About this listen

In this episode I speak with Delina Lyon, Science Executive for Environment at Concawe.

Del and I dive deep into the regulatory assessment of complex substances. This issue still presents a wicked challenge for industry and regulators alike, and Concawe's work is right at the forefront of this.

Our conversation covers:

  • What is Concawe?
  • Del's role at Concawe
  • Environmental assessment of petroleum substances under REACH
  • Del's early career and switch from academia to industry
  • Reflections on the science-policy interface
  • Developments in regulatory testing and assessment
  • Conflicts of interest and the role of industry scientists
  • The wicked problem of complex substances (UVCBs)
  • Challenges with biodegradation testing
  • Weight of evidence and the Persistence Assessment Tool (PAT)
  • The hydrocarbon block method and related tools PETROTOX and PETRORISK
  • Persistence, bioaccumulation and toxicity (PBT) assessments and the new PMT concept
