| 摘 要： | 通过2013年1~12月使用在线单颗粒气溶胶质谱仪(SPAMS)在南京北郊对含有Cu、As、Pb、Cd、V、Co、Cr、Zn、Ni、Ba和Hg这11种重金属气溶胶粒子进行连续观测,并结合自适应共振理论神经网络算法(ART-2a)对其化学特征进行了分析,结果表明,南京北郊重金属气溶胶粒子来源按照化学组成特征可分为5类:工业排放(35.7%)、生物质燃烧(34.45%)、交通排放(13.6%)、化石燃料燃烧(11.03%)和矿尘(4.07%),其中,含Pb、Cd和Cr气溶胶粒子主要来源于工业排放,含Cu、Co和Hg气溶胶粒子主要来源于生物质燃烧,含V、Zn和Ba气溶胶粒子主要来源于交通排放,含As和Ni气溶胶粒子主要来源于化石燃料燃烧.

| Abstract: | 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. |
