TOXFATE: Contaminant Fate Model

The Contaminant Fate Model TOXFATE simulates the behaviour of one of more pollutant within a completely mixed lake and determines the toxic accumulation in water, phytoplancton, zooplancton, fishes, sediments and benthos. It uses information both on the chemical properties of the pollutant itself and on the local environmental conditions, such as water circulation, mean wind velocity, concentration of suspended solids.
From a mathematical point of view, the model is represented by a set of parametric differential equations, that can represent several pollutants in a lake, a single pollutant in several lakes or any mixture of the two.
