They also investigated what would happen when ozone was introduced into the environment. Ozone can enter homes through open windows. In addition, it can be created by laser printers and 3D printers.
They found that when personal care products were used indoors in the presence of ozone, the VOCs went through oxidation reactions to form various gas-phased vapors, which led to rapid new particle formation (NPF) events. The particle growth rates were up to 10 times higher than the rates of NPF events outdoors.
It is crucial to take the proper measures to reduce the reaction between VOCs and ozone. The researchers recommend improving ventilation and using these products less.
“I know this is difficult to hear, but we’re going to have to reduce our reliance on these products, or if possible, replace them with more natural alternatives that contain fragrant compounds with low chemical reactivity,” said Licina.
“Another helpful measure would be to raise awareness of these issues among medical professionals and staff working with vulnerable groups, such as children and the elderly.”
The study was published in the journal Environmental Science & Technology Letters.
