Évaluation de la contamination de l'estuaire de la Loire par des perturbateurs endocriniens : un risque potentiel pour la reproduction d'une espèce en danger : l'anguille Européenne (Anguilla anguilla L.) ? by Isabelle Blanchet-Letrouvé( Book )

2 editions published between 2014 and 2015 in French and held by 2 WorldCat member libraries worldwide

L'estuaire de la Loire subit des modifications liées à l'exposition potentielle de contaminants type perturbateurs endocriniens (PE). Polychlorobiphényles(PCB) et Polychlorodibenzodioxines/furanes(PCDD/PCDF) sont concernés. Cette thèse a pour objectif:1/ d'évaluer la contamination de l'estuaire par ces PE et d'estimer les éventuelles perturbations sur Anguilla anguilla, du juvénile à l'adulte; 2/ mettre en évidence des liens de cause à effets potentiels entre la présence de PE et l'imprégnation dans les muscles et gonades, 3/évaluer les atteintes de la reproduction via des biomarqueurs [Vitellogénine (Vg) et aromatase]. L'existence et l'omniprésence de PE dans les sédiments de l'estuaire a été montrée avec des variations inter-site de St-Nazaire à Ancenis. Les analyses chimiques sur les organismes ont permis de souligner leur contamination significative en PCB, PCDD et PCDF, quelle que soit la classe de taille et le stade de maturité sexuelle ; les gonades étant dans l'ensemble plus contaminées que les muscles. Un lien fort entre le pourcentage de lipides et ces composés lipophiles est apparu, les lipides étant notamment nécessaires à la migration de reproduction, la vitellogenèse et l'ovogenèse. La quantification de l'expression de la Vg chez l'anguille montre que 38 % des individus présentent une expression non attendue. Les analyses en composantes principales établissent des corrélations entre PCB, % de lipides, coefficient de condition et anguilles jaunes juvéniles. Il n'existe pas de corrélation nette entre les biomarqueurs, Vg et aromatase, les niveaux de contamination en PCB et l'histologie des gonades. (1593 carac)

Recherche d'indicateurs de l'état physiologique de l'annélide polychète endogée Nereis diversicolor en relation avec la qualité du milieu by Cyril Durou( Book )

1 edition published in 2006 in French and held by 2 WorldCat member libraries worldwide

Risk assessment in estuarine ecosystems is mainly limited due to the lack of both biological indicators for the sediment and knowledge about invertebrate physiology (particularly of reproduction). In situ, conservation of invertebrate population strongly depends upon individual health status. A multi-parameter methodology was applied to Nereis diversicolor, a key species of the sediment, recommended in biomonitoring programs. Physiological indicators (size - weight relationships, reproduction status, energy reserves) are proposed to assess the biological quality status in estuarine ecosystems. Moreover, this work links for the first time levels of energy reserves (glycogen, lipids), sexual maturity stage and level of steroid hormones (progesterone, 17[beta]-œstradiol and testosterone)
Approche multi-marqueurs pour l'évaluation de l'état de santé du golfe de Tunis : étude des réponses biochimiques, physiologiques et cytologiques des mollusques bivalves exposés aux effluents des oueds by Sofiène Tlili( )

Research in ecotoxicology currently focuses to fill the gap existing between sub-organismal responses (e.g. biomarkers) to toxicants and effects occurring at higher levels of biological organisation (e.g. population). In this context, the main objective of this PhD thesis was to contribute to the eco-toxicological risk assessment of the Gulf of Tunis across the use of the intra-sedimentary bivalve Donax trunculus. A battery of biomarkers measured at different level of biological organization (biochemical, physiological and population) was assessed. Links between the responses at the infra-individual level (core biomarkers) to supra-individual level (structure and population's dynamic) were depicted. Results of biochemical markers were incorporate into two biomarkers integrated indices (Integrated Biomarker Response: IBR and Health Status Index: HIS). Finally, a new biomonitoring tool based on the combined use of reproduction endpoints, allometry relationships and biological indices was proposed and discussed

