Study of seasonal pollutant trends key to tackling air pollution: Data

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. Instead of just looking at one general "pollution score," they say we must look at each chemical separately to fix the problem.

For example, soot and dust (PM2.5) are worst in the winter because the cold air traps them near the ground. However, other gases like Ozone and Nitrogen Dioxide actually get worse during the hot summer months. By understanding these "fingerprints," the government can better target the actual sources—like cars, power plants, or construction dust—at the right time.
