Preliminary results for the improvement of TBT determination in the environmentFunded under: FP2-BCR 4
A considerable concern has been expressed in the past few years with regard to the toxic effects of tributyltin (TBT) on marine organisms. Numerous monitoring surveys were performed to control the levels of contamination in the environment in the past five years, mostly in enclosed bays where shell-fisheries were shown to be affected. However, it was not possible at this stage to control the quality and the validity of the determinations. In order to improve this situation, the Community Bureau of Reference organised intercomparison exercises on organotin determination in solution. Four solutions were used for this purpose: containing TBT, TBT together with mono- and dibutyltin, TBT together with triphenyltin, and a mixture of all the mentioned species. The results of this preliminary intercomparison exercise are presented. The next stage involves an intercomparison exercise on TBT determination in a TBT-spiked sediment. The final stage will be the certification of TBT in various materials, e.g. industrial harbour and coastal sediments, and mussel tissues.
