Article Synopsis
- The study develops a new method to analyze metal contamination and mobility in the marine sediments of Sepetiba Bay, Brazil, focusing on metals like Cd, Cu, Ni, Pb, and Zn.
- It utilizes a chemical model to assess bioavailability through the SEM/AVS ratio and a geostatistical model to evaluate metal mobility.
- Findings indicate that Sepetiba Port, the urban area, and river discharges are key sources of these metals, particularly concentrated in the NE part of the bay, where metals are less mobile and not bioavailable due to their association with sulfides and organic matter from nearby mangroves.
