Methyl mercury intake from fish in Beneris
Scope
MeHg intake from fish describes the exposure to methyl mercury due to fish consumption in the Beneris population.
Definition
MeHg intake from fish is represented as a continuous variable and is indexed by variable age. It applies to Finnish pregnant women (this represents prenatal exposure to MeHg from fish), to the two last age categories (18-55yr, 55yr+) and to indicators such as intelligence quotient (IQ) in children and remaining lifetime risk of death from cardiovascular disease in adults.
Causality
List of parents:
- Mercury and methyl mercury concentrations in fish
- Domestic fish consumption of the general population
- Domestic fish consumption of the pregnant women in Finland
- Body weight in Finland
Data
Data 1
Data 2
Data 2 represents intake of methyl mercury by Finnish pregnant women due to fish consumption. The MeHg intakes from sea and freshater species are estimated separately. The MeHg intake from a given fish species is calculated as a product of the MeHg concentration in this species and intake of this species by pregnant women divided by the body weight of pregnant women.
Formula
Data 1
<anacode>Concentrationdata*Subgroupconsumption/365/BW</anacode>
Exposure is calculated as a product of concentration data and fish consumption data. This is further divided by bodyweight to report exposure in relation to kg of bodyweight.
Data 2
General formula:
MeHg_Concentration_species(i)*Intake_species(i)/BW
Unit
Data 1
µg/kg bw/year or mg/kg bw/d?
Data 2
µg/kg bw/d
