In today's world, Atomic Spectroscopy as a fundamental part of Analytical Chemistry contributes more than ever to addressing the global challenges we face, by supporting the realization of the United Nations Sustainable Development Goals (SDGs), including fostering Green transformation. Basic research in the field of atomic spectroscopy in elemental and isotopic analysis (especially focusing on inductively coupled plasma - mass spectrometry (ICP-MS) is (still) fundamental. In this talk, different projects spanning from recycling to environmental research questions as motivation behind, the potential of ICP-MS along with the challenges of sample preparation will be given.
Key projects include MetroCycleEU (EMPIR-EURAMET) aiming at developing SI-traceable methods for quantifying technology-critical elements (TCE) in urban mine waste, and TecEUS as well as MURmap, applying advanced ICP-MS/MS techniques to assess TCE exposure in urban environments. In all three projects projects associated with very different stages along the life cycle of TCEs, analytical methods are developed to push the limits of inductively coupled plasma tandem mass spectrometry (ICP-MS/MS) by focusing on using alternative reaction/collision gases to overcome interferences and pushing limits of detection in challenging matrices. The challenges and achievements in ICP-MS/MS analysis will be presented on the example of both projects.
Finally, the MetroPOEM project (EMPIR-EURAMET), focuses on developing sensitive techniques for detecting low pollutant levels and determining their isotope ratios. The outcomes of MetroPOEM are expected to significantly enhance environmental monitoring and assessment, providing tools for effective pollution reduction strategies and health protection. Specifically challenging are the low levels of selected analytes (such as Pb, Ni as well as Sr-90) in the seawater matrix under investigation. Sample preconcentration and passive sampling techniques are fundamental for their accurate determination. The potential of in-situ assessment of trace elements and isotopic variations in aqueous environments using diffusive gradients in thin films (DGT) is demonstrated. Collectively, these projects underscore the vital role of atomic spectroscopy in the green transformation, bridging fundamental science with industrial advancements, and contributing significantly to environmental sustainability.
