In this episode I speak with Dr. Steven Brennan, co-founder and CEO of Foresight. Foresight is a software platform that helps organizations to make sense of complex and fast moving chemical regulations, so they can always be ready for what's coming next. Steven and I have a nice conversation that shows how he turned his years of regulatory experience into a software solution that solves a key challenge - how to get access to key insights faster to understand and manage regulatory change.&...
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 t...
In this episode I speak with Dr Katherine Santizo, Programme Manager of Cefic's Long-range Research Initiative (LRI).

Through its range of task forces, events and coordination activities, ECETOC is working across the full spectrum of chemical hazard and risk assessment topics, incl...
In this episode I speak with Andrew Johnson, Environmental Research Scientist at the UK Centre for Ecology & Hydrology and Visiting Professor at Brunel University. Andrew and I have a fascinating discussion about the current state of scientific research and public discourse on chemicals, and how a different approach might ultimately lead to better outcomes for wildlife. Our conversation covers: Andrew's background and research interestsWhat's wrong with the way we do research on...
In this episode I am joined by Todd Gouin of TG Environmental Research. Todd and I have a far-reaching discussion about the science and policy of chemicals in the environment. Our conversation covers: Todd's career journey and the role of Don MackayThe concept of environmental persistenceTools for chemicals management and the evolving policy landscapeExposure assessment and risk assessment - the importance of considering exposure in addressing chemical risksHow sustainability is changin...
In this episode I share an article discussing the new hazard classes under the EU CLP regulation, and what this might mean for chemicals management more broadly. As a reminder, the new CLP hazard classes are: Endocrine disruptors (ED) for human health and the environment;Persistent, bioaccumulative and toxic (PBT); very persistent and very bioaccumulative (vPvB); andPersistent, mobile and toxic (PMT); very persistent and very mobile (vPvM).I also share some insights on what has been hap...
I speak with Gabriel Sigmund, Assistant Professor at Wageningen University and Research, and board member of the International Panel on Chemical Pollution (IPCP). We discuss: Gabriel’s background and research interestsHow the fate of charged organic compounds differs from neutral compoundsThe issue of mobility in the environment and the concern around persistent, mobile and toxic (PMT) substancesComplex interactions controlling sorption and other fate processes in soilThe ongoing importance o...
