Concentrations settings¶
Selection settings¶
| Name | Description |
|---|---|
Concentrations tier |
Specifies the concentration data should be treated according to a pre-defined tier or custom. |
Filter samples exceeding the concentration limits |
If checked, samples with at least one substance concentration higher than some factor (concentration limit filter exceedance factor) times the MRL are filtered out. |
Concentration limit filter exceedance factor |
The multiplication factor for the concentration limit exceedance filter. |
Use substance conversion rules |
If checked, concentrations are modelled in terms of active substances (using substance conversion). |
Substance conversion method |
Allocation method for assigning active substance concentrations from measured substance concentrations based on substance translations. |
Retain all allocated substances after active substance allocation |
If checked, all allocated substances kept after substance conversion. Otherwise, the concentration data is restricted to the active substances of the assessment group. |
Account for substance authorisations in substance conversions |
Account for substance authorisations when allocating measured substances to active substance using substance conversions. |
Use extrapolation rules |
Use extrapolation rules to extrapolate food samples for foods with a limited amount of samples (data poor foods) from other foods (data rich foods). |
Threshold for extrapolation |
Threshold for extrapolation. |
Restrict extrapolations to equal MRLs |
Restrict extrapolations to equal MRLs. |
Restrict extrapolations to authorised uses |
Only extrapolate if substance use is authorised. |
Impute water concentrations |
Impute constant concentration values on the selected (water) commodity. |
Water commodity |
The commodity for which constant concentration values should be added. |
Water concentration value (µg/kg) |
Constant concentration value that should be used for water (in µg/kg). |
Restrict water imputation to the five most toxic substances |
Restrict water imputation to the five most toxic substances. |
Restrict water imputation to authorised uses |
Restrict water imputation to authorised uses. |
Include focal commodity concentrations |
Specifies whether there is monitoring data that should replace part of the consumption data for the specified focal commodities. |
Focal commodity concentrations replacement method |
Replacement method to be used for replacing base concentration data with concentration data of the focal commodity/commodities concentrations. |
Focal commodity substance occurrence percentage |
Anticipated occurrence percentage / agricultural use percentage of the focal commodity. |
Adjustment factor for the focal food/substance concentration |
Optional adjustment factor for the focal food/substance concentration. E.g., the expected ratio of mean monitoring concentration and mean field trial concentration. |
Use deterministic substance conversions for focal commodity |
Convert measured substance concentrations of focal commodity to active substance concentrations using deterministic substance conversion factors. |
