Full textThis thesis deals with the behavior of a priority compound on the basis of the framework Directive on water at European level: tributyltin (TBT) ) and its metabolites (dibutyltin (DBT) and monobutyltin (MBT)). The study is focused on two waste stabilization pond treatment plants (WSP), which is an appropriate treatment to domestic effluents from sparsely urbanized areas.This thesis comes to fill the lack of scientific results on (1) the level of butyltin concentrations in domestic effluents from sparsely urbanized areas, in the input of the WSP and the output after treatment; (2) the efficiency of butyltins elimination by the WSP treatment; (3) the identification of the processes that control the fate of these elements during the treatment.Butyltins are measured in particulate and dissolved matrices and in sludge, by GC-ICP-MS, in all stages of the treatment by lagooning of two villages of the Department of Hérault (34, France): Gigean (6000 p.e.) and Montbazin (4500 p.e.).It is shown that the three butyltin species are consistently present in all samples taken from the two WSP. Butyltins arrive primarily in particulate form in the raw water. During treatment, the processes of sorption onto particulate matter and the settling of the latter at the bottom of each basin are the main factors for the elimination of butyltins. The first anaerobic ponds, characterized by deep depth and long residence times, allow the elimination of more than 60% Gigean (93% at Montbazin) of butyltins. Bottom sludge of each basin show high butyltins concentrations. The resuspension of butyltins is noted in the last maturation ponds, characterized by shallow depth, which may be due to re-thermal stratification. At the outlet, despite significant butyltin removal, concentrations in butyltins remain high (12 to 228 and 1.8 to 15 ng (Sn). L-1, respectively for Montbazin and Gigean).Laboratory batch experiments were conducted to study sorption processes following several experimental protocols. It was thus shown that: (1) the distribution of the butyltin species between solid and liquid phases is different from one test to another according to the operating conditions; (2) the affinity between butyltins and bottom sludge is important, regardless of its provenance. 98% of the butyltins are found in the solid phase, due to their hydrophobicity. The TBT sludge-water partition coefficient is higher than that obtained for other type of solid phases (75000 L.kg-1); (3) the process of sorption is fast.Moreover processes of sorption, desorption and dealkylation of TBT, explaining changes in concentrations of MBT and DBT in the solid phase were identified. Desorption of TBT is fast. It degrades in the liquid phase in DBT which part turns into MBT. The sorption of MBT on sludge has been systematically measured. Therefore, the sorption phenomenon is not completely reversible over time. These results help to explain the dysfunctions observed in WSP, for example after direct inputs of rainwater.This thesis shows the systematic presence of butyltin in waste stabilization pond treatment plants. In-situ data coupled with laboratory tests allow to understand the behaviour of these compounds during this treatment: the solid fraction plays a key role in the processes of sorption-desorption-(bio) degradation of butyltins

Full textDredging sediments are an abundant and stand for a strategic alternative mineral granular resource in construction. This PhD work specifically focuses on the Grand Port Maritime de Dunkerque (GPMD) dredging sediments, resulting from an active lagooning. The research objective is to evaluate the potential for recovery of these sediments coming directly from the GPMD lagoon basins (partly dehydrated but poorly moist) in the formulation of self-consolidating concretes (SCC), without any additional treatment before their incorporation into the cementitious materials (without drying, nor calcination in particular).Three GPMD dredging sediments were selected for the study, their difference being their fines content at 63 μm, respectively of the order of 34, 43 and 49%. Because of their high percentage of particles smaller than 125 μm and their particle size distribution, the interest of the study also lies in the assessment of the ability of sediments to substitute the natural mineral fillers conventionally used in the composition of SCC.A specific experimental protocol is developed to overcome the problem of presence of sediment agglomerates in cementitious matrices. The overall experimental formulation methodology is based on the Densified Mixture Design Algorithm (DMDA) method for the determination of SCC compositions, the AFREM method and the equivalent paste method. On the set of formulations carried out, the physical-chemical, rheological, mechanical and environmental performances as well as a first approch of the durability with regard to freeze-thaw are studies. The influences of sediment fines on mechanical performance and freeze / thaw resistance are more nuanced, although the overall performance of the matrices is proven. From an environmental point of view, the developed SCCs are classified as inert materials

