Avaliação da presença de fármacos, por LC-MS/MS, em águas superficiais pré e pós-tratamento convencional por ensaio Jar-test e caracterização do risco humano / Evaluation of the presence of drugs by LC-MS/MS in surface water before and after conventional treatment by jar-test test and the characterization of human riskMariana Castello Novo Pais 03 June 2013 (has links)
O aumento crescente da população brasileira em combinação com o uso abusivo de medicamentos no mercado nacional, aliados à falta de saneamento básico e de políticas públicas para o correto gerenciamento de alguns tipos de resíduos têm resultado na presença de compostos farmacêuticos em ambientes aquáticos. Estudos indicam que várias dessas substâncias parecem ser persistentes no ambiente e algumas vezes, resistem até mesmo às estações de tratamento de água, fazendo-se presentes na água tratada, que chega à população. O presente trabalho visou analisar quantitativamente a presença dos anti-inflamatórios e do analgésico mais comumente consumido no Brasil: diclofenaco, cetoprofeno, naproxeno, indometacina, ibuprofeno e o paracetamol em águas superficiais, por LC-MS/MS com extração em fase sólida, antes e depois do tratamento convencional, em escala laboratorial pelo ensaio de Jar-Test, bem como caracterizar o risco humano pela presença destes compostos na água após o tratamento. Os métodos utilizados na quantificação destes fármacos apresentaram bons resultados: a análise cromatográfica obteve coeficientes de correlação entre 0,9952-0,9991, com limites de quantificação de 0,5ng/mL- 50ng/mL e desvios padrões entre (0,08-2,08); na recuperação do método de extração em fase sólida o diclofenaco, o cetoprofeno, o naproxeno e a indometacina apresentaram cerca de 100% de recuperação, o ibuprofeno apresentou apenas 48%(±9,37) de recuperação e o paracetamol aproximadamente 19,84% (±2,52); no ensaio de jar-test, observou-se que apenas o cetoprofeno e o ibuprofeno não foram removidos completamente no tratamento utilizado (remoção de 0-15% do cetoprofeno e de 0-35% do ibuprofeno). Amostras ambientais foram coletadas e tratadas pelo ensaio de Jar-Test, e os valores obtidos para o cetoprofeno e ibuprofeno após o tratamento foram de 18,67-19,65ng/L e 147ng/L, respectivamente. Através de cálculos, com a dose de referência de cada um dos compostos e considerando as características desta exposição, foi possível concluir que nestas concentrações o cetoprofeno e o ibuprofeno não causam risco à saúde humana. / The increasing population growth in combination with the misuse of drugs in the domestic market, coupled with the lack of sanitation and public policies for proper management of some types of waste have resulted in the presence of pharmaceutical compounds in aquatic environments. Studies indicate that several of these substances appear to be persistent in the environment and sometimes even resistant to water treatment plants, being present in the treated water which reaches the population. This study aimed to analyze quantitatively the presence of anti-inflammatory and analgesic most commonly consumed in Brazil: diclofenac, ketoprofen, naproxen, indomethacin, ibuprofen and paracetamol in surface waters by LC-MS/MS with solid phase extraction prior and after conventional treatment in a laboratory scale by using Jar-test assay, and to determine the human risk posed by the presence of these compounds in the water after treatment. The methods used to quantify these drugs showed good results: a chromatographic analysis obtained correlation coefficients between 0.9952 to 0.9991, with limits of quantification of 0.5 ng/mL- 50ng/mL and standard deviations between (0.08 - 2.08); recovery method of solid phase extraction to diclofenac, ketoprofen, naproxen and indomethacin showed about 100% recovery, ibuprofen showed only 48% (± 9.37) and paracetamol approximately 19 84% (± 2.52) recovery; in the jar-test, it was observed that only ketoprofen and ibuprofen were not completely removed (removal: 0-15% of ketoprofen and 0-35% of ibuprofen). Environmental samples were collected and handled by jar-test test, and the values obtained for ketoprofen and ibuprofen after treatment were 18.67 to 19.65 ng / L and 147ng / L, respectively. By calculation with a reference dose of each compound and considering the characteristics of this display, it was concluded that these concentrations of ketoprofen and ibuprofen do not cause risk to human health.

