Essa contaminação pode ocorrer por derramamentos acidentais, por evaporação e na grande maioria, pela corrosão dos tanques subterrâneos. Para minimizar tais efeitos e atender as demandas ambientais, diversas técnicas de remediação podem ser empregadas. Neste sentido, este trabalho busca avaliar as técnicas de remediação aplicadas para conter a contaminação por hidrocarbonetos em água subterrânea e solo em postos de combustíveis do Estado de São Paulo, através da revisão de técnicas de remediação e da compilação de estudos de casos. Estes estudos foram desenvolvidos nas cidades de Itaporanga, Itaí, Taguaí, Cachoeira Paulista, Caraguatatuba, Avaré, Santo André e São Sebastião com a aplicação das seguintes técnicas de remediação: Biorremediação, Bombeamento e Tratamento, Remoção de Gases, Extração de Vapores do Solo (SVE) e Extração Multifásica (MPE). Os principais resultados mostram que as técnicas de remediação utilizadas em todos os casos apresentaram resultados satisfatórios conseguindo remover grande parte dos contaminantes na fase livre atenuando também na fase dissolvida. Em alguns casos analisados, a associação de técnicas como injeção de Ar no Solo (AS), Extração de Vapores do Solo, Extração Multifásica e Biorremediação proporcionaram aumento de potencial e consequente diminuição do tempo da remedição. / In Brazil, the contamination by hydrocarbons of groundwater and soil, in particular by diesel oil and by gasoline, has been the subject of several surveys, due to the large number of contamination areas and the complexity of soil interaction phenomena. This contamination can be caused by accidental spills, by evaporation and in the great majority by the corrosion of the underground tanks. To minimize such effects and meet environmental demands, various remediation techniques may be employed. In this sense, this work tries to evaluate the remediation techniques applied to contain the contamination by hydrocarbons in groundwater and soil in fuel stations of the State of São Paulo, through the revision of remediation techniques and the compilation of case studies. These studies were carried out in the cities of Itaporanga, Itaí, Taguaí, Cachoeira Paulista, Caraguatatuba, Avaré, Santo André and São Sebastião with the application of the following remediation techniques: Bioremediation, Pumping and Treatment, Gas Removal, Soil Vapor Extraction EVS) and Multiphase Extraction (MPE). The main results show that the remediation techniques used in all cases presented satisfactory results, being able to remove much of the contaminants in the free phase, also attenuating in the dissolved phase. In some cases, the association of techniques such as soil air injection (AS), soil vapor extraction, multiphase extraction and bioremediation have led to an increase in potential and consequent reduction of remediation time. / CAPES

Introduction: Impaired neurocognition, especially social cognition, predicts disability in schizophrenia. Early intervention to target impairment is theoretically attractive as a means to minimise chronic disability. Many trials confirm that Cognitive Remediation (CR) produces meaningful, durable improvements in cognition and functioning but few interventions remediate social cognition or focus on the early stages of schizophrenia. Methods: A systematic review and meta-analysis of 11 randomised controlled trials (RCTs) of CR in first episode psychosis (FEP) was completed. A randomised controlled pilot trial was then conducted to investigate a combined CR and social cognition training (CR+SCT) intervention in FEP compared to CR alone, assessing cognition, functioning and symptoms at baseline and follow-up. Qualitative feedback was also obtained in a nested feasibility and acceptability study to assess engagement, intervention suitability and attrition. Results: In the systematic review and meta-analysis, random effects models revealed a non-significant effect of CR on global cognition in FEP. However, there was a significant effect on functioning and symptoms, which was larger in trials with adjunctive psychiatric rehabilitation and small group interventions. In the pilot trial, the CR+SCT group had significantly better social functioning scores post-treatment, especially on the interpersonal relationships scale, however there was no significant effect on social cognition. CR+SCT also improved visual learning and set-shifting. There was no specific effect on symptoms. The nested feasibility and acceptability study found CR and CR+SCT to be acceptable and feasible for early intervention in psychosis service users, with high engagement rates and high user-reported satisfaction. Users perceived improvements in neurocognition and reported using strategies learnt during CR in daily life. Conclusions: Meta-analysis suggests that CR is beneficial in FEP. Evidence from the pilot trial shows that a CR intervention enhanced with SCT can improve functioning more than CR alone and that such an intervention is feasible and acceptable. A larger RCT is required to explore the full benefits of a CR+SCT intervention compared to CR and treatment as usual.

