Abstract
Concentrations of airborne continuous fine particulate matter
or (PM2.5), 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 PM2.5 were also measured continuously. All 4 continuous
instruments employed performed well both in laboratory and
field conditions. Mean outdoor concentrations of PM2.5, 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 PM2.5 staying about the same. Between
5:00 pm and 7:00 pm, indoor UFP and PM2.5 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 (R2 = 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.
