PM2.5 — Fine Particles
Particles smaller than 2.5 microns penetrate deep into lungs and bloodstream. High PM2.5 is linked to respiratory disease 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 activities.
UV Index — Solar Radiation
Guides when sunscreen is needed and when outdoor activities should be limited. Consistent UV exposure raises long-term risk of skin 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.
