Gas-particle distribution

The extent of gas-to-aerosol conversion of secondary pollutants can be estimated by measuring gas particle distribution factors for carbon, nitrogen, and sulfur species. For example, /c = P/ P + G), where P = particulate organic carbon ng/m as carbon) and G = gas-phase... [Pg.52]

Because of such real-world nonequilibrium situations, some efforts, for example, by Turco and coworkers (Jacobson et al., 1996), Kamens and co-workers (Odum et al., 1994), and Seinfeld and co-workers (Bowman et al., 1997), have focused on developing dynamic models to describe gas-particle distributions.

Correlation of logKp vs. log p([ have been explained as a combination of both adsorption to the surface of the particle and absorption into an organic surface layer [59]. More recently partitioning to the surface of soot carbon has been suggested as playing an important role in this gas/particle distribution [60]. While the relative importance of these mechanisms remains unclear, the overall behavior can be summarized by the following equation [59] ... [Pg.321]
