摘要

Shanghai has become an international shipping center in the world. In this study, the multiyear measurements and the high resolution air quality model with houdy ship emission inventory were combined to determine the influence of ship emissions on urban Shanghai. The aerosol time-of-flight mass spectrometer (ATOFMS) measurements were carried out at an urban site from april 2009 to January 2013. During the entire sampling time, most of the half-hourly averaged number fiactions of primary ship emitted particles varied between 1.0- 10.0%. However, the number fraction could reach up to 50% during the ship plume cases. Ship-plume-influenced periods mually occurred in spring and summer. The simulation of Weather Research and Forecasting/Community Multiscale Air Quality model (WRF/CMAQ) with hourly ship emission inventory provided the highly time-resolved concentrations of ship-reated air pollutants during a ship plume case. It showed ships could contribute 20-30% (2-7 μg/m~3) of the total PM_(2.5) within tens of kilometers of coastal and riverside Shanghai during ship-plume-influenced periods. Our results showed that ship emissions have substantial contribution to the air pollution in urban Shanghai. The control measures of ship emission should be taken considering its negative environment and human health effects.
