During the two days, the course will address the following topics:

  • UVCB Overview
  • Analytical Characterisation
  • Constituent Selection and Variability
  • Handling variability and compositional uncertainty in UVCBs
  • Environmental Fate Assessment
  • Ecotoxicity Assessment
  • Assessment Approaches
  • Integration of metabolomic approaches
  • Case studies & practical recommendations for a defensible UVCB dossier.
