✦ Synopsis
To determine if Cu mediated reactions on atmospheric particles are important to HO,* chemistry in the ambient atmosphere, Cu molalities were calculated from measured Cu aerosol particle concentrations, mass and number size distribution data from a site in central Sweden. A comparison of characteristic times indicates that at low relative humidities the reaction is limited by the mass transport of gas phase HO,* to the particle surface and not by the chemical kinetics of the aqueous reaction. Comparison of half-lives for particle reactions and the gas phase destruction of HO,* to form H,O, indicate that heterogeneous reactions on aerosol particles may have important consequences on the chemistry of HO,*and H202 in the troposphere.
