We have attempted to measure gaseous H 2 O 2 in air using an aqueous trapping method. With continuous bubbling, H 2 O 2 levels in the traps reached a plateau, indicating that a state of dynamic equilibrium involving H 2 O 2 destruction was established. We attribute this behavior to the interaction of ozone and its decomposition products (OH, O 3 − ) with H 2 O 2 in aqueous solution. This hypothesis was investigated by replacing the air stream with a mixture of N 2 , O 2 and O 3 . The results of this experiment show that H O was both produced and destroyed in the traps. These results have led us to question the validity of techniques which employ aqueous traps to measure H 2 O 2 in air.
