PM2.5 — Fine Particles

Particles smaller than 2.5 microns penetrate deep into lungs and bloodstream. High PM2.5 is linked to respiratory disease, heart conditions, and reduced cognitive performance in students.

NO₂ — Nitrogen Dioxide

Emitted by vehicles and generators near campus. NO₂ irritates airways, worsens asthma, and reduces lung capacity — especially harmful during outdoor sports and field activities.

UV Index — Solar Radiation

Guides when sunscreen is needed and when outdoor activities should be limited. Consistent UV exposure without protection raises long-term risk of skin damage and vision issues.

Campus Trees — Your Green Shield

Each registered tree actively absorbs CO₂, filters air pollutants, reduces surface temperature by up to 8°C, and provides a measurable health dividend to every person on campus.
