Повний текст джерелаLaying 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

Повний текст джерелаThe industrial revolution, technological change, population growth and urbanization have affected not only the economy and politics all around the world but also the environment. Various types of pollutants are generated and introduced permanently into the environment through industrial, agricultural and/or municipal discharges. These pollutants include the persistent organic pollutants or POPs which can develop dangerous effects to human health and the ecosystem. In addition, they are reported detected in all the environmental components including the atmosphere, water resources, soils, sediments and biota. Since the discovery of the insecticides DDT in human tissue, the fate and behavior of these type of hazardous pollutants have caught the interest of researchers. In this work, our target contaminants are polycyclic aromatic hydrocarbons (PAHs) and their methylated derivatives (Me-PAHs) and polychlorinated biphenyls (PCBs). The first part of our study investigated the contamination level of theses POPs in the different compartments of the environment (water, suspended solid matters, sediment, soil). Their occurrence and distribution were evaluated in the dissolved, particulate and sedimentary phases of the freshwater system of the Scheldt basin in the border area between France and Belgium in FRB-RegionNPC "BIOFOZI" program. An ecotoxicological risk assessment was also carried out. The same investigations were also conducted in soil samples originating from northern France and from Madagascar. The second part of the present work concern a feasibility study of PAHs-contaminated soil bio-treatment (bioremediation)

Повний текст джерелаProstate cancer (PCa) is the most frequent type of cancer in Western countries. Advanced age, ethno-geographic origin and the presence of a family history of CaP are the main clearly established risk factors. The effects of exposure to synthetic chemicals with hormonal properties, also called endocrine disruptors (EDCs), on PCa are also are suspected. The main objective of this thesis is to evaluate the relationships between plasma concentration of persistent organochlorine pollutants with hormonal properties, such as DDE (the main metabolite of DDT) and PCBs as well polymorphisms of selected genes involved in xenobiotic (GSTM1, GSTT1) and estrogens (CYP17, CYP19, CYP1B1, COMT, UGT1A1) metabolism, and the occurrence of PCa or its recurrence after treatment with radical prostatectomy. This project is based on data obtained from the population-based case-control study (KARUPROSTATE) in Guadeloupe and from cases treated by radical prostatectomy

Повний текст джерелаThe river contamination with persistent and emerging organic pollutants has raised an increasing concern about their impact on exposed ecosystems. Small Mediterranean coastal rivers have great and fast variations of hydrological flow along the year and can rapidly bring to the mediterranean sea the contamination occurring in the coastal area, especially where population density is high. The Kadicha river basin in Northern Lebanon is an illustrative example of multiple pressures encountered in the Mediterranean basin: it is a small coastal river affected by disorganized and rapid urbanization, a population growth and a chronic default of wastewater collection and treatment. In this context, various contaminants, witness of different anthropic activities were selected and analyzed within the Kadicha river basin.The main objective of this thesis was to determine the impact of anthropogenic activities on the Kadicha River watershed through the study of the contamination with persistent and emerging organic pollutants. Then, the potential environmental risk associated with their presence was assessed. Among emerging contaminants, several compounds having different physico-chemical properties were selected: personal care products (ultraviolet absorbents, musks), insecticides, biocides and surfactants (alkylphenols) and pharmaceutical products. Thus 41 hydrophobic compounds and 23 hydrophilic compounds were studied in sediments and water respectively. The environmental matrices were collected during two sampling campaigns corresponding to wet and dry seasons along sites impacted by urban, rural and mixture land uses (residential and agricultural zones).The results indicate : i) a detection of the totality of persistant organic pollutants and personal care products, insecticides, biocides and surfactants and 6 pharmaceuticals were detected, ii) a higher contamination (in terms of concentrations and diversity of molecules) in urban than in rural zones, iii) a selection of potential markers of urbanization (permethrin, galaxolide and UV-326) iv) an environmental risk for several compounds (ofloxacine (pharmaceutical), low molecular weight PAHs and polychlorinated biphenyls) was identified and v) a higher potential risk associated with the presence of persistent organic pollutants.These results can be considered a knowledge base on anthropogenic pressures and levels of contamination with persistent and emerging organic pollutants in the Kadicha river watershed. The data acquired as well as the potential environmental risks associated with the presence of certain molecules in the Kadicha river watershed lead to propose these molecules as a part of future monitoring programs for anthropized rivers in the Mediterranean basin

