Gas/particle partitioning of low-molecular-weight dicarboxylic acids at a suburban site in Saitama, Japan
Abstract Low-molecular-weight dicarboxylic acids (diacids) exhibit semivolatile behavior in the atmosphere, but their partitioning between the gaseous and particulate phases is still unclear. AnExpand
