    A Comparison Study of Chemical Compositions and Sources of PM1.0 and PM2.5 in Hanoi by Pham Duy Hien, Vuong Thu Bac, Nguyen Thi Hong Thinh, Ha Lan Anh, Duong Duc Thang, Nguyen The Nghia

    Published 2021-07-01
    “…Whereas LRT aerosols, coal fly ash, and primary particulate vehicular emissions mainly occurred in the PM1.0, resuspended road dust and biomass-burning fly ash tended to appear in the PM1.0–2.5; hence, we can characterize the anthropogenic emissions in this area by examining the profile of the PM1.0 rather than the PM2.5. Additionally, air masses with inland trajectories originating in northern China and countries northwest and southwest of Vietnam contained more ammonium, sulfate, and BC than those that passed over the East Sea. …”
