Abstract Purpose Some marine organisms can be used as Biological Quality Elements to estimate the degree of environmental impact and monitor health benthic habitats. Organisms with mineralized protections, such foraminifera, provide helpful information on evolution coastal system over a long period determine Paleo-Ecological Status (Paleo-EcoQS). This work aims at reconstructing Paleo-EcoQS in heavily anthropized Sepetiba Bay (SB; Rio de Janeiro State, SE Brazil). Materials methods is based multiproxy approach, including textural, geochemical, foraminiferal data along core SP11 retrieved near Pico da Marambaia (a mountain tip Barrier Island). Geochemical analyses encompassing total organic carbon (TOC), sulfur (S), nitrogen (N), calcium carbonate (CaCO 3 ), stable isotopes matter ( OM δ 13 C, 15 N) elemental concentrations well 201 Pb, 137 Cs, radiocarbon dating were performed characterize bay. Results The values Paleo-EcoQS.st (standardized Paleo-EcoQS) index indicate that paleoenvironmental quality varied from moderate good between ≈50 AD ≈1500 high ~ 1920s 1990s. Since 1990s, has deteriorated considerably, probably due deposition contaminated dredging material nearby areas. Ballast water discharge may have introduced alien species, Ammonia buzasi , into SB. Conclusions results obtained SP11, compared those another (i.e., SP8) area, suggest reference level maximum not always reached before industrialization ecosystems significant interaction ocean; natural factors, related, for example, sedimentary dynamic processes or geomorphological changes, lead unexpected results.
