What is EURL POPs?

This proficiency test (PT) on the determination of perfluoroalkyl substances (PFAS) in liquid whole egg (mandatory) and honey (voluntary) was organised by the EURL for halogenated Persistent Organic Pollutants (POPs) in Feed and Food to be performed between August and October 2021 for liquid whole egg. The objective was to assess analytical performance of laboratories and the interlaboratory comparability of results from analyses of short and long chain perfluoroalkyl carboxylic acids and short and long chain perfluoroalkyl sulfonic acids in fortified food samples. These reports summarize the assigned values and participants' results, as well as the z-scores for PFCAs, PFSAs and PFASs sum parameters in two samples of liquid whole egg and one honey sample.

This interlaboratory study (ILS) on the determination of brominated contaminants (BCons) and polychlorinated naphthalenes (PCNs) in cod liver oil was organized by the European Union Reference Laboratory (EURL) for halogenated persistent organic pollutants (POPs) in Feed and Food to be performed between July and September 2021. The objective was to assess interlaboratory comparability of results from BCons and PCNs in a fortified food sample. This report summarizes the assigned values and participants' results, as well as the z-scores for PBDES, HBCDDs, TBBPA, eBFRs, and PCNs in a sample of cod liver oil.

This interlaboratory study (ILS) on the determination of several brominated contaminants (BCons), polychlorinated naphthalenes (PCNs) and chlorinated paraffins (CPs) in fish oil is organized by the EURL for halogenated POPs in Feed and Food to be performed between May and September 2022 (first deadline) or March 2023 (second deadline). The objective is to characterize a quality control material for method development purpose and quality control during routine analysis. Therefore up to five sets of results for all analyte groups can be reported until each deadline using the same or different methods. In addition, the focus is on the assessment of intra- and interlaboratory comparability of results from PBDEs, HBCDDs, TBBPA, eBFRs, PBDD/Fs, PXDD/Fs, PCNs and CPs in two fish oil samples.
