"Sources and Atmospheric Chemistry of Selected Volatile Organic Compounds"

Volatile organic compounds (VOCs) undergo photochemical reactions in the presence of nitrogen oxides (NOx) and sunlight in the atmosphere to generate ozone (smog). Because of uncertainties in ozone-precursor emissions and the complexity of their chemistry, this process is still not fully understood. This presentation will focus on two projects in the atmospheric chemistry group at Fresno State. In the first project, emissions of VOCs from Central California dairies have been investigated. These facilities are believed to be a major source of VOCs in the region, but their emissions are still poorly characterized. We have measured VOC emissions from several dairies using a variety of approaches and instruments. The results of these measurements and their consequences for regional air quality will be discussed. In the second project, we have studied aspects of the atmospheric chemistry of isoprene, a VOC emitted in large quantities by plants and trees. Isoprene 4,1-hydroxy nitrate, an intermediate in the atmospheric degradation of isoprene, was synthesized and its gas phase chemistry with various atmospheric oxidants was investigated in a photochemical reactor. The potential implications of the atmospheric chemistry of this compound will be described.
