Several studies indicate that short-sea shipping is an important source of air pollution for coastal areas and port cities. This paper reports results of a non-reactive particles dispersion model and a new set of experiments implemented for the Channel of Procida (Italy), an area with a high signal-to-noise ratio, due to intense marine traffic and low background pollution. The model successfully predicts particle number concentrations but underestimates PM2.5 data. Model and experiments show that thanks to the EU policies on marine fuels, the Channel of Procida already has good air quality levels. Besides, the paper demonstrates that fostering the use of LNG or methanol or the application of an exhaust-gas-cleaning-system may allow reducing particles emissions well above 90%. The reliability of control strategies and the benefits for the population suggest that the introduction of regulations on particles emissions for ships can be a realistic option for the future environmental policy agenda.

近海航运对沿海地区颗粒物浓度的贡献:影响和缓解

多项研究表明,近海航运是沿海地区和港口城市空气污染的重要来源。本文报告了非反应性粒子分散模型的结果和针对 Procida 海峡(意大利)实施的一组新实验的结果,该区域由于海上交通繁忙和背景污染低而具有高信噪比。该模型成功地预测了粒子数浓度,但低估了 PM 2.5数据。模型和实验表明,得益于欧盟政策在船用燃料方面,普罗奇达海峡已经具有良好的空气质量水平。此外,该论文表明,促进使用 LNG 或甲醇或应用废气清洁系统可以使颗粒物排放量减少 90% 以上。控制策略的可靠性和对民众的好处表明,引入船舶颗粒物排放法规可能是未来环境政策议程的现实选择。
