Abstract
High resolution photoplate mass spectrometry has been used to examine crude goat urine extracts to determine the fate of organochlorine xenobiotics in these animals. Using a direct introduction temperature controlled probe the crude urine extracts were analyzed and the presence of oxygenated metabolites of 4-chlorobiphenyl and 4,4′-dichlorobiphenyl were confirmed in goats; analyses of urine extracts from goats injected with the commercial Aroclor mixtures 1254 and 5460 confirmed the formation of oxygenated penta-, tetra- and monochlorobiphenyl metabolites and an oxygenated dichloroterphenyl metabolite, respectively. This technique was particularly useful in the analysis of complex mixtures of metabolites.