Étude chez l'huître creuse, Crassostrea gigas, des anomalies génomiques provoquées par l'exposition à des concentrations environnementales de diuron : caractérisation des atteintes, étude de leur héritabilité et conséquences pour la survie et la croissance des naissains by Audrey Barranger( Book )

2 editions published in 2015 in French and held by 2 WorldCat member libraries worldwide

The aims of this PhD were to determine (1) the effects of the herbicide diuron on the genome of the oyster, Crassostrea gigas, (2) the possible transmission to the offspring of damaged DNA and (3) its consequences on oyster physiology. The genotoxicity of diuron and the vertical transmission of DNA damage were highlighted after parental exposure to environmental concentrations of diuron during the gametogenesis. Primary DNA lesions were detected in both somatic cells and germ cells of exposed genitors. Detection of the oxidized base 8-oxodGuo in gonads shows that exposure to diuron led to an oxidative stress which likely explains the observed DNA strand breaks in spermatozoa. The transmission of these DNA damage was confirmed by fluorescent in situ hybridization: aneuploid nuclei were detected in embryos from diuron-exposed genitors. This hyper- and hypodiploidy particularly concerns 5S and 18-5.8-28S ribosomal genes localized on chromosomes 4, 5 and 10. Flow cytometry analysis showed survival of hypodiploid individuals at spat stage. This vertical transmission of damaged genetic material is associated with deleterious effects on the physiology of the offspring (developmental defects, growth retardation). Data acquired during this PhD contribute to a better understanding of the long-term effects of exposure to genotoxic pollutants. In the context of massive mortality outbreaks, the presence of chemical pollutants may contribute to a weakening of oysters in case of the presence of pathogens or adverse physicochemical environmental conditions

Évaluation de la contamination des sédiments et de l'anguille européenne (Anguilla anguilla) dans l'estuaire de la Loire par des substances chimiques de type perturbateurs thyroïdiens et interprétation en termes d'écotoxicité et de risque sanitaire by Mickaël Couderc( Book )

2 editions published in 2014 in French and held by 2 WorldCat member libraries worldwide

Parmi les perturbateurs endocriniens, les composés agissant sur le système thyroïdien n'ont été étudiés que récemment malgré l'importance majeure de cette fonction dans de nombreux processus physiologiques de l'organisme (e.g. croissance, métabolisme, développement). L'estuaire de la Loire est un espace soumis à de fortes pressions anthropiques, sources de contaminations potentiellement néfastes au fonctionnement du système thyroïdien des organismes vivants et de l'Homme. Dans cette étude, six familles de perturbateurs thyroïdiens (PT) potentiels ou avérés, les polychlorobiphényles (PCB), les polybromodiphényles éthers (PBDE), les substances perfluoroalkylés (PFAS), les alkylphénols (AP), les hydrocarbures aromatiques polycycliques (HAP) et le bisphénol A (BPA) ont été investigués. La présence de composés de type PT a été démontrée dans les sédiments de l'estuaire qui ont également révélé une activité perturbatrice appréciée par des tests in vitro. De par son importance écologique et économique, l'anguille européenne (Anguilla anguilla) a également été étudiée comme espèce sentinelle de la contamination chimique de l'estuaire. Chez cette espèce, des corrélations entre la présence de ces contaminants dans l'organisme et le statut thyroïdien (concentrations en hormones et expression génique) ont été trouvées. Enfin, dans le but de pouvoir déterminer les effets chez l'Homme d'une consommation de poissons contaminés, un focus spécifique en terme de caractérisation du danger ciblant l'un de ces contaminants, le 4-nonylphénol, a permis de mettre en évidence chez le rat une relation de causalité entre développement neurologique et exposition à cette substance chimique
Caractérisation du comportement de nanoplastiques représentatifs de l'environnement dans un gradient de salinité : évaluation de leurs impacts écotoxicologiques sur les huitres de palétuviers Isognomon alatus by Zélie Venel( )

1 edition published in 2020 in French and held by 1 WorldCat member library worldwide