Nas águas do velho Chico : por uma arqueologia de ambiente aquáticos no baixo Rio São Francisco - Sergipe/AlagoasFreire, Luís Felipe 27 March 2013 (has links)
Fundação de Apoio a Pesquisa e à Inovação Tecnológica do Estado de Sergipe - FAPITEC/SE / The recent research aims at an idealization of an Archaeology of Aquatic Environment worried in inserting multiple voices in the process of the construction of the knowledge, making it possible to bring closer society to archaeological research and to its heritage. Through the presentation and the discussion of a theoretical-methodological framework of an integrative and multivocal bias and through the contextualization of the researched area, the lower São Francisco River, it’s sought to draw a line in a position in which Archaeology is capable to comprehend the many relationships existent between local communities and its archaeological heritage. Thus, the sub aquatic archaeology research rises as a form to mediate a relation of self-recognition of society to its underwater cultural heritage. / A presente pesquisa tem como objetivo a idealização de uma Arqueologia de ambientes aquáticos preocupada em inserir múltiplas vozes no processo da construção do conhecimento, para que seja possível aproximarmos a sociedade da pesquisa arqueológica e de seu patrimônio. Por meio da apresentação e da discussão de um arcabouço teórico-metodológico de viés integrativo e multivocal e da contextualização da área de pesquisa, o baixo rio São Francisco, busca-se delinear um posicionamento em que a Arqueologia seja capaz de compreender as diversas relações existentes entre as comunidades locais e o seu patrimônio arqueológico. Assim, a pesquisa arqueológica subaquática surge como uma forma de mediarmos uma relação de autorreconhecimento da sociedade para com o seu patrimônio cultural subaquático.

Instituto de Química. Programa de Pós-Graduação em Geociências-Geoquímica. Niterói, RJ / A contaminação dos ambientes aquáticos por contaminantes emergentes é,
ainda, pouco investigada no Brasil. Este estudo teve como objetivo avaliar a
ocorrência de fármacos de diferentes classes terapêuticas, cafeína e bisfenola,
em corpos hídricos de diferentes escalas no Estado do Rio de Janeiro.
Foram eles: em micro escala, os Córregos São Domingos e Ribeirão
Santíssimo (município de Santa Maria Madalena); em pequena escala, as
bacias dos rios Paquequer, Guandu, Iguaçu e Sarapuí; em média escala, a
bacia do médio rio Paraíba do Sul. Considerando os objetivos propostos foram
analisadas 47 amostras para a determinação de 34 fármacos (acetaminofeno,
ácido salicílico, codeína, diclofenaco, fenazona, ibuprofeno, ketoprofeno,
meloxicam, naproxeno, piroxicam, atorvastaina, benzafibrato, gemfibrozil,
alprazolam, carbamazepina, diazepam, lorazepam, venlafaxina, atenolol,
metoprolol, nadolol, propanolol, sotalol, furosemida, torasemida, glibenclamida,
irbesartan, losartan, valsartan, warfarina, tiabendazol, xilazina, sulfametoxazol,
trimetoprim), cafeína e bisfenol-a, empregando a técnica analítica de extração
em fase sólida, cromatografia a líquido de alta eficiência e espectrometria de
massa tandem. Os resultados obtidos mostraram que nenhuma amostra
analisada estava livre da contaminação por esses compostos e apenas dois
deles (piroxicam e torasemida) não foram detectados em qualquer amostra. A
freqüência com que os demais compostos foram detectados variou entre 2,1
(para a xilazina) e 100% (para ácido salicílico, velanfaxine, propanolol,
tiabendazol, trimetoprim e cafeína). Uma avaliação qualitativa sobre consumo
de medicamentos no município de Santa Maria Madalena mostrou uma estreita
relação entre o consumo, a concentração e a frequência com que são
encontrados fármacos em amostras ambientais. Os rios que apresentaram as
maiores concentrações totais destes contaminantes foram (em ordem
decrescente): rios Iguaçu-Sarapuí (51,8 μg L-1); córregos São Domingos e
Ribeirão Santíssimo (19,0 μg L-1); rio Paquequer (18,2 μg L-1); rio Guandu (1,46
μg L-1) e rio Paraíba do Sul (1,42 μg L-1). Esses resultados mostram a
importância da vazão na diluição da contaminação por fármacos, cafeína e
