为了解轮渡空气的颗粒物污染状况,改善乘客和工作人员的环境,采用美国Fluke 985粒子计数器对上海黄浦江轮渡“东金线”的颗粒物污染状况进行实测,分析粒径为0.30~0.49 μm,0.50~0.99 μm,1.00~1.99 μm,2.00~4.99 μm,5.00~9.99 μm,≥10.00 μm六种范围颗粒物的时空分布特征、影响因素以及轮渡污染的严重性,并对轮渡整体的颗粒物平均浓度进行预测.结果表明:轮渡二层露台的颗粒物浓度往往较高,人流量对粒径较粗的颗粒物影响较为明显;一层里舱和二层里舱的主要污染物为粒径较大(5.00~9.99 μm, ≥10.00 μm)的颗粒物,二层露台主要污染物为粒径较细(0.30~0.49 μm,0.50~0.99 μm,1.00~1.99 μm,2.00~4.99 μm)的颗粒物.

In order to understand the particulate matter pollution of the ferry air and improve the environment of passengers and staff, the particulate matter pollution of the “East Golden Line” of the Huangpu River Ferry in Shanghai was measured by the Fluke 985 particle counter of the United States. The temporal and spatial distribution characteristics, influencing factors and the severity of ferry pollution of particulate matter with particle sizes of 0.30~0.49 μm, 0.50~0.99 μm, 1.00~1.99 μm, 2.00~4.99 μm, 5.00~9.99 μm and more than 10.00 μm were analyzed, and the average concentration of particulate matter in the whole ferry was predicted. Results show that the concentration of particulate matter in the second deck terrace of ferry is often high, the influence of human flow rate on coarse particle size is more obvious. The main pollutants in the first and second inner cabins are particles with larger size (5.00~9.99 μm, ≥10.00 μm), and the main pollutants in the twotier terrace are particles with finer size (0.30~0.49 μm,0.50~0.99 μm,1.00~1.99 μm,2.00~4.99 μm).
