英文摘要	Controlling NOx emission from offshore ships is one of the important means to improve air quality in port cities. The quantitative impact of NOx emission from ships on air quality is limited by the lack of NOx emission factors of localized ships in China, and it is difficult to improve in a short term. In order to provide quantitative source apportionment for air pollution control, this project will choose about 20-25 test vessels according to attribute information of ships, such as engine speed, ship age, engine power, fuel type, and etc in Bohai Sea, and measure the nitrogen isotopic composition of NOx (δ 15N-NOx) in operation states of cruising, cruising at low speed, maneuvering and berthing. The project will screen main parameters influencing the change of δ 15N-NOx from the ship property and operation status data, and use the main influence parameters to express the change of δ 15N-NOx . This project will calcu late the representative value of δ 15N-NOx at typical berthing / maneuvering (Tianjin new port) and navigation (channel) area based on the main influence parameters of ships over Bohai Sea by automatic identification system. Taking PM2. 5 samples near Tianjin port and main channel of Bohai Sea as examples, this project will use isotopic traceability model and receptor model to quantitatively evaluate the impact of NOx emission from ships on air quality. The finding will provide theoretical basis for understanding the source of air pollutions from the perspective of isotopes.
