Esse ambiente passou por diversos estágios de urbanização a partir 1810, sendo influenciada pela passagem dos setores produtivos do tropeirismo, erva-mate, madeireiro, agropecuário e, atualmente, atividades agroindustriais e de serviços. No entanto, a estrutura urbana teve crescimento expressivo a partir de 1970 com o ápice do êxodo rural e o aumento da população urbana. A urbanização proporcionou novos processos geomorfológicos com ações diretas e indiretamente antrópicas, produzindo novas formas e materiais que foram identificados e classificados como terrenos e depósitos tecnogênicos. Para se compreender essa dinâmica ambiental, desenvolveram-se levantamentos bibliográficos, cartográficos e de campo para se analisar as transformações ocorridas, bem como se reconstituindo historicamente os processos de uso e ocupação do perímetro urbano de 1940-2014. Foram percorridas as três subunidades de relevo: planalto de Guarapuava/Palmas; Pitanga/Ivaiporã e Foz do Areia/Ribeirão Claro, e diferentes formas: vertentes, topos colinosos e planícies. Foram descritos 30 pontos representativos de terrenos e depósitos tecnogênicos, bem como seis pontos por meio de testemunhos, com depósitos induzidos nas principais sub-bacias do ambiente urbano. Os pontos identificados e classificados correspondem em sua ampla maioria a terrenos de agradação, manifestados em depósitos de maciços isolados, lençóis de aterramento em ambientes urbanos e periurbanos. Já os terrenos de degradação correspondem às cicatrizes de aterramento e mineração, representadas pela construção da ferrovia – FERROESTE, e as cicatrizes tecnogênicas manifestadas por áreas de mineração. Quanto aos depósitos induzidos, estes correspondem aos processos de assoreamento de lagos, registrados no Parque do Lago, e aos depósitos de margem de canal das sub-bacias hidrográficas urbanas, que se formaram a partir do deflúvio gerado pela impermeabilização que arrasta os resíduos gerados (terrenos de agradação), disponíveis do processo de urbanização. Ao se observar as camadas de cada testemunho, verifica-se a ocorrência de materiais alóctones de ambiente sedimentar, tais como variação textural diferenciada de areia, silte e argila, incrustadas por plásticos, madeira, carvão, sementes e matéria orgânica. As diferentes fases de urbanização com as apropriações das diferentes formas de relevo conduzem às formações tecnogênicas, onde sua forma dependerá das características físicas do relevo, e em Guarapuava as principais manifestações ocorrem nas transições das vertentes côncavo-convexas para fundos de vale, principalmente nas planícies, e em rupturas de declive.<br>The objective of this thesis is to identify and classify the land and technogenic deposits from analyzes on changes in society about the nature occurred in the urban environment Guarapuava-PR. This place has gone through several stages of urbanization from 1810, being influenced by the passage of the productive sectors tropeirismo, yerba mate, timber, agricultural and currently agro-industrial activities and services. However, the urban structure grew significantly from 1970 to the apex of the rural exodus and the increase in urban population. Urbanization provided new geomorphological processes with direct actions and indirect anthropogenic, producing new forms and materials that have been identified and classified as technogenic land and deposits. To understand this dynamic environment, evolved bibliographic, cartographic and field to analyze the changes that have occurred, as well as historically reconstructing the use of processes and occupation of the urban perimeter of 1940-2014. The three major subunits were covered: Guarapuava / Palmas plateau; Pitanga / Ivaiporã and Foz do Areia / Ribeirao Claro, and different ways: strands, hill tops and plains. They were described 30 representative points technogenic land and deposits as well as six points through testimonies, with deposits induced in major urban environment sub-basins. Identified and classified points are in their large majority in aggradation land, manifested in deposits isolated massive, ground sheets in urban and peri-urban environments. Already the degradation of land correspond to the ground and mining scars, represented by the construction of the railway - FERROESTE, and tecnogênicas scars expressed by mining areas. As for induced deposits, they correspond to the silting process of lakes, recorded in Lake Park, and channel margin deposits of urban sub-basins, which were formed from the runoff generated by waterproofing dragging the generated waste (aggradation land), available from the urbanization process. By observing the layers of each witness verifies the occurrence of alien materials sedimentary environment, such as different texture variation sand, silt and clay, embedded in plastic, wood, coal, organic matter and seeds. The appropriation of different relief forms can lead to technogenic formations that depend on the physical characteristics of relief, and Guarapuava the main manifestations occur in the transitions of the concave-convex slopes to valley bottoms, and slope ruptures in the urban environment Guarapuava.