Full textLes effluents liquides de la production animale peuvent polluer le sol, l'eau et l'air. La station Expérimental de Guernevez utilise un système intègré pour réduire les pollutions et améliorer le recyclage de l'eau et des nutriments. Il associe à une porcherie avec rinçage des déjections par chasse d'eau, un tamis, un lombrifiltre, des lagunes et des marais filtrants. Nos résultats montrent l'effet du recyclage sur la stoechiométrie des éléments chimiques du liquide. Les émissions de gaz du lombrifiltre sont minimisées quand la population lombricienne est maximisée. Le puit de méthane par le lombrifiltre a été confirmé. Ces résultats indiquent que l'abondance de vers de terre peut être employée comme bio indicateur de faibles émissions dans les systèmes de transformation des effluents. L'évolution des éléments chimiques aux chaque partie du système indique que la stoechiométrie des nutriments devrait changer dans les milieux agricoles et probablement dans les productions où l'efficacité du recyclage est augmentée

Full textThe purpose of this work was to evaluate the impact of a landfill on groundwater quality.Municipal solid waste from the Etueffont landfill (Belfort area, France) was mechanically andbiologically treated (shredding and aerobic composting) before being disposed of in an unlinedarea and in a lined cell. The leachate characterization performed over a 21-Year period (1989-2010) showed a rapid degradation of waste. A steady state was reached at the end of themonitoring. Waste pretreatment enhanced the rate of biodegradation and reduced the pollutionpotential of the landfill. The leachate produced was treated on site in a natural lagooning. Whilelagooning is not a widespread practice for leachate treatment, significant removal (75-90 %) oforganic matter, suspended solids, nitrogen and phosphorus was observed. In previous studies,groundwater contamination was highlighted around the landfill. As a consequence, geophysicalinvestigations of the area by electrical resistivity tomography and physico-Chemical analyses wereconducted in order to delineate the contamination plume. The results showed leachate infiltrationinto the soil below the unlined part of the landfill and leakage through the watertightgeomembrane of the lined cell. Seepage of wastewater into the soil below the lagoons was alsoobserved. The extent of contamination plume was limited and was mostly limited to the landfillboundaries. The results of this work allowed to determine the location of the contaminated areasand helped to choose the appropriate physico-Chemical analytes of the post-Closure groundwatermonitoring program, which will be applied to the landfill until the end of 2031

Full textThe Bizerte Lagoon watershed is surrounded by intense agricultural activities. The use of phytosanitary products to treat the crops that surround this watershed, causes a deterioration of the lagoon water quality. Monitoring the level of pollution in this ecosystem requires the application of combined approaches. Thus, in this work a survey is carried out to determine the sources of pollution due to agricultural activities and to identify pesticides used by farmers. To verify the presence of the molecules determined during the investigation, a diagnosis of water column pollution is carried out using two sampling techniques: grap sampling and passive sampling (POCIS). Sediments are also threatened by these xenobiotics, thus, a screening was carried out in this matrix. It is relevant to determine the fate of these pollutants once they are present in the aquatic environment. Thus, the study of their photodegradation in the water column was carried out. The degradation of these pollutants can give rise to by-products that are more toxic than the parent molecules. An ecotoxicological approach is developed in this work to determine the toxicity of these products on a model species Ostreococcus tauri

