abstract = {En toxicologie génétique, le cadmium est un génotoxique reconnu et les mécanismes expliquant son caractère clastogène sont indirects : par l’induction d’espèces réactives de l’oxygène et/ou l’inhibition des mécanismes de réparation de l’adn. pour le plomb, l’ensemble des travaux publiés sont équivoques et ambigus voire contradictoires. concernant les effets clastogènes et mutagènes parfois reportés, ses mécanismes d’action ne sont pas clairs et probablement indirects. en génotoxicité environnementale, pour ses deux métaux, l’étude de leur caractère génotoxique, seuls ou en mélange et en sols naturels, est encore plus complexe car il faut également considérer: (1) les notions de disponibilité environnementale, de biodisponibilités environnementale et toxicologique, (2) leurs présences simultanées dans les sites et sols contaminés ou pollués (particulièrement dans le contexte régional du nord-pas-de-calais), (3) et alors leurs éventuelles interactions toxicologiques. le test des comètes est une technique de microélectrophorèse de noyaux de cellules isolées qui permet l’étude des dommages primaires à l’adn (cassures double et simple brin, sites alcali-labiles) au sein d’une population cellulaire. cet essai a été mis au point et validé avec les coelomocytes de notre modèle biologique, reconnu en écotoxicité des sols, eisenia fetida. dans une première phase d’expérimentation, nous avons réalisé des expositions in vivo (3 & 10 jours) en utilisant un sol péri-urbain caractérisé (et représentatif du contexte régional) artificiellement contaminé par du cadmium et/ou du plomb, à des concentrations environnementales et réalistes (entre 2,5 et 20 mg/kg de sol sec pour le cadmium et entre 250 et 2000 mg/kg pour le plomb, gammes de concentrations de raison 2). les principaux résultats, qui seront présentés de manière détaillée dans cette communication, sont les suivants : (1) nous observons des dommages à l’adn significatifs suite aux expositions au cadmium seul, sans relations temps-dépendante et/ou dose-dépendante ; (2) suite aux expositions au plomb, une légère augmentation du niveau de dommages à l’adn est observée, mais celle-ci n’est jamais significative : le plomb n’apparait pas comme génotoxique, plus précisément comme clastogène pour notre ver de terre ; (3) les dommages observés suite aux expositions aux différents mélanges cd/pb sont intermédiaires entre les cassures reportées suite aux expositions monométalliques. plusieurs hypothèses pourraient expliquer ces résultats dans le cas des expositions aux mélanges cd/pb (et des résultats complémentaires sont en cours d’acquisition pour les étudier): (1) une mise en place de mécanismes de défense contre les effets toxiques de pb, qui protégerait également les individus contre la génotoxicité de cd ; (2) des effets autres que clastogènes de pb qui masquerait la génotoxicité de cd ; (3) une faible biodisponibilité de pb dans le sol utilisé. a terme, des travaux avec des échantillons environnementaux (i.e. des sols contaminés prélevés in situ) seront également réalisés et confrontés aux résultats obtenus au laboratoire.},