No. of bitstreams: 1 ELIZABETH SOARES DA SILVA.pdf: 34072737 bytes, checksum: 0c76a8b9d7dd3ed9d94348171ff7d18c (MD5) Previous issue date: 2008-06-27<br>Through productive activity, man has acted on the nature of the item has been proposed a new geological period to characterize the present time, which would be the Period Quinário or Technogene . Along with the suggestion for a new period, the term also came technogenic deposit, which features a vast amount of deposits formed as a result of human action. Can be classified as: constructed, induced and modified. This work is held to study the deposits built. More properly, identify and characterize the deposits built tecnogênicos found in the basin of Stream Anicuns in the city of Goiânia - GO and present the implications for the environment and human health. How to offer food abundant and ease of shelter, attract many insects and animals that can spread directly or indirectly many diseases, in addition to degrade the landscape, the soil and contaminate surface water and groundwater. In this study were identified nineteen deposits in the basin of Stream Anicuns, such as the results, these deposits show great diversity of debris, some may take millions of years to decompose, others have substances harmful to the soil and health. The population of Goiânia, is already realizing the impact of these deposits. The resolution of these problems hampered in the absence of educational programmes capable of involving the community and lack of public policies geared to the current urban society.<br>Através da atividade produtiva, o homem tem atuado sobre a natureza a ponto de ter sido proposto um novo período geológico para caracterizar a atualidade, que seria o Período Quinário ou Tecnógeno. Juntamente com a sugestão para um novo período, surgiu também o termo depósito tecnogênico, que caracteriza uma vasta quantidade de depósitos formados como resultado da ação humana. Podem ser classificados em: construídos, induzidos e modificados. O presente trabalho teve por objetivo estudar os depósitos construídos. Mais propriamente, identificar e caracterizar os depósitos tecnogênicos construídos encontrados na bacia do Ribeirão Anicuns no Município de Goiânia GO e apresentar as implicações para o meio ambiente e a saúde humana. Como oferece alimentação abundante e facilidade de abrigo, atrai muitos insetos e animais que podem disseminar direta ou indiretamente muitas doenças, além de degradar a paisagem, contaminar o solo e as águas superficiais e subterrâneas. Neste trabalho foram identificados dezenove depósitos na bacia do Ribeirão Anicuns, como se pode observar nos resultados obtidos, os referidos depósitos apresentam grande diversidade de detritos, alguns podem levar milhões de anos para se decompor, outros, possuem substâncias prejudiciais ao solo e a saúde. A população de Goiânia, já vem percebendo os impactos desses depósitos. O equacionamento desses problemas esbarra na falta de programas educativos capazes de envolver a comunidade e escassez de políticas públicas atuais voltadas para a sociedade urbana.

