Retrospective dietary CRA (EC 2018) - Acute / Tier I
Retrospective dietary CRA (EC 2018) - Chronic / Tier I
Retrospective dietary CRA (EC 2018) - Acute / Tier II
Retrospective dietary CRA (EC 2018) - Chronic / Tier II
Retrospective dietary CRA (EFSA 2012) - Optimistic
Use the optimistic model settings according to the EFSA Guidance 2012. Concentration values are sampled using a sample-based empirical distribution. Available processing factors are applied. No unit variability model should be applied.
Retrospective dietary CRA (EFSA 2012) - Acute / Pessimistic
Acute probabilistic exposure assessment using the pessimistic model settings according to the EFSA Guidance 2012. Only processing factors > 1 are applied. For unit variability, the Beta distribution is applied.
Retrospective dietary CRA (EFSA 2012) - Chronic / Pessimistic
Chronic probabilistic exposure assessment using the pessimistic model settings according to the EFSA Guidance 2012. Only processing factors > 1 are applied.
