The Analytica model file contains the actual calculations for this assessment. The actual code created with the ana-wiki converter can be found from [1].

This project is planned to serve as a case study to represent the utilization of the open assessment method.


Scope

Purpose

This assessment evaluates the effects of methyl mercury and omega-3 fatty acids on development of IQ in children. The source of exposure is Finnish fish consumption.

Boundaries

  • Population of Finland
  • Current situation

Scenarios

  • Business as usual (the current situation).
  • Total fish consumption is above the median.
  • Total fish consumption is below the median.

D↷

Intended users

  • Authorities giving food recommendations.
  • Anyone interested.

Exposure variables

Population characteristics

Exposure-response functions

Indices

  • Fish (species): Herring, Vendace, Whitefish, Pike, Perch, Salmon, Pike-pearch
  • Water (from which the fish comes from): Baltic Sea, Inland lake
  • NOTE!
    • Herring is only from the Baltic Sea.
    • All pike-pearch is shown as "Inland lake" although a part comes from the Baltic Sea.
    • All salmon is shown as "Inland lake" although most of it comes from the Atlantic Ocean from Norway.

Analyses

  • What should be done to the total fish intake to keep the net effect of fish on the child's IQ positive?
  • For the scenarios "total fish above median" and "total fish below median", what is the VOI for different variables?