Повний текст джерелаThe quality of indoor environments is now a major public health concern. People spend nearly 90% of their time indoors where they are exposed to pollutants such as semi-volatile organic compounds (SVOCs) suspected of adverse health effects. Dust ingestion is a significant route of exposure to some of these SVOCs, especially for children. To characterize this exposure, it is necessary to consider the oral bioaccessibility of SVOCs, defined as the fraction of pollutant released into the gastrointestinal tract and available for absorption. In this context, the objectives of this PhD thesis are to (i) develop and validate a simple method for measuring the oral bioaccessibility of SVOCs in indoor dust and (ii) produce bioaccessibility data for SVOCs of health interest This article-based thesis consists of three chapters: a scientific context, which presents the sources and toxicity of SVOCs, then describes their presence in school air and dust, before addressing the different routes of human exposure; a state of the art on the oral bioaccessibility of SVOCs in dust; and the proposal of a simplified method for measuring this bioaccessibility, its validation, and its application to first samples. This work concludes on a broader context than ingestion by establishing perspectives that also consider inhalation and dermal bioaccessibility, in order to characterize the overall exposure to COSV in indoor environments

Повний текст джерелаThe global production of waste is increasing rapidly, posing a source of threat to living beings, human health and the environment. Most of the waste produced is disposed of in poorly controlled landfills, especially in third world countries such as Lebanon. The waste is subjected to degradation processes resulting in the release of many toxic substances mainly leachate which is loaded with pollutants constituting a major source of environmental pollution. In Lebanon, waste is disposed of in uncontrolled landfills without any prior sorting. The Tripoli landfill is one of the most dangerous landfills in Lebanon due to the disposal of leachate in the aquatic environment without any treatment.Our research work aims to study the physico-chemical characteristics; the temporal and seasonal variation in the quality of the leachate from the Tripoli landfill in northern Lebanon, and the estimation of the probable risk of leachate in the study area. In order to meet these objectives, several sampling campaigns were carried out covering the summer and winter periods, as well as the old and new cells of the body of the landfill. The variation of the 100 leachate quality parameters, namely dissolved organic components; inorganic macro-components; metallic trace elements; and xenobiotic organic compounds were monitored according to standard methods of wastewater analysis using specific laboratory equipment. Analyzes of the leachate quality showed a large variation between the two-landfill units. The content of the majority of pollutants (organic and mineral) detected in the new landfill unit is much higher than that found in the old unit. This indicates the heterogeneous state of the landfill body and the influence of age on the quality of the leachate. The quantity and quality of the leachate is strongly correlated with climatic conditions and it depends on the pollutant studied, reflecting the complexity of the seasonal effect on the quality of the leachate from the Tripoli landfill. High values of LPI (Leachate Pollution Index) and leachate pH were found which show the age of the Tripoli landfill. High values of LPI and the annual flow of pollutants (organic and mineral) were found, which shows the high toxicity of the leachate as well as the occasional pollution of the different behaviors of the neighboring aquatic environment (Abou Ali River and Mediterranean Sea).The results obtained in this study give a clear picture of the leachate quality of the Tripoli landfill; which will be used to set corrective and preventive actions for the hazardous situation of the landfill, and to attract the attention of local and national managers to limit the danger and move towards a good management of leachate rejected by the establishment of a specific treatment system of leachate

