1. Química Sem Fronteiras: o desafio da energia
Coal, natural gas and petroleum-based liquid fuels are still the most widely used energy sources in modern society. The current scenario contrasts with the foreseen shortage of petroleum that was spread out in the beginning of the XXI century, when the concept of "energy security" emerged as an urgent agenda to ensure a good balance between energy supply and

2. Avaliação de eficiência de ensaios ecotoxicológicos na detecção de toxicidade em efluentes de refinaria de petróleo
Uma das principais fontes de poluição dos recursos hídricos são os efluentes líquidos industriais. Dentre esses, destacam-se os efluentes de refinaria de petróleo, pois geram efluentes bastante complexos e de difícil tratabilidade. Desta forma, evidencia-se a necessidade de monitoramento contínuo da qualidade desses efluentes, uma vez que são consid

3. DEVELOPMENT OF METHOD FOR DETERMINATION OF AS, SB AND SE IN BIODIESEL AND PETROLEUM BY INDUCTIVELY COUPLED PLASMA OPTICAL EMISSION SPECTROMETRY WITH SAMPLE INTRODUCTION BY HYDRIDE GENERATION (HG ICP / DESENVOLVIMENTO DE MÉTODO PARA DETERMINAÇÃO DE AS, SB E SE EM BIODIESEL E PETRÓLEO POR ICP OES COM INTRODUÇÃO DE AMOSTRA POR GERAÇÃO DE HIDRETOS
With the increasing world population and the consequent increasing in industrial activities and fuel consumption, chemical pollution has been a major problem of the XXI century. Alternatives that can minimize such problems are targets of researches, such as the use of biodiesel, a renewable and less polluting fuel. Elements usually found in low concentration

4. Análise crítica da utilização de modelagem matemática na avaliação da dispersão de efluentes leves no litoral da Baixada Santista ( Estado de São Paulo). / The analysis of mathematical models in the assessment of effuents dispersion in Baixada Santista coastline (State of São Paulo).
The prediction of the hydrodynamic water circulation and pollutants dispersion, mainly in coastal areas, has been a problem that engineers have been facing. This is due to the increase environmental impacts that involve coastal engineering work and management. The usage of mathematic modeling as assessment tool is necessary for these studies. The main purpos

5. Cério: propriedades catalíticas, aplicações tecnológicas e ambientais
Cerium based-compounds have great importance in a wide range of technological applications, such as: fuel cell devices development; metallurgic processes, petroleum refining; glass and ceramic production. Recently, its catalytic properties have been also explored for environmental applications, especially those to prevent or to control atmospheric and water

6. Análise das respostas citogenotóxicas e histopatológicas do peixe Trematomus newnesi exposto à água do mar diante da Estação Antártica Brasileira "Comandante Ferraz", Ilha Rei George, Antártica / Analysis of cytogenotoxic and histopathologic responses of the fish Trematomus newnesi exposed to seawater in front of the Brazilian Antarctic Research Station "Comandandante Ferraz", King George Island, Antarctica.
Many countries have installed research stations in Antarctica. Petroleum hydrocarbons and the sewage disposed into the sea by the stations are potential sources of pollution in Antarctica. Trematomus newnesi specimens were used to assess genotoxic potential and histopathology of the liver and gills of the water surrounding the Brazilian Antarctic Station ?Co

7. EVALUATION OF SEAWATER CONTAMINATION WITH BENZENE, TOLUENE AND XYLENE IN THE UBATUBA NORTH COAST, SP REGION, AND STUDY OF THEIR REMOVAL BY IONIZING RADIATION / "Avaliação da contaminação da água do mar por Benzeno, Tolueno e Xileno na região de Ubatuba e estudo da degradação destes compostos por radiação ionizante"
A major concern with leaking petroleum is the environmental contamination by the toxic and low water-soluble components such as benzene, toluene, and xylenes (BTX). These hydrocarbons have relatively high pollution potential because of their significant toxicity. The objective of this study was to evaluate the contamination of seawater by the main pollutants

8. Biomarcadores funcionais e histológicos associados à exposição do peixe prochilodus lineatus ao óleo diesel
Considerando-se o elevado número de acidentes com petróleo e seus derivados que vem ocorrendo atualmente no Brasil e a escassez de trabalhos sobre os efeitos destes contaminantes nos organismos aquáticos, testes de toxicidade voltados para a avaliação dos efeitos destes poluentes em espécies de peixes de ambientes neotropicais são necessários e urgen

9. Limonologia e qualidade ambiental de um corpo lêntico receptor de efluentes tratados da indústria de petróleo / Limnology and environmental quality of lagoon receiver petroleum effluents treated
Environmental pollution has become a subject of public interest throughout the world. Not only have developed countries been affected by environmental problems but also the developing nations have started to suffer from the serious impacts of pollution. Within this context it is necessary to collect simplified environmental data to assist in the management o

10. Co-incineração e co-processamento de residuos industriais perigosos em fornos de clinquer : investigação no maior polo produtor de cimento do pais, região metropolitana de Belo Horizonte, MG, sobre os riscos ambientais, e propostas para segurança quimica
This thesis presents the results of the research realized in the years 1998 to 2002 about the principal technological, energetic, territorial and environmental aspects related with the hazardous industrial wastes processing in the c1inker kilns of cement plants. The analysis considered this activity a complex system with risks and uncertainly, because occur,

11. Petroleum Pollution Bioremediation Using Water-Insoluble Uric Acid as the Nitrogen Source
The biodegradation of hydrocarbon pollutants in open systems is limited by the availability of a utilizable nitrogen source. This limitation can be overcome by using uric acid. Enrichment cultures grown on crude oil-uric acid media yielded mixed and pure cultures that degraded petroleum. In a simulated open system, uric acid bound to crude oil and was availa

12. Characterization of microbial isolates from an estuarine ecosystem: relationship of hydrocarbon utilization to ambient hydrocarbon concentrations.
Water collected at 12 sites in the Neuse River estuary of North Carolina was analyzed for total viable counts on three isolation media (Trypticase soy agar [TSA], marine agar 2216, Sabouraud agar) and total hydrocarbons by fluorescence spectroscopy. Counts of 3.9 X 10(1) to 3.8 X 10(3) cells/ml were found for total heterotrophs, well within the range commonl
