Description:
The average concentrations of a large number of VOC and aldehyde species measured in ten Roanoke, Virginia residences in wintertime have been apportioned according to their contributions from all inside sources and all outside sources. he two category apportionment was accomplished through the use of the single chamber mass balance indoor air quality model given by Dockery and Spengler. hile the indoor concentration of some VOC's appeared entirely due to infiltration, most aldehydes had substantial indoor sources. ome homes exhibited very large indoor sources for a few VOC species and two homes appeared contaminated by gasoline vapors. he overall contribution of indoor and outdoor sources to the concentrations of VOC's inside the Roanoke homes is similar to that observed in Boise, ID in a previous study.
