Start of the Master’s Module “Evolutionary Ecology and Environmental Toxicology”

02. June 2020

After months of very much reduced research and teaching activities due to COVID-19 we can happily announce that on June 2nd our first Master's module of our new department took off. Even though the hygiene-requirements and the move to virtual teaching made it truly a big challenge for all the of us who are involved in teaching we can call this a huge success. Just recently, last Monday the practical course started which will introduce the students to a theoretical risk assessment scenario including live demonstrations of various effect-based methods, a roleplay between stakeholders, scientists and regulators and interview training, as well as a small field sampling trip all accompanied with a short introductory film-course. Starting from June 29th PD Dr. Werner Brack, who recently got his habilitation recognized by the Goethe University (see below), will take over the course for a virtual demonstration of the Helmholtzcentre for Environmental Research (UFZ). Even though, not one of the excursions and visits to the UFZ in Leipzig and to the black forest is possible this year as we planned it at first place, we hope to offer the students as much of an exciting teaching and learning experience as possible. At this point we want to thank everybody who is involved in the plannings and conduction of this course, you're doing a great job

Congratulations to Sarah for the successful defence of her PhD

Umhabilitierung von PD Dr. Werner Brack

24. Mai 2020

Impressionen von einer virtuellen Antrittsvorlesung im Fach Ökologie über das Thema „Monitoring und Diagnose komplexer chemischer Mischungen im Wasserkörper - Lösungsorientierte Ansätze für ein besseres Wasserqualitätsmanagement“
PD Dr. Werner Brack war schon an der RWTH Aachen ein fester Teil der Lehre im Masterstudiengang „Ökotoxikologie“ und nach Prof. Henner Hollerts Ruf an die Goethe-Universität wechselte er seine Lehrberechtigung ebenfalls an dieselbige. Als sogenannte „Geister-Vorlesung“ im Hörsaal vor leeren Rängen hielt Werner aufgrund der Hygiene-Vorschriften seine Antrittsvorlesung, die aber selbstverständlich live als online-Stream verfolgt werden konnte. Trotz mittlerweile abgeschwächter Hygiene-Auflagen war eine ordentliche Feier natürlich nicht möglich aber unter Einhaltung des erforderlichen Abstands konnten wir ihm dennoch zur sehr gelungenen Vorlesung und seinem neuen Lehrauftrag hier an der Goethe-Universität beglückwünschen. Wir freuen uns auf alle zukünftigen, spannenden Lehrveranstaltungen und gemeinsame Forschungsvorhaben!

Official habilitation recognition of PD Dr. Werner Brack

24. Mai 2020

Impressions of a virtual inaugural lecture in ecology about “Monitoring and diagnosis of complex chemical mixtures in aquatic environments: Solution-oriented approaches for a better water quality management"
PD Dr. Werner Brack was already deeply involved in the teaching activities of the Master's program “Ecotoxicology" at the RWTH-Aachen University and now recently changed his habilitation to the Goethe University in Frankfurt am Main as Prof. Henner Hollert moved with his group. His inaugural lecture was held as a socalled “Ghost-Lecture" in an empty lecture hall and could be watched as an online-live-stream. Despite the already lesser strict hygiene requirements a big celebration was not possible. Nevertheless, in a well-distanced manner we had the chance to compliment Werner on the well-done ecture and congratulate him to his new position. We are truly looking forward to exciting teaching and joint research opportunities in the future!

“Potential and challenge: Biomarker response analyses in Environmental Risk Assessment – Case studies with fish, within the Solutions Project"
Björn worked within the EU Project SOLUTIONS which aimed to develop effect-based tools to be implemented into the monitoring program of European surface water bodies. To assess the realistic application of several in vivo biomarker responses Björn joined the 2013 Joint Danube Survey 3 and an expedition of the research vessel Meteor at the North Sea. We congratulate Dr. Björn Deutschmann to his big achievement and thank him truly for his service and support for the department during his time as a PhD student in Aachen and wish him all the best for his future.

Sentinel: Adverse effects of pesticide pollution on human health

28. February 2020

Based on results from our joint DFG project Sentinel we published recently a joint paper with colleages from the UFZ in Leipzig and the icipe in Narobi, Kenya in Scientic reports. We show that pesticide pollution is a major driver in increasing the occurrence of host snails and thus the risk of schistosomiasis transmission. The study shows for the first time that in the field, pesticide concentrations considered “safe" in environmental risk assessment have indirect effects on human health. Thus we conclude there is a need for rethinking the environmental risk of low pesticide concentrations and of integrating agricultural mitigation measures in the control of schistosomiasis.
