Determination of total and available fractions of PAHs by SPME in oily wastewat...
Gomes, R. C. B.; Nogueira, R.; Oliveira, J. M.; Peixoto, J.; Brito, A. G.Background, aim, and scope Polycyclic aromatic hydrocarbons (PAHs) are often found in oily wastewaters. Their presence is usually the result of human activities and has a negative effect on the environment. One important step in addressing this problem is to evaluate the effectiveness of PAH removal by biological processes since these are the most cost-effective treatments known today. Many techniques are pres...
Kinetics of fluorene biodegradation by a mixed culture
Gomes, R. C. B.; Nogueira, R.; Oliveira, J. M.; Peixoto, J.; Brito, A. G.The present study intended to determine the kinetics of biological degradation of fluorene by a mixed culture of microorganisms. Batch experiments were performed, being the inoculum an enriched mixed culture from a contaminated wastewater. Fluorene was quantified in the aqueous phase by solid phase micro-extraction (SPME), and analyzed in a GC-FID. The mixed culture was able to degrade fluorene and experimental...
Biodegradation kinetics of acenphtylene, flourene and phenantrene : a comparati...
Gomes, R. C. B.; Dykiert, F. X.; Nogueira, R.; Oliveira, J. M.; Peixoto, J.; Brito, A. G.Polycyclic Aromatic Hydrocarbons (PAH) are environmental contaminants produced in many human activities and presents toxic and carcinogenic characteristics. Their low solubility in water leads to slow biodegradation rates and consequently environmental persistence. The present work intends to determine the degradation rates of three aqueous phase PAH’s (acenphtylene, flourene and phenantrene) by a mixed culture...
Sistema de informação para a modelação matemática de derrames de hidrocarboneto...
Gomes, R. C. B.Dissertação de mestrado em Tecnologia do Ambiente. ; O Trabalho realizado teve como objectivo a construção de um sistema de informação para a modelação matemática de derrames de hidrocarbonetos em ambiente marinho (SIMDHAM). Com este sistema pretende-se criar uma ferramenta de gestão e apoio à decisão em situações de acidentes com produtos petrolíferos derramados em águas costeiras. Desta forma, foram identif...
