The article presents the issues of modeling the emission of harmful compounds contained in the exhaust gases of marine engines and the dispersion of these compounds in the atmosphere. There are many models describing these phenomena at various spatial scales; however, a frequent problem is the inability to obtain the necessary input data, the necessity of using major simplifications, and the failure to account for all variables that have a direct or indirect impact on the described phenomena. There is a need to standardize methods for determining emission factors of harmful compounds and their dispersion in the air. This article presents an attempt to develop a methodology for modeling the emission and dispersion of harmful components of ship exhaust gases, taking into account the photochemical transformations of the chemical compounds studied.INTRODUCTION
The subject of many scientific publications around the world is the issue of the impact of harmful compound emissions present in ship exhaust gases on atmospheric air quality, both globally (e.g., [2], [3], [4], [5], [9]), regionally (e.g.
[6], [10], [11], [19]), and locally, e.g., in the areas of large seaports (e.g., [7], [13], [17]).
It is estimated that almost 70% of global harmful compound emissions from marine vessels occur within 400 km of land, with a portion reaching land areas.
Compression-ignition internal combustion engines contribute to an increase in SOx immission in many coastal areas by more than 5% to about 30% [2].
The results of studies on the impact of ship exhaust emissions on human health indicate that every year about 60,000 people worldwide die prematurely due to respiratory diseases caused by air pollution from ship exhaust [4]. The highest mortality rates, mainly due to heart and lung failure, are found in water areas characterized by high ship traffic intensity, in particular the English Channel, the east coast of the United States of America, and Southeast Asia.
The Baltic Sea is a water area with intense ship traffic, mainly consisting of short sea voyages. It constitutes a so-called (…)
