The aim of this study is to assess-for the first time-the concentration of the 16 polycyclic aromatic hydrocarbons (PAHs) in the muscle tissues of four fish species (Micropogonias furnieri, Cynoscion guatucupa, Ramnogaster arcuata, and Mustelus schmitti) from Bahía Blanca estuary, Argentina and to evaluate their sources, distribution, and the human health risks implicated. Considering the four species under study, mean total PAH concentrations showed the following decreasing accumulation trend: M. schmitti, R. arcuata, C. guatucupa, and M. furnieri. Low molecular weight PAHs, such as naphthalene and phenanthrene, were generally predominant, displaying properties of PAH mixtures generated from petrogenic pollution. Of the four fish species analyzed, M. furnieri was the only one that did not raise any human consumption warning. In the case of the other species, exceeding values were found above the safety human consumption guidelines. Nevertheless, the screening criteria for carcinogenic PAHs proposed by the USEPA indicated a good quality status for these fish species.
本研究旨在首次评估阿根廷布兰卡港河口 4 种鱼类（小沙丁鱼、南美拟犬牙石首鱼、弓头石首鱼和尖吻狼牙䱛）肌肉组织中 16 种多环芳烃（PAHs）的浓度，并评估其来源、分布和涉及的人类健康风险。在所研究的 4 种鱼类中，总多环芳烃浓度的积累呈以下降低趋势：M. schmitti、R. arcuata、C. guatucupa 和 M. furnieri。低分子量的多环芳烃，如萘和菲，通常占主导地位，表现出源自石油污染的多环芳烃混合物的特性。在所分析的 4 种鱼类中，M. furnieri 是唯一一种没有引起人类食用警告的鱼类。对于其他鱼类，发现超过了安全人类食用指南的限值。然而，美国环保署提出的致癌多环芳烃筛选标准表明，这些鱼类的状况良好。
