A hierarchical and standardized environmental disturbance index, specifically designed for karst landscapes, was created by van Beynen and Townsend (2005). To assess the applicability of the index and provide recommendations for its refinement, the index was applied in four west-central Florida counties and interviews were conducted with local and state officials, community planners, and land resource managers. The karst disturbance index consists of 30 indicators contained within five broad categories: geomorphology, hydrology, atmosphere, biota, and culture. Data was readily available for most environmental indicators used to construct the index. Overall, levels of disturbance vary between the counties due to the level of urbanization, with the highly populated Hillsborough and Pinellas Counties having higher degrees of disturbance than less developed Pasco and Hernando Counties. While this result may seem obvious, the measure of disturbance using many indicators provides benchmarks of levels of disturbance that can be reassessed with time and highlights those aspects of the environment most in need of attention. Several minor issues arose during the testing: the need for broader indicator descriptions that encompass a variety of scenarios, a new water quality indicator, obsolete sinkhole data, and a lack of data for biota indicators. The lack of data for certain indicators suggests where future research efforts can be directed.

Recent studies of the environmental Kuznets curve raise questions regarding the relationship between environmental indicators and GDP and the fundamental reasons that explain this relationship. In response, this thesis presents one-sector and two-sector models to analyze the alternative causal relationships between an environmental indicator and GDP at different stages of economic development. These models analyze how economic scale, technology, preferences, and economic structure influence the causality and shape of the relationship. These theoretical studies are followed by two empirical studies. The first tests the causal relationship between CO2 emissions and GDP in Canadian manufacturing industries. The second explores several factors as the fundamental causes that influence the CO2 emissions in the same industries. Factors, such as economic scale, preferences, technological progress, structural change, and energy input, are found to be crucial in the determination of CO2 emissions. The empirical results are positive, but there are data limitations. The empirical studies can be re-evaluated as more data becomes available.

Recent advances in nanotechnology have led to the production of materials with nanoscale dimensions (nm) and properties distinctly different from their bulk (>100 nm) counterparts. With increased use, it is inevitable that nanomaterials will accumulate in the environment and there is concern that the novel properties of nanomaterials could result in detrimental environmental and human health effects. In particular, there has been concern recently regarding the use of silver (Ag) based nanomaterials as antimicrobial agents in consumer and medical products. Current regulations dealing with the discharge of metals into the environment are based on total concentrations with no consideration for the form (e.g., ionic, nanoparticle, colloid) which can largely determine toxicity. Methods for the identification and characterization of nanoparticulates within complex matrices are lacking and the development of robust methods for this purpose are considered a high priority research area. This research focuses on the development and application of a novel method for characterizing Ag manufactured nanoparticles (MNPs) within terrestrial environments, in particular in soil pore water, with applications relevant to other metal MNPs as well. The method was then applied to understand the dynamics and behavior of Ag MNPs in soil and soil amended with sewage sludge biosolids.

Non-point pollution from stormwater runoff is one of the greatest threats to water quality in the United States today, particularly in urban karst settings. In these settings, the use of karst features and injection wells for stormwater management results in virtually untreated water being directed into the karst aquifer. Currently, no policies exist specifically to provide water quality protections to karst environments. This study utilized a combination of karst stormwater quality data, along with survey data collected from MS4 Phase II communities, and an analysis of current federal, local, and state water quality regulations, to assess the need for karst-specific water quality regulations. Water quality data indicate that significant levels of contamination are mobilized during storm events, and often are directed into the karst system via Class V injection wells. Survey data collected from MS4 stakeholders in the karst regions of Kentucky indicate stakeholders are generally unable to explain local karst regulations or the steps taken to develop them. This confusion comes in part from insufficient progress on evaluation criteria available for the MS4 Minimum Control Measures (MCMs). Karst waters are often placed into the legal “gray zone” due in part to differences in definitions of key terms in state and federal regulations. This study recommends the development of regulations specific to karst waters at the state and federal levels through either the adaptation of existing or creation of new policies, which place an emphasis on the integration of water quality monitoring and karst education.

