Dust is composed of larger and smaller particles suspended in the air. While larger particles may sting and irritate your eyes, smaller particles are of most concern to people's health because they can lodge deep into your lungs and harm your health.
The dust storm mixture is made up of large and tiny particles, known as particulate matter. The smallest particles, known as PM10 and PM2.5, are too small to be filtered out by your nose and your body's other natural defense systems. This fine dust is inhaled deep into your lungs where it can cause increased problems with:
- Lung irritation.
- Heart disease.
- Allergic reactions.
Breathing too much dust is especially harmful to:
- Infants, children, teens, the elderly, and pregnant women.
- People with asthma, bronchitis, emphysema, or other respiratory conditions.
- People with heart disease.
- Healthy adults working or exercising outdoors.
