39 unreported and major human-made sources of toxic sulphur dioxide (SO2) emissions have been placed by NASA scientists using a new satellite-based method which are causes pollution.

  • From 2005 to 2014 the unreported emission sources were create in the analysis of satellite data.
  • These sources are sets of coal-burning power plants, oil and gas actions and smelters mainly found in West Asia, Mexico and parts of Russia.
  • SO2 is an identified health exposure and source of acid rain.
  • Presently, SO2 detecting an activities contain the use of construction records that are resulting from ground-based quantities and factors, such as fuel usage.

Key facts

  • The satellite-based estimations of the productions were 2 or 3 times higher than those described from known foundations in these regions.
  • 12 % of all human-made emissions of SO2 accounted by the unreported and under-reported sources.
  • This inconsistency may have large effect on regional air quality.
  • 75 natural sources of SO2 have been located by Investigators using a new satellite in the form of non-erupting volcanoes that are gradually leaking the contaminated gas.