abstract = {Contexte la loi du 9 août 2004 relative à la politique de santé publique avait fixé dans ses objectifs de « réduire de 50 % la prévalence du saturnisme infantile (plombémie j 100 kg/l), à savoir passer de 2 % en 1996 à 1 % en 2008 » (objectif n°18). l’indicateur retenu était « le nombre d’enfants de 1 à 6 ans ayant une plombémie j 100 kg/l en population générale et dans les groupes à risque ». en 1996, la prévalence du saturnisme infantile était de 84 000 enfants âgés de 1 an à 6 ans. cependant, seuls 500 cas sont déclarés chaque année. parallèlement, les données collectées par les outils réglementaires relatifs au plomb dans les logements ne sont pas centralisées ; l’état de la contamination en plomb ne peut alors être connu. ainsi, afin d’actualiser les données sur l’imprégnation saturnine infantile, l’institut de veille sanitaire (invs) a réalisé en 2007-2009 une enquête de prévalence du saturnisme chez les enfants de 6 mois à 6 ans. cette enquête a offert l’opportunité d’examiner, à travers une étude nationale complémentaire au domicile de près de 500 enfants, le lien entre la plombémie chez un enfant et les facteurs d'exposition de son environnement. l’enquête environnementale, dénommée plomb-habitat, permet d’avoir une meilleure connaissance de ces déterminants environnementaux, des modes d’occupation du logement et des comportements expliquant l’imprégnation. objectif le présent rapport fournit l’état de la contamination au plomb des logements français, construits avant ou après 1949, abritant au moins un enfant âgé de 6 mois à 6 ans, obtenu à partir de l’enquête plomb-habitat. méthode quatre cent quatre vingt quatre logements ont été enquêtés entre octobre 2008 et août 2009. un questionnaire a permis de collecter des informations relatives au ménage, au comportement de l’enfant et au logement. en outre, des prélèvements de plusieurs sources potentielles d’intoxication par le plomb ont été réalisés : eau du robinet, poussières du sol dans cinq pièces au maximum du logement, poussières du sol dans les parties communes le cas échéant, écailles de peinture et sol extérieur sur l’aire de jeu de l’enfant. des mesures à fluorescence x des revêtements de chaque pièce investiguée ont complété les investigations. l’analyse descriptive réalisée a pris en compte les poids de sondage, permettant ainsi des estimations au niveau national, et a tenu compte du plan de sondage permettant de calculer des incertitudes sur ces estimations. la population de logements ciblée est composée de 3 581 991 unités. l’influence de certains facteurs (âge et localisation du logement, caractéristiques constructives, etc.) sur le plomb présent dans le logement a été testée. la concordance mesure xrf versus concentration massique en plomb dans la peinture a été testée. les ratios concentration en plomb acido-soluble sur concentration en plomb total ont été calculés dans les différents médias.},

abstract = {To assess the toxicity of a soil contaminated with landfill leachate, biomarker measurements in two species living in close contact with the soil, i.e. a plant species trifolium repens and an animal species eisenia fetida, were conducted. briefly, both species were studied after simultaneous exposure conducted in microcosms. the organisms were exposed to soil supplemented with pure leachate, leachate diluted to 50%; leachate diluted to 25% and without leachate. after a 10 weeks exposure period, we observed an increase in the olive trail moment in t. repens, compared to the reference, for 50% and pure leachate. the response observed appears to be dose-dependent and linear in our experimental conditions. addition of the leachate to the reference soil induced an increase in cd-metallothionein-coding mrna quantity in e. fetida. in addition, expression level of another gene implied in detoxification and coding phytochelatin synthase was significantly induced in worms exposed to the reference soil spiked with the leachate, regardless presence of t. repens. thus, t. repens and e. fetida can be used in a complementary manner to assess soil quality. sensitivities of the test species yield sensitive bioassays as both species responded at low doses despite the buffering effect of the soil.

abstract = {In this study, monitoring and thermodynamic approaches were combined in order to identify the dominant features, which control the speciation of cd, cu, pb, and zn in solutions from unpolluted planosolic soil (north massif central, france). three sites were selected according to topography and monitored from january to may 2006 using piezometers. the sandy-loam to clay-loam organic-rich horizon (horizon a) and the gravely and concretion-rich horizon (horizon e) were chosen to assess the potential impact of type of horizon on the chemical speciation of metals in the soil solutions. binding of metals to organic ligands was studied by differential pulse anodic stripping voltammetry (dpasv) in order to acquire experimental data which could be used for the validation of speciation models. these data, together with data from the literature on properties of natural particulate matter, were used to determine the speciation of cd, cu, pb and zn with a thermodynamic code (phreeqc). the observed and predicted speciation were compared to estimate the contributions of natural dissolved organic matter and of particles to the binding of metal ions. there was a good match between observed and predicted results, validating the approach used. results show that particles (mixed iron and aluminium oxides ± clays ± organic matter) play the main role in the speciation of the trace metals in soil waters rather than complexation with dissolved organic matter. moreover, particles govern speciation to a greater extent in horizon e than in horizon a, which can be linked to hydrodynamics (reaction time between water and soil due to porosity) and chemical reactivity of the solution circulating dans cette étude, deux approches (approche terrain et approche thermodynamique) ont été couplées pour étudier la spéciation de cd, cu, pb et zn dans des eaux de subsurface circulant dans un sol non anthropisé de type planosol (nord du massif central, france). trois stations ont été sélectionnées sur un transect topographique au niveau desquelles les eaux du sol ont été prélevées de janvier à mai 2006. l’horizon éluvial appauvri et blanchi (horizon a) et l’horizon concrétionné riche en oxyhydroxydes de fer et de manganèse (horizon e) ont été choisis afin d’évaluer l’impact potentiel de la nature de l’horizon sur la spéciation chimique des métaux dans les solutions de sol. les affinités potentielles des métaux avec les ligands organiques ont été déterminées expérimentalement par voltamétrie (dpasv) ; celles avec les matières particulaires naturelles ont été prises dans la littérature. l’ensemble de ces données a été utilisé pour déterminer la spéciation de cd, cu, pb et zn par calcul thermodynamique (phreeqc). la spéciation des métaux prédite par le modèle a été comparée à celle observée sur le terrain afin d’estimer les contributions des composés organiques dissous et des particules minérales et/ou organiques vis-à-vis de cd, cu, pb et zn. les résultats obtenus (prédits/observés) sont en accord et permettent de valider l’approche proposée. les résultats montrent que les métaux traces étudiés ont des affinités beaucoup plus fortes pour les réactions de surface avec les particules mixtes (oxydes de fer et d’aluminium ± argiles ± matière organique) que pour les réactions de complexation en solution avec les composés organiques dissous. la régulation de la spéciation par la phase particulaire est plus forte dans l’horizon e que dans l’horizon a, et est principalement liée à la texture du sol (et donc la porosité) et à l’hydrodynamique du système},

