Figure 2. Kinetic results for uncoated and benzo[e]pyrene (BeP)-coated soot.

Figure 2

(a) Pseudo-first order rate constants for the fast loss process (1) observed in PAH (polycyclic aromatic hydrocarbon) decay as a function of O3 concentration for the reactions with total PAHs on soot (black circles) and BeP on soot (red triangles). Data were fitted to equation 1. (b) Uptake coefficients calculated from the data in the upper graph using equation 2 as a function of O3 concentration. Data were fitted to equation 3. Every point corresponds to one experiment. Error bars represent one standard deviation.
