Wherein P and Port emission calculation result, NO _X is at sea 18,155 ton per year, SO _2- is a 9,094 ton per year, the annual 1904 tons CO, PM ₁₀ has been discharged is 1,229 tons per year. Further, in the land NO _X is 1,172 ton per year, SO _2- annual 118 tons, 249 tons per year is CO, PM ₁₀ has been discharged is 73 tons per year.

Referring to FIG. 13 , the port air pollution emission management apparatus 10 may calculate the total port emission amount by adding the emission amount of the maritime sector and the emission amount of the land sector with respect to the arbitrarily set I port. In I wherein Harbor emission calculation result, marine NO _X is 6,995 ton per year, SO _2- year is 3270 tons, 727 tons per year is CO, PM ₁₀ has been discharged is 447 tons per year. Further, in the land NO _X is 7,574 ton per year, SO _2- year is 3280 tons, 863 tons per year is CO, PM ₁₀ has been discharged is 487 tons per year.

In addition, the port air pollution emission management apparatus 10 may estimate the navigation route of the ship by displaying the location of the previous ship together with the location of the current ship according to the movement of the ship. In addition, the port air pollution emission management device 10 can visually detect a vessel with high emission through the emission display and can estimate the vessel's navigation route, so that the emission value can be analyzed.

Referring to FIG. 15 , the apparatus 10 for managing air pollution in the port may graphically display the amount and concentration of air pollutants discharged from the sea or land of the port by diffusion modeling. The port air pollution emission management apparatus 10 may display the discharge amount and concentration in various ways of at least one of a shape, a size, and a color of a figure.
