1. Geochemical Investigation of Tar Balls Collected in a Brazilian Beach Using Biomarkers, Ni/V, δ13C Ratios and Ultra-High Resolution FT-ICR Mass Spectrometry
Representative tar balls collected in two distinct years (2012 and 2014) in a beach along the State of Bahia, northeastern Brazil, were geochemically characterized in order to identify correlations between them and investigate potential sources. Terpanes and steranes biomarkers (detected by gas chromatography coupled to mass spectrometry, GC-MS), carbon stab

3. Temporal changes in biological traits of diatom communities in response to an oil spill in a subtropical river
Abstract: Diatom growth strategies, which are used as a proxy to analyze disturbances and environmental impacts, can also provide reliable information about environmental gradients. In this study, we used diatom communities and biological traits to assess the structure of epilithic diatoms after an oil spill in a large tributary of the Iguaçu River (Paraná

4. Green polyurethane synthesis by emulsion technique: a magnetic composite for oil spill removal
Abstract After the consolidation of the Brazilian biodiesel industry, issues related to the final destination of the glycerin, the by-product from the biodiesel industrial process, drawing the attention of several researchers. There are several uses to this byproduct. Among them, the obtaining of polymers, such as polyurethane (PU), are very encouraged since

5. Quick stimulation of Alcanivorax sp. by bioemulsificant EPS2003 on microcosm oil spill simulation
Oil spill microcosms experiments were carried out to evaluate the effect of bioemulsificant exopolysaccharide (EPS2003) on quick stimulation of hydrocarbonoclastic bacteria. Early hours of oil spill, were stimulated using an experimental seawater microcosm, supplemented with crude oil and EPS2003 (SW+OIL+EPS2003); this system was monitored for 2 days and com

6. The fate of an oil spill in São Sebastião channel: a case study
A ruptura de um oleoduto em maio de 1994 introduziu 2.700 tons de óleo cru no Canal de São Sebastião, contaminando algumas áreas. Na ocasião um monitoramento de hidrocarbonetos em sedimentos estava sendo realizado na região, utilizando o método de cromatografia em fase gasosa/ detecção por ionização de chama. Os dados obtidos nesse monitoramento f

7. Caracterização batimétrica e fisicooceanográfica do canal de acesso ao porto de Cabedelo/PB: uma análise ambiental ao derrame de óleo
The State of Paraíba is one of the most dynamic states of Brazil, strategically located in the northeast, is notable for the excellent potential for integration of different transportation modes forming the states of Rio Grande do Norte, Pernambuco and Alagoas. The dynamic that occurs with port activity causes changes in the space where it is installed. And

8. DeterminaÃÃo dos Ãndices de sensibilidade ambiental ao derramamento de Ãleo do litoral da Ilha de SÃo Tomà / Determining the levels of environmental sensitivity to oil spill off the coast of Sao Tome
Acidentes por derrames de petrÃleo no mar causam danos irreversÃveis para o meio ambiente, para melhor tratar e prever os acidentes desde as Ãltimas dÃcadas diversos paÃses adotaram planos de contingÃncia, avaliaÃÃo de risco e de vigilÃncia marinha no combate à poluiÃÃo por petrÃleo. Inicialmente, esses planos eram baseados apenas em observaÃÃ

9. Desenvolvimento de um sistema computacional para geração automática de mapas de vulnerabilidade como ferramenta de auxílio às ações de prevenção ao derramamento de óleo em áreas costeiras
The northern portion of the Rio Grande do Norte State is characterized by intense coastal dynamics affecting areas with ecosystems of moderate to high environmental sensitivity. In this region are installed the main socioeconomic activities of RN State: salt industry, shrimp farm, fruit industry and oil industry. The oil industry suffers the effects of coast

10. Oil spill modeling off the Brazilian eastern coast: the effect of tidal currents on oil fate
O presente estudo teve por objetivo realizar modelagens de diferentes cenários de derramamentos de óleo em blocos de petróleo (BM-CUM-1, BM-CUM-2, J-M-259 e ES-M-418) em áreas adjacentes ao Recife de Abrolhos, a fim de verificar o efeito da maré no espalhamento do óleo na plataforma leste brasileira. Foram realizadas simulações de 30 dias de derramam

11. Impact of oil spill and posterior clean-up activities on wrack-living talitrid amphipods on estuarine beaches
Um estudo sazonal da geomorfologia e fauna de seis praias estuarinas na baia de Paranaguá, Brasil, foi interrompido bruscamente pela explosão e posterior afundamento do navio chileno Vicuña, que derramou 291 toneladas de óleo bunker. As praias que foram afetadas pela deposição de óleo e pelas posteriores atividades de limpeza, tinham sido amostradas d

12. Numerical model of oil spill as an environmental management method in contingency plan, applied to São Sebastião channel (SP). / Modelagem numérica do comportamento de derrames de óleo como método de gestão ambiental, em planos de contingência, aplicada ao canal de São Sebastião (SP).
The application of numeric models for analysis of oil spill in the coastal environments becomes one of the most important ways to understand the behavior of the oil in this case of impact, giving subsides to the prediction of the displacement of the patches and allowing best efficiency in the control of the extension of the impact agent. These assumptions gi
