Kurzfassung:
A method is described for the quantitative analysis of silvex and its propylene glycol butyl ether ester in fish tissue. A methanolic extraction and gas chromatographic detection yielded recoveries from fortified fish tissue of 80 to 96% at levels of 0.005 to 1 ppm for the ester and 84 to 98% at 0.002 to 1 ppm for the acid. In an additional recovery study, the extraction procedure was monitored with the PGBE ester labeled at the carboxylic carbon (14C). Live fish were exposed to an aqueous environment containing the labeled PGBE ester and were extracted by the procedure. It was found that 95% of the PGBE ester and its degradation products can be extracted from the tissue with methanol.