L’accroissement de l’urbanisation et le développement industriel modifient la composition des géosphères de la Terre, en augmentant le nombre de problèmes géoécologiques et en affectant négativement la santé humaine. Actuellement, plus d'attention est accordée à la surveillance de l'état des composants de l’environnement naturel urbain. En Russie, les méthodes biogéochimiques (par ex., l'application de feuilles des arbres comme un récepteur naturel de la pollution) sont largement utilisées pour caractériser les problèmes géoécologiques des territoires dans des conditions d’intensité d’activités industrielles. Dans les pays occidentaux, les méthodes permettant d'estimer l'impact des facteurs ambiants sur la géosphère et la santé humaine sont répandues, parmi lesquelles l'évaluation des impacts du cycle de vie (ÉICV). Cependant, ces méthodes ne sont toujours pas appliquées en combinaison. L’utilisation d’indicateurs efficaces reflétant l'intensité de l'impact anthropique sur les écosystèmes; d’une cartographie de la distribution des polluants, ainsi que l'utilisation a posteriori de ces résultats dans l'évaluation des impacts sur l'environnement et la prédiction de leurs effets négatifs des entreprises industrielles (toxicité humaine et l'écotoxicité) sont pertinents pour l'évaluation complète des écosystèmes urbains. Cette méthode intégrée a été proposée et mise en œuvre sur le territoire d’Ust-Kamenogorsk, l'une des villes ayant subie des transformations technogéniques significatives au Kazakhstan avec un ensemble spécifique d’entreprises<br>With widespread urbanization and industrial development, the composition of the Earth's geosphere shells has changed, increasing the number of geoecological problems of territories and negatively affecting human health. Currently, more attention is being paid to monitoring the state of the components of urban natural environments. In Russia, biogeochemical methods (e.g. applying tree leaves as a kind of natural receptor of pollution) are widely used to characterize the geoecological problems of the territories under the pressure of intensive industrial activities. In Western countries, methods allowing us to estimate the impact of ambient factors on ecosystems and human health have become widespread; life cycle impact assessment is among them. However, these methods still have not been applied in combination. Therefore, the implementation of a comprehensive assessment of urban ecosystems using indicators reflecting the intensity of anthropogenic impact on ecosystems, following mapping of pollutant distributions, as well as the subsequent use of the results in the evaluation of the industrial enterprises' impact on the environment and in the prediction of the negative effects of pollution (human toxicity and ecotoxicity) are relevant. Such integrated method combining two methodologies was suggested and implemented in the territory of Ust-Kamenogorsk city, one of the significantly technogenic transformed cities in Kazakhstan with a specific set of enterprises

<p> The digital landscape that we inhabit offers new ways of cultivating relationships. Humans are programmed to seek social acceptance and avoid social rejection. Facebook taps into this core motivation by offering variable social rewards. Habits are eventually formed that keep users coming back for more rewards. What impact does habituated Facebook use have on relationships and other criteria defined by well-being theories?</p><p> The sample for this study was 36 students who were recruited to participate in one or two phases of a sequential mixed methods study. The quantitative phase involved two surveys: the first, a validated instrument; the second, a 38-question survey created for the study to inquire about research participants&rsquo; experience using Facebook. For the qualitative phase, four students from the first phase were interviewed to further explore their experience with Facebook and well-being.</p><p> A central accomplishment of this study was the creation of a new Facebook well-being survey (FWBS). The design of this survey guided the data analysis which uncovered the key findings of this study. Results were divided into four categories of time that participants spent using Facebook per day. Half of the categories, including the largest, showed a positive correlation between well-being and the amount of time spent creating content.</p><p> Overall, participants reported that they spend significantly more time consuming (65%) than creating (35%) Facebook content. The FWBS asked participants to rank their favorite Facebook features from most to least used. Private and public messages were the most popular with Likes ranking high for the creation of content. Participants with very high well-being scores mostly used messaging features while those with very low well-being scores spent their time using other Facebook features in addition to messaging.</p><p> Emotions and relationships were the well-being components most impacted by Facebook. Sixty-five percent of participants reported they have unhealthy Facebook habits. Facebook can help with loneliness but is also a distraction, time-killer, and social-crutch. Unless Facebook is used wisely and sparingly it reduces well-being. To be a socially engaged in the Millennial Generation a Facebook account is not optional.</p>

