Analytical quality control of tributyltin in the environmentFunded under: FP2-BCR 4
Considerable concern has been expressed over the toxic effects of tributyltin (TBT) on marine organisms. In order to improve the quality of analysis, the Community Bureau of Reference (BCR) organised a programme starting in 1988 with intercomparison exercises of organotins in solutions (tributyltin, tributyltin together with mono- and dibutyltin, tributyltin mixed with triphenyltin). The good quality of the results obtained led to a next step in 1989 in which analysis of a TBT-spiked sediment was performed. This contribution presents the results obtained in the two studies. Different analytical techniques were used, generally based on extraction and derivatisation steps and chromatography coupled to different detection methods (e.g. AAS, FID, PFD, MS ...). The aim of the whole project is to remove the bias caused by systematic errors at different steps of the analyses as obtained in different laboratories; its final goal is to produce TBT certified reference materials (e.g. industrially polluted and coastal sediment, and mussel tissue). A first certification (TBT in industrially polluted sediment) is foreseen for 1990-1991.
