1. FATORES DE EMISSÃO E DE ENRIQUECIMENTO DA CROSTA PARA ELEMENTOS TRAÇO (MP2,5) EMITIDOS PELA FROTA VEICULAR NA REGIÃO METROPOLITANA DE SÃO PAULO, BRASIL
Air pollution can cause several negative impacts on health and the environment. In large urban centers, this pollution is directly related to anthropogenic activities, mainly activities in the transportation sector. This study analyzed data on black carbon, fine particulate material (PM2.5) and its main trace elements from automotive vehicles (S, P, K, V, Cr

2. Transporte de material dissolvido em superfície impermeável sob chuva artificial analisado com a aplicação do delineamento experimental das faces centradas
RESUMO O estudo do escoamento superficial e transporte de poluentes é de grande importância, pois ajuda na prevenção de impactos ambientais, auxiliando em planejamentos a serem realizados pelo poder público. Neste trabalho, teve-se como objetivo estudar, em laboratório, a dinâmica do transporte de material (cloreto de sódio - NaCl) disposto sobre uma

3. Estimativa da emissão de poluentes pelo setor de transporte e análise das ocorrências de doenças respiratórias na área de proteção ambiental do Sistema Cantareira / Estimation of pollutant emissions by sector and transport analysis of respiratory diseases in the area of environmental protection System Cantareira
The global energy matrix is mainly composed by fossil fuels which when burned release air pollutants that affect the environment and human health. In this sense, monitoring health problems related to air pollution is important because it reinforces the need for change in national and international energy policies. This thesis presents a discussion on air pol

4. Poluição veicular: Avaliação dos impactos e benefícios ambientais com a renovação da frota veicular leve na cidade de São Paulo / Vehicle pollution: Analysis of the impacts and environmental benefits concerning the replacement of light vehicles in São Paulo City
This study presents an analysis of the levels of vehicles emissions related to the pollution problems in São Paulo City. Using a methodology called bottom-up, this thesis presents a theoretical evaluation on the rates of pollutants coming out the exhaust pipe of the largest light vehicles fleet in Brazil. Issues related to daily city activities such as the

5. Uma modelagem do transporte e reações dos ciclos do carbono e do nitrogênio no Lago Igapó 1 - Londrina, Paraná
A presente dissertação é uma contribuição para um melhor entendimento do efeito que uma descarga de poluentes pode causar no corpo d água do lago Igapó 1, localizado na região central da cidade de Londrina, Paraná. Para simular a dinâmica da concentração dos poluentes em todo o corpo d água do lago Igapó 1, propomos um modelo bidimensional, na

6. Extração do óleo e caracterização dos resíduos da borra de petróleo para fins de reuso
The petroleum industry, in consequence of an intense activity of exploration and production, is responsible by great part of the generation of residues, which are considered toxic and pollutants to the environment. Among these, the oil sludge is found produced during the production, transportation and refine phases. This work had the purpose to develop a pro

7. FLUX AND TRANSPORT STUDY OF PURE GASOLINE AND GASOLINE BLENDED ETHANOL IN UNSATURATED POROUS MEDIA / ESTUDO DO FLUXO E TRANSPORTE DE GASOLINA PURA E MISTURADA COM ETANOL EM MEIOS POROSOS NÃO SATURADOS
The subsurface release of water immiscible pollutants (NAPLs) due to leaks in storage tanks or pipelines and spilling transportation accidents is of great concern, since the NAPL or its constituents may migrate through the vadose zone until reaching the water table and eventually contaminate clean water sources. In Brazil, most of the gas stations store etha

8. Biodegradabilidade de n-Hexadecano por bactÃrias livres e imobilizadas em quitosana
Petroleum and its derivatives are introduced in ecosystems through leaking in reservoirs or by activities related with the extration, transportation, storage, processing, manipulation and disposal. In general these compounds are harmful to the health of the organisms, being able to cause serious environmental damages. In front of this problem there is an inc

9. Diretrizes para gestÃo ambiental de um empreendimento metro-ferroviÃrio: estudo de caso: Metrà do Recife
Due to its particularities, the undertaking of the urban railway transportation systems present in its set of characteristics (extension of the tracks, number of stations, integrated terminals, construction time, number of parties involved, etc) the need for a profound study in order to understand it in its all dimension. It has become all the more evident w

10. Effects of formaldehyde on the frog's mucociliary epithelium as a surrogate to evaluate air pollution effects on the respiratory epithelium
The increasing use of alcohol as an alternative fuel to gasoline or diesel can increase emission of formaldehyde, an organic gas that is irritant to the mucous membranes. The respiratory system is the major target of air pollutants and its major defense mechanism depends on the continuous activity of the cilia and the resulting constant transportation of muc

11. Microbial production of surfactants and their commercial potential.
Many microorganisms, especially bacteria, produce biosurfactants when grown on water-immiscible substrates. Biosurfactants are more effective, selective, environmentally friendly, and stable than many synthetic surfactants. Most common biosurfactants are glycolipids in which carbohydrates are attached to a long-chain aliphatic acid, while others, like lipope
