Norfluoxetine Is the Only Metabolite of Fluoxetine in Zebrafish (Danio rerio) Embryos That Accumulates at Environmentally Relevant Exposure Scenarios

Fluoxetine has been recognized as one of the most toxic pharmaceuticals in the aquatic environment. Since there is growing evidence that the toxic potential of fluoxetine in surface waters is markedly influenced by its own metabolism in aquatic species, this study investigated the biotransformation of fluoxetine in the zebrafish embryo – an aquatic model organism of intermediate complexity.

Impact of the antidepressant citalopram on the behaviour of two different life stages of brown trout

Over the last two decades, there has been a constant increase in prescription rates of antidepressants. In parallel, neuroactive pharmaceuticals are making their way into aquatic environments at increasing concentrations. Among the antidepressants detected in the environment citalopram, a selective serotonin reuptake inhibitor, is one of the most commonly found. Given citalopram is specifically designed to alter mood and behaviour in humans, there is growing concern it can adversely affect the behaviour on non-target wildlife

Civil Society and the Governance of Water Services: German Political Parties’ Reactions to Right2Water

The European Citizens’ Initiative (ECI) Right2Water asked for guaranteed water quality and quantity all over Europe, and demanded that water services remain in the hands of public entities. Support for Right2Water was particularly pronounced in Germany. The German organisers managed to collect 16 times more signatures than the minimum necessary to be counted towards the quorum. How have the German political parties reacted to the overwhelming public support for Right2Water?

What determines regulatory preferences? Insights from micropollutants in surface waters

The ever-increasing consumption of pharmaceuticals, cosmetics, detergents and food additives puts aquatic ecosystems under strain. Accordingly, respective regulation of micropollutants in surface waters is an issue that not only needs to include the perspective of public actors and producers but also that of the consumers.

Tail Movements of Zebrafish Embryos for the Evaluation of Neuroactive Substances

Environmental pollutants can interfere with the development of the nervous system of vertebrates. However, the identification of the neurotoxic potential and the actual modes of action of these substances is highly challenging.

Occurrence and Transformation of the Antidiabetic Metformin

The research group Environmental Analytical Chemistry lead by Professor Christian Zwiener (University of Tübingen) reports in their recent publication on new transformation products (TPs) of metformin, a most frequently applied drug worldwide.