Plastic pollution of surface water is constantly increasing and raises economic and ecological problems. According to recent studies, marine plastic debris breaks down into microparticles and nanoparticles by mechanical and photochemical processes. The nanometric fraction of environmental plastics is still unknown because there are still analytical challenges to characterize nanoparticles at trace concentrations. These particles are potentially toxic due to their composition, size and shape, but can become even more toxic, by aggregation with organic matter, or by surface adsorption of trace metals or organic contaminants. Up to date, there is limited studies about behavior of nanoplastics in transitional waters such as estuaries and mangroves. The aim of this thesis is to (i) characterize physico-chemical behavior of nanoplastic models in a salinity gradient, with an innovative methodology using microfluidics; (ii) study the ecotoxicological impact of these nanoparticles on bivalves, with an exposure representative of in situ conditions.Polystyrene latex, as well as mechanically aged nanoplastics from either pristine polystyrene pellets or from macro-plastics sampled on Guadeloupe beaches (polyethylene, polypropylene), were dispersed across a salinity gradient under dynamic conditions inside a microchip. Results were compared with conventional protocols i.e. dispersing standard nanospheres in a homogeneous saline medium under static conditions. Sizes, concentrations, morphologies, compositions and stability of these nanoparticles were measured as a function of the physicochemical conditions of the medium. Then, the ecotoxicological impact of model nanoplastics dispersed via a salinity gradient was studied on flat tree oysters: Isognomon alatus. Exposures were carried out by direct route at environmental concentrations. Different markers such as metallothionein production and early gene expression have been used to assess the toxicity of nanoplastics. This thesis also allowed the development of one of the most sensitive instruments for the analysis of nanoparticles at ultra-trace concentration: the Laser Induced Breakdown Detection (LIBD). This work highlights the impact of salinity gradients on the behavior of nanoplastics and its importance in the toxicity assessment on bivalves during the transition from freshwater to seawater
Effets (sub)individuels et fonctionnels des nanoparticules manufacturées sur des Crustacés Gammaridae by Jennifer Andreï( )

1 edition published in 2015 in French and held by 1 WorldCat member library worldwide

Products incorporating nanoparticles are now ubiquitous in our everyday life. For example, sunscreens, fuel additives or food packaging materials contain nanoparticles which could be released in the aquatic environment during the entire life cycle of the nanoproduct, from its production to its use and aging. Therefore an increase of nanoparticle emissions in the aquatic ecosystems needs to be considered and raises the question about their potential effects on living organisms. The collaborative program ANR P2N - MESONNET (2011- 2015) was focused on the evaluation of the nanoparticle fate (transfer and transformation in media and living organisms) and on their ecotoxicity. The present work took part in this assessment by studying the effects of nanoparticles of silver, titanium and carbon (nanotube) on the Crustaceans Amphipod Gammarus sp.. The experimental approach was designed to assess, in laboratory conditions, the effect of nanoparticles on the gammarids, focusing on biomarker measurements at the (sub)individual level (cellular, physiological, behavioral) and on some parameters related to their functional roles. Experiments were designed as close as possible to natural conditions using environmentally realistic contamination scenario: exposure in a complex media (natural water from river) to low nanoparticle concentrations and with food. In this context, the effects of nAg were investigated in three gammarids species and results revealed a higher sensibility of G. roeseli, for which exposure induced a decrease of the locomotor activity and of the production of fine particles of organic matter (FPOM). At the physiological level, an increase of the oxygen consumption was observed in gammarids exposed to nAg, despite a stability observed for the studied markers of energetic metabolism. The oxygen consumption was correlated with the silver concentration measured in the organisms, and also with the tested nanoparticle sizes. The influence of the nanoparticle forms (nAg: plate triangular and spherical; nTiO2: cubic and rod-shaped) and of the organic matter (CNT) was studied in mesocosms by focusing mainly on cellular indicators (energetic storage, antioxidant response, damage...) and individual ones (osmoregulation, ventilation and locomotion). The obtained results suggest form-dependent effects of nanoparticles. This work shows the interest of a coupled approach using ecological and ecotoxicological endpoints to better understand the effects of nanoparticles on freshwater ecosystems
Is there any consistency between the microplastics found in the field and those used in laboratory experiments?( )