bisfenol-a, oriundos da entrada de esgoto doméstico, o que pode ser avaliada
através das cargas de contaminantes transportadas em cada bacia. A alta
concentração de certos compostos (alguns quantificados neste estudo na
ordem de μg L-1) não é, necessariamente, a principal preocupação ambiental,
mas também, a sua persistência e atividade biológica. Contudo, para a maioria
desses compostos não existem dados suficientes quanto a ocorrência,
avaliação de risco e ecotoxicidade, e desta forma, é difícil prever os seus
efeitos causados à saúde do homem e dos organismos aquáticos, o que torna
primordial a sua investigação / The contamination of aquatic environments by emerging contaminants is still
poorly investigated in Brazil. This study aimed to evaluate the occurrence of
different therapeutic classes of drugs, caffeine and bisphenol-a in water bodies
of different scales in the State of Rio de Janeiro. They were: in micro-scale, the
streams of São Domingos and Ribeirão Santíssimo (in the city of Santa Maria
Madalena); in a small-scale, the River Basins Paquequer, Guandu, Iguaçu and
Sarapuí; on the medium scale, the basin of the middle Paraíba do Sul River.
Considering the objectives proposed, 47 samples were analyzed for the
determination of 34 pharmaceutical compounds (acetaminophen, salicylic acid,
codeine, diclofenac, phenazone, ibuprofen, ketoprofen, meloxicam, naproxen,
piroxicam, atorvastatin, benzafibrate gemfibrozil, alprazolam, carbamazepine,
diazepam, lorazepam, venlafaxine, atenolol, metoprolol, nadolol, propranolol,
sotalol, furosemide, torasemide, glibenclamide, irbesartan, losartan, valsartan,
warfarin, thiabendazole, xylazine, sulfamethoxazole, trimethoprim), caffeine and
bisphenol-a, using the analytical technique of Solid Phase Extraction, High
Performance Liquid Chromatography and Mass Spectrometry tandem. The
results showed that any sample evaluated was free from contamination by
these compounds; only two compounds (piroxicam and torasemide) were not
detected in any sample. The frequency of compounds detected ranged from 2.1
(for xylazine) and 100% (for salicylic acid, velanfaxine, propranolol,
thiabendazole, trimethoprim and caffeine). A qualitative assessment about drug
use in the municipality of Santa Maria Madalena showed a close relationship
between the consumption, the concentration and the frequency wherein
pharmaceutical compounds are found in environmental samples. The rivers that
had the highest total concentrations of these contaminants were (in descending
order): Iguaçu and Sarapuí rivers, (51.8 mg L-1), and the streams São
Domingos and Ribeirão Santíssimo (19.0 mg L-1); Paquequer River (18.2 mg L-
1); Guandu River (1.46 mg L-1) and Paraíba do Sul River (1.42 mg L-1). These
results show the importance of flow in the dilution of the contamination by
pharmaceutical compounds, caffeine and bisphenol-a, from the entry of
domestic sewage, which can be evaluated through loads of contaminants
carried in each basin. The high concentration of certain compounds (some
quantified in this study in order mg L-1) is not necessarily the main
environmental concern, but also its persistence and biological activity. However,
for most of these compounds there are insufficient data regarding the
occurrence, risk assessment and ecotoxicology, and thus it is difficult to predict
the health effects in humans and aquatic organisms, which makes its primary
research

Etude des interactions matière organique dissoute : contaminants organiques dans l'environnement aquatiqueDe Perre, Chloé 16 December 2009 (has links)
