Viewers refer to graphical figures and tabular files.

All modules potentially have viewers associated with them.

Right-Click Viewers: Specific to a particular module

Icon-based Viewers: Drag-and-Drop icon viewers are usually linked to multiple icons.

Many viewers use COTS software (e.g., Excel spreadsheets or GNU).

The user has the choice of providing their own viewer, using DICtionaries.

Viewers that are most often usedViewers that are most often usedViewers that are most often usedViewers that are most often usedTime Varying “Graphical View” or “Probability of Exeedence”

SCF – Soil Concentration File WCF – Water Concentration File WFF – Water Flux File ATO – Air Transport Output (concentration or deposition rates) AFF – Air Flux File (flux to air) EPF – Exposure Pathway File (concentration in “food”) RIF – Receptor Intake File (intake rate or concentration) HIF – Health Impacts File (dose, risk, hazard)

Time Varying “Graphical View” – Concentration or flux, as it varies in time

“Probability of Exeedence” Probability that a dependent parameter will be equaled or exceeded over the duration

of interest Many times this used to investigate how prevalent the results exceed a standard.

The results can be viewed by• module• Location• Age (cohort)• Constituent• Measure (risk, dose, hazard)• Unit (carcinogen, non-carcinogen)• Route (ingestion, inhalation, etc.)• Pathway (water, soil, air, etc.)• Organ• Summation of ALL in many categories

Dependent and Independent Parameter Datasets

Plotting Criteria• Use of non zero values (Avoids statistical skew in modelingresults due to zero-laden tails)• Confidence Intervals (not used much)• Number of points plotted in figure

After the user chooses viewer under General Info, but data from multiple modules are required for the viewer to successfully run, the system will automatically connect additional modules when the user exits General Info for certain viewers.

The “Stop Lights” go from Red to Yellow, after the viewer is run.

Values associated with the Central Tendency (CT) and Reasonable Maximum Exposure (RME) are designated by the user; therefore, the user needs to ensure that any values used actually represent a CT or RME.
