Uncovering chemical biodegradation in the environment - Kathrin Fenner, Eawag

In this episode I speak with Prof. Kathrin Fenner, one of the leading academic scientists in the study of chemical biodegradation and environmental persistence.

Kathrin and I have a far-reaching conversation covering her background and research interests, challenges and developments in chemical biodegradation research, and implications for policy and society.

We have learned an enormous amount about the fate and persistence of chemicals in recent years, and the work of Kathrin and her group has been at the heart of this.

Listen to the episode to find out about biodegradation of chemicals in different environmental settings, what factors contribute to persistence, understanding transformation products and pathways, predicting biodegradation for different chemicals and scenarios, and how we can utilise this knowledge toward safer and more sustainable use of chemicals.
