    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.  Works cited: Innovate beyond PFAS | Science Designing Small Molecules for Biodegradability | Chemical Reviews Bridging across OECD 308 and 309 Data in Search of a Robust Biotransformation Indicator | Environmental Science & Technology Developing a weight-of-evidence methodology for persistence assessment of substances in the environment | IEAM Breaking it down: Unveiling the roles of chemical structure, concentrations and technology on micropollutant biotransformation in wastewater treatment plants - ScienceDirect High-Throughput Miniaturized Biotransformation Testing Using Activated Sludge Enables Rapid Chemical Persistence Assessment | Environmental Science & Technology Letters Read-Across of Biotransformation Potential between Activated Sludge and the Terrestrial Environment: Toward Making It Practical and Plausible | ES&T Modernizing persistence–bioaccumulation–toxicity (PBT) assessment with high throughput animal-free methods | Archives of Toxicology Do biotransformation data from laboratory experiments reflect micropollutant degradation in a large river basin? - ScienceDirect Eawag-Soil in enviPath: a new resource for exploring regulatory pesticide soil biodegradation pathways and half-life data - Environmental Science: Processes & Impacts FAIR and Effective Communication of Data on Chemical Contaminant Biotransformation in the Environment | ES&T Letters Confidently Uncertain: Probabilistic Machine Learning to Predict Soil Biotransformation Half-Lives | ES&T Predicting Micropollutant Removal in Wastewater Treatment Based on Molecular Structure: Benchmark Data and Models | ES&T Persistence Assessment of Chemicals: Trajectories toward New Approach Methodologies (P-NAMs) | ES&T Discover enviPath.org Support the show

    Chemicals in our language - Joanna Gavins, University of Sheffield

    In this episode I speak with Joanna Gavins, who is a professor of English Language and Literature at the University of Sheffield. Joanna and I discuss the language we use and how this influences the way we think, feel and act in relation to choices we make, the environment, and chemicals.  We start off by discussing the work Joanna has been doing at the Bio-based and Biodegradable Industries Association (BBIA) on how to effectively communicate information about sustainability to consumers. We also delve into our complex relationship with nature, and how this is influenced by language. Our conversation then moves onto chemicals. We do a deep dive into the language surrounding chemicals in modern discourse, and how this influences public perception and emerging policy. We talk about the issue of chemicals in the environment, how this relates to us, and how we might get better at talking - and thinking - about these issues. I hope you will find this discussion as fascinating as I did!

    Getting a grip on environmental persistence – Irene Bramke, AstraZeneca

    What happens to the chemicals we use in everyday life once they enter the environment? In this episode, I am joined by Dr. Irene Bramke, Senior Environmental Risk Assessor at AstraZeneca.  Irene and I have a detailed discussion about persistence (how long it takes for chemicals to break down in the environment). With recent concerns around plastic pollution, PFAS 'forever chemicals', and broader sustainability goals, the persistence of chemicals in the environment has become one of the most urgent and pressing issues for policymakers and society. Irene and I discuss the science behind persistence, and how it relates to the risks chemicals might pose to people and the environment. We also talk about recent regulatory developments in Europe, and how these are reshaping the future of chemicals management.  Our conversation covers: Irene's background and career journeyGrappling with complexity - insights from studying soils in an agrochemicals companyIndustry's participation in regulatory science - then vs nowIssues of environmental relevance in laboratory biodegradation testingThe evolving policy landscape for persistenceNon-degradable chemicals and the legacy P/vP criteriaIn the eye of the beholder - the meaning of word 'persistent'Implications of new policies - the PMT/vPvM hazard classesA troubling outlook - data gaps, transformation products, and questionable impact assessments?Reflections on OECD simulation tests as tools for persistence assessmentsInsights from AstraZeneca's Ecopharmacovigilance programmeThe importance of data quality in monitoring efforts - the CREED approachShifting regulatory paradigms - hazard assessment vs risk assessment, and the need for continuing dialogueCan we get better at assessing persistence?
