TecEUS project inside a children’s booklet about the cycle of the plant in the city

Plant workshop - Children's University 2020

At this year's Children's University 2020 Vienna (kinderuni.online), the participating children were able to take a closer look at the plant's cycle. A booklet about “Hanna the hen - and her journey through the city” showed the advantages of urban greenery and why it is so important to have plants in the city. What is the cycle of the plant? How does it work in the city? And what are the advantages of plants in the city, especially in terms of heat regulation, rainwater management and air quality? The booklet gives an insight into the latest research at the university. This raises the question of whether there are differences in air quality between the city and a green courtyard, and whether plants can act as a biofilter for pollutants in the air, especially for technologically critical elements. In the booklet, the TecEUS project is linked to current research on the topic. The brochure was created and designed by DI Pia Minixhofer and DI Philipp Spörl from the Institute of Soil Bioengineering and Landscape Construction (IBLB). It shows why natural cycles are so important for the (urban) environment. If you are interested in the booklet for children (6-10 years), please feel free to contact the authors.

The FWF stand-alone project "TecEUS - Technology-critical Elements in Urban Spheres" under the PI Johanna Irrgeher started with 01.04.2020 in his three-year project duration. The project team, made up of partners from the Montanuniversität Leoben, the University of Natural Resources and Life Sciences, Vienna and the Medical University of Vienna, met for a virtual kick-off meeting. The team was happy about the official start of the project, albeit differently than expected.

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.


First Team Meeting at BOKU/Tulln-Project Brainstorming

Back in April 2017, today's project team initiated the idea of a transdisciplinary joint project aiming at the investigation of technology-critical elements in urban spheres. Therefore, we met at the BOKU in Tulln and took the opportunity to visit the cleanlabs for trace element and isotope ratio analysis at the Institute of Analytical Chemistry.
