The reaction probability decreases by 7% 35 to 47% across the three test materials after two 8-h periods of ozone exposure. Measurements 36 with the samples from an occupied office reveal that deposition velocity can decrease or increase 37 with time. Influence of temperature and humidity on ozone-surface reactivity was not strong.

Indoor gaseous air pollutants determinants in office buildings—The OFFICAIR project

“…Significant positive relationships were found between several IAPs and indoor air temperature (ethylbenzene, 2‐butoxyethanol, 2‐ethylhexanol, styrene, acetaldehyde, and hexanal) or indoor relative humidity (2‐butoxyethanol and hexanal). This finding is consistent with previous studies, which outlined that higher temperature may increase indoor material emissions and that the emission of VOCs and aldehydes is influenced by environmental factors such as temperature and humidity, to different degree for various materials . Moreover, RH could also affect ozone‐initiated terpene reactions, causing an increase in the formation of reaction products such as hexanal …”

Impact of surface ozone interactions on indoor air chemistry: A modeling study

“…Distribution of reported ozone deposition velocity onto different indoor surfaces, considering number of measurements (n) for each. The box and whisker plot shows the minimum, 25‰, median, 75‰ and maximum values in cm s −1 …”

Passive removal materials for indoor ozone control

“…Results were generally in good agreement with those for the same materials tested by Lamble et al [72] and Cros et al [48]. Rim et al [130] measured ozone deposition velocities for three different indoor materials (a synthetic fiber carpet, latex paint on mineral fiber ceiling tile, and mold-guard paint on drywall) while simulating diurnal ozone conditions (high concentrations during the day, zero concentration at night). Ozone reaction probabilities were determined for fresh materials and for the same materials after 1 and 2 months of placement in an occupied office building.…”

“…For perlite ceiling tile, however, ozone deposition velocity was moderate (2.3 m h À1 ), and molar yields of carbonyls were low (0.03). No consistent trends in ozone deposition and byproduct emissions were observed with changes in relative [50] zero-VOC paint on gypsum board, perlite ceiling tile, recycled carpet O 3 & carbonyl byproducts Lab Gall et al [129] Cellulose filter papers, AcC cloth, pervious pavement, Portland cement concrete O 3 Lab Rim et al [130] Mineral fiber ceiling tile, mold-guard paint on drywall, and carpet tile O 3 Lab humidity across all materials.