Estas formações são cada vez mais observadas e estudadas, mesmo que com nomenclaturas diferentes de acordo com o referencial utilizado. No presente estudo, são investigadas as formações de relevos tecnogênicos na cidade de Presidente Prudente-SP, estas relacionadas ao histórico de uso e ocupação urbano e rural. As áreas elegidas para o estudo são: Conjuntos Habitacionais Jardim Humberto Salvador e Augusto de Paula; parte do Setor Leste da cidade de Presidente Prudente e Vila Nova Prudente. O objetivo geral é, portanto, a análise das transformações da paisagem através da reconstituição geomorfológica do relevo tecnogênico nas áreas de estudo. Para o cumprimento deste objetivo foram realizados procedimentos de campo, laboratoriais e de gabinete, que incluíram coleta de amostras de depósitos tecnogênicos em área de planície tecnogênica; análise granulométrica e fracionamento de areia; mapeamento das alterações ocorridas nas paisagens, especialmente das formas e feições tecnogênicas a partir da estereoscopia das fotografias aéreas de 1962, 1978, 1995 e uso de imagens atuais do Google Earth; realização da classificação dos terrenos tecnogênicos, considerando a presença de feições e formas de relevo de origem agradacionais e degradacionais. Através desses procedimentos, foi possível reconhecer que, ao longo do tempo, as feições tecnogênicas se alteraram bastante, ocorrendo, por exemplo, deposições tecnogênicas em áreas de fundos de vale cujos sedimentos são oriundos de processos erosivos instalados nos demais compartimentos do relevo (topos e vertentes) e, posteriormente, o retrabalhamento destas deposições, através da instalação de processos erosivos em áreas de planície. Com relação aos materiais manufaturados e sedimentos de origem tecnogênica, quando estudados em detalhe, possibilitaram reconhecer aspectos da tecnogênese, como o volume das deposições tecnogênicas e as possíveis áreas fontes desses materiais, como antigas áreas de deposição de resíduos sólidos domésticos. Assim, os procedimentos adotados têm se mostrado eficazes para o reconhecimento de diversas características relativas a formação e evolução de formas e deposições tecnogênicas, sendo possível a reconstituição dessas formas.<br>Technogenic deposits are a result of direct and indirect actions of society. They are able to alter the surface structure characteristics of landscapes, and consequently, the landforms and characteristics of surface materials. These formations have been increasingly observed and studied, even though the usage of different nomenclature, according to the referential utilized. At this study, it is investigated the formation of technogenic reliefs in the city of Presidente Prudente-SP, they are related to the historical usage and the urban and rural occupation. The chosen housing complex areas to be studied are: Jardim Humberto Salvador and Augusto de Paula housing Complexes; part of East Section of Presidente Prudente and Vila Nova Prudente. The general objective is the analysis of the changes in the landscape through geomorphological reconstitution of technogenic relief in these areas. In order to fulfill this objective, it was accomplished fieldwork, laboratorial and desktop procedures, which included collecting samples from technogenic deposits in area of technogenic floodplain; particle size analysis and sand fractionation; mapping the alterations which occurred in the landscapes, especially the technogenic forms and features through stereoscopy of aerial photos from 1962, 1978, 1995 and use of current images of Google Earth; classification of the technogenic grounds, considering the presence of features and forms of aggradation and degradation relief origin. Through these procedures, it was possible to recognize that as times goes by, technogenic features changes abundantly, as an example is the technogenic deposition in valley floor areas, whose sediments comes from erosive processes installed in other compartments of the relief (top and slope), and afterwards, occur the rework of these depositions, through the installing of erosive processes in plain area. Regarding the manufactured materials and technogenic sediments, when studied in detail, provide the possibility to recognize technogenic aspects, such as volume of technogenic deposition and possible source area of these materials, such as old deposition area of solid domestic waste. Thus, the adopted procedures have shown to be efficient towards recognition of the diverse characteristics concerning the formation and evolution of forms and technogenic deposition.<br>FAPESP: 2013/01302-0

