- Commodity risk assesment
- EFSA pest catogorisation - what are the categories?
- Quarantine pest - what are the criteria for this category?
- Statuary action - which actions are usually taken?
- Interception databases
- Margin of exposure (MOE)
- Terms of Reference
- Uncertainty analysis - want to know more about it in the risk assessment practice

Phytotoxicity
Incursion
“Adult weevils live for approximately four months and will feed on leaf edges, leaving irregular semi-circular notches which causes little economic damage” - How does it cause economic damage?

How does the writer judge the level of the confidence of the assessment?

How is the risk level assessed, how to refine the judgment on whether an assessment result is "unlikely" or "very unlikely"? is there a quantitative standard for it?

ERA / RLA

ERA:

PEC / PNEC ratio
- Why is the metabolism rate after administration not considered when calculating the Predicted Environmental Concentration (PEC)?
Environmental Fate

RLA:

How does uncertainty in previous data (like variation in concentration) affect the conclusions in the risk level?

Margins of Exposure?

HRA

ekolusa — 2025-09-03 12:00:26 UTC

Assumptions about

1) Toddlers - long term exposure

2) Genetic susceptibility

RLA

ekolusa — 2025-09-03 12:46:42 UTC

Assumptions:

1) regarding reliability in data, some data more noisy or with more variability

2) regarding validity of data, does it measure what we want to know about
