Contribution of the Community Bureau of Reference (CBR) of the Commission of European Communities (CEC) to quality improvement and certification of reference materials for PCDD- and PCDF-analysis
In the framework of the BCR-programme, collaborative systematic tests were carried out to investigate sources of error in the determination of dioxins and chlorinated dibenzofuranes. This paper presents the various experiments made and the consequent improvement of the performance of the methods used in the participating laboratories. A good agreement between results on a fly ash extract has been obtained by using different methods. These results are given and discussed. Certification of a fly ash now seems feasible.
