Atmospheric polycyclic aromatic hydrocarbons (PAH) were determined in two places in a suburban area of Athens greater area (AGA) during June and November 2003. Fourteen PAHs were quantified in the collected samples. The total concentration in the gas phase ranged between 6.89 and 124ngm(-3), while in the particulate phase between 0.44 and 13.2ngm(-3). Maximum concentrations of the total PAHs (gas and particulate phase) were observed during the cold period with an average of 40.7ngm(-3). PAHs were correlated with NO, NO(2) and O(3), wind speed, wind direction and temperature. Positive correlation was observed between PAHs and NO, NO(2), while negative correlation was detected between PAHs and O(3). The most abundant members were phenanthrene, anthracene, fluorene, fluoranthene and pyrene. Potential sources of PAHs in aerosols were investigated using molecular diagnostic ratios, which reflect sources such as diesel and gasoline engines, although other sources such as coal combustion and liquefied petroleum gas also contributed.
2003年6月和11月，在雅典大都市区（AGA）郊区的两个地点测定了大气中的多环芳烃（PAH）。在所采集的样本中对14种多环芳烃进行了定量分析。气相中的总浓度在6.89至124纳克/立方米之间，而颗粒相中的总浓度在0.44至13.2纳克/立方米之间。在寒冷时期观测到总多环芳烃（气相和颗粒相）的最高浓度，平均为40.7纳克/立方米。多环芳烃与一氧化氮、二氧化氮和臭氧、风速、风向及温度相关。多环芳烃与一氧化氮、二氧化氮之间呈正相关，而多环芳烃与臭氧之间呈负相关。含量最丰富的成分是菲、蒽、芴、荧蒽和芘。利用分子诊断比率对气溶胶中多环芳烃的潜在来源进行了调查，这些比率反映了柴油和汽油发动机等来源，不过煤炭燃烧和液化石油气等其他来源也有贡献。
