How Air Pollution Works in India
Learn the complete chain — from pollution sources and atmospheric chemistry to AQI systems, monitoring stations, health effects, and policy responses.
Start With These Essential Topics
What Is Air Pollution?
Learn the basics of air pollution, major pollutant types, and why AQI matters in Indian cities.
How AQI Is Calculated in India
Understand AQI formulas, breakpoints, pollutant weighting, and CPCB AQI methodology.
CAAQMS Monitoring Systems
Explore how real-time air quality monitoring stations measure pollutants.
Primary vs Secondary Pollutants
Learn how pollutants form in the atmosphere and influence AQI patterns.
Health Effects of Air Pollution
Discover how air pollution affects lungs, heart health, and long-term disease risk.
Most Polluted Cities in India
Understand why Delhi and other cities experience severe AQI episodes.
Air Pollution Is a Major Public Health Risk
Air pollution affects health, visibility, ecosystems, climate systems, and urban quality of life across India.
PM₂.₅ Exposure
Fine particles penetrate deep into the lungs and bloodstream, increasing long-term health risks.
Winter Smog
Temperature inversion and stagnant weather trap pollutants near the surface during winter.
Monitoring Networks
CPCB monitoring stations continuously measure pollutants and calculate AQI values.
