Data 1
Data 1 is expressed as µg/kg bw/year (or mg/kg bw/d?).
⇤--1: . Data 1 should not be used, because there is ambiguity about the units. --Jouni 14:44, 16 September 2009 (EEST) (type: truth; paradigms: science: attack)
<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
Data 2 represents daily intake of methyl mercury by Finnish pregnant women and adults aged 18-55yr and 55yr+ due to fish consumption. The MeHg intakes from sea and freshwater 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 daily consumption of this species by target population subgroup divided by the body weight in this subgroup.
| Fish species | Mean MeHg intake by pregnant women |
| Baltic Herring | 9.6058e-004 |
| Vendace(inland) | 7.1172e-004 |
| Vendace(sea) | 2.9655e-005 |
| Whitefish(inland) | 1.1148e-003 |
| Whitefish(sea) | 7.1276e-004 |
| Pike(inland) | 4.9823e-003 |
| Pike(sea) | 1.2235e-003 |
| Perch(inland) | 6.169e-004 |
| Perch(sea) | 5.8318e-004 |
| Atlantic Salmon | 1.2333e-003 |
| Pike-perch(inland) | 0 |
| Pike-perch(sea) | 0 |
| Total fish | 0.012169 |
Dependencies
List of parents:
- Mercury and methyl mercury concentrations in fish
- Domestic fish consumption of the general population in Finland
- Domestic fish consumption of the pregnant women in Finland
- Body weight in Finland
Unit
µg/kg bw/d
Formula
MeHg_Concentration_species(i)*Daily_consumption_species(i)/BW
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 the risk of CVD mortality in adults.
Result
Note! At the moment the results only apply to Finnish pregnant women.
