The popular fragrant wax, after all, is as or more harmful than traditional candles. New study also draws attention to the dangers of oil diffusers, environmental and disinfectant.
The melting of fragrant wax – which are the most popular, for houses – contributes to inner air pollution at levels comparable to those of diesel and gas stoves, according to a study on February 3 at Environmental Science & Technology Letters.
Investigators from the United States and Germany have found that these products, although they do not produce flame, issue volatile organic compounds (COV), in particular terpenóideswhich interact with the ozone to form tiny particles.
The formation of these particles, known as nanoclusters aerosolscan lead to air quality problems. Although the effects of these particles on health are not yet fully understood, they are small enough to penetrate deeply in the lungs. It cites one of 2021 that associated these particles with respiratory and cardiovascular problems.
Using advanced equipment, including a high resolution magnifying glass to measure particle size and a massent of mass, the team managed to see how fragrances react with the ozone to form nanoparticles in closed environments that grow and evolve in the air.
Although melted waxes are often marketed as a cleaner alternative to traditional candles because they have no flames or combustion, the study shows that can be equally harmful if no longerwith regard to air pollution. The melted wax releases a higher concentration of POV compared to candles, as they have a larger surface and more fragrance.
The results suggest that, After only 20 minutes of exposure, one person can inhale thousands of millions of nanoparticles, with any risks – still unknown – to health.
In addition, fragrant products are more than simplemakers – actively alter the chemistry of inner air. The study draws attention to the fact that inner air pollution is often neglected.
Researchers also drew attention to other fragrant products, such as Oil Diffusers, Settings and Disinfectantswhich proven to contribute to nanoparticle pollution.
