Risks settings

Calculation settings

Table 198 Calculation settings for module Risks.
Name Description

Multiple substances analysis

Specifies whether the assessment involves multiple substances.

Express results in terms of reference substance equivalents (cumulative)

Specifies whether the assessment involves multiple substances and results should be cumulated over all substances.

Health effect type

Specifies whether the health effect is a risk (negative) or benefit (positive).

Risk metric type

Report risks in terms of hazard index (HI = 1/MOE) or margin of exposure.

Show equivalent animal dose output

Specifies whether equivalent animal doses should be reported in the output.

Threshold safety plot

Threshold for interpretation in the margin of exposure or hazard index plot, e.g. MOE = HI = 1 or MOE = 100.

Use inverse distribution to calculate percentile

Calculate percentile via the complementary percentage of the inverse distribution (default: no). Description: E.g., P0.1 of MOE distribution is calculated via P99.9 of 1/MOE distribution. Note: This option is provided because percentile calculation in small data sets is asymmetric in both tails.

Target level

Select to express hazard characterisations at external or internal exposure level.

Risk type

The type of exposure considered in the assessment; acute (short term) or chronic (long-term).

Output settings

Table 199 Output settings for module Risks.
Name Description

Number of plot labels

Maximum number of labels to plot in hazard vs exposure plot.

Number of substances in hazard vs. exposure plot

Maximum number of substances to plot in hazard vs exposure plot.

Left margin safety plot

Left margin of the plot for margins of exposure or hazard indices.

Right margin safety plot

Right margin of the plot for margins of exposure of hazard indices.

Inclusion percentage variability interval

The central percentage of the variability distribution to include in intervals for exposure, hazard and MOE (e.g. 90 means p5-p95).

Include drill-down on 9 individuals around specified percentile.

Specifies whether drilldown on 9 individuals is to be included in the output.

Summarize simulated data

Specifies whether a summary of the simulated consumptions and concentrations should be included in the output.

Store simulated individual day exposures

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

Give specific percentiles of exposure distribution (%), e.g. 50 90 95 97.5 99 (space separated).

Percentage for drilldown

Gives detailed output for nine individuals near this percentile of the exposure distribution.

Percentage for upper tail

Gives detailed output for this upper percentage of the exposure distribution.

Show % of population below level(s)

Exposure levels can be generated automatically or by explicit specification (Manual).

Exposure levels

Specify exposure levels for which to give the percentage of exposure below these levels, e.g. 1 10 50 100 200 500. Specify below whether these levels are absolute or relative to ARfD/ADI.

Exposure levels are

Specify whether exposure levels are absolute or percentages of ARfD/ADI.

Number of levels of covariable to predict exposure

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

Specify specific prediction levels in addition to the automatically generated prediction levels (space separated).

Lower percentage for variability (%)

The default value of 25% may be overruled.

Upper percentage for variability (%)

The default value of 75% may be overruled.

Report consumptions and exposures per individual instead of per kg body weight

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.
