CNPq - OEAD - Financial assistance
AMAZON-SrDGT aims to develop and apply an innovative high-resolution approach for quantifying strontium (Sr) isotopes and trace element fluxes in the Amazon River. The methodology integrates passive sampling using DGT (Diffusive Gradients in Thin Films) with high-precision mass spectrometry, enabling the assessment of labile fractions and element fluxes under environmentally relevant conditions—representing a significant advance in monitoring complex aquatic systems.
Determination, fractionation, and speciation of rare earth elements (REEs) in Brazilian Amazon rivers: understanding the biogeochemical behavior of REEs in Rio Negro, Solimões and Amazon basins
2023 - Atual
Fundação de Amparo à Pesquisa do Estado de SP - Auxílio financeiro.
This project aims to advance on the speciation and chemical fractionation of REEs in the Amazon basin to enhance understanding of natural biogeochemical processes and contamination risks in the region. Specifically tailored analytical methods based on DGT and sp-ICP-MS will be developed for the region. The research will encompass different aquatic systems, such as the Negro and Solimões rivers, with a focus on REE behavior at the confluence point (meeting of rivers - the Amazon River). Additionally, it will examine potential impacts of industrial activities in Manaus on the Rio Negro. The study aims to contribute to understanding element cycles and associated threats in the Amazon basin.As an international endeavor, the project will involve collaborations between researchers from the Amazon Research Institute, Federal University of Minas Gerais, Queen's University Belfast (UK), and Montanuniversität Leoben (Áustria).

Development and implementation of methodologies based on the Diffusive Gradients in Thin Films (DGT) technique for in situ multielement determination: Offshore applications.

Petróleo Brasileiro - Rio de Janeiro - CENPES- PETROBRAS - Financial assistance
The main objective of this project is the development and implementation of analytical methodologies based on the Diffusive Gradients in Thin Films (DGT) technique for in situ assessment of the lability and bioavailability of the elements As, Ba, Cd, Cr, Cu, Fe, Hg, Mn, Ni, Pb, V, and Zn in areas of interest within the Representative Platforms Monitoring Project (PMPR). With the development of these methodologies, information related to the lability and bioavailability of these elements in the monitored environments can be made available, which may be extremely important for disentangling potential environmental impacts previously associated (based on conventional analyses) with production and exploration activities in the Oil and Gas Sector.
