Home Appliances Emit Harmful Airborne Particles
A new study found that common home appliances like toasters, air fryers, and hair dryers release tiny, harmful particles into the air.
These particles are so small they can enter our lungs and even our blood.
The study showed that empty toasters release the most particles, while certain hair dryers release bursts of particles.
These particles can contain heavy metals like copper and iron, which can make people sick.
The researchers say we need better guidelines to keep our indoor air clean and safe, especially for kids.
They hope this study will help make appliances that release fewer harmful particles.
Home appliances like toasters, air fryers, and hair dryers emit trillions of ultrafine particles (UFPs).
Empty pop-up toasters release approximately 1.73 trillion UFPs per minute, the highest among tested appliances.
Hair dryers with brushed DC motors emit more particles than brushless models.
UFPs can penetrate deep into the lungs and bloodstream, posing health risks like asthma and cardiovascular disease.
Researchers found heavy metals such as copper, iron, and aluminium in the emitted particles.
