Abstract

Since 1988 the European Commission (through the BCR activity) has been active in the area of speciation analysis through the organisation of interlaboratory studies and the production of reference materials. The efforts enabled us to evaluate the international state of the art for the determination of various organometal species. One of the programmes concerned the quality control of organotin analyses in environmental matrices. This paper gives an outline of this programme and describes the latest material produced, a freshwater sediment (BCR 646) certified for tributyltin, dibutyltin, monobutyltin, triphenyltin, diphenyltin and monophenyltin. Details of the production, homogeneity and stability of the reference material are given. The results of the certification are evaluated from a technical and a statistical point of view. © Elsevier Science B.V.
