A Modelling Study of Indoor Air Chemistry: The Surface Interactions of Ozone and Hydrogen Peroxide

A measurement and modelling investigation of the indoor air chemistry following cooking activities

“…34,39 Following deposition of O 3 and/or H 2 O 2 , there is surface-dependent emission of aldehydes, based on Carter et al , 2023. 39…”

“…40, and outlined in ref. 39. The surface area to volume ratios for each of the materials considered in the model are as follows, assuming one adult (2 m 2 ) is in the room: soft furnishings = 0.081 m −1 ; paint = 0.992 m −1 ; wood = 0.665 m −1 ; metal = 0.311 m −1 ; concrete = 0.048 m −1 ; paper = 0.008 m −1 ; plastic = 0.290 m −1 ; glass = 0.058 m −1 ; and skin = 0.080 m −1 .…”

“…However, for O 3 and hydrogen peroxide (H 2 O 2 ), the deposition velocity is dependent on the surface material, with specic SAVs given for metal, glass, wood, plastic, paint, paper, concrete, so furnishing and skin. 34,39 Following deposition of O 3 and/or H 2 O 2 , there is surface-dependent emission of aldehydes, based on Carter et al, 2023. 39 2.5.1 Simulating cooking experiments.…”

“…34,39 Following deposition of O 3 and/or H 2 O 2 , there is surface-dependent emission of aldehydes, based on Carter et al, 2023. 39 2.5.1 Simulating cooking experiments. To investigate the production of secondary species in a typical environment, the cooking experiments were simulated in an average kitchen.…”

“…The concentrations of gases outdoors are split into species with diurnally varying concentrations (O 3 , NO and NO 2 ) and 110 VOCs with static outdoor concentrations. 39 Data from the European Air Quality Database, from the 'GB0586A, suburban London, 0.070766 51.45258' monitoring station were used, from which average hourly concentrations were calculated from measurements taken over a 3 month period (July, August and September) for O 3 , NO and NO 2 . 41 The indoor background VOC concentrations are determined by the outdoor concentrations and the ACR.…”
