“…In addition, bottom sediments of the estuary also displayed low total PAH concentrations (maximum of 70 ng/g), but with the presence of PAH compounds such as pyrene, chrysene, benzo(b)fluoranthene, benzo(a)pyrene (Molisani et al, 2013b) that are described as carcinogenic PAHs and proven to be genotoxic (Hamoutene et al, 2002;Jha, 2004;Lemos et al, 2007;Weber et al, 2013). As a consequence of oil derivative presence in the estuary, high levels of such compounds in mussel from the estuary were found (2,876-6,101 µg/kg) (Santiago et al, 2016), values close to those reported in 2007 for mussel tissue from Guanabara Bay (4,000-6,000 µg/kg) by Francioni et al (2007). Along the Macaé coast, PAH concentrations in mussel from Santana Island have increased in the last 10 years from 75 µg/kg to 120 µg/kg, exemplifying the temporal increasing concentration of such compounds in the coast.…”

“…In addition, other activities such as navigation and urbanization have increased the presence of oil derivatives and compounds such as polycyclic aromatic hydrocarbons (PAHs) in the estuary. As a consequence, high PAH levels on mussel from the estuary were found, ranging from 2,876-6,101 µg/kg, which were typical of polluted areas (Santiago et al, 2016). Furthermore, many other biological effects have been found in the estuary, such as the catfish protective enzymatic responses to PAHs from the estuarine waters and sediments (Berenger, 2013); high concentrations of Cr in mussels (Santiago et al, 2016); fish abnormalities during embryonic development and juvenile growth (Nascimento, 2015); and mortality of amphipods exposed to estuarine sediments (Molisani et al, 2013a).…”

Some metals and PAHs may be genotoxic at certain levels (Jha, 2004), therefore, our aim was to evaluate the levels of genotoxicity that these waters may cause in the known animal model.…”

“…A degradação ambiental citada pelos professores e capturada pelas suas lentes, também é registrada em artigos científicos produzidos por diferentes pesquisadores. Por exemplo, em estudos sobre alterações ambientais no estuário do rio Macaé, com modificações em níveis celulares dos peixes (BEREGER et al, 2018;CONCEIÇÃO et al, 2017;SANTIAGO et al, 2016). Diminuição da quantidade e qualidade da água frente as demandas presentes e futuras deste recurso devido ao uso inadequado do solo (ESTEVES et al, 2015).…”

Resumo: Esse artigo aborda analiticamente resultados de um projeto de extensão universitária de formação continuada de professores da educação básica da rede municipal. As oficinas de formação continuada realizadas durante o projeto tiveram por finalidade discutir os aspectos visíveis e invisíveis da cidade Macaé (RJ) e culminaram na produção colaborativa de um documentário sobre o tema "Macaé invisível", realizado nesse mesmo local. Exploramos, portanto, neste texto, as visões dessa cidade expressas pelos professores e suas relações com o processo educativo. Este trabalho de extensão possibilitou perceber a forte sensibilização dos professores com as populações e com os trabalhos invisibilizados -incluindo seus estudantes o próprio trabalho docente. Palavras-chave: Educação. Invisibilidade social. Questões urbanas. Produção audiovisual.Área Temática: Educação. Teachers and the invisibles cities: knowledge generated in collective process of audiovisual productionAbstract: We analyze the results of a university extension project of continuing education of basic education teachers. Focused on teachers of the municipal network, the workshop discussed the visible and invisible aspects of the city and culminated in the collaborative production of a documentary on the theme "Invisible Macaé", on the same place. So we explore, in this text, the visions of this city expressed by teachers and their relationships with the educational process. This extension project allowed teachers to reflect collectively about invisible populations and invisible jobs -including their students and their own teaching work.

“…The municipality of Macaé is the main onshore operational basin for offshore oil exploration in Campos Basin, the largest oil reserve of the Brazilian continental shelf. Because of this, its coastal ecosystems, such as the Macaé River estuary and adjacent coast, already display a polluted status and adverse effects on biological resources (Molisani et al, 2013 a, b;Santiago et al, 2016). In this context, biotransformation and antioxidant enzymes could be used as biomarkers for determining the impact of oil derivatives, such as diesel oil, which is highly employed in local navigation, car traffic, and others.…”

The contamination of coastal areas by petroleum and its derivatives is a relevant issue based on large-scale production and consumption. This study presents field and laboratory surveys on the detoxification enzymes on the estuarine/coastal catfish Genidens genidens to understand the enzymatic responses to oil derivatives and environmental conditions. Field catalase (CAT) and glutathione S-tranferase (GST) measurements suggest oxidative stress and acting repair mechanisms in fishes, but were not induced by diesel oil as indicated by laboratory studies. On the other hand, higher ethoxyresorufin-O-deethylase (EROD) activities following higher polycyclic aromatic hydrocarbon (PAH) concentrations in the estuarine waters suggested fish responsiveness to oil contamination, mainly due to the fact that such EROD values were similar to the magnitude measured in fish during a 24-h exposure to diesel oil in the laboratory. However, other environmental estuarine conditions may also act on field EROD activities since PAHs concentrations in the water-soluble fraction of diesel oil (WSFDO) were higher than those measured in estuarine waters.
