A new study from Lawrence Berkeley National Laboratory suggests that ozone generators may help remove harmful thirdhand smoke residues from indoor surfaces. However, the study also found that ozone generators can produce a burst of contaminants when they are running, and that particles can remain airborne for a period of a few hours after ozonation.
The study, which was conducted on freshly generated thirdhand smoke, found that ozone removed nicotine and polycyclic aromatic hydrocarbons (PAHs) that had adsorbed onto fabrics after smoking. However, the study authors caution that people need to wait a few hours after the generator has run and allow the space to be ventilated before going back inside.
The researchers next plan to study the effects of ozonation on materials that have been contaminated with thirdhand smoke for longer periods of time. They also plan to investigate the potential health risks associated with exposure to ozone and ozone byproducts.
What is thirdhand smoke?
Thirdhand smoke is the residual contamination from tobacco smoke that remains on surfaces long after the smoke has cleared. It can contain hundreds of harmful chemicals, including nicotine, PAHs, and volatile organic compounds (VOCs).
How does ozone work to remove thirdhand smoke residue?
Ozone is a powerful oxidizer that can break down and destroy many of the chemicals found in thirdhand smoke. When ozone is applied to a surface, it reacts with the chemicals and converts them into less harmful substances or gases that can be released into the air.
What are the risks associated with ozone exposure?
Ozone is a lung irritant that can cause coughing, wheezing, and shortness of breath. Exposure to high levels of ozone can also damage the lungs and increase the risk of respiratory infections.
How can I safely use an ozone generator to remove thirdhand smoke residue?
If you are considering using an ozone generator to remove thirdhand smoke residue from your home, it is important to take the following precautions:
- Only use an ozone generator in unoccupied spaces.
- Follow the manufacturer’s instructions carefully.
- Ventilate the space thoroughly after using the ozone generator before re-entering.
- Be aware of the potential health risks associated with ozone exposure and take steps to minimize your exposure.
Conclusion
Ozone generators may be a helpful tool for removing thirdhand smoke residue from indoor surfaces. However, it is important to use them safely and to be aware of the potential health risks associated with ozone exposure.
