Full textMy thesis is developed for the particular case of satellites observations from geostationary orbit. The overall aim was to characterize the diel variability of water inherent (i.e. the particulate beam attenuation and backscattering coefficients, cp and bbp) and apparent (i.e. reflectance, R) optical properties (“shape”of diel cycle, amplitude, seasonal variations, origins). These properties determine the signal which is observed from sensor aboard satellite. This study is a preliminary step in understanding the physical problem, before assessing the possibility of quantifying the diel variability from satellite observations. Diel variability of cp and bbp is studied by season, as defined by physical and trophic conditions: mixing, bloom proliferation, its decline, and oligotrophy. Both cp and bbp are characterized by a diel cycle of daytime increase and nighttime decrease, confirming known general trends. This occurs across all seasons, but intra-seasonal variability differed between cp and bbp cycles: unlike bbp, cp show larger amplitude of diurnal variation during the bloom cp and bbp minima are synchronized while bbp minima are attained 3-6 h before those of cp, except during the bloom. Daily changes of R are consistent with the variations of bbp. Nevertheless, it is still difficult to reproduce the diurnal increase of bbp by inversion of R. The differences observed between in situ and modeled values of bbp suggest that the performance of inversion is degraded when it is used at high frequency

There has been increased focus on the environmental impact of automobile emissions in recent years. These environmental concerns have resulted in the creation of more stringent particulate matter emissions regulations in the United States and European Union. These limits have forced diesel engine manufacturers to reduce particulate matter (PM) emissions by an order of magnitude beginning in 2007. Diesel particulate filters (DPF) provide the most effective means of reducing PM emissions from diesel exhaust. DPFs can reduce over 99% of PM in the exhaust. DPF effectiveness is limited by the accumulation of ash. Ash is comprised of incombustible material from engine lubricants. Engine oil additives based on P, Zn, S, Ca, and Mg are responsible for the majority of ash. Ash accumulation in DPFs reduces their useful life by plugging the filter's inlet channels. Ash deposition leads to increased pressure drop across the DPF, which reduces the engine's performance and negatively impacts fuel economy. The process of ash accumulation in DPF channels is not well understood. This research is focused on exploring the ash interactions with DPF walls, pores, and the catalyst washcoat. Based on scanning electron microscopy analysis of ash loaded DPFs from the field and from filters loaded with ash in the laboratory, a mechanism for ash accumulation is presented.

Full textIn this study an analysis of the dispersion of particulate matter generated by stationary sources is proposed, by applying Computational Fluid Dynamics (CFD) tools, using an Eulerian model for the flow and a Lagrangean model for the particles, under steady-state conditions in the Fluent software. The model validation is presented in two sessions, the first comprises the study of the atmospheric flow under conditions of neutral stability, including the effects of the heterogeneities of the terrain. In this case, the air flow past a 126m high hill in real scale was adopted. Different turbulence models were compared: standard k-?, k-? RNG and parametrized k-?. The three models presented similar performance and described satisfactorily the trends of the experimental data. Subsequently, the Lagrangean model based on the Eddy life time (DRW - Discrete Random Walk) was used to represent the distribution of particulate matter concentrations in a confined environment. The numerical results satisfactorily describe the particle concentration profiles, but underestimate the values in the region near the wall, which would indicate that a better approximation of the particle deposition should be considered. After these studies, this Eulerian- Lagrangean approach was applied to the case of dispersion of particulate material under neutral atmosphere conditions in a region around the city of Santa Gertrudes-SP, where the Ceramic Complex is responsible for the largest production of ceramic tiles in Brazil. Transit of trucks on unpaved roads has been identified as a source of particulate matter that reaches the urban perimeter of the city. The contributions of the activities related to mining and the preparation of the soil for agricultural use were also studied, although this last one does not add a significant load when compared with the two previous ones. In addition to the influence of the mentioned sources, industrial sources located inside the city also contribute to the scenario.

