A program of regulatory environmental fate (eFate) studies is required for globally acceptable submissions for agrochemicals, chemicals (REACH regulations) and pharmaceutical risk assessments (human and veterinary). Studies include:

  • Soil degradation
  • Aquatic degradation
  • Sorption, including aged and non-aged leaching
  • Photolysis
  • Hydrolysis

Additionally, bespoke study designs may often be needed to answer specific regulatory objectives (e.g., persistent compounds, volatile test items and fumigants, non-standard isotopes and the marine environment).

This webinar discusses the studies that may be required and the factors that must be considered when designing your eFate program.
