Biomarker toxicodynamics linked to BPA toxicokinetics in three-spined stickleback: a PBPK-TD model
International audience Bisphenol A (BPA) is considered a substance of very serious concern due toits endocrine disruptor function, high production volume, and persistence in the aquaticenvironment. In this context, physiologically-based toxicokinetic models coupled withtoxicodynamics (PBTK-TD) have...
