Scientists at the Aryabhatta Research Institute of Observational Sciences (ARIES), Nainital have found that the concentration of near surface ozone in this region in the North-East corner of India is low compared to the other urban locations in India.
- They evaluated the near surface ozone in the Brahmaputra River Valley (BRV) and found relatively low concentration of Ozone over Guwahati compared to the other urban locations in India.
- Their present work has been published recently in the journal ‘Atmospheric Pollution Research’.
- Tropospheric, or ground-level ozone, is created by chemical reactions between oxides of nitrogen (NOx) and volatile organic compounds (VOC).
- It usually increases when pollutants emitted by cars, power plants, industrial boilers, refineries, chemical plants, and other sources chemically react in the presence of sunlight, impacting human health.
