Combined SEM/AVS and attenuation of concentration models for the assessment of bioavailability and mobility of metals in sediments of Sepetiba Bay (SE Brazil)

► The chemical/geostatistical modeling predicts metals bioavailability and mobility. ► There are potential sources of metals in Sepetiba Bay. ► In the NE area of Sepetiba Bay the high levels of metals have lowest mobility. ► The metals in Sepetiba Bay tend to be non-bioavailable.
