Popis:	Tributyltin (TBT) concentrations have been measured in UK waters, shellfish and sediments during the period 1986–1992. The methodology was based on conversion of alkyltin compounds to hydrides following extraction, and then measurement by gas chromatography with flame photometric detection. The collection of a large set of data to assess changes in environmental concentrations of organotins required use of good analytical quality control procedures at a time when no reference materials were available. An analytical quality control (AQC) system based on in-house quality control materials was devised and the performance of the method independently assessed by periodic participation in intercalibration exercises with other expert laboratories.
