Measurements of Amines during the Southern Oxidant and Aerosol Study (SOAS) Field Campaign

这项研究是名为SOAS(南方氧化剂和气溶胶研究)的广泛社区实验的组成部分，旨在进一步调查美国东南部大气环境中植物排放的氧化(生物挥发性有机化合物；BVOCs)。该项目将调查有机胺对二次有机气溶胶(SOA)形成过程的影响。胺和氨是大气中的主要有机碱化合物。它们总是存在于气溶胶颗粒中，并可能通过其氧化产物的缩合或通过盐类与更酸性的气溶胶颗粒形成而促成SOA的形成。胺及其氧化产物可能会对健康造成不利影响，并直接影响空气质量和能见度。目前，缺乏对气相胺的测量，特别是在美国东南部的生物成因环境中。该项目将在2013年SOAS宣传活动期间使用快速响应化学电离质谱仪(CIMS)对胺进行地面测量，以更好地研究胺对二次气溶胶形成过程的影响。

This research is a component of a broad community experiment named SOAS (Southern Oxidant and Aerosol Study) designed to further investigate the oxidation of the emissions (biogenic volatile organic compounds; BVOCs) of plants in the context of the atmospheric environment of the Southeast United States. The project will investigate the effects of organic amines on secondary organic aerosol (SOA) formation processes. Amines, along with ammonia, are the dominant organic base compounds in the atmosphere. They are invariably present in aerosol particles, and may contribute to SOA formation through condensation of their oxidation products, or by the formation of salts with more acidic aerosol particles. Amines and their oxidation products may have adverse health effects and directly impact air quality, and visibility. At present, measurements of gas-phase amines, especially in biogenic environments in the southeastern United States, are lacking. This project will make ground-based measurements of amines with a fast-time response chemical ionization mass spectrometer (CIMS) during the 2013 SOAS campaign to better investigate the effects of amines on secondary aerosol formation processes.
