  • Powering progress in chemicals assessment science - Katherine Santizo, Cefic-LRI
    Sep 15 2025

    In this episode I speak with Dr Katherine Santizo, Programme Manager of Cefic's Long-range Research Initiative (LRI).

    Since 1999, Cefic-LRI has funded over 250 projects (totaling approximately €90 million) to advance the scientific assessment of the safety of chemicals, and to improve understanding of potential health and environmental risks.

    Tune in to hear first-hand from Katherine about the exciting work that Cefic-LRI does, and how this is helping to deliver progress in chemicals assessment science.


    Our conversation covers:

    • What is Cefic-LRI? The LRI mission, and what makes it different
    • How it works - the LRI process from ideation to publications
    • Tools and solutions to address key regulatory challenges
    • Katherine's background and career journey
    • Working across disciplines - integrating environmental science with human health
    • Reflecting on the 25 year anniversary of Cefic-LRI
    • Upcoming research projects: new approach methodologies (NAMs), mobility and biodegradation
    • Other hot topics in chemicals safety research
    • Cefic-LRI's contribution to persistence assessment science

  • Serving the regulatory compliance community - Janet Greenwood, TT Environmental
    Aug 6 2025

    In this episode, I speak with Janet Greenwood of TT Environmental.

    Janet has been working for many years in chemicals safety and regulatory compliance, and runs a community of regulatory professionals (the Chemical Regulations Self Help Group) here in the UK, and a regular newsletter (Chemicals Coffee Time) with over 4000 subscribers across the globe.

    Janet therefore brings an important perspective from regulatory professionals and small and medium enterprises (SMEs) working 'on the ground' to address regulatory compliance within the chemicals industry.


    Our conversation covers:

    • Janet's background and the origins of her community and newsletter
    • Chemicals Coffee Time - during lockdown and beyond
    • Janet's journey to becoming an environmental consultant
    • Environmental permits, sustainability and ISO 14001
    • Top-down procedures vs individual vigilance
    • Safety Data Sheets (SDS), CLP labels, and the need to keep the end user in the focus
    • Dealing with the deluge of regulatory changes in the EU and UK
    • The impact of new substances of very high concern (SVHCs)
    • Reflections on the evolution and broader impacts of REACH
    • The shifting chemicals marketplace and shared responsibility
