Title	Residential indoor and outdoor air pollution.
Date	1984
Abstract	The polycyclic aromatic hydrocarbon (PAH) content of ambient air at several locations is described. The indoor sites examined included those having woodstoves, fireplaces, and kerosene heaters as supplements to oil heat, as well as one test home which employed a woodstove as its sole source of heat. The PAH levels in homes with woodburning devices were consistently higher than those levels found outdoors. Air infiltration measurements using sulfur hexafluoride as a tracer gas were taken in all homes. Other pollutants monitored at the selected sites included total suspended particulates (TSP), respirable particulates (RP, d <2.5 um>, nitrogen dioxide, and carbon monoxide. In the majority of cases, outdoor samples were taken to correspond with the indoor ones, so as to obtain indoor to outdoor ratios (I/O). Various northern New England outdoor environments where wood is a major fuel were sampled in both the summer and winter months. Weekly samples were taken at a Hanover, New Hampshire site during 1983 to obtain an annual profile of selected PAH concentrations and TSP levels. Another site characterized was the summit of Mt. Ascutney, a location with an elevation of 3144 feet and a distance of twenty miles from Hanover. The PAH concentrations at a distance of twenty miles from Hanover. The PAH concentrations at this site enabled us to confirm the hypothesis that the great majority of the PAH found in the air of the Upper Valley region are enerated locally and are not brought into the area by long-range transport. Evaporative losses of PAH from filters during both indoor and outdoor air sampling are confirmed. Polyurethane foam was placed in series behind quartz fiber and teflon-coated glass fiber filters. The expected correlations with molecular weight and temperature were found; as the molecular weight increases, less PAH is lost, and, as the temperature increases, more PAH is lost. The analytical method for extracting PAH from filters was modified for polyurethane foam and is described. Levoglucosan, a carbohydrate known to be a major decomposition product of cellulose and wood, was quantitatively determined at various sites, and evaluated to determine its applicability as a maker for woodsmoke. Correlations between the concentrations of this compound and various PAH are examined.
