The proposed Arrhenius expressions are k(1) = (6.2 +/- 7.5) x 10(-11) exp -(2826 +/- 866)/T (cm(3) molecule(-1) s(-1)), k(2) = (1.7 +/- 1.0) x 10(-11) exp -(2250 +/- 192)/T (cm(3) molecule(-1) s(1)), k(3) =(7.6 +/- 9.8) x 10(11) exp -(2466 +/- 505)/T (cm(3) molecule(-1) s(-1)), k(4) = (2.8 +/- 1.4) x 10(-11) exp -(2189 +/- 156)/T (cm(3) molecule(-1) s(-1)), k(5) = (7.0 +/- 1.8) x 10(-11) exp -(2382 +/- 998)/T (cm(3) molecule(-1) s(-1)), and k(6) = (7.8 +/- 1.0) x 10(-11) exp -(2406 +/- 481)/T (cm(3) molecule(-1) s(-1)).Tropospheric lifetimes for these aldehydes were calculated at night and during the day for typical NO3 and OH average concentrations and showed that both radicals provide an effective tropospheric sink for these compounds and that the night-time reaction with the NO3 radical can be an important, if not dominant, loss process for these emitted organics and for NO3 radicals.
