Validation of analytical method for determination of tributyltin (TBT) in soils and bottom sediments

Abstract

Tributyltin (TBT) belongs to the group of persistent pollutants harming the marine environment. It is a danger to many aquatic organisms, especially those inhabiting seabed sediments. TBT was used mainly in production of antifouling paints applied on ship’s hulls. Currently, it is prohibited to use most products containing TBT [6; 8; 16]. The objective of this study was to confirm applicability of the method for determining the levels of tributyltin compounds in soils and bottom sediments which remains in accordance with the HELCOM recommendations [11]. In Poland, there is no sufficient data on the levels of TBT concentrations in the Baltic Sea, which is why it is so important to monitor these compounds in the seabed sediments, where they tend to accumulate.
