Article Synopsis
- The study examines the environmental degradation of Sepetiba Bay, Brazil, focusing on the impact of toxic elements on living benthic foraminifera.
- It utilizes a multiproxy approach, correlating benthic foraminiferal species density with pollutants like arsenic and lead, revealing a poor ecological quality status, especially in inner bay areas.
- The findings suggest that specific tolerant foraminifera species can indicate environmental health, making the study significant for coastal ecosystem management and biomonitoring efforts.
The quantitative assessment of the carbonate system represents one of the biggest challenges toward the "Sustainable Development Goals" defined by the United Nations in 2015. In this sense, the present study investigated the Spatio-temporal dynamics of the carbonate system and the effects of the El Niño and La Niña phenomena over the Cabo Frio upwelling area. The physical characterization of the site was carried out through data on wind speed and sea surface temperature.

For this purpose, four transects were conducted with an approximate length of 357 km (each one) through the platform and continental slope of the Sergipe-Alagoas sedimentary basin. Water samples were then collected in vertical profiles measuring from 5 to 1,799 meters depth, totaling 34 stations.
