CF: conversion factor; PF: processing factor.
n.c.: not calculated; products were not analysed for al compounds included in the RD‐RA (conjugated M21 was not determined).
CFp: Conversion factor for risk assessment in processed commodity (= Residue level in processed commodity expressed according to RD‐RA/Residue level in processed commodity expressed according to RD‐Mo).
Studies with residues in the RAC at or close to the LOQ were disregarded (unless concentration may occur).
Conversion factor for risk assessment in the processed commodity; median of the individual conversion factors for each processing residues trial.
A tentative PF is derived based on a limited data set (EFSA, 2021).
CF from trials with radiolabelled 1,4‐dimehtylnephthaline (EFSA, 2021) can be used for similar processing procedures.
From metabolism trials M21 conjugates are not expected in potato peels (EFSA, 2017). CF calculated based on residues of parent and free M21.
Residue data on conjugated M21 are not available. The CF from primary crops can be considered instead for risk assessment. However, if more information would be required by risk managers processing trials with radiolabelled 1,4‐dimehtylnaphthaline should be performed.
