The reaction probability of ozone on the surface of several different organic liquids is measured. Ozone reacts efficiently (γ≈10 −2 ‐10 −3 ) with organic liquids containing double bonds (1‐tridecene, α‐pinene, toluene, methacrolein and canola oil), and much less efficiently with an aldehyde, a ketone (tridecanal, 2‐tridecanone; γ≈10 −4 ), an alkane, an alcohol and an acid (tridecane, 1‐tridecanol, tridecanoic acid; γ≤10 −5 ). The results suggest that heterogeneous reactions with organic aerosol can be an important loss process for tropospheric ozone, if the aerosol contains unsaturated organic material.