L'hétérogénéité géochimique de la biosphère, due a des conditions naturelles et anthropiques différentes, est en train de changer de manière significative du fait du développement de l'homme et de la société. cependant, dans de nombreuses études, les données sur l'interaction des éléments chimiques dans ces cadres de différentes conditions écologiques locales sont absentes; peu d'attention est accordée a l'approche complexe, par exemple, l'utilisation du modèle d’évaluation des impacts sur les organismes vivants. la méthode de l'analyse du cycle de vie (acv) permet de mesurer l'ampleur et l'importance de l'impact sur l'environnement et l'organisme humain. le coefficient caractéristique (cf) - est une valeur tabulaire, proposée par le modèle, selon l'emplacement de la région. dans ce document, il est propose de modifier ce coefficient en introduisant les résultats de l'analyse biogéochimique de territoires présentant des situations écologiques différentes, afin de les classer plus précisément. cette modification détermine la pertinence de l’étude. l’objet de la recherche est déterminé par évaluation de l’état géo-écologique des zones locales de la Russie et du Kazakhstan avec l’aide des 'indicateurs de la composition élémentaire des organes et des tissus des mammifères et d'un classement de la toxicité des différents éléments a l'aide du modèle usetox. cette méthode permet d’élargir le modèle en utilisant des données locales sur la composition chimique du produit alimentaire - le porc -et ensuite peut être utilisée pour évaluer les risques sanitaires pour la population des territoires étudiés<br>The geochemical heterogeneity of the biosphere, due to different natural and anthropogenic conditions, is changing significantly as a result of the development of man and society. Modern geo-ecological studies of different territories prove the fact of close connections of living organisms with the environment. However, little attention is paid to the complex approach, for example with the use of the model of impact assessment on living organisms. The Life Cycle Assessment (LCA) method, is allowed the magnitude and significance of the impact on the environment and the human organism to be monitored. The characteristic coefficient (CF) - is a tabular value, proposed by the model, depending on the region's location. In this thesis, however, it is proposed to modify this coefficient by introducing the results of biogeochemical analysis of territories with different ecological situations, in order to rank them more precisely. It is this modification, which determines the relevance of the study. The PhD thesis is purposed to assess the geo-ecological state of local areas of Russia and Kazakhstan with the use of indicators of the elemental compositions of organs and tissues of mammals, and a ranking of the toxicity of individual elements using the USEtox model. The modification method of the USEtox impact assessment model, using the results of the chemical analysis, can be used as a local supplement in the assessment of toxic effects on the population

Technogeninės avarijos Lietuvoje – mažai ir retai nagrinėjama tema, todėl rasta mažai straipsnių ir medžiaga darbui atlikti buvo renkama iš labiausiai visuomenei prieinamų šaltinių – teisės aktų ir internetinių institucijų tinklapių. Darbe pateikta ūkinės veiklos teisinė samprata, klasifikacija, avarijos kaip visumos elementai, nagrinėtas bendras šalies ir atskirų ūkio sričių avaringumas, tirtos inspektuojančių institucijų metinės veiklos ataskaitos, ištirti technogeninių avarijų valdymo ypatumai. Darbo tikslas buvo pasiektas, nes nustatytos labiausiai pavojingos ir nepavojingos ūkinės veiklos sritys, pagal jas – objektai, įvardintos probleminės sritys ūkinės veiklos ir pavojinguose objektuose, įvardintos grėsmės ekologiniam saugumui Lietuvoje, suskaičiuotos kelerių metų avarijų tendencijos skirtingose ūkio šakose, pateiktos dažniausios technogeninių avarijų priežastys, padarytos išvados.<br>Technogenic accidents in Lithuania – a low and rarely the issue in question, therefore found few articles and material work was collected from most public soures – legislation and on the institucions website.

