Exposures settings
Calculation settings
| Name | Type | Description |
|---|---|---|
Risk type
|
ExposureType | The type of exposure considered in the assessment; acute (short term) or chronic (long-term). |
Multiple substances analysis
|
Boolean |
Specifies whether the assessment involves multiple substances. |
Compute cumulative exposures
|
Boolean |
Specifies whether the assessment involves multiple substances and results should be cumulated over all substances. |
Include dietary and non-dietary routes of exposure
|
Boolean |
Specifies whether the assessment involves both dietary and non-dietary (oral, inhalatory or dermal) routes of exposure. |
Target level
|
TargetLevelType | Select to express hazard characterisations at external or internal exposure level. For an aggregate assessment, that is dietary and nondietary exposure data are combined, the target dose level is always internal. When only dietary exposures are available, the target dose level is optional, i.c. external or internal. |
Match non-dietary to dietary survey individuals
|
Boolean |
Specifies whether the individuals of one or more non-dietary surveys should be matched to individuals in the dietary survey according to the individual codes (idIndividual). If unchecked, nondietary exposures are randomly allocated to dietary survey individuals. |
Match individuals of multiple non-dietary surveys
|
Boolean |
If checked, exposures from identical individuals in non-dietary surveys are aggregated to obtain the overall nondietary exposures. If unchecked, exposures from random individuals in all non-dietary surveys are aggregated. |
Model-then-add
|
Boolean |
Specifies whether to create separate exposure models for specific groups of modelled foods (model-then-add). |
Kinetic model
|
AlphaNumeric |
Code Kinetic Model. |
Specify the type of kinetic model
|
InternalModelType | Specify the type of model to convert external exposure to the internal level. |
Substance weighting for MCR
|
ExposureApproachType | Risk based: exposures in equivalents of the reference substance; standardised: standardised exposures per substance have variance 1; or unweighted exposures: RPFs are equal to 1. |
Perform MCR analysis
|
Boolean |
Perform a Maximum Cumulative Ratio (MCR) analysis to determine co-exposure between substances. |
Display ratio total exposure/ maximum (in MCR plot)
|
Numeric |
For MCR plot: specify ratio total exposure/ maximum for individual(day) exposures . |
Show tail percentiles (MCR plot) for:
|
AlphaNumeric |
Give specific percentiles of exposure distribution (%), e.g. 97.5 99 (space separated). |
Set minimum percentage contribution per substance to the tail exposure (MCR plot)
|
Numeric |
Set minimum percentage contribution per substance to the tail exposure. |
Output settings
| Name | Type | Description |
|---|---|---|
Include drill-down on 9 individuals around specified percentile.
|
Boolean |
Specifies whether drilldown on 9 individuals is to be included in the output. |
Summarize simulated data
|
Boolean |
Specifies whether a summary of the simulated consumptions and concentrations should be included in the output. |
Store simulated individual day exposures
|
Boolean |
Store the simulated individual day exposures. If unchecked, no additional output will be generated. If checked, the output will contain an additional section with the simulated individual day exposures. |
Show percentiles for
|
AlphaNumeric |
Give specific percentiles of exposure distribution (%), e.g. 50 90 95 97.5 99 (space separated). |
Percentage for drilldown
|
Numeric |
Gives detailed output for nine individuals near this percentile of the exposure distribution. |
Percentage for upper tail
|
Numeric |
Gives detailed output for this upper percentage of the exposure distribution. |
Show % of population below level(s)
|
ExposureMethod | This setting is used for reporting the percentages of individuals (chronic) or individual days (acute) exceeding certain exposure levels. These exposure levels can be generated automatically based on the observed exposures (Automatic, default) or specified explicitly (Manual). |
Exposure levels
|
AlphaNumeric |
Specify exposure levels for which to give the percentage of exposure below these levels, e.g. 1 10 50 100 200 500. |
Number of levels of covariable to predict exposure
|
Numeric |
Specify the number of levels, e.g. 20. The range of the covariable is divided by the number of levels: range = (max - min)/levels. For these covariable levels exposures are predicted. |
Predict exposure at extra covariable levels
|
Numeric |
Specify specific prediction levels in addition to the automatically generated prediction levels (space separated). |
Lower percentage for variability (%)
|
Numeric |
The default value of 25% may be overruled. |
Upper percentage for variability (%)
|
Numeric |
The default value of 75% may be overruled. |
Report consumptions and exposures per individual instead of per kg body weight
|
Boolean |
Specifies whether body weights should be ignored and consumptions and exposures should be expressed per individual. Otherwise, the consumptions and exposures are per kg body weight. |
Uncertainty settings
| Name | Type | Description |
|---|---|---|
Resample kinetic model parameter values
|
Boolean |
Specifies whether kinetic model parameter values are resampled. |
