摘要: 使用单颗粒气溶胶质谱仪对烟台市3类典型船舶排放的源谱特征进行了分析,结果表明:船用柴油燃烧排放的气溶胶单颗粒以OCEC类别为主;而重油燃烧中含FeVKNa等金属元素的类别占比较大,其中含V颗粒占比最大,且粒径主要集中在0.5 ~ 1.1 μm 段;而含SiFeKPb等颗粒主要分布在0.8 ~ 1.4 μm粒径段。以含V颗粒作为船舶排放示踪物,对烟台市5个典型站点空气质量受船舶排放影响的分析显示:5站点均明显受到船舶排放的影响,春、夏季影响明显高于秋、冬季;百盛商城和万润化工两个距港口最近的监测点受船舶排放影响最大,春、夏季特定条件下含V颗粒占比接近40%。基于统计数据对烟台市船舶排放PM2.5进行估算,2017年烟台市内河和沿海船舶PM2.5的排放量约为463.6 t,与机动车尾气排放量相当,因此需要进一步重视船舶尾气排放对本地大气颗粒物的影响。

Abstract: Single-particle aerosol mass spectrometer (SPAMS) was used to analyze the source features of 3 typical ship emissions in Yantai. The results showed that particle classes emitted by marine diesel oil were mostly composed of organic carbon (OC) and elemental carbon (EC), while those emitted by heavy fuel oil contained larger number of metal-containing particles such as Fe, V, K and Na. V-containing particle classes accounted for the largest proportion in heavy fuel oil emission, and were mainly concentrated in the small particle size range of 0.5~1.1 μm, while the metal-containing particles such as Si, Fe, K, and Pb were mainly distributed in larger size range of 0.8~1.4 μm. Based on the results, the V-containing particles were used as ship-emission tracer to study the impact of ship emissions on the air quality of 5 typical sites in Yantai. The results revealed that the five sites were obviously affected by ship emissions especially in spring and summer. The two sites Parkson Mall and Wanrun Chemical were the closest to the port, and suffered the most from the ship emissions. Under specific conditions in spring and summer, the V-containing particles proportion could reach up to 40%. Based on the statistical data, the PM2.5 emitted from inland and coastal ships in Yantai City were estimated to be 463.6 t in 2017, which was of the same order of magnitude as vehicle emission. Further attention should be paid to the impact of ship exhausts on local air quality.

Key words: single particle aerosol mass spectrometry, PM2.5, source profile, V-containing particle, ship emission
