Concentrations settings¶
Selection settings¶
| Name | Description |
|---|---|
Concentrations tier |
Specifies the concentration data should be treated according to a pre-defined tier or custom. |
Use substance conversions |
If true, 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 true, all allocated substances kept after substance conversion, if false, 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 substrance conversions. |
Use extrapolation rules |
Use extrapolation rules. |
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 for the five most toxic substances 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 authorised uses |
Restrict water imputation to authorised uses. |
