“…Bereits in einer friiheren Veroffentlichung [8] The contamination of surface water with biocidal organotin compounds must be considered as particularly dangerous. Even slightest traces of tributyltin compounds proved to be very toxic to lowcr aquatic organisms, which may produce a displacement of the biological equilibrium A possibility of the determination of such compounds by means of anodic stripping polarography has already been described i n a previous paper.…”

Eine besondere Gefahr ist in der Kontamination des Oberflachenwassers durch biozide Organozinn-Verbindungen zu sehen. Schon geringste Spuren von Tributylzinn [5][6][7]. Fast ausschlieBlich handelt es sich uni indirekte Verfahren, wobei der eigentliche Wirkstoff sowie Abbau-bzw. Umwandlungsprodukte nicht erfaI3t werden. Die Selektivitat des Verfahrcns ist dadurch stark eingeschrankt und entspricht nicht mehr den hcutigen lebensmitteltosikologisclien Anforderungen der modernen Riickstandsanalyse und -beurteilung. Durch Anwendung der Inversvoltammetrie in Kombination mit dcr Dunnscliichtchromatographie konnen diese Nachteile ausgeschaltct werdcri. Gegeniiber den bekannten Methoden ist das Verfahrcn selektiv, da auch die ntalkylierten Produkte erfaBt werden und die Nachweisgrenze urn etwa eine Zehnerpotenz erniedrigt wird.

“…The toxicity of organotin compounds for mammalian has been known to give the following symptoms;l) loss of appetite, thirst and diarrhoea. In general, residue determination of organotin compounds has been carried out by polarography2) or anodic stripping method 3 ) on the basis of tin, but the sample preparation is much complicated. In this paper, we report a convenient method using the direct-insertion selected ion monitoring method which is not necessary to ash.…”

“…Conventional TLC has been used to separate butyltin compounds, subsequently detected using chemical oxidation and colorimetry of the pyrocatechol-complex [ 3 ]. TLC has also been used to speciate organotin compounds that were detected by anodic stripping voltammetry [ 4 ]. A study of the mammalian metabolism of organotins used normal and two-dimensional TLC, followed by photolysis and treatment with visualizing reagents (8-hydroxy-5-sulfonic acid, pyrocatechol violet, or dithizone) to identify the chromatographic components [ 5 ].…”
