A global three-dimensional Lagrangian chemistry-transport model STOCHEM is used to describe the European regional acid deposition and ozone air quality impacts along the Atlantic Ocean seaboard of Europe, from the SO2, NOx, VOCs and CO emissions from international shipping under conditions appropriate to the year 2000. Model-derived total sulfur deposition from international shipping reaches over 200 mg S m(-2) yr(-1) over the southwestern approaches to the British Isles and Brittany. The contribution from international shipping to surface ozone concentrations during the summertime, peaks at about 6 ppb over Ireland, Brittany and Portugal. Shipping emissions act as an external influence on acid deposition and ozone air quality within Europe and may require control actions in the future if strict deposition and air quality targets are to be met.
一个全球三维拉格朗日化学传输模型STOCHEM被用于描述欧洲大西洋沿岸地区的酸沉降和臭氧空气质量影响，这些影响源于2000年条件下国际航运产生的二氧化硫、氮氧化物、挥发性有机化合物和一氧化碳排放。模型得出，在不列颠群岛和布列塔尼半岛的西南方向，国际航运产生的总硫沉降量超过200毫克硫每平方米每年。夏季，国际航运对地表臭氧浓度的贡献在爱尔兰、布列塔尼半岛和葡萄牙达到峰值，约为6 ppb。航运排放是对欧洲酸沉降和臭氧空气质量的外部影响，如果要实现严格的沉降和空气质量目标，未来可能需要采取控制措施。
