Abstract

Marine pollution management requires identifying all sources of contaminants, yet shipping's role in marine contamination remains unexplored. To address this gap, we investigated shipping contribution to water and air pollutant loads in the Northern Adriatic Sea in 2018 and under two future scenarios. The approach integrated (i) modelled data of shipping-related emissions, (ii) load from tributaries, and (iii) land-based emissions to the atmosphere. The results showed that shipping significantly contributes to copper, zinc (from antifouling paints), nitrogen (from sewage and food waste), phenanthrene, and naphthalene (from scrubbers and bilge water) loads. Under an increased shipping traffic scenario by 2050, scrubber use reduces atmospheric emissions but increases water pollutants, while alternative fuels reduce air contaminants emission with no significant increase in water pollution. This study sets the foundation to apply water and air quality models to identify areas of concern and assess the environmental impacts of future shipping emission control strategies.

航运对亚得里亚海北部水和空气污染物排放的贡献——当前和未来情景

海洋污染管理需要确定所有污染源，但航运在海洋污染中的作用仍未得到探索。为了解决这一差距，我们调查了2018年和未来两种情况下北亚得里亚海航运对水和空气污染物负荷的贡献。该方法综合了(i)与航运有关的排放的模拟数据，（ii）支流的负荷，以及（iii）对大气的陆地排放。结果表明，航运对铜、锌（来自防污涂料）、氮（来自污水和食物垃圾）、菲和萘（来自洗涤器和舱底水）的负荷有很大贡献。在2050年航运量增加的情况下，洗涤器的使用减少了大气排放，但增加了水污染物，而替代燃料减少了空气污染物排放，但没有显著增加水污染。本研究为应用水和空气质量模型来识别关注领域和评估未来航运排放控制策略的环境影响奠定了基础。

期刊介绍： Marine Pollution Bulletin is concerned with the rational use of maritime and marine resources in estuaries, the seas and oceans, as well as with documenting marine pollution and introducing new forms of measurement and analysis. A wide range of topics are discussed as news, comment, reviews and research reports, not only on effluent disposal and pollution control, but also on the management, economic aspects and protection of the marine environment in general.
