Workshops for NRLs and the EU Commission are organized twice a year. At these workshops especially the results of interlaboratory studies are presented and important reagulatory and analytical issues discussed.

Amongst other topics, criteria for extraction of mineral feed and analytical requirements for the determination of non dioxin-like PCBs, bioanalytical screening methods and new confirmatory methods were developed.
