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 Mackay
• The concept of environmental persistence
• Tools for chemicals management and the evolving policy landscape
• Exposure assessment and risk assessment - the importance of considering exposure in addressing chemical risks
• How sustainability is changing the way we look at chemicals
• How science is produced, and communicated in the media
• How well do our tools fit what is happening in the environment?
• Biodiversity and the roles of chemical and non-chemical stressors
• Changes to policy around persistence - storing up problems for the future?
• Why biodegradability is important for consumer-facing sectors
• Persistence in the discussion on product circularity and innovation
• What's at stake? Balancing costs to society
• The need for multidisciplinary expertise and the role of industry
