Includes bibliographical references. "Butyltin chlorides spiked onto glass fibre filters and XAD-2 resin were extracted in toluene using two different chelating agents, either tropolone with acetic acid or sodium diethyldithiocarbomate (NaDDC), and derivatized with pentylmagnesium bromide. Derivatized butyltin species were determined by gas chromatography with plasma atomic emission detection (GC-AED). Higher extraction recoveries were obtained using NaDDC as the chelating agent. Glass fibre filters and XAD-2 resin were both determined to be suitable air sampling media for the analysis of butyltin compounds"--Abstract.