The purpose of this study was to evaluate different types of metal decontamination from waste water. Specifically, to evaluate water from the mire located at Slagnäs railway depot. Through a literature review from Swedish authorities and entrepreneurs regarding water remediation methods have been compiled and compared. Methods for waste water remediation are chemical methods, sedimentation and filtration. Standardized methods for decontamination are constantly updated with new materials and improved methods. Neither one of these methods are relevant on their own. The idea behind the experiment was to use Fenton reaction on the mire water which would contribute to precipitation of metals. Within the study an experiment with hydrogen peroxide and sodium hydroxide was performed. The idea behind the experiment was to use Fenton reaction on the mire water which would contribute to precipitation of metals. No conclusions can be drawn about hydrogen peroxide also known as Fentons reaction due to lack of analysis results. Trials with sodium hydroxide shown that the best results occur when pH is moderately adjusted at pH 6 and 7. Due to incomplete analytical results no conclusion about Fenton reaction as a waste water treatment method can be drawn based on this experiment. The lack of results is probably due to the continuous reaction between Fentons and organic matter.

Effect of Organic Amendments on Phosphorus Fractionation in a Lead-Contaminated Urban Soil Abstract: A sequential phosphorus extraction scheme was applied to a lead-(Pb) contaminated soil in Herculaneum, MO for both a field and incubation study. The objectives of this project were; (1) lower soil P fixation and retention through the addition of organically amended P sources; (2) identify the distribution of P among five operationally defined pools of extractable phosphate following treatment incorporation; (3) determine portion of labile P derived from vermicompost (VC); and (4) identify treatments that could potentially lower bioaccessible Pb over an eight-week period. Sequential fractionation identified the Aluminum-associated P (Al-P) fraction as the fraction responding the most to treatment addition. Retention as Al-P could be effectively reduced using the organic amendments evaluated in this study in combination with VC. Amended triple super phosphate (TSP) and VC lowered bioaccessible Pb concentration compared to a non-amended plot. This finding may provide some experimental justification for the application of VC in combination with TSP to Pb-contaminated soil. Further research focusing on a combination of these P sources applied to Pb-contaminated soil could elucidate the conclusion postulated by this research.

abstract: In situ remediation of contaminated aquifers, specifically in situ bioremediation (ISB), has gained popularity over pump-and-treat operations. It represents a more sustainable approach that can also achieve complete mineralization of contaminants in the subsurface. However, the subsurface reality is very complex, characterized by hydrodynamic groundwater movement, geological heterogeneity, and mass-transfer phenomena governing contaminant transport and bioavailability. These phenomena cannot be properly studied using commonly conducted laboratory batch microcosms lacking realistic representation of the processes named above. Instead, relevant processes are better understood by using flow-through systems (sediment columns). However, flow-through column studies are typically conducted without replicates. Due to additional sources of variability (e.g., flow rate variation between columns and over time), column studies are expected to be less reproducible than simple batch microcosms. This was assessed through a comprehensive statistical analysis of results from multiple batch and column studies. Anaerobic microbial biotransformations of trichloroethene and of perchlorate were chosen as case studies. Results revealed that no statistically significant differences were found between reproducibility of batch and column studies. It has further been recognized that laboratory studies cannot accurately reproduce many phenomena encountered in the field. To overcome this limitation, a down-hole diagnostic device (in situ microcosm array - ISMA) was developed, that enables the autonomous operation of replicate flow-through sediment columns in a realistic aquifer setting. Computer-aided design (CAD), rapid prototyping, and computer numerical control (CNC) machining were used to create a tubular device enabling practitioners to conduct conventional sediment column studies in situ. A case study where two remediation strategies, monitored natural attenuation and bioaugmentation with concomitant biostimulation, were evaluated in the laboratory and in situ at a perchlorate-contaminated site. Findings demonstrate the feasibility of evaluating anaerobic bioremediation in a moderately aerobic aquifer. They further highlight the possibility of mimicking in situ remediation strategies on the small-scale in situ. The ISMA is the first device offering autonomous in situ operation of conventional flow-through sediment microcosms and producing statistically significant data through the use of multiple replicates. With its sustainable approach to treatability testing and data gathering, the ISMA represents a versatile addition to the toolbox of scientists and engineers. / Dissertation/Thesis / Ph.D. Civil and Environmental Engineering 2013

