摘要：

A photochemical reaction mechanism for the description of air quality in Brazilian urban regions is described and evaluated by comparison with chamber experiments. The mechanism was developed for use in ozone modeling and application of control strategies. The oxidation of ethanol and methyl-ter-butyl-ether is also considered. Using this chemical model, a trajectory simulation of Brazil Avenue, Rio de Janeiro, was performed. The model predicts that ozone should reach a maximum of 22.4 ppb at 14:57 h, This value is in good agreement with the experimental measurements of 22.5 ppb for 14:00 h and 22.3 ppb for 15:00 h.
