AI Article Synopsis
- The study investigated the presence of polycyclic aromatic hydrocarbons (PAHs) in Spheniscus magellanicus (Magellanic penguins) along the coast of São Paulo, Brazil, by analyzing their biliary metabolites.
- 79 penguins, either found dead or admitted to rehabilitation, were tested for metabolites of three specific PAHs: naphthalene, phenanthrene, and benzo[a]pyrene, using advanced liquid chromatography techniques.
- Results showed a range of total metabolite concentrations, primarily consisting of naphthalene metabolites, with benzo[a]pyrene detected in only two samples, marking a pioneering effort in assessing PAH bioavailability in this species.
Article Abstract
Bioavailability of polycyclic aromatic hydrocarbons on São Paulo state coast (southeastern Brazil) was evaluated through the analysis of biliary metabolites in Spheniscus magellanicus (n = 79). The animals analyzed in present study were either found dead during beach monitoring procedures or died at rehabilitation centers. Analyses of naphthalene (NAP), phenanthrene (PHE) and benzo[a]pyrene (BaP) metabolites were performed using a high-performance liquid chromatograph equipped with fluorescence detectors. Total metabolite (TM) concentrations ranged from below the method quantification limit to 270 μg g of bile. TM concentrations were mainly composed of NAP metabolites, followed by PHE metabolites. BaP metabolites were detected in only two samples. This is the first study using PAHs metabolites in S. magellanicus to assess the bioavailability of these compounds in coastal regions.
