MRL: maximum residue level; GAP: Good Agricultural Practice; Mo: monitoring; RA: risk assessment. Individual conversion factors (CFs) between residues according to the RD for monitoring and the RD for risk assessment were not derived.

*: Indicates that the MRL is proposed at the limit of quantification.

(a) NEU: Outdoor trials conducted in northern Europe, SEU: Outdoor trials conducted in southern Europe.

(b) Highest residue. The highest residue for risk assessment refers to the whole commodity and not to the edible portion.

(c) Supervised trials median residue. The median residue for risk assessment refers to the whole commodity and not to the edible portion.

(d) Conversion factor between monitoring and risk assessment considering the median value of available trials.

(e) Higher residue value at a longer PHI of 14 days.

(f) Higher residue value in control sample.

(g) Higher value in control sample and at a longer PHI of 14 days.
