Particulate matter 2.5 (PM2.5), collected from ambient air in Fukuoka City, was analyzed by gas chromatography combined with multiphoton ionization mass spectrometry using an ultraviolet femtosecond laser (267 nm) as the ionization source. Numerous parent polycyclic aromatic hydrocarbons (PPAHs) were observed in a sample extracted from PM2.5, and their concentrations were determined to be in the range from 30 to 190 pg/m(3) for heavy PPAHs. Standard samples of nitrated polycyclic aromatic hydrocarbons (NPAHs) were examined, and the limits of detection were determined to be in the picogram range. The concentration of NPAH adsorbed on PM2.5 in the air was less than 900-1300 pg/m(3). Graphical Abstract ᅟ.
采集自福冈市环境空气中的细颗粒物2.5（PM2.5），采用以紫外飞秒激光（267nm）作为电离源的气相色谱-多光子电离质谱联用仪进行分析。在从PM2.5中提取的样品中观察到了多种母体多环芳烃（PPAHs），重质PPAHs的浓度测定范围为30至190 pg/m³。对硝化多环芳烃（NPAHs）的标准样品进行了检测，检测限确定在皮克范围内。空气中吸附在PM2.5上的NPAH浓度小于900 - 1300 pg/m³。图形摘要ᅟ。
