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.

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 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. &nbsp;&nbsp; <br>

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:

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

MeHg_Concentration_species(i)*Intake_species(i)/BW

Unit

Data 1