Therefore, restoration of riparian forests has been recommended as the best strategy for the recovery of streams in watersheds deforested by land use and cover. In Brazil, projects of riparian forest restoration are still recent and little is known about their effects on adjacent streams ecosystems. This study evaluated the effects of riparian forest restoration on stream water quality and aquatic macroinvertebrate communities using the multiple spatial scales approach. Sampling was carried out using the field protocol developed by the Environmental Protection Agency of the United States of America (US-EPA). We compared streams with natural riparian forests, streams with riparian forests in restoration and streams with riparian zones covered by pasture or grasses. A 150m reach was defined in each stream, and measurements of the physical structure of habitats and water quality were made, as well as samples of aquatic macroinvertebrates. Land-use and cover of each stream sub-basin was carried out through an environmental characterization of the landscape. Riparian forest restoration did not affect stream water quality and biological diversity after 10 and 13 years of project implementation, suggesting that the recovery of tropical streams in response to riparian forest restoration may be slow in sub-basin heavily altered by human activities. The present study fills a knowledge gap on the effects of riparian restoration and suggests the need for further studies and long term evaluations integrating new riparian forest restoration projects in watersheds with different intensities of human degradation to better understand the effects of the implementation of these projects on the quality of stream water and aquatic communities. / A conversão de áreas naturais para as atividades humanas nas bacias hidrográficas é a principal causa da degradação de florestas ripárias, o que, consequentemente, diminui a integridade dos ecossistemas aquáticos. Assim a restauração de florestas ripárias tem sido recomendada como a melhor estratégia visando à recuperação de riachos em bacias desmatadas pelo uso e ocupação do solo. No Brasil, projetos de restauração de florestas ripárias ainda são recentes e pouco se conhece sobre os seus efeitos nos ecossistemas de riachos adjacentes. Este estudo avaliou os efeitos de florestas ripárias em restauração na qualidade da água e nas comunidades de macroinvertebrados aquáticos de riachos, utilizando a abordagem de múltiplas escalas espaciais de investigação. Para a amostragem, foi utilizado o protocolo desenvolvido pela Agência de Proteção Ambiental Norte-Americana (US-EPA). Foram comparados riachos com floresta ripária natural, floresta ripária em restauração e com zonas ripárias alteradas por pastagem ou gramíneas. Um trecho de 150 m foi definido em cada riacho e em cada trecho foram realizadas medidas da estrutura física dos habitats e da qualidade da água e amostragens de macroinvertebrados aquáticos. Na microbacia de cada riacho foi realizada a caracterização ambiental da paisagem para analisar o uso e ocupação do solo. A floresta ripária em restauração após 10 e 13 anos de implantação não afetou a qualidade da água e a diversidade biológica, sugerindo que a recuperação de riachos tropicais em resposta à restauração de florestas ripárias pode ser lenta em bacias hidrográficas fortemente alteradas pelas atividades humanas. O presente estudo preenche uma lacuna de conhecimento sobre os efeitos de florestas ripárias em restauração em riachos de paisagens rurais e sugere a necessidade de mais estudos e avaliações em longo prazo, integrando novos projetos de restauração de floresta ripária em bacias hidrográficas com diferentes intensidades vii de degradação humana, para melhor se compreender os efeitos da implantação destes projetos na qualidade da água e comunidades aquáticas. / FAPESP: 2013/19950-9

Knowing the importance of an active, participatory and permanent surveillance involving community participation for the success of prevention and harm reduction the present study aimed to evaluate the knowledge of the vector of Chagas disease living in rural communities with a history of triatomine capture the city of Natal, Rio Grande do Norte - Brazil, and to verify the presence and association of environmental indicators of risk for infestation of insects in these communities. For this, we used a semi-structured questionnaire administered to the resident responsible for the residence containing questions about their socioeconomic profile and also issues related to the vector of Chagas disease. For assessment of environmental risk indicators, we used a structured interview. It was observed lack of knowledge of the residents on issues related to the life cycle of the insects and on the time of day and the time of year when more appear and how are born. In addition, lack of guidance was detected in the population as to what action to take when a vector is found at his residence. It was an observed association between socioeconomic profile and knowledge of residents about the triatomine. In 10.75% of the homes visited were captured triatomine and association was observed between the catch and the presence of risk factors for the presence of these insects. Among the indicators are present the structure of households, peridomicile characteristics and the presence of wild animals (p<0.05). In this study, it is evident the need for greater disclosure of information related to the vector of the disease, in order to prevent its spread in the studied areas. The observed association between the capture of insects and the presence of environmental risk indicators in the communities emphasize the importance of early identification of these factors in order to improve prevention and control / Devido a sua prevalência e a gravidade de suas manifestações a doença de Chagas consiste, ainda hoje, um grave problema de saúde pública nos países afetados. Sabendo-se da importância de uma vigilância epidemiológica atuante, participativa e permanente envolvendo a participação da comunidade para o sucesso da prevenção e redução do agravo a presente pesquisa objetivou avaliar o conhecimento sobre o vetor da doença de Chagas de moradores de comunidades rurais com histórico de captura de triatomíneos no município de Mossoró, Rio Grande do Norte, além de verificar a presença e associação de indicadores ambientais de risco para infestação de triatomíneos, nessas comunidades. Para isso utilizou-se um questionário semiestruturado aplicado ao morador responsável pela residência contendo perguntas sobre seu perfil socioeconômico e também questões relacionadas ao vetor da doença de Chagas. Para avaliação dos indicadores ambientais de risco foi utilizado um roteiro estruturado.. Foi observada falta de conhecimento dos moradores sobre questões relacionadas ao ciclo biológico dos triatomíneos, assim como sobre o horário do dia e o período do ano em que mais aparecem e como nascem. Além disso, foi detectada falta de orientação para a população a respeito de que atitude tomar quando um vetor é encontrado em sua residência. Foi observada associação entre o perfil socioeconômico e os conhecimentos dos moradores sobre os triatomíneos. Em 10,75 % das casas visitadas foram capturados triatomíneos e foi observada associação entre a captura e a presença de indicadores de risco para a presença desses insetos. Dentre os indicadores presentes estão à estrutura das residências, características do peridomicílio e presença de animais silvestres (p < 0,05). Com esse estudo, torna-se evidente a necessidade de maior divulgação sobre informações relacionadas ao vetor da doença, a fim de se evitar a sua disseminação nas áreas estudadas. A associação observada entre a captura de triatomíneos e a presença de indicadores ambientais de risco nas comunidades ressalta-se a importância da identificação prévia desses fatores com o objetivo de melhorar as ações de prevenção e controle / 2017-01-30

