About Nitrate radicals:
- Nitrate radical is an oxide of nitrogen that consists of three oxygen atoms bound to a nitrogen atom.
- These radicals could increase the amount of unhealthy ozone and PM2.5 fine particulate matter in the atmosphere.
- Nitrate radicals will oxidise gas pollutants such as volatile organic compounds (VOCs).
- These VOCs will then generate ozone and secondary organic aerosol, both deteriorates air quality.
- The Ozone is an air pollutant that affects human health and crop yield.
- The synthesis of nitrate radicals rises at night in some regions of India, particularly in northern India.
- Reducing the emissions of VOCs could reduce this night-time oxidation in India and China.
