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.
In recent years, the region surrounding Sepetiba Bay (SB; SE Brazil) has become a hub of intense urban expansion and economic exploitation in response to ore transport and industrial and port activities. As a result, contaminants have been introduced into the bay, leading to an overall worsening of the environmental quality. The present work applies for the first time a foraminiferal morphology-based approach (M) and eDNA-based metabarcoding sequencing (G), along with geochemical data to assess the ecological quality status (EcoQS) in the SB.
