Schematic representation of the Lemna model presented in Schmitt et al. (2013). External factors affecting chemical uptake or growth are given in blue and the different rate constants affecting biomass growth of the plants (green) are given with grey arrows. The growth model is described in Section 6.2.1.1. The flow and effect of the toxic substance is given by black arrows and the TK‐compartment by an orange box. The TK model is described in Section 6.2.1.2 and the TD model in Section 6.2.1.3, respectively
