船舶废气中的有机污染物对沿海地区的健康和空气质量有重大影响;还迫切需要对其进行分析。目前对船舶有机污染物的研究尚不多见，尤其是在我国。因此，本研究对我国15艘不同类型、不同燃料的船舶在不同工况下排放的PM中的21种多环芳烃和29种正构烷烃进行了检测。结果表明：（1）可识别有机物占PM的0.15%~23.3%;∑ 16多环芳烃基于燃料的排放因子（EFs）范围为0.095至5.80 mg（kg燃料）-1，与轻型柴油船相比，低发动机功率渔船和重质燃油（HFO）训练船的数值较高。∑正构烷烃的EFs范围为5.22至1589毫克（千克燃料）-1，与其他船只相比，低发动机功率的渔船具有更高的值。(2)多环芳烃以Pyr、Flua、Phe和Cr等中等分子量组分为主，C15~C33正构烷烃占总正构烷烃的97%以上。(3)典型多环芳烃与正构烷烃比值特征值具有典型的油燃烧源诊断特征。多环芳烃和正构烷烃的特征谱和诊断特征可以为未来的源解析提供更精确的结果。(4)此外，船舶排放的颗粒物中的多环芳烃对健康的影响不可忽视。
Organic pollutants from ship exhaust have significant health and air quality impact in coastal areas; their profiles are also in urgent need. Studies on organic pollutants from ships are still rare, especially in China. Therefore, 21 PAHs and 29 n-alkanes in PM emitted from 15 ships with different types and fuels under different operating modes in China were tested in this study. The results showed that: (1) Identified organic matters accounted for 0.15%–23.3% of PM. Fuel-based emission factors (EFs) for ∑16PAHs ranged from 0.095 to 5.80 mg (kg fuel)−1, with low-engine-power fishing boats and heavy fuel oil (HFO) training ship had higher values compared with light diesel vessels. EFs for ∑n-alkanes ranged from 5.22 to 1589 mg (kg fuel)−1, with low-engine-power fishing boats had higher values compared with other vessels. (2) The dominant PAHs were medium molecular weight components of Pyr, Flua, Phe, and Chr. N-alkanes from C15 to C33 accounted for more than 97% of the total n-alkanes. (3) Ratios of typical PAHs and n-alkanes parameters in this study showed typical diagnostic characteristics of oil combustion source. Profiles and diagnostic characteristics of PAHs together with n-alkanes could provide a more precise source apportionment result in the future. (4) Besides, PAHs in PM emitted from ships inferred non-ignorable health influence.
