210-Pb activity is an useful technique in environmental investigation, todetermine sediments accumulation rates, geochronology, and to study metals.Its activity decline exponentially with depth, and is inversely proportional to thesedimentation rate at non-impacted ecosystem. Dating of sediments, combinedwith chemical profile, allow the study of the impact events in coastal zones.In the present study, we have investigated the history of metals concentrationsand sedimentation rates of recent s...
