Scented Candles: Indoor Air Pollution Rivals Car Exhaust
New research from Purdue University reveals that using scented products indoors significantly alters air chemistry, producing air pollution comparable to car exhaust. Using a miniature 'tiny house lab,' researchers measured nanoparticles released by flameless candles, finding alarmingly high concentrations capable of reaching deep into the lungs and posing respiratory health risks. These nanoparticles reached levels comparable to those emitted by traditional candles, gas stoves, and even vehicle exhaust, with billions of particles deposited in the respiratory tract per minute. The study underscores the importance of indoor air quality and suggests considering these factors in building design and ventilation systems to mitigate health risks.