abstract = {Ce présent rapport porte sur la réalisation d’une nouvelle campagne de mesures des concentrations en plomb et en cadmium dans les sols et les productions végétales qu’elles soient agricoles ou potagères dans la zone à plus de 200 mg de plomb kg‐1 autour de l’ancienne fonderie de plomb metaleurop nord (evin‐malmaison, courcelles les lens, noyelles‐godault, dourges, ostricourt, leforest et auby). la démarche vise à conforter ou redéfinir le périmètre du pig (établi en 1999) sur la base de données acquises sept ans après l’arrêt des activités de l’usine. les concentrations en plomb et en cadmium ont été mesurées dans l’horizon organo‐minéral (0 ‐ 25 cm) en 328 points répartis sur l’ensemble du secteur concerné (228 sols agricoles et 100 sols urbains). en parallèle, la teneur en ces deux éléments a été mesurée dans 303 prélèvements de végétaux (95 plantes agricoles et 208 plantes potagères). des semences et plants de variétés identiques ont été distribués aux jardiniers. les végétaux ont été préparés en fonction de leur destination et seules les parties habituellement consommées ont été analysées. la mesure des concentrations totales en pb et cd des sols et des végétaux a été confiée à l’inra. l’analyse statistique des concentrations totales en pb et en cd (campagne 2010 et campagnes antérieures) n’a pas mis en évidence une évolution notable du degré de contamination des sols depuis l’arrêt de l’activité. les sols présentent toujours aujourd’hui des concentrations totales en pb et cd qui dépassent d’une façon significative les teneurs agricoles habituelles régionales. l’analyse géostatistiques réalisée sur l’ensemble des informations acquises depuis l’arrêt des émissions de l’usine (plus de 1 000 données) atteste d’un fort degré de contamination de l’horizon organo‐minéral, d’une contamination plus importante des sols urbains et des habitats ligneux, de l’existence de « hot spots » de contamination (gare d’eau de courcelles les lens, site de stockage des boues de curage de la deûle). en comparaison des travaux antérieurs, l’accroissement du nombre de données analytiques a permis de préciser les courbes d’isoconcentration en pb et cd des sols. au regard de la réglementation en vigueur, la production agricole de végétaux pour l’alimentation humaine reste préoccupante dans la zone où les concentrations excèdent 4 mg de cadmium kg‐1 (grain de blé, d’escourgeon, féverole et betterave sucrière). la plupart des productions sont toutefois conformes pour l’alimentation animale (sauf les pailles de céréales et le maïs fourrager). la production de légumes au niveau des potagers est beaucoup plus problématique, ils sont souvent non‐conformes pour l’alimentation humaine. les plus cultivés (carotte, pomme de terre et poireau) sont d’ailleurs ceux qui présentent les plus forts taux de non‐conformité. de manière générale, la situation est plus préoccupante en ce qui concerne les concentrations totales en cd observées dans les végétaux qu’ils proviennent de l’agriculture ou des potagers. la situation environnementale a peu évolué depuis l’arrêt de l’activité de l’usine. des denrées alimentaires non‐conformes sont actuellement mises sur le marché. le dispositif en place devrait être renforcé pour garantir la sécurité alimentaire tout en assurant l’avenir de l’agriculture dans la zone concernée. les mesures de gestion devraient être étendues à partir de la zone qui présente des concentrations supérieures à 200 mg de pb kg‐1 et/ou à 4 mg de cd kg‐1.pour les sols urbains une stratégie de remédiation des sols selon leurs usages et les dangers pour les populations devrait être mise en place. attendues des populations locales, ces actions devraient être concomitantes d’un engagement des instances régionales, de la volonté et de la concertation des gestionnaires territoriaux.},

