1. Estudo da influência de compostos recalcitrantes na remoção de matéria orgânica biodegradável no tratamento de efluente de refinarias de petróleo / Studies of hard-to-degrade compounds influence on removal of biodegradable organic material from petroleum refinery wastewaters
Petroleum Refinery wastewaters (PRW) have hart-to-degrade compounds, such as: phenols, ammonia, cyanides, sulfides, oils and greases and the mono and polynuclear aromatic hydrocarbons: benzene, toluene and xylene (BTX), acenaphthene, nitrobenzene and naphtalene. It is known that the microrganisms activity can be reduced in the presence of certain substances,

2. Determinação de fontes de hidrocarbonetos policíclicos aromáticos e alifáticos em sedimentos de ambientes aquáticos
Numerical values of polycyclic aromatic hydrocabons and n-alkanes distribution indexes of sediments are important tools to elucidate the origins of hydrocarbons mixtures. Polycyclic aromatic ratios are sensitive indicators of petrogenic and pyrogenic inputs, while n-alkanes distribution usualy discriminates biogenic from petrogenic sources. The study area of
