武汉市内河船舶气态污染物的排放量估算研究OA

With the sustained growth of global economy,the shipping industry plays a pivotal role in logistics.The environmental and health impacts of ship exhaust emissions cannot be overlooked.This study focuses on inland water vessels in Wuhan City,investigating gaseous pollutant emissions through field monitoring.The findings reveal that the concentration of SO2 emissions from inland water vessels in Wuhan ranges from 2.30 to 63.10 mg/m3,with the highest SO2 emission concentration observed in tourist vessels under upstream navigation conditions.The concentration of NOx emissions spans from 188 to 2 432 mg/m3.The total volatile organic compounds(TVOCs)emission concentrations in the exhaust gas of four monitored vessels range from 100 to 700 mg/m3,also reaching their highest levels under upstream navigation conditions.This is likely due to the increased power required by the vessels to overcome the resistance of the water flow,leading to higher engine loads and consequently,increased TVOC emissions.Finally,the total emissions of pollutants from inland water vessels in Wuhan were estimated,and a comparison was made between the vessel emission data from 2017 and 2023.The overall emissions of gaseous pollutants from vessels in 2023 showed a certain degree of reduction compared to 2017.The results of this study provide a scientific basis for formulating air pollutant emission control measures for inland water vessels in Wuhan and offer valuable references for optimizing ship pollution control strategies.