Coordenação de Aperfeiçoamento de Pessoal de Nível Superior<br>The changes in environmental processes results in the generation of a new geomorphological and pedological configuration consisting of materials wasted by industrial, commercial and domestic activities. Such deposits recognized as Technogenic causing innumerous social, economic, environmental problems and barriers for the urban planning. The central focus of this work in urban area of Araguaína located in the northern state of Tocantins (Brazil) lies in the improvement of the methodology of study of these artificial bodies in genesis and morphologies and in a propose of measures to mitigate the impacts and facilitate the activities of environmental planning. The methodology used was based on literature review, characterization and mapping of the study area, characterization of urban sprawl, and morphological and textural analysis of the dynamics of Technogenic Deposits. The results show great difficulty in identifying with satellite images of the DT indirectly as differentiated vegetation (exotic), emergence of new fluvial deposits, erosional features exposed by stormwater and areas with exposure of pedological layer and material handling. The DT in the city of Araguaína tends to expand its original area by entrainment of material by runoff with a layered structure and selection of tecnogenic materials in bottoms valleys. The intensity and volume of stormwater on DT added the slopes less steep causes mass movements affecting the stability of civilians building structures in several areas of the Araguaína city. Another observed fact is the amount of area with DT will become obsolete for use as public parks, green areas, as well as for the urban settlement. In this meaning, the techniques of remediation and recovery were determined according to the specific characteristics of each deposit and the environment in which it operates in the city of Araguaína.<br>As alterações dos processos ambientais resultam na geração de uma nova configuração geomorfológica e pedológica composta de materiais descartados pelas atividades industriais, comerciais e domésticas. Tais depósitos reconhecidos como Tecnogênicos causam inúmeros problemas sociais, econômicos, ambientais e causam entraves para o planejamento urbano. O foco central deste trabalho na área urbana de Araguaína situado no norte do estado de Tocantins (Brasil) reside no aprimoramento da metodologia de estudo desses corpos artificiais em sua genêse e morfologias, com vistas a proposição de medidas destinadas à mitigação dos impactos e facilitar as atividades de planejamento ambiental. A metodologia utilizada baseou-se na revisão bibliográfica, caracterização e mapeamento da área de estudo, caracterização da expansão urbana, análise morfológica e textural e análise da dinâmica dos Depósitos Tecnogênicos. Os resultados apontam grande dificuldade na identificação por imagens de satélite dos DT indiretamente como manchas diferenciadas de vegetação (exóticas), surgimento de novos depósitos fluviais, feições erosivas expostas pelas águas pluviais e áreas com exposição da camada pedológica e movimentação de material. Os DT na cidade de Araguaína tendem a expandir sua área original por carreamento do material pelo escoamento superficial com uma estruturação em camadas e seleção dos materiais tecnogênicos nos fundos de vale. A intensidade e o volume das águas pluviais sobre os DT somados a declividades menos acentuadas causam movimentos de massa afetando a estabilidade das estruturas de edificações civis em várias áreas da cidade de Araguaína. Outro fato observado é quantidade de área com DT que se tornam obsoletas para o uso público como parques, áreas verdes, bem como para o assentamento urbano. Neste sentido, as técnicas de remediação e recuperação foram determinadas em função das características específicas de cada depósito e do ambiente em que se insere na cidade de Araguaína.<br>Doutor em Geografia

