Exemplification Sample Clauses
Exemplification. The author of this chapter is currently working on a global fate and exposure model called GLOBOX that meets the requirements mentioned in the former subsection. The model will be spatially differentiated on the level of separate coun- tries and oceans. Since it is not yet operational, it is not possible to calculate fate and exposure factors with it. The fate and exposure factors for this example could therefore not yet be calculated, and have been left out. The same applies to the characterisation factors. Other area-related parameters should be considered as preliminary values that may be changed in the final model. With respect to environmental transport and degradation equations, the GLOBOX model is largely based on the Dutch model USES 2.0. The parameter requirements of this last model will be used as a basis in this example. The exam- ple refers to three emissions: an emission of sulphur dioxide (SO2) to air, an emis- sion of toluene to water, and an emission of pentachlorophenol (PCP) to soil. These emissions are evaluated in the context of two impact categories: human toxic- ity and acidification. The world is divided into countries and oceans. The example is limited to two countries: Norway and Sweden. Only spatially differentiated pa- rameters are mentioned in the table. For the other parameters, default values are assumed to be included in the model. The goal of this example is to give an over- view of the parameters to be collected in practice (see Step 1-9):
Step 1: Substance parameters
Step 2: Areas for spatial differentiation, with the corresponding fate and exposure parameters Step 3: Fate factors Step 4: Exposure factors
