One-compartment kinetics
One-compartment kinetics for a chemical compound specifies that the uptake in the compartment is proportional to the concentration outside the compartment, and the elimination is proportional to the concentration inside the compartment. Both the compartment and the environment outside the compartment are considered to be homogeneous.The compartment typically represents some organism.
This model is used in the simplest versions of the DEBtox method for the quantification of effects of toxicants.
