Fragrant essential oils, derived from plants, may release various VOCs into the air. VOC degradation caused by the reaction of these compounds with ozone present in the air can produce small, ultrafine byproducts called secondary organic aerosols (SOAs), which may cause eye and airway irritation.
Taiwanese researchers Der-Jen Hsu (National Kaohsiung First University of Science and Technology), Hsiao-Lin Huang (Chia-Nan University of Pharmacy and Science, Tainan), and Shiann-Cherng Sheu (Chang-Jung Christian University, Tainan) tested both fragrant and Chinese herbal essential oils for SOA formation in a controlled-environment study chamber under different test conditions. They also performed air sampling and analysis in spa centers that offer massage therapy using essential oils.
The authors compared SOA levels associated for the various fragrant and herbal essential oils tested and present their results in the article, "Characteristics of Air Pollutants and Assessment of Potential Exposure in Spa Centers during Aromatherapy." They conclude that the layout and ventilation within a particular spa may affect the level of indoor air pollutants produced during massage with aromatherapy.
"Dr. Der-Jen Hsu and his colleagues have done a very nice job in bringing attention to often overlooked health risks associated with luxuries intended to enhance our sense of well-being," says Domenico Grasso, PhD Editor-in-Chief and Vice President for Research, Dean of the Graduate College, University of Vermont (Burlington).

Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.
Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...
Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.
Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...
Faster and secure data communication: This is the goal of a new joint project involving physicists from the University of Würzburg. The German Federal Ministry of Education and Research funds the project with 14.8 million euro.
In our digital world data security and secure communication are becoming more and more important. Quantum communication is a promising approach to achieve...
On Saturday, 10 November 2018, the research icebreaker Polarstern will leave its homeport of Bremerhaven, bound for Cape Town, South Africa.
When choosing materials to make something, trade-offs need to be made between a host of properties, such as thickness, stiffness and weight. Depending on the application in question, finding just the right balance is the difference between success and failure
Now, a team of Penn Engineers has demonstrated a new material they call "nanocardboard," an ultrathin equivalent of corrugated paper cardboard. A square...
