This work is intended to assess the impact on local air quality due to atmospheric emissions from port area activities for a new port in project in the Mediterranean Sea. The sources of air pollutants in the harbour area are auxiliary engines used by ships at berth during loading/offloading operations. A fleet activity-based methodology is first applied to evaluate annual pollutant emissions (NO(X), SO(X), PM, CO and VOC) based on vessel traffic data, ships tonnage and in-port hotelling time for loading/offloading operations. The 3-dimensional Calpuff transport and dispersion model is then applied for the subsequent assessment of the ground level spatial distribution of atmospheric pollutants for both long-term and short-term averaging times. Compliance with current air quality standards in the port area is finally evaluated and indications for port operation are provided. Some methodological aspects of the impact assessment procedure, namely those concerning the steps of emission scenario definitions and model simulations set-up at the project stage, are specifically addressed, suggesting a pragmatic approach for similar evaluations for small new ports in project.
本工作旨在评估地中海某项目新港口区活动对当地空气质量的影响。港口地区的空气污染物来源是船舶在装卸作业时停泊时使用的辅助发动机。首先应用基于船队活动的方法来评估基于船舶交通数据、船舶吨位和装卸作业停泊时间的年度污染物排放（NO(X)、SO(X)、PM、CO 和 VOC）。然后应用三维 Calpuff 传输和扩散模型来评估大气污染物在地面水平的空间分布，包括长期和短期平均时间。最后评估港口区域内现行空气质量标准的达标情况，并为港口运营提供指示。特别针对项目阶段的排放情景定义和模型模拟设置步骤，讨论了影响评估程序的一些方法方面，为类似的小型新建港口的评估提供了一种实用方法。
