Characteristics Of Atmospheric Dust Particles In Nanchang And Their Environmental Significance

With the usage of EPMA, this paper carries out a systematic study of atmospheric dust particles' shapes and components in Nanchang city. The results show that the atmospheric dust particles are various in shapes, and their major ingredients are mineral particles, calcite particles, massive dust aggregate and fly ash particles. The composition of particles in different functional zones is not alike, indicating different sources of particles. And the characteristics study of atmospheric dust particles can reveal atmospheric environmental features, which plays an essential role in city planning and air pollution controlling.
