Abstract

In order to effectively manage the pollution from ships in ports, it is very necessary to understand the quantity and characteristics of the emissions from port pollution sources, so that more scientific management measures can be provided.This paper mainly analyzes the three pollution emission sources of Yangshan Port, namely port machinery, transport vehicles and ships, and uses the emission factor method to estimate and establish the air pollution emission inventory of Yangshan Port in 2021.The results show:1) The emissions of pollutants SO2, PM, NOx, CO, and VOCs are 5011t, 1252t, 27,560t, 1670t, and 2150t, respectively;2) Ships are the largest source of pollution, with container ships providing the largest pollution contribution among the different ship types, accounting for 38%;3) The main engine and auxiliary engines, as the main source of pollution from ships, accounted for 40% and 42% of the total amount of pollutants, respectively; the slow-speed state accounted for the highest proportion of pollution discharged in the four operating states, at 41%.
