This research is investigating the gas-phase formation pathways of organic acids, hydrogen peroxide, organic peroxides and other multifunctional oxygenated and nitrated compounds in the atmosphere. The P.I. is developing a novel solid phase microextraction technique (SPME) which, combined with gas chromatography/mass spectrometry, will help determine important reaction pathways for the production of secondary aerosols in the atmosphere. This research is of critical importance to understand the biochemical effects associated with atmospheric aerosols and sources of airborne acidity in the environment.

本研究探讨大气中有机酸、过氧化氢、有机过氧化物及其他多功能含氧和硝化化合物的气相生成途径。 私家侦探正在开发一种新的固相微萃取技术（SPME），该技术与气相色谱/质谱法相结合，将有助于确定大气中二次气溶胶产生的重要反应途径。 这项研究对于了解与大气气溶胶和环境中空气酸性来源相关的生物化学效应至关重要。