Dentre os setores que se apresentam no rol das indústrias com alta geração de resíduos sólidos, efluentes líquidos e emissão gasosas em suas operações produtivas está a indústria frigorífica de bovinos. Maior exportadora mundial de carne bovina, esta indústria tem o desafio de: i) produzir alimentos com garantia de qualidade e segurança microbiana; e ii) garantir que o processo produtivo seja inovador a ponto de proporcionar sustentabilidade e diminuição dos impactos ambientais. Frente a este contexto, este trabalho objetivou elaborar um constructo metodológico quantitativo para auxiliar as empresas pertencentes à indústria frigorífica de bovinos a avaliarem seu desempenho ambiental de forma ampla. Trata-se de um trabalho quantitativo subdividido em três etapas metodológicas sendo: aprofundamento da teoria de Avaliação de Desempenho Ambiental, mapeamento do processo produtivo de bovinos, e elaboração do constructo metodológico. Como resultado criou-se um constructo que contempla 31 indicadores agrupados em 6 aspectos, poderados a partir do método AHP (Analytic Hierarchy Process), mensurados através de escalas de avaliação específicas. A título de exemplificação, o constructo foi aplicado em duas empresas do setor. / The environmental impacts caused by productive operations have been increasingly discussed in the most diverse social spheres. Among the sectors that appear in the list of industries with high generation of solid waste, liquid effluents and gaseous emissions in their productive operations is the cattle industry. As the world's largest exporter of beef, this industry has the challenge of: i) producing food with quality assurance and microbial safety; and ii) ensure that the production process is innovative to the point of providing sustainability and reducing environmental impacts. Thus, this study aimed to elaborate a quantitative methodological construct to help beef industry companies to evaluate their environmental performance in a broad way. It is a quantitative study subdivided into three methodological stages: deepening of the theory of Environmental Performance Evaluation, mapping of the productive process of beef, and elaboration of the methodological construct. As a result, the study has created a construct that contemplates 31 indicators grouped in six aspects, weighted by the AHP (Analytic Hierarchy Process) method, measured through specific evaluation scales. As an example, the study applied the construct to two companies in the sector.

