Points to Remember:
- India is the world’s largest emitter of anthropogenic sulphur dioxide, which is produced from coal burning, and greatly contributes to air pollution.
- According to an analysis of a National Aeronautics and Space Administration (NASA) data released by environmental NGO Greenpeace, India has more than 15 percent of all anthropogenic sulphur dioxide (SO2) hotspots in the world detected by the OMI (Ozone Monitoring Instrument) satellite.
Major hotspots in India
- The major SO2 emission hotspots in India are Singrauli in Madhya Pradesh, Neyveli and Chennai in Tamil Nadu, Talcher and Jharsuguda in Odisha, Korba in Chhattisgarh, Kutch in Gujarat, Ramagundam in Telangana and Chandrapur and Koradi in Maharashtra.
- The NASA data also highlights other hotspots across the globe, with the Norilsk smelter complex in Russia being the largest SO2 emission hotspot in the world, followed by Kriel in Mpumalanga province in South Africa and Zagros in Iran.
Sulphur dioxide significant contributor to air pollution
- The report said SO2 emissions are a significant contributor to air pollution. The largest source of SO2 in the atmosphere is the burning of fossil fuels in power plants and other industrial facilities.However, as per country-wise world rankings, India was found at the top position in emitting SO2 as it has the maximum hotspots.
Important Possible questions based on above News:
- which nation is on the top position in emitting anthropogenic sulphur dioxide, as per the latest data released by environmental NGO Greenpeace. India
- What is the name of the satellite that detects anthropogenic sulphur dioxide (SO2) hotspots in the world? OMI (Ozone Monitoring Instrument)
