%X <p>Ozonation is a common remediation approach to eliminate odors from mold, tobacco and fire damage in<br />buildings. Little information exists to: 1) assess its effectiveness; 2) provide guidance on operation conditions;<br />and 3) identify potential risks associated with the presence of indoor ozone and ozonation byproducts. The goal<br />of this study is to evaluate chemical changes in thirdhand smoke (THS) aerosols induced by high levels of ozone,<br />in comparison with THS aerosols aged under similar conditions in the absence of ozone. Samples representing<br />different stages of smoke aging in the absence of ozone, including freshly emitted secondhand smoke (SHS) and<br />THS, were collected inside an 18-m3 room-sized chamber over a period of 42 h after six cigarettes were<br />consumed. The experiments involved collection and analysis of gas phase species including volatile organic<br />compounds (VOCs), volatile carbonyls, semivolatile organic compounds (SVOCs), and particulate matter.</p>
