Finding F-1241

“Despite overall low indoor ozone concentrations (mean value of 4.3 ppb) and a relatively low indoor ozone decay constant (1.3 h−1), we identified multiple VOCs exhibiting clear contributions from ozone-initiated chemistry indoors.”

Structure

Factor: Ozone (O₃)
Population: two adult inhabitants of the house
Setting: home, US
Study design: eight-week summer campaign in a normally occupied single-family house in California with two adult inhabitants: space- and time-resolved measurements of ozone and of volatile organic compounds by proton transfer reaction time-of-flight mass spectrometry in the living space, in the crawlspace and outdoors, with the indoor source strength of each compound regressed against the indoor ozone concentration (class 4)
Effect: mean 4.3
Caveat: one house in California over one summer; the study calls the level low and the decay constant relatively low, and still finds several volatile compounds formed by ozone chemistry indoors