This work aims to perform an environmental diagnosis in the Baixa Funda stream basin in the municipality of Araguaína-TO. The methodology used consisted of a bibliographical survey and observational field analysis with a quantitative and qualitative approach of 10 points, through geoprocessing and collection of water samples planned for the months of March and September of 2017, comprising the rainy season and the dry season. water collection at three points (P1, P7 and P10): upstream end, intermediate point of the channel and downstream end of the stream. Where laboratory physicochemical analysis was performed of the following parameters: water temperature, pH, Turbidity, total phosphorus, total nitrogen, total residue, dissolved oxygen (DO); Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD), total coliforms and thermotolerant coliforms, which were analyzed in the rainy season and in the drought period of the stream. The results showed technogenic deposits, severe environmental impact, with irregular disposal of solid wastes often in fragments, such as plastics, various metals, household waste, sewage, among others. It was concluded that the anthropic action showed to be the main active agent in the removal of the vegetation cover, in soil and subsoil contamination, being active in the acceleration of processes such as erosion, sedimentation and degradation. It is essential to assess the environmental consequences, their impacts and propose short- , medium- and long-term solutions. The data presented demonstrate that the studied area is in the process of environmental degradation, according to physicochemical evaluation, which shows the contamination of the water in the evaluated points.<br>O impacto ambiental ocorrido em uma bacia hidrográfica é responsável pela maioria dos problemas socioambientais de um município, uma vez que os recursos hídricos estão intrínsecos à urbanização. Este trabalho tem como objetivo realizar diagnóstico ambiental na bacia hidrográfica do córrego Baixa Funda no município de Araguaína- TO. A metodologia utilizada constitui em levantamento bibliográfico e análise de campo observacional com abordagem quantitativa e qualitativa de 10 pontos, através de geoprocessamento e coleta de amostras de água planejado para os meses de março e setembro de 2017, compreendendo o período chuvoso e de estiagem realizando a coleta de água em três pontos (P1, P7 e P10): extremidade montante, ponto intermediário do canal e extremidade jusante do córrego. Onde foi feito análise físicoquímica laboratorial dos seguintes parâmetros: temperatura da água, pH, Turbidez, Fósforo total, Nitrogênio total, Resíduo total, Oxigênio Dissolvido (OD); Demanda Bioquímica de Oxigênio (DBO), Demanda Química de Oxigênio (DQO), Coliformes Totais e Coliformes Termotolerantes, estes em análise no período chuvoso e no período de estiagem do córrego. Os resultados apresentados constataram depósitos tecnogênicos, impacto ambientais graves, com disposição irregular de resíduos sólidos frequentemente em fragmentos, como plásticos, metais diversos, lixo doméstico, esgoto, dentre outros. Conclui-se que a ação antrópica se mostrou como sendo o principal vetor atuante na remoção da cobertura vegetal, na contaminação do solo e subsolo, sendo atuante na aceleração de processos como: erosões, assoreamentos e degradação. É fundamental avaliar as consequências ambientais, seus impactos e propor soluções a curto, médio e longo prazo. Os dados apresentados demonstram que a área estudada se encontra em processo de degradação ambiental, conforme avaliação físico-química, que mostra a contaminação da água nos pontos avaliados.

