In the presented research parameters of the extraction procedure were optimised for simultaneous determination of butyl-, phenyl- and octyltin compounds in sewage sludge. Extracted OTCs were derivatised with sodium tetraethylborate and determined by GC-MS. Quantitative extraction of butyl-, phenyl- and octyltin compounds was obtained by the use of glacial acetic acid as extractant and mechanical stirring for 16 h or sonication for 30 min. The limits of detection and quantification for OTCs investigated in sewage sludge were in the ng Sn g-1 range.
