Session Abstract
Most of the current regulations do not require data on toxicokinetics for the risk assessment of chemicals, while there are clear examples of how the risk assessment would benefit from such information, e.g., for a better understanding of the dose-response relationship, of the mode of action, for interspecies extrapolation and/or for route-to-route extrapolation. Moreover, when transferring from animal testing to alternative methods, toxicokinetic information becomes more and more essential, e.g., to guide the design of in vitro toxicity tests (e.g., on exposure conditions) or to extrapolate in vitro concentration-response relationships to in vivo dose-response relationships. This symposium aims to show the advantage of toxicokinetic information for human health risk assessment. First, a general introduction will be given followed by a presentation on incorporation of toxicokinetics in in vivo repeated dose toxicity studies. The third presentation addresses the use of kinetics when moving towards toxicity testing based on alternatives to animal tests. The last two presentations aim to present important recent developments on how kinetic parameters can be collected and used based on the organ-on-chip technology. Organ-on-a-chip technology holds great promise for an integrated analysis of the toxicokinetics and toxicodynamics of chemicals without animal testing.
