Abstract: Recent studies associate particulate air pollution with adverse health effects; however, the exposure to indoor particles of outdoor origin is not well characterized, particularly for individual chemical species. We conducted a field study in an unoccupied, single-story residence in Clovis, California to provide data and analyses to address issues important for assessing exposure. We used real-time particle monitors both outdoors and indoors to quantify PM-2.5 nitrate, sulfate, and carbon. The results show tha… Show more

“…Particulate OM (corrected for artifacts) constituted 48%, 54% and 61% of PM 2.5 mass inside Los Angeles Co., Elizabeth and Houston study homes, respectively. While PM 2.5 nitrate was not measured in RIOPA, Los Angeles Co. species mass balance results are consistent with large nitrate losses during outdoorto-indoor transport, as reported by Lunden et al (2003). This suggests that dramatic changes in the mass and composition of outdoor-generated PM 2.5 can occur with outdoor-to-indoor transport in areas where nitrate is a major component of PM 2.5 (e.g., California).…”

“…This difference was particularly pronounced on high PM 2.5 days (Figure 4). Since the largest component of ''other'' is expected to be ammonium nitrate, this finding is consistent with modeling and controlled experimental results reported by Lunden et al (2003). They suggested that losses of nitric acid to indoor surfaces drive a redistribution of nitrogen from the particle phase (ammonium nitrate) to the gas-phase (nitric acid), as it is transported indoors from outdoors.…”

“…30 Scenario c, which represents a northeastern US near-roadway scenario, is enriched in OC and EC based on the near-roadway measurements of Lena et al 33 Particle composition is taken into account in our calculations of F through the use of species-specific deposition loss rates and by accounting for the semivolatile nature of nitrate. The value for k evap;NO À 3 is from the work of Lunden et al 34 and Hering et al, 29 and involves the temperature-dependent equilibrium constant for ammonium nitrate dissociation (see details in Supplemental Information). Other PM components, including organic PM, were treated as non-volatile.…”

“…A sensitivity analysis was performed by conducting robust regression on RIOPA data from one California home (CA239) after adding indoor and outdoor nitrate concentrations from another California study (43) with similar atmospheric conditions. Robust regression results were unchanged with the addition of nitrate.…”