abstract = {Concepts and developments for a new field in ecotoxicology, referred to as ‘‘landscape ecotoxicology,’’ were proposed in the 1990s; however, to date, few studies have been developed in this emergent field. in fact, there is a strong interest in developing this area, both for renewing the concepts and tools used in ecotoxicology as well as for responding to practical issues, such as risk assessment. the aim of this study was to investigate the spatial heterogeneity of metal bioaccumulation in animals in order to identify the role of spatially explicit factors, such as landscape as well as total and extractable metal concentrations in soils. over a smelter-impacted area, we studied the accumulation of trace metals (tms: cd, pb and zn) in invertebrates (the grove snail cepaea sp and the glass snail oxychilus draparnaudi) and vertebrates (the bank vole myodes glareolus and the greater white-toothed shrew crocidura russula). total and cacl2-extractable concentrations of tms were measured in soils from woody patches where the animals were captured. tm concentrations in animals exhibited a high spatial heterogeneity. they increased with soil pollution and were better explained by total rather than cacl2-extractable tm concentrations, except in cepaea sp. tm levels in animals and their variations along the pollution gradient were modulated by the landscape, and this influence was species and metal specific. median soil metal concentrations (predicted by universal kriging) were calculated in buffers of increasing size and were related to bioaccumulation. the spatial scale at which tm concentrations in animals and soils showed the strongest correlations varied between metals, species and landscapes. the potential underlying mechanisms of landscape influence (community functioning, behaviour, etc.) are discussed. present results highlight the need for the further development of landscape ecotoxicology and multi-scale approaches, which would enhance our understanding of pollutant transfer and effects in ecosystems.},

abstract = {This study compares two methods to immobilise the same amount of zn in cement paste. in the first method, zn is introduced into the raw material before clinkerisation, whereas in the second process, zn is introduced in the liquid phase used to make the cement paste, which is often referred to as solidification/stabilisation. in laboratory-made clinker, zn was mainly fixed within a new compound (ca6zn3al4o15). also, zn was observed in tricalcium silicate (c3s) and in the interstitial phase (c3a and c4af) with the exception of dicalcium silicate (c2s). in the present study, the threshold limit value corresponds to the maximum amount of zn that could be incorporated without the stability of the clinker phases being modified. this threshold was reached when a decrease in c3a content and/or the presence of ca6zn3al4o15 were observed by x-ray diffraction. the threshold limit of zn in the studied clinker was established at 0.7% by weight. the reactivity of synthesised cement doped with zn was studied by isothermal calorimetry measurements. these tests revealed that the incorporation of zn had no effect on calcium silicate hydration (c3s and c2s), even if the zn content exceeded the threshold limit value, i.e., 1%. these results were compared with those obtained through the solidification/stabilisation treatment of zn in a cement paste. in these experiments, a zn content of 0.7% induced a significant delay in the cement hydration. this difference in behaviour is due to the slower flow of zinc ions released in solution when it is incorporated in the clinker phases. thus, the immobilisation during clinkerisation is a good alternative to treat waste with a high zn content in ordinary portland cement (opc) without causing the well-known, deleterious effect on cement setting time},

