Summary
New research from South Korea shows that small household appliances like hairdryers, toasters, and air fryers can release high levels of tiny particles that may be harmful to health. These particles, often made of heavy metals, can settle deep in the lungs and pose greater risks to young children. The study suggests that using devices with brushless motors or different heating elements could reduce exposure to these particles.
Key Facts
- Small appliances with electric heating coils and brushed DC motors emit ultrafine particles (UFPs).
- UFPs can reach deep into the lungs, posing health risks, especially for children.
- Hairdryers, toasters, and air fryers are significant sources of these particles.
- Appliances with brushed motors release up to 100 times more particles than brushless ones.
- Heavy metals like copper, iron, and aluminum were found in the emitted particles.
- UFPs tend to accumulate in the deepest parts of the lungs, increasing health risks.
- Children are more vulnerable due to smaller airways and greater deposition per body weight.
