Multimedia fate modelling - the NanoFASE soil-water model

The NanoFASE soil-water model predicts the fate and bio-uptake, across space and in time, of nanomaterials entering the soil and aquatic environments. It works by coupling submodels for environmental compartments such as soils, rivers, bed sediments, lakes, estuaries and the sea, and simulating the transport between these compartments of nanomaterials in different forms and states. Within each compartment, nanomaterials can transform between different forms and states, and be taken up by the biota present.

An example of the gridded structure of the NanoFASE soil-water model. The model uses a grid to locate specific environmental compartments. Grids can represent ’land’ or ’sea’. Land grid cells contain soil (green) and estuary or freshwater (dark blue). Sea grid cells contain only sea (light blue). The diagrams on the right show possible layouts of river reaches and lakes within a land grid cell.

The NanoFASE model must be coupled to a model or models of nanomaterial source(s), concerning inputs of nanomaterials either to soils or directly into surface waters.

The model can also be coupled to the atmospheric deposition model to simulate the fate of nanomaterials which were emitted to the atmosphere  and subsequently deposited to the land or water surface.