abstract = {In orogenic systems, thrust faults play a major role in stacking different tectonic units and may act as conduits for the expulsion of large amounts of fluid of different origins (metamorphic, diagenetic, meteoric). this study focuses on the monte perdido thrust unit emplaced in the paleogene jaca thrust-sheet-top basin, in the sw-central pyrenees. we aim to decipher the mechanisms and p-t conditions of deformation in fault zones and characterize the related fluid involvement, through combined microstructural, geochemical and microthermometry analyses. two thrust faults cutting platform limestones, marls and siliciclastic turbidites of the lower part of the basin-fill (paleocene–lower eocene) have been studied. the fault zones are characterized by metre-thick shear zones with highly deformed, foliated clay-rich sediments. foliation is underlined by preferentially oriented phyllosilicates. several generations of shear and extension calcite, quartz and chlorite-bearing veins attest to fluid-rock interactions during a multi-stage deformation. microstructural observations and stable isotope analyses on calcite from veins and host sediments suggest that deformation was aseismic and dominated by diffusive mass transfer from pressure solution sites along cleavage and stylolites to the precipitation sites in veins, with mineralizing fluids in equilibrium with the host sediments. our results suggest an essentially closed hydrologic system, and imply the absence of significant fluid flow along the studied fault zones. microthermometric study on fluid inclusions present in calcite and quartz veins, and calcite-quartz oxygen isotopic fractionation determined for the first generation shear veins, allow a geothermal gradient of 34â â°c/km to be estimated. analytical results demonstrate an evolution of the fault zones in three stages. the first stage was related to the emplacement of the monte perdido thrust unit during the middle eocene at a temperature of ∼208â â°c and a burial depth of ∼5.7â km. the second stage corresponds to a fault reactivation at a temperature of ∼240â â°c and a burial depth of ∼6.5â km. the latter deformation may have been related to folding of the monte perdido thrust unit during the emplacement of the underlying gavarnie thrust unit during the late eocene–early oligocene, with deeper burial resulting from aggradation of the thrust-sheet-top basin-fill. the last event corresponds to the formation of a dilatant vein system likely related to the exhumation of the massif. %z acl %u http://www.sciencedirect.com/science/article/pii/s0191814111001039 %+ %^},

abstract = {Aided phytostabilisation is a cost efficient technique to manage metal contaminated areas, especially in the case of extensive pollution. however, plant establishment and survival in highly metal-contaminated soils is crucial for phytostabilisation success, as metal toxicity for plants is widely reported. appropriate phytostabilisation technique should also limit metal transfer through the food chain. in this context, this study aimed at evaluating the long-term efficiency of aided phytostabilisation on former agricultural soils highly contaminated with cadmium, lead and zinc. the influence of afforestation and fly ash amendments to reduce metal phytoavailability was investigated as well as their effects on plant development. before being planted with a tree mix, the study site was divided into three plots: a reference plot with no amendment, the second amended with silico-aluminous fly ash and the third with sulfo-calcic fly ash. our data show that, unlike salix alba and quercus robur, alnus glutinosa, acer pseudoplatanus and robinia pseudoacacia have well grown on the site and accumulated overall quite small quantity of metals in their leaves and young twigs. this suggests that these three species are suitable for phytostabilisation of metal contaminated soils. after eight years, results also demonstrated that fly ash amendments strongly decreased te availability to a. glutinosa, a. pseudoplatanus and r. pseudoacacia, and translocation to above-ground parts. these decreases fit well together with the cacl2 extractability depletion of metal in amended soils. if both fly ashes are interesting to decrease cd, pb and zn concentrations in above-ground parts of trees, the sulfo-calcic ash is more efficient.},

abstract = {Sustainable management of large surface areas contaminated with trace elements is a real challenge, since currently applied remediation techniques are too expensive for these areas. aided phytostabilisation appears to be a cost efficient technique to reduce metal mobility in contaminated soils and contaminated particle spread. in this context, this study aimed at evaluating the long-term efficiency of aided phytostabilisation on former agricultural soils highly contaminated with trace elements. the influence of afforestation and fly ash amendments to reduce metal mobility was investigated. before being planted with a tree mix, the study site was divided into three plots: a reference plot with no amendment, the second amended with silico-aluminous fly ash and the third with sulfo-calcic fly ash. after eight years, some soil physico-chemical parameters, including cadmium (cd), lead (pb) and zinc (zn) extractability were modified. in particular, ph decreased on the whole site while organic carbon content increased. the alteration of these parameters influencing trace element mobility is explained by afforestation. over time, concentrations of cacl2-extractable metals increased and were correlated with the soil ph decrease. in the amended soils, extractable cd, pb and zn concentrations were lower than in the reference soil. the results indicated that the two fly ashes buffered natural soil acidification due to vegetation development and limited trace element mobility and thus could limit their bioavailability. for long-term phytostabilisation, special attention should be focused on the soil ph, metal mobility and phytoavailability analysis.
