Review: Particle number size distributions from seven major sources and implications for source apportionment studies

摘要: Abstract The particle number size distribution (PNSD) of airborne particles not only provides us with information about sources and atmospheric processing particles, but also plays an important role in determining regional lung dose. As a result, urban their distributions have received much attention rapid increase publications recent years. object this review is to synthesise analyse existing knowledge on environments focus concentration distribution. This study briefly reviews the characterization PNSD from seven major including traffic emissions, industrial biomass burning, cooking, transported aerosol, marine aerosol nucleation. It then discusses physical processes such as coagulation or condensation which strong influence PNSD. Finally, implications datasets for source modelling are discussed. Based review, it concluded that concentrations, modal structures temporal patterns strongly influenced by identified main environments. Information derived beginning play apportionment studies.