Estudos a respeito das dificuldades de aprendizagem tem se tornado o foco de pesquisas nacionais e internacionais. Destacam-se, principalmente, aqueles que priorizam os aspectos da intervenção, pois são notáveis os progressos acadêmicos, emocionais e sociais dos indivíduos com dificuldades de leitura e escrita. Com relação às dificuldades de aprendizagem e as dificuldades escolares, a literatura revela a necessidade da identificação precoce e propõe programas de remediação fonológica que têm como objetivo treinar as habilidades metalinguísticas e o ensino da relação letra-som, necessários para a aprendizagem do sistema de escrita. Alguns autores propõem intervenções por meio de treino computadorizado, outros autores, além do treino, propõem a associação do mesmo a atividades de leitura e escrita. Considerando o exposto, o objetivo deste estudo foi verificar os efeitos de um programa de remediação fonológica, associado a atividades de leitura e escrita, dentro do processo de alfabetização e letramento em alunos com dificuldades de aprendizagem, que frequentam uma sala de recursos multifuncionais. Foram selecionados 10 alunos na faixa etária entre 7 e 11 anos de idade, de ambos os gêneros, com dificuldades de aprendizagem, participantes de uma sala de recursos multifuncionais. Os participantes foram divididos em 2 grupos: Grupo Experimental (6 alunos) e Grupo Comparativo (4 alunos). O GE foi submetido ao programa de remediação fonológica a fim de comparar os resultados da aplicação do programa aos alunos do GC, que inicialmente não receberam a intervenção. Foram realizadas avaliação pré e pós ao programa a fim de verificar o desempenho dos participantes nas habilidades do processamento fonológico, leitura e escrita, memória auditiva e visual. Os atendimentos foram em grupos de 3 alunos, realizados uma vez por semana, com duração de 50 minutos. Os resultados revelaram que o desempenho do grupo submetido ao programa foi superior ao do grupo não submetido. Observou-se que a remediação fonológica, associada a atividades de leitura e escrita, promoveu melhoras nas habilidades de leitura e escrita em alunos com dificuldades de aprendizagem das salas de recursos multifuncionais. / Studies on learning difficulties have become the focus of national and international research. Of particular note are those who prioritize aspects of the intervention, since the academic, emotional and social progress of individuals with reading and writing difficulties is remarkable. With regard to learning difficulties and school difficulties, the literature reveals the need for early identification and proposes phonological remediation programs that aim to train the metalinguistic abilities and the teaching of the letter-sound relationship, necessary for the learning of the writing system. Some authors propose interventions through computerized training, other authors, besides the training, propose the association of the same to activities of reading and writing. Considering the above, the objective of this study was to verify the effects of a phonological remediation program, associated to reading and writing activities, within the process of literacy in students with learning disabilities, attending a multifunctional resource classroom. We selected 10 students aged 7 to 11 years of age, of both genders, with learning difficulties, participants of a multifunctional resource room. Participants were divided into 2 groups: Experimental Group (6 students) and Comparative Group (4 students). The EG was submitted to the phonological remediation program in order to compare the results of the application of the program to CG students, who did not initially receive the intervention. Pre and post evaluation of the program were carried out to verify the performance of participants in the phonological processing, reading and writing skills, auditory and visual memory. The visits were in groups of 3 students, held once a week, lasting 50 minutes. The results showed that the performance of the group submitted to the program was superior to that of the group not submitted. It was observed that phonological remediation, associated with reading and writing activities, promoted improvements in reading and writing skills in students with learning difficulties in multifunctional resource rooms.

