Foraminifera as Environmental Condition Indicators in Todos os Santos Bay (Bahia, Brazil)


The environmental quality of the marine area close to the Landulpho Alves Oil Refinery situated in Todosos Santos Bay (Bahia, Brazil) was assessed by statistical methods on foraminiferal assemblages, with species tolerant to low continental influence such as Ammonia tepida, Elphidium excavatum, Pseudononion atlanticum and Quinqueloculina spp., and to high organic matter such as Buliminella elegantissima and Bulimina marginata. We have found that Bolivina pulchella, Pseudononion atlanticum, Fursenkoina pontoni, Buliminella elegantissima, Bolivina striatula, Bulimina marginata, Quinqueloculina spp., Ammonia tepida, and Elphidium excavatum are opportunistic and tolerant to high levels of accumulated organic matter, and are associated to stations 6, 17, 18, 19, 21, 22, 23, 24, and 25, located mainly in the southern, outermost part of the Bay.
