Abstract

In order to check the possible occurrence of degradation of tributyltin and triphenyltin in mussel samples during their storage, a 1-year stability study was carried out. Analyses by gas chromatography with flame photometric detection and gas chromatography-mass spectrometry were performed on freeze-dried mussel samples stored under different conditions of temperature and light. The results showed that very good stability of butyl- and phenyltins can be achieved when samples are stored at -20°C in the dark. In contrast, samples stored at room temperature showed significant variations in organotin speciation, particularly in the presence of light. © 1994.