A pesquisa refere-se à paisagem do município de Laguna e suas relações com o ser humano, no tempo e no espaço: a cultura, a memória, o meio físico, o patrimônio cultural e natural, as transformações ocorridas e a necessidade de sua preservação. O patrimônio natural e cultural do município de Laguna tem características litorâneas, expressas pela fauna, flora, praias, promontórios, dunas, restingas, lagoas, sítios arqueológicos, comunidades pesqueiras tradicionais, pequenas propriedades rurais e aglomerados urbanos. Neste contexto, as paisagens culturais e naturais, além das transformações espontâneas, enfrentam processos de descaracterização relacionados às atividades humanas, com uso e ocupação do solo, que refletindo os sucessivos ciclos econômicos, agravaram-se na última década pelo crescente processo de urbanização da costa, devido à segunda residência e ao turismo sazonal, sem uma contrapartida adequada de infra-estrutura. Com este trabalho pretende-se introduzir objetivos de proteção ao patrimônio cultural e natural da paisagem na elaboração de diretrizes de política urbana para o município de Laguna. Para tanto, adotou-se como base conceitual e metodológica o método do Catálogo de Paisagem da Cataluña na Espanha apropriada à organização e gestão da paisagem, à perspectiva de planejamento territorial e à integração da paisagem em políticas urbanísticas: de infraestrutura, agrícola, cultural, ambiental, social e econômica. Com base nos dados levantados, seis unidades de paisagem foram identificadas e caracterizadas, permitindo avaliar a paisagem natural e cultural, urbana e rural, reconhecendo valores e dinâmicas próprias. Na busca da definição dos objetivos de qualidade paisagística foram estabelecidas diretrizes, medidas e propostas de atuação necessárias para gestão e proteção da paisagem natural e cultural de Laguna.
This study refers to the landscape of Laguna, State of Santa Catarina and the relationship between nature and humans through time and space, including the culture, memory, physical environment, cultural and natural heritage, changes, and the need for its preservation. The natural and cultural heritage of Laguna has coastal characteristics, expressed by the fauna, flora, beaches, headlands, dunes, reefs, lagoons, archaeological sites, traditional fishing communities, small rural farms and urban areas. In this context, cultural and natural landscapes face disfigurement due to human activities, soil use and occupation, which reflects the successive economic cycles. This process has worsened in the last decade because of the increasing coastal urbanization, due to the seasonal tourism and second homes, without appropriate infrastructure. This study is intended to set goals for cultural heritage and natural landscape protection by developing guidelines for the urban policy of Laguna. For that purpose, the proposal of Landscape Catalogue of Catalonia, Spain was adopted as the conceptual and methodological basis for the appropriate landscape organization and management, the perspective of territorial planning and the integration of landscape in urban policies, encompassing infrastructure and agricultural, cultural, environmental, social and economic components. Based on data collected, six landscape units were identified and characterized, allowing evaluation of the natural, cultural, urban and rural landscape and recognizing their own dynamics and values. In setting goals for landscape quality, guidelines, measures and proposals for action were established to improve the natural and cultural landscape management and protection of Laguna.