Suite à une anthropisation généralisée des ressources aquatiques et des écosystèmes associés, on retrouve de nombreux contaminants chimiques organiques à l’état de traces dans l’environnement aquatique. En parallèle de ces contaminants, dans les milieux aquatiques on retrouve également des molécules rassemblées sous la dénomination « matière organique dissoute (MOD) », qui sont des mélanges complexes de molécules et macromolécules, qui peuvent s’associer à ces contaminants et influencer leur comportement et leur distribution. Les interactions entre MOD et contaminants peuvent s’avérer difficiles à étudier étant donné qu’elles sont dépendantes de nombreux facteurs tels que la nature des contaminants et de la MOD, ainsi que des paramètres physico-chimiques du milieu. L’objectif de ces travaux était donc d’étudier ces interactions. Les contaminants organiques choisis ont été les Hydrocarbures Aromatiques Polycycliques (HAP) et les substances pharmaceutiques. D’autre part, plusieurs types de MOD d’origine naturelle ou commerciale ont été utilisés. Pour étudier les interactions, plusieurs techniques analytiques ont été développées dont la micro-extraction sur phase solide couplée à la chromatographie en phase gazeuse et à la spectrométrie de masse et l’extinction de fluorescence. / In relation with a widespread human impact on aquatic resources and ecosystems, many organic chemical contaminants are present at trace levels in aquatic environments. In parallel to these contaminants, dissolved organic matter (DOM), which is composed of complex mixtures of molecules and macromolecules, is also found and could be associated with these contaminants and influence their behavior and distribution. Interactions between DOM and contaminants can be very difficult to understand because they depend on many factors such as the nature of contaminants and DOM, as well as on environmental physico-chemical parameters. The aim of this work was thus to study these interactions. Organic contaminants studied were Polycyclic Aromatic Hydrocarbons (PAHs) and pharmaceuticals. On the other hand, several types of natural and commercial DOM have been used. To study the interactions, several analytical techniques have been developed like solid phase microextraction coupled to gas chromatography and mass spectrometry and fluorescence quenching.

Sítios arqueológicos de naufrágios da Baía de Todos os Santos, Salvador-BA : estudo de caso do Clipper Blackadder / Archaeological sites of shipwreck at the Baía de Todos os Santos (all saints bay), Salvador, BA – BR : case study from the Clipper BlackadderGusmão, Daniel Martins 17 April 2015 (has links)
With a coast of approximately 8.500 km of extension, Brazil possesses a maritime scenario of
great archaeological potency, formed mainly by rests of shipwrecks, port structures, maritime
religiosity spaces, the sanctuary sites, and the depository sites. In the last twenty years of
scientifically archaeological research, we entered in an innovative reality proposal that intends
to encompass the many varied dimensions of human interaction with the aquatic environment,
through the analyses of the multiple social and material expressions arising from this
perception, be it from the nautical, maritime, or underwater segment corroborating in an
Archaeology of Aquatic Environment. In the intent to evaluate the development and the
perspective of this research field in Brazil, our dissertation has as one of its goals to do a
approach of archaeological sites formed by rests of shipwrecks at the All Saints Bay - Bahia,
relating historical, technical, nautical and social archaeological arising from this types of sites,
by means of a inventory liability until reaching the research in situ from the rests of the
clipper Blackadder. To this end we land in Public Archaeology, approaching segments of
society to better understand the importance and meaning of shipwrecks archaeological sites as
an integral part of the Underwater Brazilian Cultural Heritage. / Com um litoral de aproximadamente 8.500 km de extensão, o Brasil apresenta um cenário
marítimo de grande potencial arqueológico, formado principalmente por restos de
embarcações naufragadas, estruturas portuárias, espaços de religiosidade marítima, sítios
santuários, e sítios depositários. Nesses últimos 20 anos de pesquisas arqueológicas
científicas, ingressamos numa realidade de proposta inovadora que visa englobar as mais
variadas vertentes da interação do ser humano com o ambiente aquático, através da análise
das múltiplas expressões materiais e sociais advindas desta percepção, seja ela do segmento
marítimo, náutico ou subaquático corroborando numa Arqueologia de Ambientes Aquáticos.
