WebIn physiologically based toxicokinetic models, the body is represented as a series of mass balance equations that describe each organ or tissue on the basis of physiologic considerations. There is no inherent contradiction between the classic and physiologically based approaches, yet certain assumptions differ between the two models. WebSep 26, 2024 · Toxicokinetic-Toxicodynamic Models. TK-TD models combine dose–time relationships of toxicokinetics (TK) with concentration–activity relationships of TD and allow a holistic view of dose-dependent toxic effects over time. TK-TD models are therefore particularly well suited to represent causal relationships between exposure and the toxic ...
