The context screen lets you select which contaminant(s) is relevant for your study. If your study includes exposure through ingestion of food, this is also where you select which types of food you have concentration data for. Finally, if you are interested in calculating exposure of more than a single individual, you can define which individuals to model here.
On the right hand side of this screen is
The context screen is located after the model screen, as the model components determine which contaminants are available, or if food is a relevant dependency.
The Available list shows all the contaminants for which there are (or might be) default parameter values. Select a contaminant in the list to include it in your study. If the contaminant you are studying is not in the list, you can add a new contaminant by clicking the Add button.
When you add a human intake model, this tab allows you to specify which food/ingestibles is/are relevant for your study. The list displays a list of ingestibles which can be modelled by the software. If you have included a model for Soil, and want to include the exposure pathway “ingestion of soil”, you must select Soil in this list.
If you want to include exposure through ingestion of food which is external to the investigated region, click the Add button. Select an external ingestion source and click Remove to remove it.
If you have added the body model or the human intake models for populations, this is where you specify which different individuals or groups of people you need to investigate.
Click Add to add a single individual, Add many… to generate a list of individuals (useful if your study includes many individuals). The Remove button, like expected, removes an individual.
To set up scenarios, click the Scenario button on the right hand side of the screen.
New scenarios can be defined by either clicking the Add button or by right-clicking the window and selecting Create from the menu. You can also select which objects depend on scenario by clicking the Select button.
Each item (row) in the table details one scenario. The table can be sorted on a specific property by clicking it's column.
To display the menu, right click anywhere inside the window.
