“…Daily air exchange was measured in each of the homes using perfluorocarbon tracer gas (Dietz and Cote 1982). Four sources of the tracer gas and one activated carbon receptor unit were installed on the main floor of the home.…”

Concentrations of airborne continuous fine particulate matter or (PM 2.5 ), black carbon (BC), and ultrafine particles (UFP) were continuously measured over 5 days in winter and summer both indoors and outdoors at residences for forty-eight adults in 2005 and forty-seven asthmatic children in 2006. During 2006, personal concentrations of PM 2.5 were also measured continuously. All 4 continuous instruments employed performed well both in laboratory and field conditions. Mean outdoor concentrations of PM 2.5 , BC, and UFP were significantly higher than either indoor or personal concentrations. Air exchange rates were low (median value only 0.2/h), there was widespread use of central forced air and high-quality furnace filters. Outdoor concentrations of all particle-related pollutants showed overnight decreases followed by increases during the morning rush hours. Afternoon concentrations increased for UFP and decreased for BC, with PM 2.5 staying about the same. Between 5:00 pm and 7:00 pm, indoor UFP and PM 2.5 concentrations exceeded their mean daily values by 160% and 60%, respectively, suggesting that cooking is an extremely important source for these two pollutants. However, BC values did not increase at these hours. The highest indoor-outdoor ratios were observed for UFP suggesting that indoor sources were relatively more important for UFP than for other particle components. BC measurements in Windsor agreed moderately well (R 2 = 41%) with an independent measure of elemental carbon (EC) in Detroit. This large residential air pollution study has provided data making it possible to identify short-term variations and possible sources that can influence the relationships between pollutants and environments.

The US Environmental Protection Agency's (US EPA) Detroit Exposure and Aerosol Research Study (DEARS) deployed a total of over 2000 nitrogen dioxide, NO 2, passive monitors during 3 years of field data collections. These 24-h based personal, residential outdoor and community-based measurements allowed for the investigation of NO 2 spatial, temporal, human and environmental factors. The relationships between personal exposures to NO 2 and the factors that influence the relationship with community-based measurements were of interest. Survey data from 136 participants were integrated with exposure findings to allow for mixed model effect analyses. Ultimately, 50 individual factors were selected for examination. NO 2 analyses revealed that season, exposure to environmental tobacco smoke and residential gas appliances were strong influencing factors. Only modest associations between community-based measures of nitrogen dioxide and personal exposures impacted by various exposure factors for heating (r ¼ 0.44) or nonheating seasons (r ¼ 0.34) were observed, indicating that use of ambient-based monitoring as a surrogate of personal exposure might result in sizeable exposure misclassification.

“…Enrichment for active sampling is also possible (Cheong & Riffat, 1995;Dietz & Cote, 1982;Dietz et al, 1986;Krooß et al, 1997;Mailahn et al, 1989;Salmon et al, 2000). Since these compounds, unlike SF 6 , adsorb well on activated carbon or Tenax they are frequently used in field studies (surveys) to determine indoor air change rates (Andersen et al, 1997;Bornehag et al, 2005;Hirsch et al, 2000;Lembrechts et al, 2001;Øie et al, 1997, 1998Parker, 1986;Pandian et al, 1993;Ruotsalainen et al, 1992;Sakaguchi & Akabayashi, 2003).…”
