A new sensitive and selective gas chromatography tandem mass spectrometry (GC-MS/MS) method was developed for the analysis of 26 polycyclic aromatic hydrocarbons (PAHs), including 16 Environmental Protection Agency (EPA) and 15 + 1 European Union (EU) PAHs, in mussel samples from aquaculture farms in Thermaikos and Strymonian Gulf, Central Macedonia Region, in three sampling periods. Concentrations were found at moderate to low values at all sampling sites, without exceeding maximum levels set by EU. Low molecular weight PAHs were predominant in all samples. Seasonal variation of the concentrations was observed; values were slightly higher in the winter period. Use of diagnostic ratios for potential sources of PAHs showed both petrogenic and pyrolitic origin. In comparison to other related studies of mussels from the Mediterranean Sea, Greek mussels cultivated in the studied gulfs are low in contaminants due to minimal environmental pollution effects. Low concentrations of PAHs are in compliance with the low values of other POPs which were found in the mussels.
开发了一种新的灵敏且选择性的气相色谱串联质谱法（GC-MS/MS），用于分析来自中马其顿地区塞尔迈湾和斯特里蒙湾水产养殖场贻贝样本中的26种多环芳烃（PAHs），包括16种美国环境保护局（EPA）规定的以及15 + 1种欧盟（EU）规定的PAHs，采样期为三个阶段。在所有采样点测得的浓度处于中低水平，未超过欧盟设定的最高限值。所有样本中低分子量PAHs占主导。观察到浓度存在季节性变化；冬季的值略高。利用PAHs潜在来源的诊断比率表明其具有成岩和热解成因。与地中海贻贝的其他相关研究相比，在所研究海湾养殖的希腊贻贝因环境污染影响极小，污染物含量较低。PAHs的低浓度与贻贝中发现的其他持久性有机污染物的低含量相符。
