A “Tiny House” Study of Indoor Air
At Purdue University, researchers are using “tiny house” units as a way of measuring the amount and duration of nanoparticles that are formed from many different household products. They have discovered that products like wax-melt units, floor chemicals, deodorants, candles (especially scented) and room fresheners send petroleum and chemical scents into the air which interact with ozone to form these particles which are tiny enough to enter our lungs and eventually other organs.
Nanoparticles from hair spray products tend to remain suspended for a very long time. Cooking on a gas stove also emits nanoparticles. Even essential oil diffusers emit particles. In a closed home, especially during the winter, the amount of exposure to nanoparticles can be huge (think of combinations—as much as one billion nanoparticles). These researchers just measure exposure. They encourage others to research the amount of damage these nanoparticles are causing.
