摘要: 大气气溶胶因其对气候和公众健康的影响而成为当今环境研究领域的中心课题.单颗粒分析是目前国际上大气气溶胶研究的一个前沿领域,该方法具有高的时间和空间分辨率,能够提供全颗粒物分析所无法提供的大量信息.利用自主研制的单颗粒气溶胶质谱仪(single particle aerosol mass spectrometer, SPAMS),对广东鹤山地区气溶胶进行在线分析.重点分析含金属颗粒的相关性、数浓度和可能的来源,并简单介绍该仪器的产业化情况.

关键词: 大气气溶胶, 单颗粒气溶胶质谱仪, 含金属颗粒物

Abstract: Atmospheric aerosol has become a key issue in environmental research due to its impact on climate and public health. In atmospheric aerosol research, single particle analysis has high temporal and spatial resolution, and is a leadingedge approach. It can provide far more information beyond the capacity of bulk particle analysis. Aerosol particles in Heshan City, Guangdong, are characterized online using a selfmade single particle aerosol mass spectrometer (SPAMS). Correlation, number concentration and possible sources of the particles that contain metallic substances are analyzed. Commercialization prospect of SPAMS is briefly discussed.

Key words: atmospheric aerosol, particle containing metallic substance, single particle aerosol mass spectrometer (SPAMS)