O objetivo principal desta pesquisa foi desenvolver um aparato e procedimento experimental para estudar a oxidação química de organoclorados por injeção de ozônio em escala de laboratório. A concepção do ensaio desenvolvido permite realizar ensaios de coluna em meio aquoso ou em meio poroso, saturado ou não saturado, com monitoramento da concentração e da pressão absoluta de ozônio na entrada e na saída da coluna, do pH, da temperatura do meio, da temperatura ambiente e controle da vazão. Nesta pesquisa foram realizados ensaios para verificar a degradação de PCE em fase dissolvida em concentração de saturação em diversos meios: água ultrapura, águas subterrâneas coletadas em um poço cacimba e em um poço tubular profundo, e soluções de bicarbonato de sódio. A investigação experimental compreendeu ensaios de saturação e decaimento de ozônio, ensaios batch e ensaios de coluna em meios com valores de pH variados. Os resultados indicaram que o ozônio em fase dissolvida atinge a saturação após aproximadamente 15 minutos de injeção, com concentrações saturadas variando entre 90 e 170 µmol/L, dependendo do meio aquoso de estudo. O decaimento biexponencial do ozônio dissolvido mostrou tempos de meia vida t1 e t2, que variaram conforme o meio de estudo, entre 4 e 26 minutos, e 14 e 193 minutos, respectivamente. O decaimento monoexponencial resultou em tempos de meia vida entre 12 e 76 minutos. Os ensaios batch em meio aquoso mostraram degradação significativa do PCE por ozônio dissolvido comparativamente à degradação em água ultrapura não ozonizada. A adição de bicarbonato de sódio diminuiu os tempos de meia vida do ozônio em água, mas não intensificou a degradação do PCE em sistema fechado (ensaios batch). Os ensaios de coluna em meio aquoso indicaram que a volatilização e o arraste são os principais mecanismos de remoção de PCE por injeção de ozônio. As concentrações de PCE em fase dissolvida observadas no início do ensaio de coluna foram quase completamente volatilizadas e recuperadas no trap, tanto nos ensaios com a injeção de oxigênio quanto nos ensaios com injeção de ozônio. As concentrações de PCE na coluna no final dos ensaios foram inferiores ou ligeiramente superiores ao valor de intervenção estabelecido pela CETESB em 2014. Os ensaios de coluna em meio sólido (microesferas de vidro e areia) indicaram que ocorre degradação do PCE, com remoção quase total na coluna, porém com menor recuperação no trap. Possivelmente, o maior tempo de residência na coluna favorece as reações do ozônio com o PCE. / The aim of this research was to develop experimental apparatus and procedure to investigate chemical oxidation of chlorinated organic compounds by ozone injection at laboratory scale, in aqueous media and in saturated or unsaturated porous media. The test allows control of ozone inlet and outlet pressures and concentrations, pH, room and column temperature, and ozone flow. In this research, tests were performed to investigate degradation of PCE dissolved at maximum solubility concentration in several media: ultrapure water, groundwater collected in a shallow well and in a deep well, and sodium bicarbonate solutions. The experimental investigation comprised ozone saturation and decay tests, batch tests, and column tests in aqueous media with several pH values. Results indicated that dissolved ozone reaches saturation after approximately 15 minutes of injection, at saturated concentrations between 90 and 170 µmol/L, depending on the aqueous medium. Second order ozone decay half lives t1 and t2 vary, respectively, between 4-26 minutes and 14-193 minutes depending on the aqueous medium. First order decay half lives varied between 12-76 minutes. Batch tests in aqueous media showed significant PCE degradation by dissolved ozone as compared to degradation in non ozonized ultrapure water. Addiction of sodium bicarbonate decreased ozone half-lives in water but did not intensify PCE degradation as observed in the results of batch tests. Column tests in aqueous media evinced that stripping and volatilization are the mains mechanisms of PCE removal by ozone injection. Initial concentrations of dissolved PCE in the column were almost completely volatilized and recovered in the trap, for ozone injection as well as for oxygen injection. Final concentrations of dissolved PCE in the column were in the order of ppb and very near the limit allowable value according to the environmental agency of the state of São Paulo. Column tests in solid media indicate that PCE degrades and is removed from the column, but not totally recovered in the trap; probably, the more extended residence time in the column enhances reactions of ozone and PCE

