1. 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. 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

12. RemoÃÃo de tiofeno utilizando adsorventes preparados por mistura fÃsica
The need for cleaner fuels has increased that the studies aimed at reducing levels of sulfur in gasoline. The presence of sulfur compounds in fractions of oil is highly undesirable because it results in corrosion and environmental pollution. The hydrodesulfurization is the main process responsible for removing sulfur from most of the fuel industry of oil ref
