Benefit-risk assessment on farmed salmon: To the assessment page | To the Analytica model
Decision variables:

Variable:Recommendation for consumption of farmed salmon | Variable:Pollutant concentration limits for fish feed

Indicators:

Variable:Pollutant health risk due to the consumption of salmon | Variable:Net health effects due to the consumption of salmon

Other variables:

Variable:Persistent pollutant concentrations in fish feed | Variable:Persistent pollutant concentrations in salmon | Variable:Salmon intake in the population of the Western Europe | Variable:Exposure to persistent pollutants due to salmon in the population of the Western Europe | Variable:Dose-response function of persistent pollutants | Variable:Omega-3 content in salmon | Variable:Omega-3 intake due to salmon in the population of the Western Europe | Variable:Dose-response function of cardiovascular effects of omega-3 fatty acids | Variable:Total mortality in the Western Europe | Variable:Cardiovascular mortality in the Western Europe | Variable:Cardiovascular effects of omega-3 in salmon in the Western Europe


Scope

Pollutant health risk due to the consumption of salmon describes the health risks of persistent pollutants found in the farmed salmon consumed in the Western Europe (EU-15, Norway, Iceland, and Switzerland). The risk is measured as avoided premature deaths per year (this leads to negative numbers for increased risks).

Definition

Data

  • The plausible range is -10000 - 0 avoided cases per year (author judgement).
  • Pollutant health risk is calculated assuming additivity between the pollutants.
  • Dioxin risks are not considered because they were not considered in Hites' paper[1].

Unit

avoided cases/a

Formula

<anacode>

var a:= -Risk_slope*pollutant_exposure/1000*western_europe;
a:= (if pollutant1='Dioxin' then 0 else a);
sum(a,pollutant1)
