====Models library====

The MERLIN-Expo models library is a collection of models that can be used individually, or together, to form the [[mathematical model]] for the study. These models are referred to as [[sub-system|sub-systems]].

[[Sub-system|Sub-systems]] can be connected, so that one [[sub-system]] provides input data for another [[sub-system]].

====Contents====

The library is divided into the following categories:

===Environment===

These are models for the environmental media in which pollution occurs.

  * [[:merlin-expo:models:atmosphere|Atmosphere]]
  * [[:merlin-expo:models:atmosphere_measurements|Atmosphere measurements]]
  * [[:merlin-expo:models:river|River]]
  * [[:merlin-expo:models:river_measurements|River measurements]]
  * [[:merlin-expo:models:soil|Soil]]
  * [[:merlin-expo:models:soil_measurements|Soil measurements]]

===Food===

The food model account for food produced in the investigated region and that is contaminated by the environmental media. All items here no not necessarily end up on a plate - some (such as phytoplankton) are food for fish.

  * Terrestrial food
    * [[MERLIN-Expo:models:Fruit tree]]
    * [[MERLIN-Expo:models:Grain]]
    * [[MERLIN-Expo:models:Leaf]]
    * [[MERLIN-Expo:models:Potato]]
    * [[MERLIN-Expo:models:Root]]
  * Aquatic food
    * [[MERLIN-Expo:models:Fish]]
    * [[MERLIN-Expo:models:Invertebrate]]
    * [[MERLIN-Expo:models:Phytoplankton]]

===Human exposure===

The human exposure models deal with the exposure route to people and the fate of the contaminants in the human body.

  * [[MERLIN-Expo:models:Human intake]]
  * [[MERLIN-Expo:models:Population intake]]
  * [[MERLIN-Expo:models:Man]]
  * [[MERLIN-Expo:models:Population]]

====Updates====

When MERLIN-Expo is launched, the software will search on-line for updates to the library. Updates to the library will not affect [[sub-system|sub-systems]] that have already been added to a [[model]].
