The study shows that air pollution in India changes with the seasons, and each pollutant behaves differently. Tiny particles like PM2.5 and PM10 are highest in winter, while gases like ozone and nitrogen dioxide tend to rise in summer.

An environmental group called Envirocatalysts has created a new online tool to help people track air pollution across India.

A decade-long study on India's air quality reveals distinct seasonal patterns for various pollutants like PM2.5, NO2, and ozone.

Experts have looked at ten years of air quality data in India and found that different types of pollution peak at different times of the year.
