Training course content
As recently emphasised by EFSA, toxicokinetictoxicodynamic (TKTD) models are of particular interest for regulatory risk assessment of pesticides for aquatic organisms. TKTD models can encompass a large set of mechanisms describing the compound kinetics inside organisms as well as their effect at the individual level. Compared to classical dose-response models, TKTD approaches have many advantages: Accounting for temporal aspects of exposure and toxicity, considering data points all along the experiments and not only at the end, and making predictions for untested situations such as realistic field exposure scenarios (e.g., time-variable pulsed exposure profiles).
The General Unified Threshold model of Survival (GUTS) is within the most recent and innovative TKTD framework to deal with survival toxicity test data but is still underused in practice due to specialist programming and statistical skills that are necessary to run models in practice. This training course aims at presenting the theory of GUTS models and at introducing the participants with dedicated tools allowing the practical use of GUTS models.
