采用高效液相色谱法、化学发光法、荧光法和无焰原子吸收光谱法测定了日本长崎市12个月的空气污染物，如多环芳烃（PAHs）、其硝化衍生物（NPAHs）和空气颗粒中的一些金属。总PAHs平均浓度为18.24 (4.07-41.54)ng/m3， NPAHs平均浓度为0.91 (0.23-4.10)pg/m3， Pb平均浓度为7.95 (1.71-16.31)ng/m3， Mn平均浓度为11.56 (3.35-24.96)ng/m3， Ni平均浓度为3.79 (0.97-14.71)ng/m3 （n=136）。长崎市区经毒性当量因子调整后的总多环芳烃浓度为2.33 ng/m3。冬季总PAHs和NPAHs浓度高于夏季。在周变化研究中，总PAHs和NPAHs浓度以及交通量表现出相似的趋势，均在工作日较高，周末较低。总多环芳烃和非多环芳烃与交通量的相关系数分别为0.781和0.818。这些结果表明，机动车可能是城市地区NPAHs和PAHs的主要来源之一。
Air pollutants such as polycyclic aromatic hydrocarbons (PAHs), their nitrated derivatives (NPAHs), and some metals on airborne particles in Nagasaki city, Japan were determined over a period of 12 months by high-performance liquid chromatography with chemiluminescence, fluorescence and flameless atomic absorption spectrometry. The average concentrations (range) were 18.24 (4.07–41.54) ng/m3for total PAHs, 0.91 (0.23–4.10) pg/m3for NPAHs, 7.95 (1.71–16.31) ng/m3for Pb, 11.56 (3.35–24.96) ng/m3for Mn and 3.79 (0.97–14.71) ng/m3for Ni (n=136). The toxic equivalency factors adjusted concentration of total PAHs determined in Nagasaki city area was 2.33 ng/m3. Concentrations of total PAHs and NPAHs in winter were higher than those in summer. In a weekly variations study, total PAHs and NPAHs concentrations, as well as traffic volume showed a similar tendency with all values higher during weekdays and lower at the weekend. The correlation coefficients between total PAHs or NPAHs and traffic volume were 0.781 and 0.818, respectively. These results suggested that one of the main sources for NPAHs and PAHs in a city area might be motor vehicles.
