In the year 2000, organotin pollution was investigated in the Bay of Piran, Slovenia, at the northern extremity of the Adriatic Sea. Gas chromatography-mass spectrometry with single ion monitoring GC/MS-SIM was applied for speciation analysis of pentylated organotin compounds in water and mussels. Sampling of marine waters was performed in summer and autumn at 8 locations. Mussels Mytilus galloprovincialis were collected only in summer at 3 locations. The highest concentrations of tributyltin (TBT) in marine water ranged from 500 to 630 ng L⁻¹ (as Sn) in summer and from 180 to 230 ng L⁻¹ (as Sn) in autumn. TBT concentration in mussels varied from 500 to 3500 ng g⁻¹ dry weight (d.w.) (as Sn). The study indicated remarkable butyltin pollution of the Slovenian coastline. Accuracy of the analytical procedure was verified by BCR CRM 477.
