1. 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

2. Análise morfológica e molecular de cianobactérias isoladas de efluentes de uma mina de urânio desativada com ênfase em Aphanothece e sua capacidade de biossorção do 226Ra / Morphological and molecular analysis of cyanobacteria isolated from a deactivated uranium mine effuents with emphasis in Aphanothece and its 226Ra biosorption capacity
Cyanobacteria are oxygenic photosynthetic microorganisms with wide metabolic and structural plasticity, which have biotechnological potential for exploration in metals biosorption and organic pollutants biodegradation. Due to its strong interactions with cations and a reliable supply of cheap biomass, cyanobacteria may be a promising biosorbent candidate for

3. Biosorption of cadmium by yeast Saccharomyces cerevisiae. / Biossorção de cádmio por leveduras Saccharomyces cerevisiae.
O aumento das atividades industriais intensificou os problemas com poluição ambiental por metais pesados e principalmente por cádmio, por ser dentre os metais pesados, muito utilizado em vários processos industriais e por ser extremamente tóxico em baixas concentrações, além de causar sérios problemas de saúde. Dentre vários processos utilizados n

4. Estudo da remoção dos ions cromo(III) e cobre(II) em colunas de leito fixo pela alga marinha Sargassum sp
The increasing concern with the environment question and the severity of the legislation in discarding industrial and domestic effuents containing metals has motivated the search for new technologies of recovery and removal of metals. The metal removal with biomass of microorganisms has been investigated as an alternative to the traditional methods of metal

5. Fotodestruição de compostos potencialmente toxicos utilizando TiO2 e luz solar
The destruction of potentially toxic compounds by photocatalysis was studied in this work in two different systems: a) the system using colloidal TiO2, where the influence of silver deposits was evaluated for the photodegradation of phenol. b) the system using TiO2 P 25 supported on a glass plate as part of a plug flow reactor using solar light as source of
