2-FUN

2-FUN (Full-chain and UNcertainty Approaches for Assessing Health Risks in Future ENvironmental Scenarios) is an Integrated Project funded at the level of 1.6 Million € by the European Union 6th Framework Programme (thematic priority 6.3 "Global Change and Ecosystems", contract n° FP6-2005-GLOBAL-4-036976). Duration: Feb 2007 - Jan 2011. Read Project Summary

2-FUN Multimedia Modelling Tool

The 2-FUN Multimedia Modelling Tool allows the user to run simulations and to conduct risk assessments of the multimedia models developed within WP2 (Realistic and homogeneous multimedia exposure models covering the European diversity and uncertainty analysis). The tool is based on the simulation modelling tool Ecolego.
Each of models developed in WP2 represents a specific type of environment. Each model has been implemented as a stand-alone module that contains the parameters, time dependent data and equations specific to the model.
The software contains a library of modules which can be connected for building a model for a specific scenario. The following modules are available:

Risk assessments can be carried out for several contaminants. Default parameter values are currently available for Lead and PaP.
The tool supports both deterministic and probabilistic (Monte-Carlo) simulations, as well as sensitivity analysis of the model parameters.
The 2-FUN multimedia software consists of a sequence of pages, that allows the user to:

  1. Describe the assessment and select which contaminants are involved.
  2. Assemble a model for the scenario by combining modules from the library. This page also lets the user review the structure of the model components and equations in a browser-like fashion. 
  3. Input parameter data and/or assign probability density functions, e.g. geometrical properties, soil and plant properties etc. 
  4. Input time dependent input data such as precipitation, concentrations, solar radiation etc.
  5. Run a deterministic or Monte Carlo simulation. Specifying simulation properties such as start and end time and number of simulations.
  6. Create different types of plots of the simulation outputs, as well as plots for sensitivity analysis.
  7. Create tables of the simulation outputs and sensitivity indices.
  8. Generate a report for the assessment, which contains a full model description, all parameters and time-dependent data as well as charts and tables created on previous pages.
