摘要：
Perfluorinated compounds are widespread pollutants of toxicological importance that have been detected in environmental matrices. However. little is known on their distribution in South America. In this study, distribution of perfluorooctanesulfonate (PFOS), perfluorooctanoic acid (PFOA). perfluorohexanesulfonate (PFHxS), and perfluorooctanesulfonamide (PFOSA) was determined in the bile of mullet, Mulgil incilis, and in tissues of pelicans (Pelecanus occidentalis) collected from North Colombia. Analysis was performed by HPLC mass spectrometry after ion-pair extraction. PFOS was found in all bile samples and PFOA and PFHxS were detected at lower frequency. Average concentrations of PFOS, PFOA, and PFHxS in bile of fish from Cartagena Bay, an industrialized site, and Totumo marsh, a reference site, were 3673, 370, 489 and 713, 47.4, 1.27 ng/mL. respectively. PFOS concentrations in pelican organs decreased in the order of spleen > liver > lung > kidney > brain > heart > muscle. These results suggest, for the first time, that perfluorinated compounds are also found in wildlife front Latin American countries. (c) 2005 Elsevier Ltd. All rights reserved.
