Model components

Model components

Compartment

Flow

Part of the system with defined boundaries which can store the quantity of interest (e.g. a pesticide)

Represents the movement of the quantity from one compartment to another

Parent in soil

Metabolite in soil

Parent  Metabolite

Change of quantity in compartment with time

dCompartment / dt = + Flows in - Flows out

Variable

Quantity which is a function of other model components or a function of an independent variable (e.g. time)

DT50 as a function of other model parameters


Initial conditions and parameters

Initial conditions and parameters

For each compartment, the starting point (quantity present at the beginning of the simulation) must be defined

Parent: 100% applied radioactivity

Metabolite: zero

Parameters are constants which do not change

during the simulation

kparentdegradation rate constant for the parent in soil

M0 initial amount of the parent compound

ffM formation fraction
