A laboratory study has been conducted on heterogeneous reactions of nitrogen dioxide and nitric oxide to evaluate their potential role in reaction in polluted urban atmosphere. The results of this study suggest that nitrogen dioxide decomposes on a wide variety of solids likely to be found in urban environments. Measured reaction rates indicate these processes can be important in the atmosphere. Humidification of reaction mixtures leads to increased reactivities. It is concluded that heterogeneous reactions in the atmosphere are unimportant for the oxidation of nitric oxide.
