Geochemical Background of the Itacaiúnas River Basin II

The research continues the environmental monitoring of the Itacaiúnas River Basin, focusing on strategic areas for mining. The aim is to deepen the geochemical characterization of soils, stream sediments, and surface waters, incorporating new approaches such as magnetic susceptibility analysis and the use of lead (Pb) and strontium (Sr) isotopes to trace contamination sources.

The initiative is justified by the need to distinguish between natural concentrations of potentially toxic elements and anthropogenic contamination, especially in a region marked by intense economic activity and urban sprawl. The data obtained in the previous project (2017-2018) showed that the anomalies observed mostly reflect the geological environment. However, the growing pressure on the territory requires continuous and more detailed monitoring, also paying attention to the bioavailability and bioaccessibility of the elements, which indicate the real potential for environmental risk.

The use of radiogenic isotopes of Pb and Sr makes it possible to precisely trace the sources of contamination, while the analysis of magnetic susceptibility in soils from the Itacaiúnas River Basin helps to understand the influence of the geological environment on the chemical composition. The integration of these tools increases the capacity for environmental diagnosis and management.
