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 interests
- What's wrong with the way we do research on chemicals?
- Endocrine disruption and uncovering population-relevant effects
- Insights from 30 years of monitoring data on macroinvertebrate diversity in English rivers
- The issue of combined sewer overflows
- Why monitoring data is so valuable, and so underappreciated
- Problems with the Water Framework Directive
- Risk assessment of chemicals and the mixture assessment factor (MAF)
- Are we prioritising the wrong things?
- Perverse incentives in research
- Science in the media and improving public discourse
- Advice for early career scientists
