The California Department of Public Health’s Occupational Health Branch has completed two studies conducting chemical analysis on car air fresheners and essential oils. The analysis were completed in partnership with the University of Melbourne, James Cook University, and RMIT University.
Both studies were published in the journal Air Quality, Atmosphere, and Health, and show “hundreds of unique volatile organic compounds (VOCs), including asthma-causing chemicals and many other hazardous compounds, were found among the 12 car air fresheners and 14 essential oils analyzed.” The Occupational Health Branch’s Work-Related Asthma Prevention Program has a web site with resources and policies to help address fragrances and work-related asthma.