Para o enfrentamento dos problemas socioambientais contemporâneos emergentes, é essencial o desenvolvimento da educação ambiental na formação dos sujeitos para a cidadania e a potencialização de ações reflexivas, críticas e participativas. Neste contexto, um dos principais espaços para que isso ocorra é a escola, a qual está desafiada a educar para a sustentabilidade socioambiental e a constituir-se em um espaço educador sustentável. No entanto, surgem dúvidas por onde começar e os caminhos a percorrer, por isso a necessidade de desenvolver instrumentos de avaliação. Esta pesquisa teve por objetivo analisar o processo de construção participativa de uma matriz de indicadores de educação ambiental para avaliar a dimensão ambiental das escolas. O campo empírico da pesquisa foram nove escolas públicas estaduais localizadas no município de Curitiba-PR. Os sujeitos da pesquisa foram oitenta e quatro participantes, sendo professores, funcionários, alunos (maiores de 14 anos), equipe pedagógica e diretiva. Como metodologia optou-se pela abordagem qualitativa, tendo em vista as características do objeto e dos objetivos. Para a coleta de dados foram utilizadas a pesquisa documental e bibliográfica, bem como, técnicas de metodologias participativas. A pesquisa se delineou em duas fases, sendo a primeira para a construção coletiva da matriz de indicadores desenvolvida em uma escola colaboradora e a segunda fase para aplicação e validação da matriz construída, realizada em oito escolas. A análise do processo subsidiou o aperfeiçoamento da matriz, que possui três dimensões da educação ambiental: Gestão, Currículo e Espaço Físico, contemplando dez indicadores e cinquenta questões descritoras.

In agriculture are diverse, and the intensive use of land and inappropriate agricultural practices causes negative effect on the environment besides affecting crop productivity and quality of life of man. So this study was objective to analyze parameters indicators of environmental impacts in the Cruzeta the Discrict Irrigation. During the period July 2007 to March 2008 samples were collected in lot 01 and 02 of the irrigation district. The monitoring was conducted in four sampling points, three (3) located in the irrigation channels and 1 (one) located in a cacimb?o. Were monitored pH, CE, STD, SS, NO3-, OD, DT, PST, RAS, CT, Ca+2, Mg+2, Na+ and K+ and heavy metals. Analysis was performed, soil fertility, determining the infiltration rate, moisture content of soil and flow measurement. The results showed that the parameters considered most effective in evaluating the indicators of environmental impacts were: Suspended solid, turbidity, dissolved oxygen and Coliform termotelerantes. The concentrations of nitrate were below the limit established by CONAMA (2005). High levels of STD were found in the point P4. The risk of salinity in cacimb?o Lot 02, the water was classified as Class II, or medium risk of salinity in the remaining points was classified as Class I. The iron and aluminum were found high concentrations in four sampling points independent of the dry or rainy. On the ground, found high levels of phosphorus in both samples collected in the batch 01, as the lot 02. The pH levels found in samples of soil, the soil can be classified as neutral and moderate alkalinity. The high infiltration rate obtained in the tests performed in lots 01 and 02 indicated the high permeability of soil at these points / Impactos ambientais s?o definidos como os processos de mudan?as sociais e ecol?gicas causados por perturba??es no ambiente. Na agricultura s?o bastante diversificados, sendo que o uso intensivo do solo e de pr?ticas agr?colas inadequadas causa efeito negativo no meio ambiente, alem de afetar a produtividade das culturas e a qualidade de vida do homem. Diante disso, este trabalho teve por objetivo analisar par?metros indicadores de impactos ambientais no per?metro Irrigado Cruzeta. Durante o per?odo de julho de 2007 a mar?o de 2008 foram coletadas amostras no lote 01 e 02 do per?metro irrigado. O monitoramento foi realizado em quatro pontos de amostragem, sendo 3 (tr?s) localizados nos canais de irriga??o e 1 (um) localizado em um cacimb?o. Foram monitorados pH, CE, STD, SS, NO3 -, OD, DT, PST, RAS, CT, Ca+2, Mg,+2, Na+ e K+ e metais pesados. Foram realizadas an?lises de fertilidade do solo, determina??o da taxa infiltra??o, teor de umidade do solo e medi??o da vaz?o. Os resultados alcan?ados permitiram concluir que os par?metros analisados mais eficazes na avalia??o dos indicadores de impactos ambientais foram: SS, Turbidez; CT e oxig?nio dissolvido. As concentra??es de Nitrato ficaram bem abaixo do limite estabelecido pelo CONAMA (2005). Altos teores de STD foram encontrados no ponto P4. Quanto ao risco de salinidade, no cacimb?o do lote 02, a ?gua foi classificada como de classe II, ou seja, de m?dio risco de salinidade, nos demais pontos foi classificada como de classe I. Quanto ao ferro e alum?nio foram verificadas altas concentra??es nos quatro pontos de amostragem independente do per?odo seco ou chuvoso. No solo, foram encontrados altos teores de f?sforo tanto nas amostras coletadas no lote 01, quanto no lote 02. Os teores obtidos de pH nas amostras de solo, permitiram classificar os solos como neutro e de alcalinidade moderada. A alta taxa de infiltra??o obtida nos ensaios realizados nos lotes 01 e 02 indicou a alta permeabilidade do solo nestes pontos
