Wild Mediterranean mussels (Mytilus galloprovincialis) were collected from 10 coastal sites of Port Phillip Bay, Australia, and 16 types of Polycyclic aromatic hydrocarbons (PAHs) in their bodies were measured. Also, mussels from 4 of the 10 sites were sampled and the activities of Metallothioneins (MTs), superoxide dismutase (SOD), glutathione S-transferase (GST), and Ethoxyresorufin -o- deethylase (EROD) in the gills were tested. The results demonstrated spatial variation of different PAHs in mussels, which differed from trace metal accumulations to mussels reported in previous studies. Besides, the results of SOD, GST, and EROD showed highly similar features among mussels from all the sites while the results of MTs appeared to be different. The estimation of possible excessive cancer risks caused by wild mussel consumption using the results in this study demonstrated that the PAHs in wild mussels in Port Phillip Bay is a moderate concern for consumers.

野生地中海贻贝（Mytilus galloprovincialis）收集自澳大利亚菲利普港湾的10个沿海地点，并测量了其体内的16种类型的多环芳烃（PAH）。此外，还从10个地点中的4个地点取样了贻贝，并测试了ill中的金属硫蛋白（MTs），超氧化物歧化酶（SOD），谷胱甘肽S-转移酶（GST）和乙氧基视黄素-o-脱乙基酶（EROD）的活性。结果表明贻贝中不同PAH的空间变化，不同于先前研究中报道的痕量金属积累和贻贝。此外，在所有地点的贻贝中，SOD，GST和EROD的结果显示出高度相似的特征，而MT的结果似乎有所不同。
