Apportionment of Residential Indoor Aerosol, VOC, and Aldehyde Species to Indoor and Outdoor Sources

摘要

The average concentrations of a large number of fine particle aerosol, VOC and aldehyde species measured in ten Boise, ID residences in wintertime have been apportioned according to their contributions from all inside sources and all outside sources. The method depends on the availability of average concentrations measured outside each residence during the same sampling periods used for the inside measurements, and on the ability to identify one or more species that have negligible indoor sources.
