Resumen:
Bivalves, especially mussels, have been pointedas putative species to monitor polycyclic aromatic hydrocarbons(PAHs) in marine environment. After severalenvironmental PAHs baseline reports, the present studywas conducted to assess for the first time the levels ofPAHs in native mussels (Brachidontes rodriguezii) collectedfrom a critical industrialized estuary of Argentina.Under this objective, after an 18-month sampling period,34 pools of mussels were assessed for 17 PAHs, includingthe 16 compounds prioritized by United States EnvironmentalProtection Agency. By means of gas chromatography?mass spectrometry analysis, results showed totalPAHs concentrations in mussel?s tissue ranged from underlaboratory detection limits to 482.4 ng/g dry weight.Mussel body burdens were dominated by lower molecularweight PAHs, such as phenanthrene, naphthalene, andpyrene, whereas the overall PAHs profile suggested thepredominance of petrogenic sources. Finally, the potentialecotoxicological impact was evaluated by applyingEnvironmental Assessment Criteria and benzo[a]pyrenetoxic equivalent factors.