A biorremediação minimiza o impacto de substâncias recalcitrantes no ambiente. O dispersante químico pode promover a biodegradação mais rápida do óleo, mas a sua aplicação deve ser sempre avaliada por profissionais especializados em meio ambiente, já que ela pode ser vista como uma introdução deliberada de um contaminante. O presente trabalho avaliou a influência da utilização de um dispersante químico e de um biossurfactante (produzido pelo fungo Aspergillus fumigattus), em derrame controlado de óleo diesel, ocorrido na primavera/2003 na Ilha dos Cavalos localizada no estuário da Lagoa dos Patos. O ambiente foi monitorado durante seis meses, selecionando-se um local com óleo diesel, outro com óleo diesel e dispersante químico e outro com óleo diesel e biossurfactante. Foram analisados os seguintes parâmetros físico-químicos: granulometria, pH, Eh, COT, nitrogênio e fósforo total do sedimento, hidrocarbonetos alifáticos e aromáticos. O tratamento estatístico consistiu na análise de variância (ANOVA) e no teste de Tukey (p< 0,05), para os nutrientes analisados. Os hidrocarbonetos aromáticos e alifáticos provenientes da degradação do óleo diesel foram determinados por CG-MS. Os resultados mostraram que o uso de técnicas alternativas, principalmente com a introdução de espécies não nativas, deve ser bem estudado antes de ser aplicado, pois na caixa onde houve adição do fungo Aspergillus fumigattus a biota microbiana demorou a se recuperar, e a taxa final de degradação nas três caixas foram muito parecidas. / The conventional cleaning techniques of infected areas with petroleum and its derived products can be complemented by remediation, with the use chemical surfactants or biosurfactants. Bioremediation minimizes the impact of recalcitrant substances in the environment. The chemical surfactant can promote fast oil biodegradation, however, its application should always be evaluated by specialized professionals in environment, in order do avoid the understanding it is a deliberated introduction of a pollutant. In such case, this work evaluated the influence of using a chemical surfactant and a biosurfactant (produced by the fungus Aspergillus fumigattus) in a controlled spill caused by oil diesel, that happened during the springtime of the year 2003, in the Horses Island, located in the estuary of the Patos Lagoon. The environment was monitored for six months, and there were areas with only oil diesel, only oil diesel and chemical surfactant and, finally, areas with oil diesel and biosurfactant. The following physical-chemical parameters were analyzed: granulometry, pH, Eh, COT, nitrogen and aliphatic and aromatic hydrocarbons. The statistics consisted of variance analysis (ANOVA) and Tukey test (p <0,05), related to the analyzed nutrients. The aliphatic and aromatic hydrocarbons derived from oil diesel were determined by GC-MS. The results showed that the use of alternative techniques, mainly with the introduction of non native species, should be meticulous studied before the application, because in the box where the fungus Aspergillus fumigattus was added there was an important delay in the recovering of microbial biota, although the degradation final rate was very similar in the three boxes.

Resultado da realização de determinadas atividades, como indústrias, depósitos, disposição de resíduos, a contaminação do solo e das águas subterrâneas é um tema que só num passado muito recente ganhou certa evidência, em razão dos efeitos danosos ao meio ambiente e à saúde em geral e da descoberta e divulgação de casos que se tornaram emblemáticos. Na cidade de São Paulo, a reutilização de locais com tais características tem ocorrido muitas vezes de modo impróprio, num contexto de mudanças de uso do solo em função da alteração do perfil econômico da cidade. A existência dessas áreas contribui efetivamente para a deterioração do espaço urbano, com conseqüências imediatas na paisagem. A contaminação, no entanto, não significa a inviabilização da utilização de uma área, desde que procedimentos adequados sejam adotados, o que pode representar uma oportunidade para a requalificação de importantes regiões da cidade. Dessa forma, o objeto deste trabalho compreende o estudo das potencialidades e das limitações apresentadas na formulação, implantação e monitoramento de projetos paisagísticos em áreas contaminadas na cidade de São Paulo. / Result of the performing of certain activities, such as industries, warehouses, waste disposal, the soil and groundwater contamination is a theme which has gained certain prominence in a very recent past, due to the damaging effects to the environment and the health in general as well to the discovery and revealing of cases that became emblematic. In the city of São Paulo, the reuse of places with such characteristics has frequently occurred in an inappropriate way, within a context of change of the land use as a result of the modification in the economical characteristics of the city. The existence of those areas contributes effectively to the deterioration of the urban space with immediate consequences to the landscape. The contamination, however, doesn?t mean the unfeasibility of the reuse of an area, since the right procedures are adopted, which may represent an opportunity of requalification of important regions of the city. Thus, the object of this work deals with the study of the potentialities and the limitations presented in the formulation, implementation and monitoring of landscape designs in contaminated sites in the city of São Paulo.