Повний текст джерелаOrganic contaminants are harmful substances present in the environment that can affect human health and ecosystems. Among them, pharmaceutical compounds and pesticides, are linked to many diseases in humans, such as cancer, respiratory disorders, and neurological disorders. They can also affect non-target species in the environment, including beneficial insects. In the case of pesticides, widely used in agriculture and other fields, alternatives are under consideration. Biopesticides, which are complex substances derived from natural sources such as plants and microorganisms, present a promising alternative to pesticides. They are presumed to be less harmful; however, the existing regulations are not well adapted to these substances, and current parameters, like DT50 and DT90, are not suitable for studying the degradation of biopesticides. Therefore, new parameters need to be developed to study the fate and impact of biopesticides. At CRIOBE research unit, a new method called Environmental Metabolic Footprinting (EMF) has been developed. This method is based on the use of non-target metabolic LC-MS in order to study the environmental fate and impact of organic contaminants and in particularly complex substances like biopesticides by analyzing the environmental matrix meta-metabolome, which includes both the endometabolome (environmental matrix metabolome) and the xenometabolome (organic contaminant compounds and their degradation products). The aim of my PhD was to bring new developments to the EMF approach in order to set up an approach for the Environmental Risk Assessment (ERA) of organic contaminants in soil and sediment environmental matrices. New parameters were set-up and additional -omics approaches were introduced. In the first chapter, I focus on determining the optimal chemical extraction method and the optimal DNA extraction kit for analyzing the fate and impact of organic contaminants in sediment matrices. Four chemical extraction methods were compared, and for DNA extraction, five commercial kits were tested. Using LC-MS results, I identified the optimal chemical extraction method, and by analyzing alpha and beta diversity metrics, the best DNA extraction kit was selected. These findings will make the EMF approach suitable and well-adapted for studying organic contaminants in sediment matrices. The second chapter centers on the development of a statistical workflow to study the fate of organic contaminants such as biopesticides (e.g., Beloukha). This workflow includes the development of a new parameter, dissipation time, which corresponds to the time required for the dissipation of organic contaminants. A 57-day kinetic experiment was conducted on a soil matrix (microcosm) and the bioherbicide Beloukha. Using ad-hoc workflow and develo pedscripts, we were able to extract biopesticide compounds from the meta-metabolome and determine the dissipation time of Beloukha. In the third chapter, I focus on the impact of Beloukha on biodiversity. Bacterial and eukaryotic metabarcoding (16S and 18S Ribosomal ribonucleic acid (rRNA) genes) were performed. The results show that biopesticide compounds significantly impacted bacteria and microeukaryotes, whereas no significant effect was observed on metazoa. Additionally, we were able to identify the specific taxa impacted and the metabolites responsible. In conclusion, this work has led to significant improvements in the EMF approach, making it more integrative and suitable for studying the fate and impact of organic contaminants in different types of matrices (soil, sediment, etc.), the introduction of genomic approach will help to determine in more details the impact of the organic contaminant on biodiversity. The new developments such as dissipation time will help update existing regulations, making them more suitable for complex substances and ensuring the safe use of biopesticides to preserve ecosystem balance

Повний текст джерелаLebanon coastal zone (LCZ) which extends over 220 km along the Eastern Mediterranean Sea is a typical case of most coastal areas of the developing countries in the Mediterranean region, where the combination of a wide range of anthropogenic activities are contributing to water pollution and environmental degradation, by the direct and indirect release of a large number of pollutants into the sea via atmospheric and river inputs. Amongst the numerous environmental concerns we are facing, the marine environment is one of the top priorities that must be addressed. Due to its ecological importance, the evaluation of coastal sediment quality constitutes an important area of research to give a clear picture of water pollution status. Much attention was paid of some priority pollutants such as persistent organic pollutant (POPs) and heavy metals as known to be toxic, persistent and bio-accumulative, carcinogenic and mutagenic. There is an urgent need to survey the levels of these pollutants in sediments due to the great lack of information in the eastern part of the Mediterranean Sea in general and particularly in Lebanese coastal zone which render our study very important and useful regionally and locally by local authority and policy makers during coastal zone management. The semi-enclosed basins such as ports and bays are very vulnerable ecosystem where build-up greatly amount of these pollutants in sediments. This why we focus on our studies of the assessment of ports sediment quality of some possible hotspots where the re-suspension and oxidation of anoxic sediment occur frequently. A special attention was taken to Tripoli harbour which is the second Port of Lebanon due to its location near some reserved island. The pollution levels of LCZ by these pollutants are assigned as moderate to high. An emergency proposal plan was prepared for Tripoli Harbour, this will assists harbour authority to response for all fire and oil spill accidents as a first step for a durable development inside this promising harbor
