Pulmonary Effects of Ozone-generating Air Purifiers Otana Jakpor

  title={Pulmonary Effects of Ozone-generating Air Purifiers Otana Jakpor},
  author={Otana A. Jakpor},
Air purifiers are marketed to asthmatics and others to improve breathing. However, some air purifiers emit harmful ozone—a key component of smog. This study examines the hypothesis that ozone-generating air purifiers and other household devices that generate ozone may have a negative effect on pulmonary function. According to a recent study by the California Air Resources Board, 10% of California households own an air purifier that may produce ozone. No published studies on the direct pulmonary… 

Absorption Cross Section Simulation: a Preliminary Study of Ultraviolet Absorption Spectroscopy for Ozone Gas Measurement

Preliminary study to measure gaseous ozone concentration using ultraviolet absorption spectroscopy is presented. Firstly, background of ozone is introduced. Next, fundamental theory behind



Quantification of Ozone Levels in Indoor Environments Generated by Ionization and Ozonolysis Air Purifiers

Several types of air purifiers were tested for their ability to produce ozone in various indoor environments at 40-50% relative humidity, including office rooms, bathrooms, bedrooms, and cars, where O3 concentrations were well in excess of public and/or industrial safety levels established by U.S. Environmental Protection Agency, California Air Resources Board, and Occupational Safety and Health Administration.

Indoor exposures to ozone and its oxidation products can be reduced by filtering ozone from ventilation air and limiting the indoor use of products and materials whose emissions react with ozone.

The Exposure–Response Curve for Ozone and Risk of Mortality and the Adequacy of Current Ozone Regulations

The findings indicate that even low levels of tropospheric O3 are associated with increased risk of premature mortality, and interventions to further reduce O3 pollution would benefit public health, even in regions that meet current regulatory standards and guidelines.

Interpretative strategies for lung function tests

This section is written to provide guidance in interpreting pulmonary function tests (PFTs) to medical directors of hospital-based laboratories that perform PFTs, and physicians who are responsible for interpreting the results of PFTS most commonly ordered for clinical purposes.

Survey of the use of ozone-generating air cleaners by the California public

The authors wish to thank all of the participants in this study for taking the time to complete the telephone questionnaire.