Tem sido sugerido que a função do sistema olivocolear medial pode ser avaliado por meio da supressão das emissões otoacústicas transientes (EOATs). A função desse sistema tem sido estudada em crianças com distúrbio do PA devido à sua suposta ação na melhora da discriminação auditiva e inteligibilidade de fala em ambientes ruidosos. Objetivo: Analisar o processamento auditivo e o efeito de supressão das EOATs em crianças com dislexia. Além disso, analisar o efeito de um programa de remediação fonológica, de leitura e escrita no PA. Material e Método: Os sujeitos foram divididos em três grupos: GE1: 23 crianças com dislexia; GE2: 15 crianças do GE1 foram reavaliadas após serem submetidas à remediação fonológica, de leitura e escrita; GC: 28 crianças de escola pública, sem queixas auditivas e escolares. Foram realizados os procedimentos: anamnese, avaliação audiológica básica, avaliação do PA e supressão das EOAs. Resultados: As crianças com dislexia apresentaram desempenho estatisticamente inferior ao do GC nos testes: memória sequencial não verbal (MSNV), teste dicótico de dígitos (TDD), teste de padrão de duração (TPD), teste de padrão de frequência (TPF), e gaps in noise (GIN) - orelha esquerda. O GE1 não apresentou supressão das EOAs. Não houve correlação entre os testes de PA e os valores de supressão das EOATs em nenhum grupo avaliado. As crianças do GE2 apresentaram melhora estatisticamente significante no desempenho nos testes TDD, TPD, TPD e GIN pós remediação. Apenas os meninos apresentaram supressão das EOAs na etapa pós remediação. Conclusão: As crianças com dislexia deste estudo apresentaram alteração nos testes de PA, principalmente na habilidade auditiva de ordenação temporal.

It has been suggested that the function of the medial olivocochlear system can be evaluated by the suppression effect of the transient otoacoustic emission (TOAE). This system's function has been studied in children with disorder of AP because of its supposed actions on the improvement of auditory discrimination and speech intelligibility in noisy environments. Aim: Analyze the auditory processing and the suppression effect of transient otoacoustic emission (TOAE) in children with dyslexia, and analyze the effect of phonological, reading and writing remediation program in the AP. Material and Method: Children were divided in three groups: GE1: 23 dyslexia children; GE2: 15 children of GE1 were evaluated again after phonological, reading and writing remediation program; GC: 28 children of public school, without hearing or learning disabilities. Procedures were performed: anamnesis, basic audiologic evaluation, AP tests and suppression of OEA. Results: Children with dyslexia presented performance statistically inferior than GC in nonverbal sequential memory test (NSMT), dichotic digit test (DDT), pitch and duration pattern sequence test (PPS and DPS) and gaps in noise (GIN) - left hear. GE1 didn't present suppression of OAE. There wasn't correlation between the AP tests and the supression of OEA in any of the evaluated groups. The children of GE2 presented improvement statistically significant in performance in: DDT, PPS, DPS and GIN after remediation program. Only boys presented suppression of OEA in pos testing. Conclusion: Children with dyslexia from this study presented alteration in AP tests, mainly in auditory ability of temporal ordering. Phonological, reading and writing remediation were able to improve the auditory abilities of children with dyslexia from this study / Mestrado / Saude da Criança e do Adolescente / Mestre em Saude da Criança e do Adolescente
