The project TecEUS aims to assess the release, exposure and accumulation of selected technology critical elements (TCE) (Ga, Ge, In, Tl, Y, Nb, Ta, Te; platinum group elements (PGE) and rare earth elements (REE) along with technology-metals (Li, Be) in an urban environment. This is accomplished by applying advanced analytical techniques based on inductively coupled plasma mass spectrometry (ICP-MS) in combination with models for material flow analysis. These elements used in novel technologies are increasingly released into the environment and substantial knowledge is missing with regards to quantities, environmental cycles and potential health hazards. One major motivation in the context of Green Public Health is to explore systematically the role of urban greening related to these elements dissipated into an urban sphere on the example of major cities such as Vienna (Austria).
i. the accurate assessment of elemental and isotopic data from TCE in environmental samples;
ii. the extent of the accumulation of TCEs and related elements in urban spheres (water, plants, soil) and understanding their sources, pathways and sinks on the example of a major urban sphere;
iii. the effectiveness of urban green façades as filters for TCEs and their potential as human health preventive measure;
iv. a system-wide assessment linking dynamics of in-use technologies, to flows of specific TCEs and their leaching and dissipation from use-phases across Vienna.
v. emerging human health threats due to increasing TCEs levels in air and urban agricultural products; The key objectives are addressed from multiple scientific perspectives.
