What is EURL POPs?

This proficiency test (PT) on the determination of PCDD/Fs, PCBs, PBDEs, HBCDDs and PFASs in milk powder was organized by the EURL for halogenated POPs in Feed and Food to be performed between February and April 2023. The objective was to assess analytical performance of laboratories and interlaboratory comparability of results from analyses of PCDD/Fs, PCBs, PBDEs, HBCDDs and PFASs in one sample of milk powder. These reports summarize the assigned values and participants' results, as well as the z-scores for PCDD/Fs, PCBs, PBDEs, HBCDDs and PFASs in one sample of milk powder.

This proficiency test (PT) on the determination of PCDD/Fs, PCBs, PBDEs, HBCDDs and PFASs in fish meal was organized by European Union Reference Laboratory (EURL) for halogenated persistent organic pollutants (POPs) in Feed and Food to be performed between September and November 2022. The objective was to assess analytical performance of laboratories and interlaboratory comparability of results from analyses of PCDD/Fs, PCBs, PBDEs, HBCDDs and PFASs in one sample of fish meal. These reports summarize the assigned values and participants' results, as well as the z-scores for PCDD/Fs, PCBs, PBDEs, HBCDDs and PFASs in one sample of fish meal.

This document summarizes background information and synthesises of supporting information on the prioritisation of specific PCN congeners in food. It is intended to support laboratories in method development and also to support future assessments with relevant as well as harmonised data. The guidance in this document is intended for laboratories involved in the official control of contaminants in food as part of the EURL’s official mandate and scope of work.