Disertacijoje nagrinėjama technogeninės taršos pažeistų skirtingų miško ekosistemos komponentų (medyno, dirvožemio, krūmokšnių, žolinių augalų ir samanų danga) pokyčiai sumažėjus gamyklos AB „Achema“ taršai. Naudojant 26 metų (1981–2007) ir dabartinių metų (2011–2012) tyrimų duomenis yra atlikta analizė apie skirtingus miško ekosistemos komponentų pokyčius ir įvertinta miško ekosistemų atsikūrimo galimybės. Remiantis tyrimų rezultatais nustatyta, kad praėjus 10–20 metų laikotarpiui nuo gamyklos teršimo pradžios (1979 m.) gali atskurti pažeistos miško ekosistemos. Pirmiausia atsikuria pažeisti medynai, po to – dirvožemio cheminės ir biologinės savybės, vėliausiai – krūmokšnių, žolinių augalų bei samanų danga ir dabartinė ekosistemų būklė yra artima neužterštiems žaliašiliams. Tačiau arčiausiai gamyklos krūmokšnių, žolinių augalų ir samanų dangoje vis dar randami nitrofiliniai augalai, kurie nebūdingi neužterštiems žaliašiliams. Tai rodo, kad dėl medyno struktūros negrįžtamumo prie AB „Achema“ krūmokšnių, žolinių augalų ir samanų danga išlieka pakitusi.<br>Doctoral dissertation presents the restoration of various components of forest ecosystem (stand, soil, the cover of brush, herbaceous vegetation and mosses) after the reduction of air pollution from the plant of fertilizers Achema. Using study data of 26 years (1981–2007) and of the current year (2011-2012), an analysis of the changes of different components of forest ecosystems has been carried out and recovery possibilities of forest ecosystems were evaluated. Based on the survey results it was found that after 10–20 years since the beginning of pollution from the factory (1979) damaged forest ecosystems are able to recover. First of all recover damaged stands, then – chemical and biological soil properties, at the latest – the cover of shrubs, herbaceous plants and mosses, and the current state of forest ecosystems is similar to control pine stands. However, ground vegetation in the nearest to the factory sites still contains nitrophilous plants which are not typical for uncontaminated pine forests. This shows that due to the irreversibility of the structure of stands near Achema, the cover of shrubs, herbaceous plants and mosses remains altered.

Les sédiments fins qui s’accumulent naturellement en amont des ouvrages hydroélectriques sont parfois amenées à être gérés à terre, pour des raisons techniques ou environnementales. L’une des voies de valorisation envisagée pour les gérer est la construction de sols fertiles pour l’aménagement d’espaces végétalisés ou encore pour la réhabilitation de zones dégradées. Cet usage des sédiments en tant que matériaux alternatifs pour construire des sols contribue à préserver la ressource en terre végétale et nécessite de prouver la valeur agronomique et l’innocuité environnementale des sédiments. Une approche expérimentale (essai sous serre de 3 mois et essai in situ en bacs lysimétriques de 24 mois) a permis d’évaluer les composantes physiques, chimiques et biologiques de la fertilité de sols construits à partir de 6 sédiments, seuls ou mélangés avec 40 % (v:v) de compost de déchets verts.Les résultats de l’étude ont mis en évidence que la capacité d’agrégation des sédiments est un facteur clé de leur fertilité. Le suivi du développement de la couverture végétale des sols construits a démontré la capacité de tous les sédiments étudiés à être support de végétation. Les sédiments riches en matière organique (MO) (&gt;30 g kg-1) sont adaptés aux végétaux des espaces végétalisés ayant potentiellement des exigences hydriques et trophiques élevées. Les sédiments pauvres en MO (&lt;30 g kg-1), semblent davantage adaptés à une utilisation pour des opérations de restauration où les exigences des végétaux sont généralement moindres. Ce travail aboutit à la proposition de critères environneme<br>Fine sediments naturally accumulate upstream of hydropower facilities. For technical or environmental reasons, they occasionally have to be dredged and land managed. Using dredged sediment to construct fertile soils and set up green spaces or rehabilitate degraded land is one the ways dredged sediment can be valorized. This use of sediment as an alternative soil-building material helps preserve the topsoil resource, but its agronomical value and environmental safety first has to be demonstrated. We used an experimental approach (a 3-month greenhouse trial and a 24-month in situ lysimeter test) to assess the physical, chemical, and biological parameters of soil fertility from 6 sediments that were either pure or mixed with 40 % (v:v) of green waste compost.The results showed that sediment aggregation capacity is a key factor of their fertility. The monitoring of vegetation cover development on the constructed soil demonstrated that all six sediments could support vegetation. High organic matter (OM) content sediments (&gt; 30 g kg-1) are suitable to grow plants with potentially high water and nutrient requirements. Low OM content sediments (&lt; 30 g kg-1) appear to be more suitable for use in restoration operations where plant requirements are generally lower. This work leads to the proposal of environmental and agronomical criteria for directing sediments towards soil construction and propose adapted uses
