The Origins of Ultrafine Particles
Airborne particles originate from many natural and man-made sources (e.g. sand, dust, fire, diesel smoke, sea salt). Ultrafine particles are generated at very high temperatures, such as combustion processes, including wood fires, car engines, industry work, cooking fumes, and cigarette smoke.
Potential Health Hazards
- Ultrafine particles penetrate deep into the lungs. The high concentration of these particles makes it more challenging for the lungs to process, which leads to inflammation.
- These particles are small enough to enter the cells in the body and end up in the bloodstream, potentially causing heart and brain diseases. Children, elderly people, and people with lung issues, like asthma, are especially vulnerable to ultrafine particle air pollution.
