Full textThis study deals with the catalytic oxidation of 1-methylnaphtalene (1. MN) a modele molecule of polycyclics aromatics hydrocarbons (PAHs) over USHY faujasite zeolite doped or not with platinium. The aim of this study was the use of the USHY zeolite as catalytic filter for the destruction of persistant organic pollutants (POPs) fromm incineration processes. In a first time we evaluated the potential of the USHY zeolite for the destruction of 1-MN alone into carbon dioxide and water, then in the presence of 1. 2-dichlorobenzene, a precursor of dioxin and finally in the presence of a complex mixture of HCI, NO, SO2 and NH3

Full textLaying hens are likely to be exposed to a wide range of persistent organic pollutants (POPs) potentially present in their environment. In the context of securing poultry farming systems regarding POPs, our research has focused on identifying and grading factors likely to influence the transfer of ingested POPs to eggs. These factors are related to the nature of the ingested matrix (soil or feed), to the characteristics of the animal (laying rate, fatness) and to the properties of the molecule (lipophilicity, sensitivity to metabolism). Different scientific approaches have been implemented: in vivo experimentation and mathematical modeling. In the frame of in vivo experiments we have assessed the relative bioavailability of PCBs from one naturally contaminated soil. In addition, we have calculated parameters of the kinetics of transfer to eggs of molecules that had never been studied in laying hens, such as emerging molecules (for example a brominated flame retardant, HBCD), or PAHs. Our results point out the dominant impact of the molecule metabolism on the shape of its kinetics and on its rate of transfer to eggs.The developed dynamic mathematical model makes it possible to pilot variations with time of the size of the lipid compartments in the animal and of the frequency of laying. It was used to assess the influence of these animal characteristics on the transfer of POPs to eggs. Laying rate proportionally influences the contamination level of eggs and of animal tissues at steady state. Body fat dilutes absorbed POPs in absence of laying and significantly influences the rate of decontamination of tissues during depuration subsequent to an exposure period

Full textEpidemiological studies have shown that exposure to certain xenobiotics is associated with an increased prevalence of metabolic diseases. Humans are exposed to mixtures of xenobiotics in a chronic and inevitable way. We studied the effects of the interaction of two xenobiotics on metabolism in the liver, the major organ for detoxification in the body. We chose two endocrine disruptors and persistent organic pollutants which activate different signaling pathways: 2,3,7,8 tetrachlorodibenzo-p-dioxin (TCDD), which uses the AhR (Aryl hydrocarbon receptor) pathway, and α-endosulfan, an organochlorine pesticide, which acts via the PXR (pregnane X receptor) and/or the ER (estrogen receptor) pathway. Our aim was to determine the effects of this pollutant mixture, as compared to each pollutant alone, on the regulation in vitro of some hepatic metabolism pathways in the human hepatic cell line, HepaRG. In the first publication, a transcriptomic study of differentiated HepaRG cells was performed. The cells were exposed for 30h to 25nM TCDD, to 10 µM α-endosulfan or to the mixture. We observed that the mixture strongly inhibited the expression of some genes involved in the metabolism of glucose and alcohol. In the second study, we studied the mechanism of action of the mixture of pollutants on the metabolism of glucose. The expression of two genes involved in hepatic gluconeogenesis, glucose transporter 2 (GLUT2) and glucose-6-phosphatase (G6Pc), were reduced 80% by the mixture. The expression of other glucose metabolism genes (pyruvate kinase, glycogen synthase, glycogen phosphorylase, pyruvate dehydrogenase 2) also was decreased suggesting that the mixture might impact markedly carbohydrate metabolism. Furthermore, glucose production decreased 40% with the mixture under gluconeogenic conditions. Under glycolytic conditions, the oxidation of glucose into CO2 decreased 30% after 72h of exposure of the cells to the mixture. Long-term treatment (8 days) with lower doses (0.2 to 5 nM TCDD, 3 µM α-endosulfan) similarly decreased G6Pc and GLUT2 expression. We showed that TCDD activated the AhR pathway, and that ER was partly involved in the α-endosulfan effect. In the third part of this thesis, we studied the regulation of several enzymes involved in the metabolism of alcohol (alcohol dehydrogenase, ADH, cytochrome P450 2E1, CYP2E1) after activation of AhR. AhR agonists led to a decrease in the amounts of mRNAs for ADH1, 4, 6 and CYP2E1 and the corresponding proteins. We showed that this regulation uses the AhR genomic pathway. Furthermore, this effect was also observed after 8 days of treatment with lower doses of TCDD. Chronic exposure of individuals to low doses of xenobiotics in mixtures might significantly affect hepatic carbohydrate metabolism and be a contributing factor for the development of the metabolic syndrome

Full textEndometriosis is a gynecological disease for whichexposure to some environmental chemicals is evocatedamong the associated risk factors. Epidemiological studies are however globally non convergent and finally fairly conclusive. Their heterogeneity in terms of lesion localization and sub-phenotype, methodology, size and nature of the populations studied, as well as the limited number of monitored markers of exposure contribute to this situation. We realized a matched case-control study based on a biocollection of 113 patients including 68 patients suffering of deep endometriosis and 45 controls. We characterized the internal exposure levels of an extended range of around 78 persistent organic pollutants (including dioxins, polychlorobiphenyls, brominated flame retardants and organochlorine pesticides). Internal level exposures were measured in three biological compartments (omental fat, subcutaneous fat and serum). First, the distribution of these chemicals was characterized within these compartments. These extended exposure data from deep infiltrating endometriosis patients are the first ones available for France and give a new insight about the equilibrium of chemicals between storage and circulating compartments that should be further considered as a potential indicator permitting to establish a possible association between a chronic exposure to chemical hazards and human pathology. Afterwards, some of the targeted chemicals appeared significantly associated with deep endometriosis. A sub-stratification of our case population indicated a more significant relationship with the presence of endometrioma. Underlying mechanisms remain to be determined

Full textSoil contamination by organochlorine pollutants is a problem for ecosystem and human health. lt is not always possible to degrade these persistent molecules. The challenge is to prevent their adverse effects on the biota or their migration to other compartments of the agroecosystem. The use of nanoporous carbonaceous materials originated from plants can be one way. The objective of this thesis is ta select from a panel of carbon matrices those capable of effectively trapping contaminants such as polychlorinated biphenyls (PCBs), polychlorinated dibenzo-dioxins and furans (PCDD/Fs), as well as chlordecone (CLD). These matrices differ from each other by their properties (biochar vs activated carbon), conditioned by the pyrolysis and/or activation process used, as well as by the nature of the raw material used. The challenge is to produce, characterize and select the most efficient carbonaceous materials to maximize this sequestration. ln vitro environmental availability or bioaccessibility tests were used to perform a screening and then in vivo tests were set up to validate the effectiveness on a small number of carbonaceous materials. The in vivo tests were developed on three models of biota. An interaction emerges between the type of test, the carbon matrix used and the contaminants. lt appears that the effectiveness of the strategy depends on the target biota or the assessment method used. Regarding contaminants, it appears that the structure of the molecule could be at the origin of different behaviours. Regarding carbonaceous matrices, activated carbons were more efficient than biochars. Specific surface and microporosity are necessary conditions for the efficiency of activated carbons and mainly explain the difference in efficiency between biochars and activated carbons
