Modelling Exhaust Emission From Vessels In The Gulf Of Gdańsk Area

The area of the Gulf of Gdańsk, just like port towns and coastal regions, is vulnerable to pollution contained in the exhaust gases of industrial plants, power plants, vehicles and harmful compounds contained in exhausts of vessels. In order to determine the share of vessels in polluting atmospheric air and to counteract the harmful effects of toxic compounds in marine engine exhausts it is necessary to know the values of those compounds’ emission from particular vessels, which is possible by knowing the movement parameters of vessels, the values of concentrations of particular compounds for these parameters and the atmospheric conditions in the region of their occurrence. The object of balancing emission of pollution contained in the exhausts from engines propelling vessels are the processes of global emission, averaged in a sufficiently long time period, which is determined first of all by the effi-ciency of averaging the variable conditions of the objects’ operation. Due to the impossibility of making emission measurements on vessels in the region of research, it is necessary to work out suitable models of estimating emission of toxic compounds, based on proper measurement tests simulating navigational conditions in the Gulf of Gdańsk as well as mathematical models. The work presents conditions related to modelling the emission of exhaust compounds from vessels engines in the region of the Gulf of Gdańsk, with particular consideration to estimating the values of toxic compounds concentration.
