characterize the reference substances and the reference area in study. Output data
will indicate which model could give the needed results, i.e., which model can
provide a solution to the problem. Figure 4.14 shows a view of the results that the
two models have in common, consisting of concentrations and some daily human
doses. The risk is evaluated in a different way for the two models. The exclusive
outputs of each model reflect the different approaches and areas of use for which it
is designed. With 61 exclusive outcomes, EUSES offers almost twice as many results
as CalTOX with its 34 exclusive outputs.
Further advantages and disadvantages of EUSES and CalTOX are presented.
Beneficially, CalTOX as an Excel spreadsheet offers dynamic data exchange (DDE)
and many data import and export formats enabling comfortable further processing
(e.g., graphical visualization or uncertainty/sensitivity analysis) of its results. A good
range of substances can be assessed with CalTOX, but the variety of output data as
well as spatial and time flexibility and assessable endpoints are less comprehensive
compared to those of EUSES. Perhaps the best resources of EUSES are its great
amount of output data, assessable endpoints (environment and humans) and spatial