1 edition published in 2016 in English and held by 1 WorldCat member library worldwide

Abstract: The ubiquitous presence and persistency of microplastics (MPs) in aquatic environments are of particular concern since they represent an increasing threat to marine organisms and ecosystems. Great differences of concentrations and/or quantities in field samples have been observed depending on geographical location around the world. The main types reported have been polyethylene, polypropylene, and polystyrene. The presence of MPs in marine wildlife has been shown in many studies focusing on ingestion and accumulation in different tissues, whereas studies of the biological effects of MPs in the field are scarce. If the nature and abundance/concentrations of MPs have not been systematically determined in field samples, this is due to the fact that the identification of MPs from environmental samples requires mastery and execution of several steps and techniques. For this reason and due to differences in sampling techniques and sample preparation, it remains difficult to compare the published studies. Most laboratory experiments have been performed with MP concentrations of a higher order of magnitude than those found in the field. Consequently, the ingestion and associated effects observed in exposed organisms have corresponded to great contaminant stress, which does not mimic the natural environment. Medium contaminations are produced with only one type of polymer of a precise sizes and homogenous shape whereas the MPs present in the field are known to be a mix of many types, sizes and shapes of plastic. Moreover, MPs originating in marine environments can be colonized by organisms and constitute the sorption support for many organic compounds present in environment that are not easily reproducible in laboratory. Determination of the mechanical and chemical effects of MPs on organisms is still a challenging area of research. Among the potential chemical effects it is necessary to differentiate those related to polymer properties from those due to the sorption/desorption of organic compounds. Highlights: The nature and quantities/abundance of MPs are not systematically determined in field samples. There is an urgent need to establish standardized protocols for sampling, sample preparation, MP analysis and data expression. Laboratory experiments are often performed with MP concentrations of a higher order of magnitude than those found in the field. MP exposure conditions usually involve only one type of polymer of a precise size and homogenous shape. MP exposure conditions are not consistent with the MPs present in the field (many types, sizes, shapes). Abstract : The microplastic contaminations employed in laboratory exposures are not consistent with the exposome in terms of concentration/quantity, nature, form or size
Relations "biodisponibilité-génotoxicité-écotoxicité" des hydrocarbures aromatiques polycycliques (HAP) dans les sols de friches industrielles by Marc Bonnard( )

1 edition published in 2010 in French and held by 1 WorldCat member library worldwide

The aim of this work research was to show in formerly-contaminated coking plant soils a relationship between the bioavailability of soil pollutants (PAH and/or heavy metals), their genotoxicity and their populational effects in the Eisenia fetida earthworm. This study showed that despite a similar contamination studied soils exhibited a great difference in ecotoxicity to earthworms and other terrestrial organisms (plants, springtails). Differences in ecotoxicity of soils would be attributable to bioavailability of soil pollutants which is different between soils. This study also showed that thermal desorption applied on one of the contaminated soils increased bioavailability of heavy metals. Thermal desorption would modify 1) the nature and composition of soil organic matter, 2) the speciation of heavy metals, 3) links between soil organic matter and heavy metals, rendering them more bioavailable and genotoxic to earthworms. The biological-ecotoxicological approach, which takes into consideration the bioavailability of soil pollutants, reveals to be necessary in addition of the physico-chemical approach in the evaluation of 1) risks and 2) remediation efficiency of contaminated soils. This study also showed that the measure of DNA damage in coelomocytes of earthworms is a relevant biomarker in the evaluation of genotoxicity of soil pollutants. This biomarker of genotoxicity can be used as indicator of bioavailability of soil pollutants. It revealed more sensitive than survival and as sensitive as reproduction, which are classical endpoints measured in earthworms. This biomarker of genotoxicity could be used as early indicator of physiological disturbances, even if the mechanistic link between DNA damage and effects on reproduction require further studies
