Micro-Morphology Character and Mineral Composition of PM₁₀ in Nanjing Typical Areas

Abstract:

The goal of this paper was to study the micro-morphology and mineral composition of PM10 in Nan jing typical areas were studied using scanning electronic microscopy and energy dispersive spectrometer (SEM/EDS). Samples were collected as PM10 for 24 h using high-volume air sampler from Dachang and Shanxilu area. The SEM/EDS analysis showed that mineral particles with regular shapes were popular in PM10 in Dachang District, and mineral particles with irregular shapes were popular in PM10 in Shanxilu area respectively. The composition of mineral particles with regular shapes were mainly carbon ates, sulphates, and aluminosilicates, while mineral particles with irregular shapes were mainly soot aggregates, biomass and primitive minerals.
