The effects of evaporating essential oils on indoor air quality

The characterization of profiles and concentrations of emitted volatile organic compounds (VOCs) when essential oils evaporate indoors, is the aim of that study. Lavender, eucalyptus and tea-tree were tested on a nation-wide questionnaire survey. Specific aromatic compounds were sampled and analyzed by GC-MS. Particulate matters, CO, CO2, TVOCs were measured in real-time. The results show that only the PM level did not increase after the evaporating of the essential oils and high emissions of terpene were observed.
