Pollutant concentrations in a sediment core dated by Th-isotopic ratios and the ²¹⁰Pb dating method

In this research we have dated a sediment core in an estuarine system (southwest of Spain) strongly contaminated by anthropogenic activities, making use of the enhanced levels of some natural radionuclides from uranium series found in the upper layers of the core due to these activities and applying the ²¹⁰Pb dating method in the remaining ones. This chronology has allowed to explain the concentration profile along the sediment core of some heavy metal (Fe, Cu, Zn and U), which have been introduced in this estuary by mining and industrial activities.
