Abstract

The authors thank the school districts and schools participating in the Children's Health Study (California Air Resources Board Contract A033-186), for their cooperation, and for the use of facilities; Mahnaz Hakami for laboratory assistance; Barbara Zielinska for help with the sampling design; and Janet Arey, Roger Atkinson, James N. Pitts Jr., and Richard Kamens for helpful discussions and insights. Finally, we thank the reviewers for their very helpful suggestions. This research was supported by the Southern California Particle Center and Supersite (USEPA Grants #R827352-01-0 and CR-82805901). Additional investigator support (E. A. A. H. M., and A. E.-F.) was provided by a NIEHS Center Grant (SP30ES07048-02).

In situ measurements of gas/particle-phase transitions for atmospheric semivolatile organic compounds

“…This trend is expected for many gas-phase compounds undergoing oxidation in the atmosphere, creating lower-volatility reaction products and forming SOA. The quantity of naphthalene observed in the particle phase here is similar to the annual average observed previously at Riverside (6.72 AE 11.6 ng m −3 ), where naphthalene was found to be approximately 1% in the particle phase and 99% in the gas phase (22).…”

PAHs accumulation on leaves of six evergreen urban shrubs: A field experiment

“…The reason being that it was decided to sample the leaves in periods when the PAHs are not photodegraded or volatilized due to the atmospheric conditions (Halsall et al, 2001). We are thus unable to describe the fluctuations of the lighter compounds due to volatilisation and photodegradation as described in the literature by Eiguren-Fernandez et al (2004) and Lodovici et al (2003). However, we demonstrated that the accumulation of BbF, BkF and BaP occurred more evidently in leaves in L. japonicum, Elaeagnus x ebbingei and I. aquifolium.…”

Review of Recent Advances in Detection of Organic Markers in Fine Particulate Matter and Their Use for Source Apportionment

“…For example, tracers for motor vehicle exhaust include higher-molecular-weight PAHs such as benzo[ghi]perylene, which is more associated with gasoline exhaust. 62 On the other hand, as previously mentioned, two PAHs (fluoranthene and pyrene) have been identified as molecular markers for separating diesel and gasoline PM on the basis of pollutant emission data collected in a roadway tunnel. 23 Moreover, PAH concentration diagnostic ratios can be used as an indicator for distinguishing emissions from catalyst and noncatalyst automobiles.…”