No intuito de avaliar o desenvolvimento e as perspectivas deste campo de pesquisa no Brasil,
nossa dissertação tem como um dos objetivos desenvolver uma abordagem de sítios
arqueológicos formados por restos de embarcações naufragadas na Baía de Todos os Santos,
Salvador - BA, relacionando informações históricas, técnicas, náuticas e sociais advindas
desses tipos de sítios, por meio de um inventário passivo até alcançar a pesquisa in situ dos
restos do clipper Blackadder. Nessa perspectiva, nos aportamos na Arqueologia Pública,
aproximando segmentos da sociedade para melhor compreender a importância e significância
dos sítios arqueológicos de naufrágios como um elemento integrante do patrimônio cultural

A water resources quality assessment case study involving a package plant in Mogale cityDe Bruyn, Karin 11 1900 (has links)
Inadequately treated wastewater effluent is harmful to the receiving aquatic environment. Water-borne chemicals and microbial pathogens pose a health risk to anyone living downstream from sewage treatment facilities. This study assessed the effluent from a package plant with a design capacity of 48kℓ/24 hours, servicing 12 household units and a restaurant in Mogale City. Over a 12 month period, fortnightly water samples were collected from ten selected sites including two boreholes, a river and two dams. Standard parameters including physical (pH, EC, temperature, DO and SS), chemical (nutrient concentration) and biological (bacterial counts) were analysed using handheld meters, standard membrane filter techniques and colorimetric methods. One borehole was affected by pathogen and nitrate runoff from an adjacent poultry farm. If regularly monitored, the package plant effectively removed microbes (most samples contained 0 cfu/100mℓ) but above limit COD, ammonia and phosphate was released in the effluent (with maximum values of 322 mg/ℓ, 42.52 mg/ℓ and 7.18 mg/ℓ, respectively). Generally, river and dam water at the site was of good quality. / Environmental Science / M. Sc. (Environmental Science)

[en] ROBOTIC SYSTEM FOR MONITORING WATER QUALITY IN LENTIC ENVIRONMENTS / [pt] SISTEMA ROBÓTICO PARA MONITORAMENTO DA QUALIDADE DA ÁGUA EM AMBIENTES LÊNTICOSMARCOS AURELIO PINTO MARZANO JR 18 February 2019 (has links)
[pt] Nas últimas décadas, a crescente conscientização ambiental levou ao reconhecimento da necessidade do uso responsável dos recursos hídricos. Para garantir isso, a boa gestão de reservatórios hídricos requer um monitoramento ambiental adequado, com medições confiáveis dos parâmetros de qualidade da água em vários pontos do reservatório, permitindo o controle da qualidade da água e seus impactos na fauna, flora e comunidades ribeirinhas dos reservatórios. O monitoramento das variáveis ambientais dos reservatórios é atualmente realizado por processo tradicional de coleta manual. Infelizmente, no Brasil, as iniciativas de produzir um sistema robótico aquático com tecnologia nacional e de baixo custo, quando comparado a equivalentes importados, são ainda raras e se restringem a algumas poucas instituições acadêmicas, não tendo sido localizado nenhum fabricante comercial deste tipo de veículo no país. Visando preencher esta lacuna, o presente trabalho teve como objetivo o desenvolvimento do protótipo de um sistema robótico aquático capaz de se locomover autonomamente em lagoas, lagos e reservatórios, coletando informações físico-químicas da água e armazenando estes dados na memória. Além disso, foi incluído no protótipo uma câmera de vídeo, sistema de iluminação e um sistema de controle remoto, objetivando o controle pela equipe em terra. Nos testes realizados em dias ensolarados e chuvosos, o robô apresentou boa dirigibilidade, estabilidade e manobrabilidade. O vaso de pressão do sistema robótico resistiu às pressões necessárias durante os testes, a eletrônica conseguiu atender as especificações de projeto e o software conseguiu estabelecer um controle de navegação, cumprindo o trajeto de uma rota estabelecida. / [en] In recent decades, the growing environmental awareness