Full textThere are strong evidences regarding negative effects of gestational exposure to air pollution. However, the mechanisms of action of air pollutants are not well established. Maternal anomalous physiological changes during pregnancy may cause permanent changes in offsprings, that might initiate future diseases in adult life. Therefore, the study of those maternal changes during pregnancy is important. Metabolomics is defined as the global analysis of the metabolome of an organism in comparative studies, for the measurement of relative changes in the metabolite abundance, appearance or disappearance. Metabolomics might provide a better understanding of cellular functioning at the molecular level. In this work, an experimental study of maternal gestational exposure to fine particulate matter (PM2.5) was accomplished to evaluate the effects of this exposure to the metabolism, by an untargeted metabolomics analysis of urine from pregnant mice exposed to PM2.5 or to filtered air during pregnancy. A chromatographic and sample preparation methods for urinary untargeted metabolomics analysis by HILIC-MS were optimized. For the chromatography optimization, the influence of mobile phase additives, salt concentration and pH, as well as, the gradient ramp were investigated. The best condition was chosen by the evaluation of peak shape, relative intensity and retention time CV of 15 selected m/z, as well as, the total number of molecular features and the intensity CV of those molecular features. The best condition comprises of 20 mmol/L of ammonium formate as solvent B, and 95% acetonitrile and 5% 400 mmol/L of ammonium formate as solvent A, in the composition of the mobile phase. For the sample preparation, different solvents, along with, their mixtures were examined for the urine protein precipitation. Isopropanol was the solvent that presented the best results for sample preparation. Thus, after the analytical method optimized, urine samples from the progenitors were submitted to untargeted metabolomics analysis by HILIC-MS. The animals\' metabolome were significantly changed by the gestational exposure to particulate matter. It was observed changes in the levels of carnitines, amino acids, peptides, among others. There is some indication that the air pollution has altered the gut microbiota, due to the enhancement of trimethylamine N-oxide (TMAO), a metabolite that is also related to the atherosclerosis process. The level of metabolites related to histidine metabolism were also altered due to PM2.5 exposure. Carnitine and acylcarnitine levels were also increased in the test group, suggesting an altered energy production in the mitochondria.

Atualmente, um dos maiores problemas mundiais é a poluição atmosférica, oriunda essencialmente de fontes antrópicas. Os grandes impactos ambientais, como a degradação da qualidade do ar, são resultados dos processos de desenvolvimento urbano e industrial. O material particulado (MP) tem sido alvo de vários estudos devido aos efeitos nocivos causados ao meio ambiente e a saúde humana. O arsênio, um metalóide que apresenta características tanto de metal como de não-metal, é considerado altamente tóxico. A associação do arsênio ao material particulado pode provocar sérios danos à saúde da população. Os níveis de toxicidade do arsênio são dependentes de sua forma química. As espécies inorgânicas de arsênio, arsenito (AsIII) e arseniato (AsV), são também consideradas agentes carcinogênicos. O Recôncavo Baiano é uma região que apresenta grande importância ambiental, social e econômica para o estado da Bahia. Nesta área encontram-se portos, terminais marítimos e diversos pólos industriais que são as principais fontes de emissão de poluentes para o meio ambiente. O presente trabalho teve por objetivo verificar a concentração do arsênio presentes tanto nas partículas finas, quanto nas partículas grossas do material particulado atmosférico do Recôncavo Baiano, para avaliar as contribuições deste poluente à saúde da população exposta. A determinação de arsênio em material particulado, utilizando a digestão, com HNO3, e a técnica de espectrometria de fluorescência atômica acoplada à geração de hidreto (HG-AFS), mostrou-se eficiente para a matriz estudada com limite de detecção e quantificação de 0,3 ng m-3 e 1 ng m-3, respectivamente. As concentrações médias de arsênio, obtidas no material particulado em algumas regiões do Recôncavo Baiano, estavam em torno de 30 ng m-3, valor cinco vezes maior que o recomendado pela União Européia (6 ng m-3). O arsênio presente no material particulado encontra-se substancialmente nas partículas finas. Alertando para os riscos de exposição da população, nos municípios onde foram feitas as amostragens. Os resultados apresentados neste trabalho são indicativos da necessidade de se atualizar os padrões de qualidade do ar para o Brasil, incluindo outros poluentes como o arsênio
