The first publication with data from the new GC-IRMS could now be published together with our Finnish colleagues (see article "Tracing the fate of microplastic carbon in the aquatic food web by compound-specific isotope analysis" in NATURE Scientific Reports). Using isotope markings, it was found that microplastics in water become an integral part of cell membranes in animals through microbial processing.
Gabriele Weigelhofer gave a lecture about "Comparing headwaters' and floodplains' nutrient and organic matter cycling" at the Boku on 16 Dez 2019 and has been recommended for habilitation.

In November 2019 Magdalena Senitza finished successfully her MSc-thesis with the title "Effects of desiccation on heterotrophic microorganisms in benthic sediments in intermittent streams" under Supervision from Gabriele Weigelhofer (AG BIGER).
During her Master thesis, which won now the "Wissenschaf[f]t Zukunft" Award 2019 from NÖ Forschungs- und Bildungsges.m.b.H., Lena Campostrini worked with experimental flumes at WasserCluster Lunz to study the effects of increasing inputs of dissolved organic material (DOM) in aquatic ecosystems.
On the one hand, the award-winning project aimed to investigate the influence of agriculture on the quantity and quality of dissolved organic carbon in rivers, and on the other hand to show the effects of these inputs on aquatic carbon cycles in river ecosystems based on microbial biofilms.

About 200 guests visited WasserCluster Lunz on October 12 at the Open Day 2019 and experienced research first-hand. During talks, the interested visitors could learn more about topics such as the changes in Lake Lunz in times of climate change, the experimental water research on WasserCluster Lunz or the effects of algae on our brain. In addition, guided tours gave visitors insights into various laboratories and because of several hands-on station including a riddle rally for children visitors were enabled to become active themselves.
We thank all visitors for their interest and are pleased to keep them informed in due time by newsletters and articles on our website until the next open day.
On 27. September 2019, the "Forschungsfest Niederösterreich" took place at the Palais Niederösterreich in Vienna. Members of the Workinggroup LIPTOX informed numerous visitors about there research, especially about the question Water-Fish-Human: can human beeings count in future on healthy fish from save aquatic systems?.

An international group of researchers conducted an experiment on the sound of flowing waters in the Lunzer Rinnen Experimental Flumes in July and August. The experiment investigated whether underwater sound recordings can be used to quantify the gas exchange (oxygen, CO2) of turbulent mountain streams with the atmosphere. The project was funded by the AQUACOSM EU-project and led by Dr. Marcus Klaus, Umeå University, Sweden and the WCL working group EcoCatch.
