- Data tables:
Kinetic conversion factors
Kinetic conversion factors convert external exposures from one or more external routes (dietary, non-dietary oral, dermal, inhalation) to an internal (target) compartment.

Kinetic conversion factors
Kinetic conversion factors translating external (daily) exposures for specific routes to the resulting internal target intakes.
Accepted table names: KineticConversionFactors, KineticConversionFactor.
| Name | Type | Description | Aliases | Required |
|---|---|---|---|---|
idKineticConversionFactor |
AlphaNumeric (50) |
Id of the kinetic conversion factor |
idKineticConversionFactor, idConversionFactor, idKCFactor |
Yes |
idSubstanceFrom |
AlphaNumeric (50) |
Code of substance (must correspond to values in id column of Substances table) |
idSubstanceFrom, SubstanceIdFrom, SubstanceCodeFrom, SubstanceFrom |
Yes |
ExposureRouteFrom |
ExposureRoute | The exposure route (only applicable if target level is external). If not specified, Dietary is assumed. |
ExposureRoute |
No |
Biological matrix from |
BiologicalMatrix | If applicable, the source matrix of the human body (e.g., blood, urine) to convert from. When specified, the measurements are considered at the level of internal doses. |
MatrixSource, SourceMatrix |
No |
DoseUnitFrom |
DoseUnit | The unit of the substance dose to convert from. |
UnitSource, SourceUnit |
Yes |
ExpressionTypeFrom |
ExpressionType | The expression type or adjustment method of the dose unit (from). This field specifies how the dose unit (source) is adjusted, e.g. for blood lipids for fat soluble biomarkers (‘mg/g lipids’) or the dilution level of the urine (‘mg/g creatinine’). |
ExpressionTypeFrom, AdjustmentMethodFrom |
No |
idSubstanceTo |
AlphaNumeric (50) |
Code of substance (must correspond to values in id column of Substances table) |
idSubstanceTo, SubstanceIdTo, SubstanceCodeTo, SubstanceTo |
Yes |
ExposureRouteTo |
ExposureRoute | The exposure route (only applicable if target level is external) to convert to. If not specified, Dietary is assumed. |
ExposureRoute |
No |
Biological matrix to |
BiologicalMatrix | If applicable, the matrix of the human body (e.g., blood, urine) to convert to. When specified, the measurements are considered at the level of internal doses. |
MatrixTarget, TargetMatrix |
No |
DoseUnitTo |
DoseUnit | The unit of the substance dose to convert to. |
UnitTarget, TargetUnit |
Yes |
ExpressionTypeTo |
ExpressionType | The expression type or adjustment method of the dose unit (to). This field specifies how the dose unit (target) is adjusted, e.g. for blood lipids for fat soluble biomarkers (‘mg/g lipids’) or the dilution level of the urine (‘mg/g creatinine’). |
ExpressionTypeTo, AdjustmentMethodTo |
No |
ConversionFactor |
Numeric |
Conversion factor value |
ConversionFactor, Factor |
Yes |
UncertaintyDistributionType |
KineticConversionFactorDistributionType | Distribution type (Uniform, LogNormal, Beta or InverseUniform). If not specified, the conversion is assumed to be a constant factor. |
UncertaintyDistributionType, UncertaintyDistribution, DistributionType, Distribution |
No |
UncertaintyUpper |
Numeric |
The upper value of the distribution. If the distribution is uniform, then it is the upper bound of the uniform distribution. If the distribution is log-normal, then the upper value is assumed to correspond with the p95 percentile of the distribution. When a distribution is assumed, this value should be greater than the conversion factor. |
UncertaintyUpper, Upper |
No |
Kinetic conversion factor subgroups
Kinetic conversion factor subgroups.
Accepted table names: KineticConversionFactorSGs, KCFactorSubGroups.
| Name | Type | Description | Aliases | Required |
|---|---|---|---|---|
idKineticConversionFactor |
AlphaNumeric (50) |
Id of the kinetic conversion factor |
idKineticConversionFactor, idConversionFactor, idKCFactor |
Yes |
ConversionFactor |
Numeric |
Conversion factor value |
ConversionFactor, Factor |
Yes |
AgeLower |
Numeric (50) |
Specifies the lower bound of the age interval (in years) of the kinetic conversion factor subgroup. Individuals belong to a subgroup when the age of the individual is equal or greater than the specified lower bound and smaller than the specified lower age of the next subgroup. |
AgeLower, LowerAge |
No |
Gender |
GenderType | The gender of the kinetic conversion factor subgroup. |
Gender, Sex |
No |
UncertaintyUpper |
Numeric |
The upper value of the distribution. If the distribution is uniform, then it is the upper bound of the uniform distribution. If the distribution is log-normal, then the upper value is assumed to correspond with the p95 percentile of the distribution. When a distribution is assumed, this value should be greater than the conversion factor. |
UncertaintyUpper, Upper |