O presente trabalho analisa a dinâmica urbana nos Balneários da praia do Laranjal a partir das formas de ocupação e uso do solo, tomando a paisagem como elemento essencial para a identificação dos conflitos socioambientais latentes e evidentes, bem como o território na identificação dos atores sociais e suas relações político-econômicas e culturais. O espaço, por sua vez é definido como um produto histórico e social, condicionado pela sociedade, conforme os interesses, as necessidades, a cultura, entre outros. O trabalho revela como a sociedade pelotense se relaciona com a sua orla lagunar, ou seja, de um lado orientada pelas necessidades e condicionantes socioculturais e econômicas de grupos que usam o espaço para lazer e moradia e, de outro, uma relação orientada pelos interesses capitalistas que incorporaram os balneários Santo Antônio e Valverde, bem como o entorno de suas vias de acesso à (re) produção do espaço geográfico. Suas paisagens naturais tornaram-se condição necessária à reprodução do papel que a orla lagunar desempenha na divisão espacial do trabalho da cidade de Pelotas: o de zona de veraneio, espaço de lazer dos finais de semana e de expansão urbana voltada à classe média-alta. Os conflitos socioambientais aparecem ao mesmo tempo como produto do urbano e condição para a sua reprodução. Por fim, o trabalho sugere a possibilidade de inclusão do município no Projeto Orla, como subsídio para uma gestão integrada dos conflitos socioambientais identificados ao longo do mesmo.
Abstract : The present paper analyzes the Laranjal Beach resort urban dynamics based on its settlement and land use, considering both landscape and territory as essential items for the identification of latent as well as apparent socio-environmental conflicts of social actors and their political, economic and cultural relations. Space has thus been defined as a historical and social product conditioned by society such as interests, necessities and culture, among others. The paper shows how the Pelotas City society relates to its lagoon shore - on the one hand guided by the necessities as well as cultural and economic statuses of the human groups who use that space for leisure and dwelling, and on the other hand guided by capitalist interests that encompass both Santo Antonio and Valverde Beach resorts and access road surroundings for geographical space (re) production. Its natural scape is the sine qua non condition for the reproduction of the role that the lagoon shore plays in the spatial labor division of the city of Pelotas as a summer resort area, a recreational space on weekends, and an upper-middle class oriented urban sprawl. Socio-environmental conflicts arise simultaneously as urban products and as a requirement for their reproduction. Finally, the paper focuses on the possibility of including the city of Pelotas in the 'Projeto Orla' (Shore Project) as a subsidy for an integrated management of the socio-environmental problems that have been identified.

Full textO objetivo do trabalho é descrever e analisar a transformação do porto de Laguna em terminal pesqueiro regional e a sua relação com as atividades pesqueiras locais. O desafio da pesquisa esteve em buscar uma reconstituição da história econômica do porto e da cidade a partir das múltiplas determinações contidas na construção da realidade. O porto de Laguna passou por diversas fases, sendo, primeiramente, o porto das conquistas no Brasil meridional; depois, o porto da colonização do sul de Santa Catarina; porto carvoeiro; e, por último porto pesqueiro regional. A consolidação do novo padrão de acumulação regional com base na expansão do complexo carbonífero catarinense resultou no abandono do porto de Laguna, que foi substituído pelo de Imbituba, acelerando o processo de desintegração comercial e produtiva da cidade. A constituição do porto pesqueiro de Laguna, a partir de sua oficialização pelo Decreto-Lei nº 525, de 8 de abril de 1969, se tornou a nova esperança para o desenvolvimento da economia local. A abordagem metodológica foi realizada por meio de pesquisas bibliográficas e documentais, orientada pela técnica qualitativa associada ao estudo de caso. A longa trajetória do porto de Laguna e a especialização recente em terminal pesqueiro estiveram ligadas ao baixo padrão de acumulação da economia local e a processos de integração e desintegração produtiva com a região sul catarinense e o restante do País. A construção desse porto pesqueiro é resultado de políticas públicas destinadas ao processo de modernização da pesca nacional e catarinense. Contudo, a crise da acumulação pesqueira, em meados da década 1970, interrompeu as obras no porto. Referidas obras foram inauguradas apenas no início dos anos de 1980, mas isso não foi suficiente para dinamizar a pesca industrial local. Com a extinção da SUDEPE (Superintendência do Desenvolvimento da Pesca), em 1989, e da PORTOBRÁS (Empresa de Portos do Brasil S.A.), em 1990, a administração do porto pesqueiro de Laguna foi transferida, em 1991, para a CODESP (Companhia Docas do Estado de São Paulo), o que representou a falta de investimento e a paralisação de suas atividades. A partir de 2000, com o advento das novas políticas desenvolvimentistas para o setor, as obras de manutenção e de melhoramento no porto foram retomadas e a produção da indústria local ganhou um novo impulso. Dessa forma, considera-se que a implantação da estrutura do porto pesqueiro não foi suficiente para transformar o baixo padrão de desenvolvimento local. A constituição recente da indústria da pesca de Laguna, nesse caso, pode ser vista a partir da retomada das políticas públicas para o porto e para setor pesqueiro.
