Partitioning Of Volatile Organic Compounds Into The Multiple Environmental Compartments, Jeonghyeon Ahn

Theses and Dissertations

Volatile organic compounds (VOCs) dominate the class of pollutants that accumulate in the atmosphere and indoors. Partitioning coefficient is a measure of a compound’s ability to distribute between two phases. Assessing the partitioning of VOCs is essential to determine their transport, fate, behavior, and adverse environmental and health impacts across multiple environmental compartments. Studies on VOC partitioning have been limited because discriminating the small mass fraction of VOCs in aerosol particles is difficult to quantify. The partitioning of VOCs into soil, air, and aerosol particle phases was investigated under dynamic laboratory conditions. A bench-scale system that precisely controlled the relative …
