Chemical elemental analysis of dustfall particulate matter and identification of pollution sources at a habour area

In order to clarify the impact of dust generated during production operations at a coal port on the regional atmospheric environment, the dustfall particles from October 2021 to September 2022 were sampled. The chemical fractions of dustfall particles are determined and the seasonal distribution characteristics are analyzed. The study shows that the annual average content of total carbon (TC) of the dustfall particles is 45.10
