船舶尾气排放对葛洲坝大气灰霾的影响初探

摘要

It is pointed out that the research on ship tail gas is starting in the study of the current haze.In this paper, the source of PM2.5 at the ship lock of Gezhou Dam was analyzed using the most advanced on-line single particle aerosol mass spectrometer (SPAMS0525).Combined with the material balance calculation of shipping emission, the contribution of shipping emission on the formation of haze was estimated to be 7%, which should be paid with more attention.%指出了目前对灰霾来源的研究中,对船舶尾气的研究目前正起步.采用目前国内最先进的在线单颗粒气溶胶质谱仪SPAMS0525对葛洲坝船闸处的细颗粒物PM2.5来源进行了解析监测,结合船舶污染物排放量的核算,得出了船舶尾气排放对灰霾形成有较大影响,贡献率约占7%的结论.
