Abstract

The inorganic chemical analysis of tree rings and speleothems may enable to achieve evidences of extreme floods in the past, since such events contribute to the variation of the elemental composition of these materials. The main goal of this research is the development of analytical strategies for i) acquisition of qualitative data along of tree rings profiles and/or speleothems; ii) elemental bioimaging through the qualitative spatial elemental distribution in such samples employing laser ablation coupled to inductively coupled plasma mass spectrometry (LA-ICP-MS). This development is hampered by factors such as matrix and transport effects, and polyatomic interference. These aspects will be evaluated in the proposed study, with special emphasis on optimization of plasma operating conditions and ablation process, investigation of internal standardization (natural or synthetic) and use of collision and reaction cells to overcome isobaric interferences. The development of methods for the analysis of tree rings and speleothems will support the understanding of natural processes over time in the Peruaçu Canyon region and inside caves found along the river.
