Get to Know PM2.5
What is PM2.5?
PM2.5 refers to particulate matter smaller than 2.5 microns in diameter. These particles are smaller than a strand of hair and cannot be filtered by nasal hair. They can enter the respiratory system, bloodstream, and even spread to different organs in the body, increasing the risk of illness and chronic diseases.
Common sources of PM2.5 include:
- Vehicle emissions
- Construction sites
- Industrial pollution
- Burning activities
- Fuel combustion
High-Risk Groups for PM2.5 Exposure
- 👶 Young children
- 🤰 Pregnant women
- 👴 Elderly people
- 😷 People with respiratory diseases
- ❤️ Patients with heart and cardiovascular diseases
