Heavy metal aerosol particles were first measured with Single Particle Aerosol Mass Spectrometry (SPAMS) in north suburb of Nanjing from January to December, 2013. Using the ART-2a neural network algorithm, we studied the chemical characteristics of aerosol particles and found that the main sources of heavy metal aerosols in Nanjing were industrial emissions, biomass burning, traffic emissions, fuel combustion and dust, accounting for 35.7%, 34.45%, 13.6%, 11.03% and 4.07% respectively. Pb, Cd and Cr-containing aerosols mainly came from industrial emissions. Cu, Co and Hg-containing aerosols mainly came from biomass burning. V, Zn and Ba-containing aerosols mainly came from traffic emissions. As and Ni-containing aerosols mainly came from fuel combustion.
2013年1月至12月，首次在南京北郊利用单颗粒气溶胶质谱仪（SPAMS）对重金属气溶胶颗粒进行了测量。采用ART-2a神经网络算法，研究了气溶胶颗粒的化学特征，发现南京重金属气溶胶的主要来源为工业排放、生物质燃烧、交通排放、燃料燃烧和扬尘，分别占35.7%、34.45%、13.6%、11.03%和4.07%。含铅、镉和铬的气溶胶主要来自工业排放。含铜、钴和汞的气溶胶主要来自生物质燃烧。含钒、锌和钡的气溶胶主要来自交通排放。含砷和镍的气溶胶主要来自燃料燃烧。
