Purdue Study: Scented Cleaners Create Invisible Nanoparticle Pollution Rivaling Highway Smog
Research from Purdue University indicates that using scented cleaning products indoors generates billions of ultrafine nanoparticles through reactions between terpenes and ozone. These particles, ranging from 1 to 30 nanometers, are small enough to bypass standard air monitors and penetrate deep into lung tissue, potentially exposing users to respiratory doses comparable to or exceeding those found on busy city streets.
