摘要

Since 1 January 2017, ships berthed at the core ports of three designated "domestic emission control areas" (DECAs) in China should be using fuel with a sulfur content less than or equal to 0.5 %.In order to evaluate the impacts of fuel switching, a measurement campaign (SEISO-Bohai) was conducted from 28 December 2016 to 15 January 2017 at Jingtang Harbor, an area within the seventh busiest port in the world.This campaign included meteorological monitoring, pollutant monitoring, aerosol sampling and fuel sampling.During the campaign, 16 ship plumes were captured by the on-shore measurement site, and 4 plumes indicated the usage of high-S_F (S_F refers to the sulfur content of marine fuels).The average reduction of the mean ΔNO_x=~1SO_2 ratio from high-sulfur plumes (3.26) before 1 January to lowsulfur plumes (12.97) after 1 January shows a direct SO2 emission reduction of 75 %, consistent with the sulfur content reduction (79 %).The average concentrations of PM2.5 (particulate matter with a diameter less than 2.5 μm), NO_x , SO_2, O_3 and CO during campaign were 147.85 μgm~(-3), 146.93, 21.91, 29.68 ppb and 2.21 ppm, respectively, among which NO_x reached a maximum hourly concentration of 692.6 ppb, and SO_2 reached a maximum hourly concentration of 165.5 ppb.The mean concentrations of carbonaceous and dominant ionic species in particles were 6.52 (EC-elemental carbon), 23.10 (OC-organic carbon), 22.04 (SO_2~-4),25.95 (NO_3~-) and 13.55 (NHC_4) μgm~(-3).Although the carbonaceous species in particles were not significantly affected by fuel switching, the gas and particle pollutants in the ambient air exhibited clear and effective improvements due to the implementation of low-sulfur fuel.Comparison with the prevailing atmospheric conditions and a wind map of SO_2 variation concluded a prompt SO_2 reduction of 70% in ambient air after fuel switching.Given the high humidity at the study site, this SO_2 reduction will abate the concentration of secondary aerosols an
