Hydroperoxide, Nitrate, and Epoxide Chemistry of Biogenically-produced Alkenes

这项研究是一项名为SOAS（南方氧化剂和气溶胶研究）的广泛社区实验的组成部分，该实验旨在进一步研究美国东南部大气环境下植物排放物（生物源性挥发性有机化合物；BVOCs）的光氧化。该项目计划于2013年夏季在阿拉巴马州进行合作实地实验，研究主要生物烯烃及其氧化产物的光化学性质。该地点被选为植被中的大量BVOCs与发电厂和其他人为来源排放的不同数量的NOx和SOx氧化剂混合在一起的区域，涵盖了这些化合物所表现出的广泛的自然反应性。除了通过臭氧形成光化学烟雾外，BVOCs随后的氧化产物可能会增加次生气溶胶的大气负担，这与区域气候强迫有关。气候变化对人类健康和福祉的影响使对这些化合物和颗粒的研究成为当前大气化学研究的一个关键方面。

This research is a component of a broad community experiment named SOAS (Southern Oxidant and Aerosol Study) designed to further investigate the photo-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 photochemistry of the dominant biogenic alkenes and their oxidation products, during a collaborative field experiment planned for summer, 2013 in Alabama. This site was chosen as a region where substantial BVOCs from vegetation mix with variable amounts of NOx and SOx oxidants emitted from power generation sites and other anthropogenic sources, covering a wide range of the natural reactivity exhibited by these compounds. As well as the generation of photochemical smog through ozone formation, the subsequent oxidation products from BVOCs may contribute to the atmospheric burden of secondary aerosols, which have been implicated in regional climate forcing. Both the impacts on human health and human well being through climate change make the study of these compounds and particles a key aspect of current atmospheric chemical investigation.
