| Abstract | Guanabara bay receives a large amount of industrial and domestic sewage, which contributes for its environmental degradation. For monitoring those environmental changes, two cores from the northeastern area of the bay were analized. They were subsampled in centimeter intervals and the laboratory treatment followed specific methodology for foraminifera. Foraminifera are much sensitive microorganisms as to environmental changes as to anthropogenic ones, thus they are useful as pollution indicators. The results show low values of diversity, however, a higher diversity in the core T15, between Paqueta island and Sao Goncalo than in the core T14, at Sao Goncalo south region. Both of them presented Ammonia tepida as a dominant species human pollution bioindicator, and Buliminella elegatissima as bioindicator of high levels of organic matter. |
