Ammonium Sulphate Dominates Delhi's Deadly PM2.5 Pollution
Delhi has a big problem with air pollution, especially tiny particles called PM2.5.
Scientists have found that one-third of these particles are made of a chemical called ammonium sulphate.
This chemical can cause serious health problems like breathing difficulties and heart issues.
The study shows that it's not just the amount of pollution that matters, but also what it's made of.
This helps us understand why Delhi's air is so harmful and how we can protect people's health.
Ammonium sulphate makes up nearly one-third of Delhi's annual PM2.5 pollution.
This pollutant is linked to serious respiratory and heart-related health risks.
The study highlights the importance of pollution composition, not just quantity.
Research was conducted by the Centre for Research on Energy and Clean Air (CREA).
Understanding the composition of pollution can help in developing better health protection measures.