has led to the recognition of the need for responsible use of water resources. To ensure this, the good management of water reservoirs requires adequate environmental monitoring, with reliable measurements of water quality parameters in various parts of the reservoir, allowing the control of water quality and its impacts on fauna, flora and riverine communities of the reservoirs. Monitoring environmental variables of the reservoirs is currently performed by traditional process of manual collection. Unfortunately, in Brazil, initiatives to produce a water robotic system with national and low cost technology, compared to imported equivalents, are still rare and restricted to a few academic institutions, and no commercial manufacturer of this type of vehicle was found in the country. Aiming to fill this gap, the main objective of this study was to develop a prototype of a water robotic system capable of autonomously navigate in ponds, lakes and reservoirs, collecting physicochemical information of water and storing this data in memory. Moreover, a video camera, illumination and a remote control system were included in the prototype, allowing the team on the ground to control the prototype. In tests conducted in sunny and rainy days, the robot presented good handling, stability and maneuverability. The robotic system pressure vessel resisted pressures required during testing, the electronics met the design specifications and the software was able to establish a navigation control, fulfilling the path of an established route.

Využití plynové chromatografie s hmotnostně spektrometrickou detekcí pro posouzení kontaminace odpadních a povrchových vod rezidui léčiv / Application of Gas Chromatography with Mass Spectrometric Detection for the Assessment of Drug-residue Contamination of Wastewaters and Surface WatersLacina, Petr January 2012 (has links)
This work is based on the current issue of increasing concentrations of pharmaceutical residues in various components of the environment. These new environmental contaminants continuously enter the environment. The most affected environmental component is the aquatic environment. This study is focused on the development and optimization of reliable analytical method, which can determine selected drugs in the aquatic environment (waste waters and surface waters) qualitatively and quantitatively. The target compounds were selected mainly from the group of non-steroidal anti-inflammatory drugs (NSAID): salicylic acid, acetylsalicylic acid, clofibric acid, ibuprofen, acetaminophen, caffeine, naproxen, mefenamic acid, ketoprofen and diclofenac. NSAIDs are one of the most used drugs in Czech Republic. For the final analysis of this study was used the comprehensive two-dimensional gas chromatography with mass spectrometric detection Time-of-Flight (GCxGC-TOF MS). It is a very sensitive and reliable analytical method for trace and ultra-trace analysis. Simultaneously, solid phase extraction (SPE) and derivatization are optimized in this work. Optimized analytical method including SPE, derivatization with MSTFA (N-methyl-N-(trimethylsilyl) trifluoroacetamide) and final analysis by GCxGC-TOF MS were applied successfully for the analysis of real samples. Samples of waste water were collected from the waste water treatment plant in Brno – Modřice and samples of surface water were collected from two river streams Svratka and Svitava in Moravian region. The range of concentrations of selected drug residues varied from one to tens of g/L in wastewater and from tens to hundreds of ng/L in surface waters. The degree of wastewater and surface waters contamination by drug residues is assessed in conclusions of the work. Simultaneously, spontaneous degradation of selected drugs in water and removal efficiency of the wastewater treatment plant is assessed in conclusions of the work. The developed method is usable for monitoring and environmental analysis of water ecosystems. It is usable not only for selected drugs, but even for other organic compounds with similar properties.
