have been conducted using xenopus laevis germ cells as oocytes, though these cells offer many advantages allowing both electrophysiological studies and morphological examination. our aim was to investigate the effects of metal (cadmium, lead, cobalt and zinc) exposures using cell biology approaches. first, cell survival was evaluated with both phenotypical and electrophysiological approaches. secondly, the effect of metals on oocyte maturation was assessed with morphological observations and electrophysiological recordings. from survival experiments, our results showed that metal chlorides did not affect cell morphology but strongly depolarized x. laevis oocyte resting potential. in addition, cadmium chloride was able to inhibit progesterone-induced oocyte maturation. by contrast, zinc, but also to a lesser extent cadmium, cobalt and lead, were able to enhance spontaneous oocyte maturation in the absence of progesterone stimulation. finally, electrophysiological recordings revealed that some metal chlorides (lead, cadmium) exposures could disturb calcium signaling in x. laevis oocyte by modifying calcium-activated chloride currents. our results demonstrated the high sensitivity of x. laevis oocytes toward exogenous metals such as lead and cadmium. in addition, the cellular events recorded might have a predictive value of effects occurring later on the ability of oocytes to be fertilized. together, these results suggest a potential use of this cellular lab model as a tool for ecotoxicological assessment of contaminated fresh waters.},

abstract = {The present study reports data on co2-rich geothermal waters and their associated carbonate deposits from the sw part of the permian lodève basin (south of france). both waters and carbonates are enriched in 226ra, with activities up to 2.2 bq/l and 3.5 bq/g respectively. a series of carbonate samples precipitated around the studied wells since 1990 were dated through the 226ra–210pb and 228ra–228th methods, and the results are discussed in a new concordia diagram. while both methods give comparable dates for many samples, ra–pb ages are sometimes much older than ra–th ages. we propose that these discrepancies result from the adsorption of 222rn daughter nuclides in such a rn-rich environment. the (228ra/226ra)0 activity ratios calculated at the time of deposition are remarkably constant for about 12 years, suggesting the presence of a steady-state aquifer. the low (228ra/226ra)0 ratios (0.348 ± 0.008) are best explained if most of the ra derives from the cambrian carbonate series (mainly dolostone) underlying the permian basin, which have low th/u and similar (228ra/226ra) ratios. this study suggests that ra and other alkaline-earth elements do not necessarily originate from the rocks surrounding the deep geothermal reservoir, but rather may be introduced into the co2-rich water during its transfer towards the surface and interaction with carbonate rocks},
